Correct Answer � A
Explanation
|
|
Diagnosis of Autism Spectrum Disorder (ASD):
-
- ASD is a neurodevelopmental disorder diagnosed clinically based on behavioral observations and developmental history, primarily using the DSM-5 criteria:
- Persistent deficits in social communication and social interaction.
- Restricted, repetitive patterns of behavior, interests, or activities.
Why Other Options Are Incorrect:
-
- Genetic studies (B, D): Although certain genetic syndromes (e.g., Fragile X syndrome) are associated with ASD, genetic testing is not required for diagnosis.
- MRI brain (C, D): Neuroimaging is not routinely used for diagnosis but may be performed to rule out other structural brain abnormalities.
