Role of Vitamin D in schizophrenia in elderly patient

Vitamin D deficiency is common in the patient with mental illness such as schizophrenia; several environmental risk factors for schizophrenia, such as season of birth, latitude, and migration, have been linked to Vitamin D deficiency. Recent studies have suggested a potential role of Vitamin D in the development of schizophrenia, for example, neonatal Vitamin D status is associated with the risk of developing schizophrenia in later life. Here, we report a case of Vitamin D deficiency presenting with schizophrenia. Vitamin D supplementation is promising treatment strategy to prevent relapse to improve psychotic symptoms, and physical health in patients with schizophrenia should be further explored in future studies.
