[Autism Spectrum Disorders (ASD) and Obsessive Compulsive Disorder (OCD): a new approach from the DSM-5-TR and its...

Area of Science:

• Neurodevelopmental Disorders
• Psychiatric Disorders

Background:

• Autism Spectrum Disorder (ASD) and Obsessive Compulsive Disorder (OCD) share overlapping symptoms, leading to diagnostic challenges.
• Comorbidity of ASD and OCD can result in a more severe clinical presentation.
• Individuals with co-occurring ASD and OCD often exhibit a diminished response to standard OCD treatments.

Purpose of the Study:

• To review the current understanding of ASD and OCD.
• To delineate the specific characteristics of both ASD and OCD.
• To examine the implications of DSM-5-TR updates on the diagnosis and treatment of these conditions.
• To outline current evaluation and treatment approaches for ASD-OCD comorbidity.

Main Methods:

• Literature review of current research on ASD and OCD.
• Analysis of diagnostic criteria and recent updates (DSM-5-TR).
• Synthesis of information on clinical presentation, evaluation, and treatment strategies.

Main Results:

• Diagnostic confusion and symptom overlap between ASD and OCD are significant.
• The comorbidity of ASD-OCD presents unique clinical features.
• DSM-5-TR revisions may impact the classification and understanding of these disorders.
• Current treatment approaches for OCD may be less effective in the presence of ASD.

Conclusions:

• The co-occurrence of ASD and OCD (ASD-OCD comorbidity) is characterized by distinct atypicalities.
• A thorough and individualized evaluation is crucial for accurate diagnosis.
• Treatment strategies must be adapted to address the specific needs of individuals with ASD-OCD comorbidity.
