Soft Neurological Signs and Cognitive Function in Obsessive-compulsive Disorder Patients

Area of Science:

• Neuroscience
• Psychiatry
• Clinical Psychology

Background:

• Historically, psychoanalytical theories dominated obsessive-compulsive disorder (OCD) research.
• Modern research increasingly points to biological underpinnings of OCD.

Purpose of the Study:

• To investigate neurobiological markers, specifically soft neurological signs (NSS) and cognitive functions, in individuals with OCD.
• To explore the role of these biological factors in the development of OCD.

Main Methods:

• A cross-sectional study was conducted with 50 OCD patients and age/education-matched controls.
• Neurological soft signs (NSS) and cognitive deficits were assessed using established instruments.

Main Results:

• OCD patients exhibited significantly more NSS across various domains, including motor coordination, sensory integration, and spatial orientation.
• Cognitive deficits were more pronounced in OCD patients in areas such as visuospatial ability, executive function, attention, and working memory.

Conclusions:

• The study underscores the significant role of biological factors, including soft neurological signs and cognitive dysfunction, in the etiology of OCD.
• These findings support a neurobiological model for understanding obsessive-compulsive disorder.
