Summary

This case report details a family with a three-generation history of counting coercion, a symptom of obsessive-compulsive disorder (OCD). Further research is needed to determine if counting is a distinct OCD subtype or if genetic vulnerability is inherited.

Area of Science:

Psychiatry
Genetics
Neurobiology

Background:

Obsessive-compulsive disorder (OCD) affects 2-3.5% of the population.
Identifying homogenous familial characteristics can define OCD subtypes.
