Here is a quick mnemonic/memory aid “OCD RISK FACTOR“ to remember about the Differential Diagnosis of Obsessive-Compulsive Disorder
O – OCPD (Obsessive-Compulsive Personality Disorder) comorbidity increases risk.
C – Childhood trauma, especially physical or emotional abuse, raises the likelihood.
D – Delicate dopamine balance disruption may contribute to susceptibility.
R – Relatives with OCD elevate the risk significantly.
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.
R – Repetitive behaviors in childhood may be an early sign of vulnerability.
