Risk Factors and Prognosis of Autism Spectrum Disorder
Risk Factors and Prognosis of Autism Spectrum Disorder in Children Attending Assiut University Children's Hospital
調査の概要
状態
詳細な説明
Autism spectrum disorder is a neurodevelopmental condition with multifactorial etiology involving genetic and environmental factors. This observational case-control study will include children aged 3 to 17 years diagnosed with ASD according to DSM-5 criteria and age- and sex-matched controls without neurodevelopmental disorders.
Risk factors (antenatal, perinatal, and postnatal) will be compared between cases and controls. Children with ASD will be followed for 6 months to assess changes in symptom severity and adaptive functioning.

Prevalence of risk factors in ASD versus controls
時間枠:Baseline
|
Proportion of children with specific antenatal, perinatal, and postnatal risk factors (advanced parental age, consanguinity, maternal infection, gestational diabetes, birth asphyxia, NICU admission, and family history of ASD) among ASD cases compared with age- and sex-matched controls.

Response to early intervention
時間枠:At 6 months
|
Proportion of children with ASD showing clinical improvement after speech, occupational, and behavioral therapy.
|
At 6 months

|
Development of comorbidities
時間枠:Through 6 months
|
Proportion of children with ASD who develop associated comorbidities (seizures, gastrointestinal problems, sleep disturbances) during follow-up.
|
Through 6 months

|
Change in Childhood Autism Rating Scale score
時間枠:From baseline to 6 months
|
Change in Childhood Autism Rating Scale (CARS) total score from baseline to 6 months in children with ASD.
CARS ranges from 15 to 60; higher scores indicate greater autism severity.
|
From baseline to 6 months
|
|
Change in Vineland Adaptive Behavior Scales score
時間枠:From baseline to 6 months
|
Change in Vineland Adaptive Behavior Scales composite score from baseline to 6 months in children with ASD.
Higher scores indicate better adaptive functioning.
