Affected individuals may have (a) developmental and epileptic encephalopathy (DEE) (i.e., intractable seizures with developmental delays associated with ongoing epileptiform EEG activity) with or without malformations of cortical development; or (b) malformations of cortical development with or without mild focal epilepsy. Some degree of early childhood developmental delay is seen in all affected individuals; the severity varies widely, ranging from isolated speech delay to severe developmental delay. Infantile hypotonia is common but may be mild or absent in those without DEE. In those with DEE, seizure onset is typically in the first six to 12 months of life. A variety of seizure types have been described. Seizures remain intractable to multiple anti-seizure medications in approximately 50% of individuals with DEE without malformations of cortical development (MCD) and in 90% of individuals with DEE and MCD. Seizures may be absent or infrequent in those without DEE. Brain MRI findings range from normal to showing thinning or hypoplasia of the corpus callosum, to various malformations of cortical development. Autonomic dysregulation, oromotor dysfunction leading to the need for gastrostomy tube placement, progressive microcephaly, hyperkinetic movement disorder, and cortical visual impairment can also be seen in those with DEE." /><meta name="robots" content="index,nofollow,noarchive" />

<div class="portlet_content ln"><div class="excerpt">Excerpted from the <i>GeneReview: </i><a href="/books/NBK570882" target="_blank">SCN3A-Related Neurodevelopmental Disorder</a></div><div>SCN3A-related neurodevelopmental disorder (SCN3A-ND) encompasses a spectrum of clinical severity associated with epilepsy and/or brain malformation. Affected individuals may have (a) developmental and epileptic encephalopathy (DEE) (i.e., intractable seizures with developmental delays associated with ongoing epileptiform EEG activity) with or without malformations of cortical development; or (b) malformations of cortical development with or without mild focal epilepsy. Some degree of early childhood developmental delay is seen in all affected individuals; the severity varies widely, ranging from isolated speech delay to severe developmental delay. Infantile hypotonia is common but may be mild or absent in those without DEE. In those with DEE, seizure onset is typically in the first six to 12 months of life. A variety of seizure types have been described. Seizures remain intractable to multiple anti-seizure medications in approximately 50% of individuals with DEE without malformations of cortical development (MCD) and in 90% of individuals with DEE and MCD. Seizures may be absent or infrequent in those without DEE. Brain MRI findings range from normal to showing thinning or hypoplasia of the corpus callosum, to various malformations of cortical development. Autonomic dysregulation, oromotor dysfunction leading to the need for gastrostomy tube placement, progressive microcephaly, hyperkinetic movement disorder, and cortical visual impairment can also be seen in those with DEE. [from <a title="GeneReviews" href="https://www.ncbi.nlm.nih.gov/books/NBK1116" class="defSource" target="_blank">GeneReviews</a>]</div><div class="spaceAbove"><strong>Full text of <i>GeneReview</i> (by section):</strong><br /><a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Summary" target="NBK570882">Summary</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Diagnosis" target="NBK570882">Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Clinical_Characteristics" target="NBK570882">Clinical Characteristics</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Genetically_Related_Allelic_Di" target="NBK570882">Genetically Related (Allelic) Disorders</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Differential_Diagnosis" target="NBK570882">Differential Diagnosis</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Management" target="NBK570882">Management</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Genetic_Counseling" target="NBK570882">Genetic Counseling</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Resources" target="NBK570882">Resources</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Molecular_Genetics" target="NBK570882">Molecular Genetics</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.Chapter_Notes" target="NBK570882">Chapter Notes</a>  |  <a class="medgenPMinfo" href="/books/NBK570882#scn3a-ndd.References" target="NBK570882">References</a></div><div class="spaceAbove"><strong>Authors:</strong><br />

<div class="spaceAbove">Attention-deficit/hyperactivity disorder (ADHD) is a behavioral disorder that typically begins in childhood and is characterized by a short attention span (inattention), an inability to be calm and stay still (hyperactivity), and poor impulse control (impulsivity). Some people with ADHD have problems with only inattention or with hyperactivity and impulsivity, but most have problems related to all three features.\n\nIn people with ADHD, the characteristic behaviors are frequent and severe enough to interfere with the activities of daily living such as school, work, and relationships with others. Because of an inability to stay focused on tasks, people with inattention may be easily distracted, forgetful, avoid tasks that require sustained attention, have difficulty organizing tasks, or frequently lose items.\n\nHyperactivity is usually shown by frequent movement. Individuals with this feature often fidget or tap their foot when seated, leave their seat when it is inappropriate to do so (such as in the classroom), or talk a lot and interrupt others.\n\nImpulsivity can result in hasty actions without thought for the consequences. Individuals with poor impulse control may have difficulty waiting for their turn, deferring to others, or considering their actions before acting.\n\nMore than two-thirds of all individuals with ADHD have additional conditions, including insomnia, mood or anxiety disorders, learning disorders, or substance use disorders. Affected individuals may also have autism spectrum disorder, which is characterized by impaired communication and social interaction, or Tourette syndrome, which is a disorder characterized by repetitive and involuntary movements or noises called tics.\n\nIn most affected individuals, ADHD continues throughout life, but in about one-third of individuals, signs and symptoms of ADHD go away by adulthood.</div>

<div class="spaceAbove">Hypotonia is an abnormally low muscle tone (the amount of tension or resistance to movement in a muscle). Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.</div>
