An atypical case of corticobasal syndrome with psychotic depression and delusional jealousy

ABSTRACT

Corticobasal syndrome (CBS) is one of the Parkinson-plus disorders. While initially defined as a movement disorder rather than cognition, it is now known that CBS is related to various psychiatric symptoms. We describe a patient clinically diagnosed with CBS whose initial presentation was psychiatric and rather atypical. His clinical picture included psychotic depression and delusional jealousy. Misdiagnosing these syndromes may delay the initiation of the treatment and worsen the patients’ condition, as well as increase the burden of the caretakers. Finally, COVID-19-related changes in the organization of health services complicated the diagnosis and follow-up processes of this patient.
