Early recognition of obsessive-compulsive disorder

Area of Science:

• Psychiatry
• Neuroscience
• Clinical Psychology

Background:

• The early clinical and neurobiological course of obsessive-compulsive disorder (OCD) is largely unknown.
• OCD often begins in childhood or adolescence, but preceding behavioral changes and symptoms have not been well-assessed.
• Understanding the prodrome of OCD is crucial for early intervention and improved patient outcomes.

Purpose of the Study:

• To investigate the nature of the earliest behavioral changes and symptoms preceding the onset of obsessive-compulsive disorder (OCD).
• To explore the relationship between these initial symptoms and later OCD severity and depressive comorbidity.

Main Methods:

• A retrospective study involving 40 adult patients diagnosed with OCD.
• Patients completed a self-developed questionnaire assessing early life changes and symptoms before the age of 20.
• Severity of OCD was measured using the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), and depression was assessed with the Hamilton Depression Rating Scale.

Main Results:

• Twenty-three patients reported initial changes before age 20.
• Commonly reported early symptoms included anxiety and lack of self-trust, while more specific OCD symptoms like a heightened sense of responsibility or need for order were less recalled.
• No significant relationship was found between early changes and later Y-BOCS scores, but a correlation with depressive comorbidity was observed.

Conclusions:

• Obsessive-compulsive disorder may present with a prodrome characterized by unspecific, often depressive, symptoms, similar to other psychiatric disorders.
• These preliminary findings suggest a potentially less specific early psychopathology in OCD.
• Further prospective studies with larger samples are needed to validate these retrospective findings.
