title: Vitamin D insufficiency in a boy with obsessive-compulsive disorder.
abstract: Vitamin D deficiency not only causes low bone mass but also may lead to neuropsychiatric disorders. In the present case, vitamin D supplementation reduced obsessive-compulsive disorder (OCD) symptoms associated with streptococcal infection in a 7-year-old boy. Sudden onset of symptoms, including excessive hand washing and fear of touching anything, had occurred 1 month before presentation. Although there are few studies on a possible causal relationship between vitamin D and neuropsychiatric disorders, the present report; together with previous data, suggest an etiological role of vitamin D-related immune processes.
