Late-Onset Psychogenic Chronic Phonic-Tics

Abstract

Background: Tics beginning in late adulthood often have an identifiable etiology. Psychogenic tics with onset around 60 years of age are rarely described in the literature. Case Report: A 67-year-old female had experienced phonic tics for 8 years. Episodes occurred without premonitory sensations and precipitant factors, and she could not suppress them. She had no history of childhood tic disorder, and secondary causes of tics were excluded. She was diagnosed with psychogenic tics and treated with quetiapine with mild improvement. Discussion: When physicians are faced with no identifiable cause of tics combined with certain clinical clues, a psychogenic disorder must be suspected.
