Core Tip
Core Tip: Bipolar disorder (BD) is an infrequently reported but disabling non-motor manifestation of Parkinson’s disease (PD). The presentation of a 68-year-old man with comorbid BD and PD illustrates the comorbidity’s typical features, such as BD occurring in the pre-motor phase of PD, its association with anxiety, apathy, and other non-motor symptoms, and its poor prognosis. Catatonia is an uncommon manifestation of treatment-resistant depressive episodes in comorbid BD and PD. When benzodiazepines for catatonia fail, clinicians should actively consider electroconvulsive therapy. Close collaboration between psychiatrists and neurologists is essential for early detection and proper management of coexisting BD and PD with catatonia.
