C – Childhood trauma, especially physical or emotional abuse, raises the likelihood.

D – Delicate dopamine balance disruption may contribute to susceptibility.

I – Infections, particularly Group A Streptococcal infections, are linked to the onset.

S – Stressful life events, especially those related to contamination fears, can trigger OCD.

K – Knowledge of a personal or family history of tic disorders increases risk.

F – Frontal lobe dysfunction, seen in neuroimaging studies, is associated with higher risk.

A – Autoimmune disorders, such as rheumatic fever, are potential risk factors.

C – Cortico-striato-thalamo-cortical (CSTC) circuit abnormalities play a role in susceptibility.

T – Tryptophan deficiency may contribute to the development of OCD.

O – Obsessive thoughts during pregnancy, especially related to harm fears, can increase risk.
