    Area of Science:

    • Pharmacology
    • Neuroscience
    • Clinical Medicine

    Background:

    • Benzodiazepines are commonly prescribed for anxiety and insomnia.
    • Discontinuation can be challenging for chronic users.
    • Understanding withdrawal phenomena is crucial for patient care.

    Purpose of the Study:

    • To describe and analyze the withdrawal syndrome in patients attempting to discontinue benzodiazepine use.
    • To compare withdrawal symptoms between high-dose and moderate-dose users.
    • To investigate electroencephalogram (EEG) changes during benzodiazepine withdrawal.

    Main Methods:

    • Observational study of 10 patients experiencing difficulty discontinuing benzodiazepines.
    • Categorization into high-dose (mean 135 mg diazepam equivalent/day) and normal-dose (20 mg/day) groups.

  • Monitoring of withdrawal symptoms, including anxiety, sensory intolerance, perceptual disturbances, and weight loss.
  • EEG recordings during withdrawal and after a drug-free period.

    • Main Results:

    • All patients exhibited a withdrawal syndrome with severe anxiety and other symptoms upon gradual medication reduction.
    • The withdrawal syndrome was similar in both high-dose and normal-dose groups.
    • EEG changes observed during withdrawal were opposite to those seen upon initiation of diazepam treatment and tended to normalize after discontinuation.
    • Symptoms subsided within two weeks.

    Conclusions:

    • A significant benzodiazepine withdrawal syndrome can develop even after moderate daily dosage.
    • The severity and nature of the withdrawal syndrome appear consistent across different dosage levels.
    • EEG monitoring may provide insights into the neurophysiological changes associated with benzodiazepine withdrawal.
