Hello,
As per my clinical experience, your relevant information is pertaining to different sets of clinical conditions, which need to be explained separately.
@
Autism spectrum disorder:
- Characterised by difficulty in social interactions, behavior, language, intellectual behavior which impair daily functioning
- Usually children are yonger than 3 years age
- High incidences of abnormal EEG, seziures and abnormal brain morphology
- About 25% of them develop seizures by adulthood
- It is not genetically transmitted which goes for differential diagnosis of Rett disease (X linked) in girls with mental retardation and microcephaly
@ Attention deficit hyperactivity disorder:
- Inattentive (predominant type A)
Hyperactive or impulsive (predominant type B) or mix of A and B type
- The symptoms occur in both set up as school, home or work.
- More common in boys
- Must be present for more than 6 months duration
- Increase risk of development disorders in adolescence
The diagnosis of both is clinical and there are no absolute diagnostic tests but cognitive evaluation do help to assess the severity of the condition.
Take care. Hope I have answered your question. Let me know if I can assist you further.
