Abstract:


Background: Deep brain stimulation (DBS) is a modern neuromodulation method used in the treatment of advanced movement disorders such as Parkinson’s disease (PD) and dystonia. Patients with PD may have multiple psychiatric comorbidities, notably anxiety, de-pression, mania or hypomania, and psychosis. DBS surgery may indirectly alleviate psychiat-ric symptoms by allowing reduction of dopaminergic medications, or as a result of functional improvement. Patients who are considering DBS for PD often have more advanced disease and may be more vulnerable to perioperative psychiatric decline. Albeit infrequently, in-creased depression, apathy, irritability, hypomania or mania, and suicidal behavior have been observed after DBS surgery. Objective: The stydy aimed to present current evidence and empirical recommendations for the management of the psychiatric symptoms in patients with PD treated with DBS. Method: Relevant literature was reviewed and synthesized, along with recommendations in-formed by the authors’ clinical experience in a large, academic DBS center. Results: Careful evaluation of DBS candidacy, including assessing the risk for perioperative psychiatric decompensation is advised. Maintaining at least eight weeks of psychiatric stabil-ity prior to DBS surgery is strongly recommended. Postoperative management can be chal-lenging due to an advanced disease, concurrent psychiatric comorbidities, and possible DBS stimulation-related effects on mood and impulse control. Stimulation-induced elevated mood states (mania, hypomania) have started to be recognized as distinct clinical entities, although not included in the current psychiatric nomenclature. Conclusion: Insufficient evidence-based strategies for managing psychiatric symptoms in PD patients with DBS exist at this time. Further research is necessary to uncover best practices in this complex, expanding field.
