Individuals with epilepsy are at increased risk of symptoms
of the Autism Spectrum Disorder (ASD), especially if the epilepsy appears in
childhood. Among individuals with epilepsy in a recent study, 1.6% of them compared
with 0.2% of controls were diagnosed with ASD. Individuals with epilepsy were
therefore at increased risk of future ASD. Further, ASD is more common in the
siblings and offspring of individuals who have epilepsy, suggesting a shared cause.
The risk in the offspring was particularly high in mothers with epilepsy.
Epilepsy was also associated with a prior diagnosis of ASD. 1
Autism is a neurodevelopmental disorder. The Autism
spectrum is wide-ranging. It varies from severe to very high functioning
behavior. The spectrum comprises Asperger’s syndrome—which is on the higher-functioning end of the autism
spectrum―to childhood
disintegrative disorder and the pervasive developmental disorder. Autism
Spectrum Disorder affects the child’s development and learning. It is generally
suspected by behavioral variances as compared with their peers around age
three.
Symptoms of ASD include difficulty with social
interaction, impaired verbal and nonverbal communication and repetitive
behaviors, such as rocking, pacing and repeating actions and words. The
spectrum is characterized by hypersensitivity to external stimulations, such as
noise and being touched. A common clue of this in young children can be folding
down their ears in an attempt to block-out noises.
Some form of autism affects one out of every 68 kids and
it affects more boys than girls. The number of children diagnosed with autism
spectrum disorder is rising, but it is not clear whether the increased
frequency is due to better detection and reporting of the disorder or due to a
real increase in the number of cases, or both.
