Obsessive-compulsive disorder (OCD) is a mental health condition that can significantly impact the lives of both adults and children. According to recent research, OCD affects approximately 1% to 3% of children and adolescents worldwide ( Zalpuri et al., 2025 ). Pediatric OCD often goes undiagnosed for years, delaying access to evidence-based care and support. There are known to be two primary peaks of onset: the first in late childhood (mean age 9-10, pre-pubertal) and a second in the early twenties, highlighting the importance of recognizing and addressing symptoms early.
