Root Causes

Etiology // Origins

Root Causes & Triggers

Brain Structure Anomalies

Differences in the frontal cortex and subcortical structures of the brain that affect the ability to filter thoughts.

Genetics

A strong hereditary component; having a first-degree relative with OCD increases the risk.

Learned Behaviors

Compulsions are learned over time because they temporarily relieve the intense anxiety of an obsession.

Islamic Perspective

"Obsessive thoughts (Waswasah) are a sickness of the mind, not a reflection of weak faith."

Abu Zayd al-Balkhi(9th Century (850–934 CE))

Reflection & Clinical Context

Al-Balkhi explicitly normalized obsessive thoughts, telling patients they were not sinful for having them. He recommended active cognitive distraction and ignoring the urge to perform compulsions, pre-dating modern Exposure and Response Prevention (ERP) therapy by a millennium.
