Although deep brain stimulation (DBS) may result in dramatic motor improvement in people with Parkinson's disease (PD), it has been correlated with a number of postoperative psychiatric side effects. We report a case of a person with PD experiencing depression and hypomania following DBS surgery. We provide a detailed report of the patient's personal experiences dealing with and managing these psychiatric side effects for three years. Providing a personal narrative focusing on detailed patient subjective experiences complements reports that give insight into the short- and long-term effects of DBS on established psychiatric measures and neurologic activity. But, most importantly, such a qualitative approach provides prospective patients and clinicians with a broader ethical picture of real-life challenges faced and coping strategies employed by PD patients treated with DBS who are experiencing psychiatric adverse events. This case study reinforces the ethical need to disclose the potential risk of harm to prospective patients as well as the importance of establishing a multidisciplinary postoperative supportive group.
