Summary

Vagus nerve stimulation (VNS) may impact mood and cognition, similar to antiepileptic drugs. This review examines existing research on VNS effects in patients with neuropsychiatric disorders.

Area of Science:

  • Neuroscience
  • Psychiatry

Background:

  • Antiepileptic medications are known to affect mood and cognitive functions.
  • Emerging evidence suggests vagus nerve stimulation (VNS) may also influence these domains.

Purpose of the Study:

  • To review and synthesize published data on the effects of VNS on mood and cognition.
  • To evaluate VNS as a potential modulator of affective and cognitive functions in neuropsychiatric conditions.

Main Methods:

  • Systematic literature search for studies reporting mood and cognitive outcomes in patients undergoing VNS.
  • Analysis of evidence regarding VNS-induced changes in affective and cognitive domains.

Main Results:

  • VNS has been associated with alterations in mood and cognitive performance in patients with various neuropsychiatric disorders.
  • The specific effects of VNS on mood and cognition appear to be complex and varied.

Conclusions:

  • VNS may represent a therapeutic strategy for modulating mood and cognitive deficits in neuropsychiatric populations.
  • Further research is warranted to elucidate the precise mechanisms and optimize VNS for affective and cognitive benefits.
