Abstract
Fahr’s disease is a rare neurological disorder that is characterized by
bilateral basal ganglia calcification. In the present study, a 49-year-old
male patient presented with delusional beliefs. He had normal neurologic
examination. Follow-up mental status examination and clinical findings
revealed delusional disorder. After three weeks, the patient presented
to the clinic with postural tremor in the hands, and gait difficulties. A
cranial CT scan showed that he had bilateral basal ganglia, thalamus, and
centrum semiovale calcifications. The case illustrates the importance of
considering organic etiologies before diagnosing a patient, particularly
one who has late-onset presentation of psychosis.
