Alcohol can trigger temporary depersonalization disorder. Quantitative EEG (qEEG) showed increased slow brain wave activity during episodes, suggesting metabolic changes contribute to these alcohol-induced symptoms.

Area of Science:

  • Neuroscience
  • Psychiatry

Background:

  • Presents a case of alcohol-induced depersonalization disorder.
  • Episodes were transient, linked to alcohol consumption, not psychogenic.
  • Distinguishes from chronic depersonalization syndromes.

Observation:

  • Three quantitative EEG (qEEG) studies were conducted.
  • One study during an active depersonalization episode.
  • Two studies when the subject was asymptomatic.

Findings:

  • Significant increase in slow wave activity (relative theta power) during symptomatic states.
  • Persistent occipital slowing observed 3 days post-remission.
  • EEG slowing resolved by 17 days after symptom amelioration.

Implications:

  • Suggests a transient metabolic encephalopathy associated with alcohol-induced depersonalization.
  • EEG slowing's time course offers insights into the condition's pathophysiology.
  • Highlights the utility of qEEG in understanding alcohol-related psychiatric episodes.
