Separation Anxiety Disorder in Panic Disorder Patients with and without Comorbid Agoraphobia.

: Previous studies have focused on the relationship between childhood separation anxiety disorder (SAD) and adult panic disorder (PD)-agoraphobia. It is not clear enough whether SAD, which continues into adulthood, is associated with PD with and without comorbid agoraphobia in adult patients. Our primary hypothesis was that PD patients with comorbid agoraphobia had a higher rate of SAD that continues into adulthood than those without agoraphobia.

The subthreshold autistic traits in patients with adult-onset obsessive-compulsive disorder: a comparative study with adolescent patients.

Objective: The primary objective of this study was to compare the adult-onset and adolescent obsessive-compulsive disorder (OCD) patients in terms of the subthreshold autistic traits.

Methods: 29 adolescent, and 45 adult-onset OCD patients were assessed by Autism-spectrum Quotient (AQ).

Results: The ratio of males to females, the frequency of ritualistic compulsions, and the mean number of lifetime compulsions were significantly higher in adolescents with OCD compared to adult-onset patients.
