Developmental and epileptic encephalopathy 87 is a rare genetic condition that usually begins in infancy or early childhood. It causes seizures and can affect development, learning, movement, and muscle tone. Not everyone will have the same experience, but early symptoms of Developmental and epileptic encephalopathy 87 often include hard-to-control seizures and delayed milestones. Developmental and epileptic encephalopathy 87 is usually lifelong, and some children have serious complications that can shorten life expectancy. Treatment focuses on seizure control and supportive care, which may include anti-seizure medicines, therapies, feeding support, and regular follow-up with specialists.
How many people live with Developmental and epileptic encephalopathy 87?
Developmental and epileptic encephalopathy 87 is so rare that no reliable worldwide estimate is available, and sources such as OMIM and Orphanet do not list a clear global count for people living with it. The same is true in the United States, where no dependable published estimate is available and only a small number of cases have been described in the medical literature.
Overview
Developmental and epileptic encephalopathy 87Symptoms
Developmental and epileptic encephalopathy 87 often causes early-life seizures, delayed development, and low muscle tone. Many children also have feeding problems, movement or balance difficulties, and learning impairment, though features can vary.
Outlook and prognosis
Developmental and epileptic encephalopathy 87 often begins early and can affect seizures, learning, movement, and daily independence over time. Outlook varies, but many living with developmental and epileptic encephalopathy 87 need ongoing specialist care and long-term developmental support.
Causes and risk factors
Developmental and epileptic encephalopathy 87 is caused by a change in the CDKL5 gene, usually new rather than inherited. Risk factors are mainly genetic. Lifestyle or environmental factors do not cause it, though they can affect complications and day-to-day symptoms.
Genetic influences
Genetics are central to Developmental and epileptic encephalopathy 87, which is caused by harmful changes in the HECW2 gene. These genetic variations usually arise new in the child, though rarely they can be inherited.
Diagnosis
Developmental and epileptic encephalopathy 87 is usually diagnosed by combining seizure history, developmental findings, brain wave testing, and exam results. The genetic diagnosis of Developmental and epileptic encephalopathy 87 is confirmed with genetic testing, sometimes alongside brain imaging.
Treatment and drugs
Treatment for developmental and epileptic encephalopathy 87 focuses on controlling seizures and supporting development. Many need anti-seizure medicines, regular neurology follow-up, and therapies for movement, feeding, learning, or communication. Care is tailored because symptoms and seizure patterns can vary.
Symptoms
Developmental and epileptic encephalopathy 87 often becomes noticeable very early in life, when seizures and delayed milestones begin to affect feeding, movement, and learning. The early features of developmental and epileptic encephalopathy 87 often include repeated seizures along with slower progress in skills such as head control, sitting, speech, or walking. Features vary from person to person and can change over time.
Seizures are often the first clear sign and may begin in infancy or early childhood. They can look like staring, stiffening, jerking, sudden drops, or spells with reduced awareness.
Many children with developmental and epileptic encephalopathy 87 reach milestones later than expected, such as rolling, sitting, walking, or talking. Some may also gain skills more slowly over time, especially when seizures are frequent.
Low muscle tone can make it harder to hold the head up, sit steadily, or move smoothly. Some children also develop stiffness or coordination problems that affect walking and hand use.
Speech may be very limited, and understanding language can also be affected. For many people with developmental and epileptic encephalopathy 87, learning support is needed from early childhood.
How people usually first notice Developmental and epileptic encephalopathy 87?
Developmental and epileptic encephalopathy 87 is usually first noticed in infancy or early childhood, often when families or doctors see seizures, unusual body stiffening or jerking, or episodes where a baby seems less alert or stops responding normally. The first signs of developmental and epileptic encephalopathy 87 can also include delayed milestones, such as slower head control, rolling, sitting, or speech development, along with low muscle tone or feeding difficulties. Because early signs can vary, some children are first recognized after repeated seizures, while others are noticed when development does not move forward as expected at routine checkups.
Types of Developmental and epileptic encephalopathy 87
No distinct types of Developmental and epileptic encephalopathy 87 are widely recognized.
Can I slow down the onset of symptoms?
For developmental and epileptic encephalopathy 87, there is currently no good evidence that lifestyle changes or medical treatment can meaningfully delay when symptoms begin; this is a rare genetic brain condition, and symptoms usually start because of the underlying gene change, not because of diet, exercise, sleep, or anything a family did or did not do. There is also no proven preventive medicine to stop it from starting, although early follow-up with a neurology team and genetic counseling for families can help catch seizures and developmental changes sooner and guide care. While this may not prevent the condition, early support can still make a real difference in day-to-day care and planning.
What genetics can tell you about symptoms
In developmental and epileptic encephalopathy 87, genetics can help explain why symptoms may differ from one person to another, including which seizure patterns appear, how much development is affected, and when problems begin. Some genetic changes linked to this condition are associated with earlier onset, more severe epilepsy, or added features such as low muscle tone, feeding difficulties, or learning and movement problems, but there is still a wide range from mild to more serious symptoms. Even so, a genetic result cannot predict every detail, and many living with the same condition can have different day-to-day challenges.
Causes and risk factors
Early seizures and slower development in Developmental and epileptic encephalopathy 87 usually come from a harmful gene change that affects brain signaling. That change may be inherited from a parent, but many cases happen for the first time in the child. Fever, infections, and sleep loss can make seizures easier to trigger, but they do not cause the condition itself. Family history can matter, and missed medicines or other daily stresses can worsen seizure control in Developmental and epileptic encephalopathy 87. Risk can vary widely from person to person, so genetic counseling can help families understand the chance of it happening again.
What are the most common causes or risk factors?
Developmental and epileptic encephalopathy 87 is mainly caused by a harmful change in one gene that affects how brain cells work and send signals. In many living with this condition, the gene change happens for the first time in the child and is not caused by anything a parent did before or during pregnancy, although it can sometimes be passed down in a family. There are no known common lifestyle, diet, or environmental risk factors.
Environmental and biological risk factors
For many families searching for known environmental risk factors for Developmental and epileptic encephalopathy 87, the honest answer is that very few have been clearly confirmed. Awareness of both biological and environmental influences helps you feel prepared. Because this condition is rare, doctors usually review pregnancy history, birth history, and major exposures, while also noting that many suspected factors have not been proven to cause it.
Older paternal age is one of the few biological factors sometimes linked with a higher chance of rare developmental conditions present from birth. For Developmental and epileptic encephalopathy 87, this may be relevant, but no exact age cutoff has been proven.
Serious illness during early pregnancy can affect fetal development in general. For Developmental and epileptic encephalopathy 87, these effects have not been confirmed as a specific cause, but doctors still review them when assessing possible risk.
High-dose radiation and toxic exposures such as heavy metals can disrupt early development. No environmental exposure has been proven to directly cause Developmental and epileptic encephalopathy 87, but these are part of the broader factors doctors consider.
Premature birth, severe lack of oxygen, or major complications around delivery can affect brain development. These are not established causes of Developmental and epileptic encephalopathy 87 itself, though they can overlap with the signs that lead to further testing.
Genetic risk factors
For families facing seizures and developmental delays, the answer often lies in genetics. Developmental and epileptic encephalopathy 87 is usually linked to a rare disease-causing variant that affects how the brain develops and how nerve cells communicate. Carrying a genetic change doesn’t guarantee the condition will appear. Many families have no prior history because the variant can begin for the first time in the child.
Rare gene variant: Developmental and epileptic encephalopathy 87 is most often linked to a rare harmful change in a single gene that is important for brain signaling and development. This is the main genetic cause identified in affected families.
New variant: In many children, the gene change happens for the first time in them and is not inherited from either parent. This is why early symptoms of Developmental and epileptic encephalopathy 87 can appear even when no one else in the family is affected.
Inherited change: Some families do pass the disease-causing variant from parent to child. When that happens, the chance of recurrence depends on the exact inheritance pattern of that specific genetic finding.
Parental mosaicism: Sometimes a parent carries the variant in only some of their cells, which is called mosaicism. This can increase the chance of another affected child even if the parent has few or no symptoms and routine blood testing is normal.
Family history: A known family history of the same disease-causing variant can raise the chance that close relatives may also carry it. Even within one family, the severity and seizure pattern can vary a lot.
Lifestyle risk factors
Developmental and epileptic encephalopathy 87 is not caused by lifestyle habits, but daily routines can still influence seizure control, safety, and overall function. When families ask how lifestyle affects Developmental and epileptic encephalopathy 87, the most important issues are factors that lower the seizure threshold or make complications harder to manage. Practical habits are mainly used to reduce triggers, support nutrition and development, and improve day-to-day stability.
Poor or irregular sleep can make seizures more likely in many epileptic encephalopathies, including Developmental and epileptic encephalopathy 87. A consistent sleep schedule and good nighttime routines may help reduce seizure provocation and daytime irritability.
Missed, late, or inconsistent antiseizure medicine doses can quickly worsen seizure control in Developmental and epileptic encephalopathy 87. Using reminders, measured dosing tools, and a reliable routine can help prevent breakthrough seizures.
Fever, dehydration, and poor fluid intake can stress the body and lower the seizure threshold. Prompt hydration and careful sick-day management may help limit seizure worsening and reduce the chance of emergency complications.
Feeding difficulties, low calorie intake, or long gaps between meals can worsen weakness, recovery, and overall resilience in a child with Developmental and epileptic encephalopathy 87. Nutrition plans that fit swallowing ability and energy needs can support growth and may make illness-related setbacks less severe.
Risk prevention
For families affected by Developmental and epileptic encephalopathy 87, true prevention of the condition itself is usually not possible because it is a genetic condition present from the start. Prevention is about lowering risk, not eliminating it completely. In daily life, the focus is on reducing seizure triggers, catching problems early, and supporting development, sleep, and overall health.
Regular care with a neurologist and pediatric team can help keep seizures under better control and lower the risk of complications. Visits also help adjust treatment as a child grows and as symptoms of Developmental and epileptic encephalopathy 87 change over time.
Anti-seizure medicines work best when doses are taken exactly as prescribed and not stopped suddenly. Missing doses can raise the chance of breakthrough seizures or even a seizure emergency.
For many living with Developmental and epileptic encephalopathy 87, poor sleep, illness, fever, flashing lights, or missed meals may trigger seizures. Keeping a simple routine and noting patterns in a seizure diary can help families spot preventable triggers.
A steady sleep schedule can lower seizure risk and often helps daytime behavior and attention as well. Prevention works best when it becomes part of daily life, not a special project.
Can you prevent Developmental and epileptic encephalopathy 87?
No, developmental and epileptic encephalopathy 87 usually cannot be prevented, because it is most often caused by a change in a gene that affects brain development and seizure activity. Nothing a parent did before or during pregnancy is known to cause it in most cases. If this condition runs in a family or a gene change has already been found, genetic counseling and family testing may help people understand the chance of it happening again in a future pregnancy.
Transmission
Developmental and epileptic encephalopathy 87 is not infectious, so it cannot be caught from someone else through close contact, coughing, kissing, sex, or sharing food. For many living with Developmental and epileptic encephalopathy 87, the condition is related to a change in a gene that affects brain development and seizures.
The genetic transmission of Developmental and epileptic encephalopathy 87 can vary depending on the exact gene change. In some families the change happens for the first time in the child, while in others it may be passed down from a parent, so genetic testing is often the best way to clarify future pregnancy risk.
When to test your genes
Consider genetic testing early if a baby or child has unexplained seizures, especially when they begin in infancy and come with developmental delay, low muscle tone, or movement differences. For many living with developmental and epileptic encephalopathy 87, testing can confirm the cause, guide care, and clarify family recurrence risk.
Diagnosis
Developmental and epileptic encephalopathy 87 is usually diagnosed when a child has seizures along with developmental delays or a loss of skills, and the pattern does not fit a more common cause. The diagnosis often starts with careful review of symptoms and exam findings, then is confirmed with tests that look at brain activity and the underlying gene change. Getting a diagnosis is often a turning point toward answers and support.
Doctors look closely at when seizures began, how they appear, and whether development has been delayed or skills have changed over time. A detailed family and health history can help show whether there may be a genetic cause and guide the next tests.
The care team checks muscle tone, reflexes, movement, alertness, and developmental progress. These clinical features can support the diagnosis of Developmental and epileptic encephalopathy 87, although they are not enough on their own to confirm it.
An electroencephalogram, or EEG, records the brain’s electrical activity and helps show seizure patterns or ongoing abnormal activity between seizures. This is often a key part of the genetic diagnosis of Developmental and epileptic encephalopathy 87 because it helps define the epilepsy syndrome.
Brain imaging is often done to look for structural causes of seizures or developmental problems. MRI findings may be normal in some children, but the scan is still useful because it helps rule out other conditions.
How is Developmental and epileptic encephalopathy 87 diagnosed?
Doctors usually suspect developmental and epileptic encephalopathy 87 when a child has seizures along with delayed development or loss of skills, and they often use a brain wave test called an EEG plus a brain scan such as MRI to look for a pattern and rule out other causes. A genetic test is usually used to look for the specific gene change linked to this condition and help confirm the diagnosis, along with a review of symptoms, medical history, and the child’s exam.
Stages of Developmental and epileptic encephalopathy 87
Developmental and epileptic encephalopathy 87 does not have defined progression stages. This is because it is usually described by a pattern of early-onset seizures and developmental difficulties rather than by clear step-by-step phases that everyone moves through over time. Often the process begins when you notice changes in daily life, and doctors usually diagnose developmental and epileptic encephalopathy 87 by looking at the seizure pattern, development, brain wave testing such as an EEG, brain imaging, and genetic testing to confirm the cause. The early symptoms of developmental and epileptic encephalopathy 87 can vary from one child to another, so follow-up focuses on seizure control, development, and how the condition is affecting day-to-day life.
Outlook and prognosis
The outlook for people with developmental and epileptic encephalopathy 87 is generally guarded, with most affected individuals having persistent developmental impairment and ongoing neurologic disability. Seizures often begin early and can be difficult to control, although some patients may have partial improvement with anti-seizure treatment or changes in seizure pattern over time. Intellectual disability, speech limitations, motor difficulties, and behavioral or autistic features commonly continue into childhood and adulthood, so long-term supportive care is usually needed. Because this is a very rare disorder, precise life-expectancy data are not available, but mortality can be higher than in the general population when seizures are severe or when complications such as status epilepticus, aspiration, respiratory infections, or sudden unexpected death in epilepsy occur. Prognosis varies from person to person and depends largely on seizure burden, response to treatment, and the severity of associated developmental and medical complications.
Long-term effects
Developmental and epileptic encephalopathy 87 can affect learning, movement, communication, and day-to-day independence over many years. The long-term picture is often shaped by how early brain development is affected and by how well seizures are controlled, although experiences vary from one person to another. Many living with Developmental and epileptic encephalopathy 87 have lifelong support needs, while some features become clearer as a child grows.
Ongoing delays in thinking, learning, and problem-solving are common in Developmental and epileptic encephalopathy 87. Some children have severe intellectual disability, and these differences often continue into adult life.
Many people with Developmental and epileptic encephalopathy 87 have limited speech or may not develop spoken language. Communication challenges can affect school, relationships, and everyday needs, even when understanding is better than speech.
Seizures may continue over the long term, though their type and frequency can change with age. In some families, the early symptoms of Developmental and epileptic encephalopathy 87 are seizures in infancy or early childhood, and ongoing epilepsy can add to learning and safety concerns.
Low muscle tone, stiffness, poor balance, or an unsteady walk can affect mobility over time. Some may find sitting, standing, or walking independently harder as physical demands increase with growth.
How is it to live with Developmental and epileptic encephalopathy 87?
Living with developmental and epileptic encephalopathy 87 often means living with both hard-to-control seizures and major developmental challenges, so daily life may revolve around medications, therapy visits, close supervision, and adapting routines around safety, sleep, feeding, communication, and learning. Many people with this condition need substantial support, and while the picture can vary, families and other caregivers are often deeply affected too, balancing medical care, emergency planning, and the emotional strain that comes with uncertainty. Even so, with coordinated care and practical supports, many families find ways to build routines, celebrate progress, and create a life that is shaped by the condition but not defined only by it.
Treatment and drugs
Treatment for Developmental and epileptic encephalopathy 87 focuses on controlling seizures, supporting development, and managing daily challenges such as feeding, sleep, movement, or learning problems. Because this condition is rare and often starts early in life, care usually involves a neurologist and other specialists, and treatment may include anti-seizure medicines, nutrition support, physical or speech therapy, and help with breathing or swallowing if needed. Not every treatment works the same way for every person, so doctors often adjust medicines over time based on seizure control, side effects, and how a child is growing and developing. For families looking into treatment options for Developmental and epileptic encephalopathy 87, it helps to know that care is usually aimed at symptom control and quality of life rather than a cure. Support from family or friends can make daily treatment easier, especially when routines include medicines, therapy visits, and close follow-up.
Can you cure Developmental and epileptic encephalopathy 87?
No, there is currently no cure for developmental and epileptic encephalopathy 87. Treatment aims to control seizures as much as possible, support development and daily functioning, and help with related problems such as feeding, movement, or sleep, but it cannot reverse the underlying genetic change. Care is usually tailored to the individual because symptoms and day-to-day needs can vary.
Non-drug treatment
Daily care for Developmental and epileptic encephalopathy 87 often involves more than seizure medicine alone. Many living with this condition need therapies that support movement, communication, learning, feeding, sleep, and safety at home and school. Because symptoms can vary a lot, the best non-drug plan is usually tailored to the child and adjusted over time. Not every approach works the same way, so families often build a mix of supports around the child’s main needs.
Early intervention and structured developmental therapy can help build skills in play, movement, communication, and daily routines. For many, treatment begins not at the pharmacy, but with steady practice woven into everyday life.
Physical therapy can improve balance, posture, strength, and mobility in children who are stiff, unsteady, or delayed in motor milestones. This can make day-to-day tasks like sitting, walking, or getting in and out of a chair safer and easier.
Occupational therapy helps with hand use, sensory challenges, dressing, feeding, and other daily activities. Some may find it also supports attention and comfort during school or home routines.
Speech and language therapy can help with understanding, making sounds, and using nonverbal ways to communicate. If spoken language is limited, tools such as picture boards or communication devices may help reduce frustration.
Your genes may have an impact on how drugs work for you
For people living with developmental and epileptic encephalopathy 87, the underlying genetic change may affect how well some seizure medicines work and, in some cases, whether a medicine could make seizures or side effects worse. In day-to-day life, this can mean one child improves on a treatment while another with a different genetic cause may need a different plan, even if their seizures look similar at first. Because of that, genetic test results can sometimes help the care team choose medicines more carefully, but treatment still often comes down to watching closely and adjusting based on how the person responds.
Pharmacological treatments
Living with Developmental and epileptic encephalopathy 87 often means treatment is centered on seizure control, because there is no single medicine that corrects the underlying genetic change. Doctors usually choose anti-seizure medicines based on seizure type, age, side effects, and how a child has responded before. In some people with Developmental and epileptic encephalopathy 87, medicines that calm overactive sodium channels seem especially helpful. Not everyone responds to the same medication in the same way.
Phenytoin is one of the medicines most often reported to help seizures in Developmental and epileptic encephalopathy 87. It may be used regularly or in urgent situations when seizures are prolonged.
Carbamazepine and oxcarbazepine are sodium channel medicines that may reduce seizures in some people with Developmental and epileptic encephalopathy 87. Doctors use them carefully, since seizure patterns and benefit can vary from one child to another.
Lamotrigine is another sodium channel medicine that may help some children with Developmental and epileptic encephalopathy 87. Because it must be increased slowly, it is usually started with close follow-up.
Valproate and levetiracetam are broad-spectrum anti-seizure medicines that may be tried when doctors are treating the early symptoms of Developmental and epileptic encephalopathy 87 or adjusting a long-term plan. If one option isn’t effective, second-line or alternative drugs may be offered.
Genetic influences
When seizures start in infancy and development does not follow the usual path, families often ask if there is a genetic reason. Developmental and epileptic encephalopathy 87 is a genetically defined form most often caused by a harmful change in the CDK19 gene. It usually follows an autosomal dominant pattern, although many reported cases happen because the gene change is new in the child and was not inherited from either parent. To put these pieces together, doctors may suggest genetic counseling, along with genetic testing for Developmental and epileptic encephalopathy 87, to confirm the diagnosis and discuss family risk. If the change is new, the chance of it happening again is usually low, but it can be higher if a parent carries the change or has mosaicism, meaning the variant is present in only some of their cells.
Is Developmental and epileptic encephalopathy 87 genetic?
Genetics are central to Developmental and epileptic encephalopathy 87, which is caused by harmful changes in the HECW2 gene. These genetic variations usually arise new in the child, though rarely they can be inherited.
Having a genetic risk is not necessarily a diagnosis
Changes in genes, often called genetic variants, are a normal part of human biology and are common throughout the general population. Most do not directly affect health and simply reflect natural human diversity. For many genes, having a variant associated with a condition suggests a possible link rather than a certain diagnosis, especially when several genes and environmental factors are involved. In some situations, though, one well-understood variant in a particular gene can be enough to confirm a diagnosis.
Pharmacogenetics—how genetics influence drug effects
When seizures are hard to control and medicines seem to help one week but not the next, families often want to know whether the genetic cause can guide treatment. In Developmental and epileptic encephalopathy 87, the exact gene change can sometimes help doctors choose the most sensible anti-seizure medicines and avoid options that are less likely to help. Genes can influence how quickly you process medicine, but for Developmental and epileptic encephalopathy 87 the bigger issue is often how the changed gene affects nerve cell signaling and seizure patterns. That is why genetic testing for Developmental and epileptic encephalopathy 87 may do more than confirm a diagnosis; it can sometimes shape treatment decisions, including whether to consider a more targeted therapy or a clinical trial. Still, there is rarely one guaranteed best medication, and many living with this condition need treatment changes over time. Age, other health conditions, and other medicines also matter, so care is usually most effective when epilepsy and genetics specialists look at the whole picture.
Interactions with other conditions
People living with developmental and epileptic encephalopathy 87 often have complex needs, so other health problems can have a bigger effect on daily life than they would otherwise. Seizures, developmental delays, low muscle tone, feeding problems, sleep difficulties, and movement issues can overlap, and an illness such as a fever, stomach bug, or chest infection may make seizures or recovery harder. Some may also have trouble swallowing or poor airway protection, which can raise the risk of aspiration and lung infections. Developmental and epileptic encephalopathy 87 can also occur alongside autism traits, attention and behavior differences, or vision and hearing problems, which may affect learning, communication, and safety. Interactions can look very different from person to person. Because early symptoms of developmental and epileptic encephalopathy 87 can change over time, doctors usually watch the whole picture closely and adjust care when another condition, medicine, or stress on the body seems to worsen symptoms.
How genes can cause diseases
Humans have more than 20,000 genes, each carrying out one or a few specific functions in the body. One gene instructs the body to digest lactose from milk, another tells the body how to build strong bones and another prevents the body's cells from beginning to multiply uncontrollably and developing into cancer. As all of these genes combined are the building instructions for our body, a defect in one of these genes can have severe health consequences.
Through decades of genetic research, we know the genetic code of any healthy/functional human gene. We have also identified that in certain positions on a gene, some individuals may have a different genetic letter from the one you have. We call these hotspots "Genetic Variations" or "Variants" in short. In many cases, studies have been able to show that having the genetic letter "G" in the position makes you healthy, but having the letter "A" in the same position disrupts the gene function and causes a disease. Genopedia allows you to view these variants in genes and summarizes all that we know from scientific research, which genetic letters (Genotype) have good or bad consequences on your health or on your traits.
What other conditions can cause similar symptoms to Developmental and epileptic encephalopathy 87?
Other conditions that can look similar include other severe seizure disorders that begin in infancy or childhood, such as Dravet syndrome, Lennox-Gastaut syndrome, and infantile spasms, as well as other rare genetic conditions that affect brain development. In some children, problems linked to a lack of oxygen around birth, brain structure differences, or certain body-chemistry disorders can also cause both seizures and developmental delay, so doctors often need brain wave tests, brain scans, and genetic testing to tell them apart.
History
For many living with developmental and epileptic encephalopathy 87, the name may only come after a long stretch of unanswered questions, changing symptoms, and many specialist visits. This condition entered medical understanding gradually, as doctors learned to connect early seizures, developmental differences, and changes seen over time rather than viewing each problem on its own.
Initially understood only through symptoms, later research helped show that developmental and epileptic encephalopathy 87 belongs to a broader group of severe epilepsy-related brain disorders that begin early in life. In the past, children with similar patterns of seizures and delayed development were often described under wider labels, because the tools to separate one rare condition from another were limited. As brain imaging, EEG testing, and genetic testing improved, doctors became better able to recognize when a child’s symptoms fit a more specific diagnosis.
That shift mattered in everyday life. Instead of hearing only that a child had “epilepsy” or “developmental delay,” families could begin to get a clearer explanation for why both were happening together. In recent years, researchers have identified a genetic cause for developmental and epileptic encephalopathy 87, which helped confirm that it is a distinct condition rather than just a variation of another epilepsy syndrome. This has also improved the way specialists talk about the early symptoms of developmental and epileptic encephalopathy 87 and what kinds of follow-up may be helpful.
Even so, much of what is known about developmental and epileptic encephalopathy 87 is still fairly new. Because it is rare, many of the first published reports involved only small numbers of children, and the picture has expanded as more families have been diagnosed. Today, the history of developmental and epileptic encephalopathy 87 is still being written, with each new case helping doctors better understand how symptoms can differ from one person to another and how to support people living with the condition more effectively.
