Brain stimulation therapies show promise for treating complex bipolar disorders across all mood states and cognitive dysfunction. Further research is needed to confirm efficacy and long-term effects.
Area of Science:
- Neuroscience
- Psychiatry
- Medical Technology
Background:
- Bipolar disorders present complex challenges with limited effective treatments for all mood states.
- Current options often fail to address residual cognitive deficits during euthymic periods.
Purpose of the Study:
- To review current research on brain stimulation techniques for bipolar disorders.
- To evaluate efficacy, tolerability, and cognitive effects of various neuromodulation methods.
Main Methods:
- Comprehensive literature search of Embase, PubMed/MEDLINE, and APA PsycINFO databases up to February 2022.
- Prioritization of reviews, meta-analyses, and randomized controlled trials for an up-to-date overview.
Main Results:
- Evidence for brain stimulation in bipolar disorders is growing, offering potential across manic, depressive, and mixed states.
- These therapies may also address cognitive impairments during periods of mood stability.
Conclusions:
- Brain stimulation offers a promising avenue for comprehensive bipolar disorder management.
- Larger, long-term randomized controlled trials are essential to validate efficacy, tolerability, and cognitive impact.
