Butwicka et al7 reported on a total of 44 adolescents, 43 late-onset adults, and 45 early-onset adults with OCD; adolescents showed more religious, sexual, and miscellaneous obsessions than late-onset adults; contamination obsessions were seldom found in adolescents,

and cleaning Dipeptidyl peptidase compulsions were more frequent in early-onset adults than in adolescents. Checking compulsion was the rarest in the younger age group. In an article on clinical features in children, Vera et al8 pointed out that young children with OCD often heard an inner voice ordering ritualizations, were often doubtful on trivial matters, indecisive, exhibited an unusal slowness in everyday activities, and felt greatly relieved upon completion of compulsions.
