Parkinson's disease - Management
How do I manage daytime hypersomnolence in people with Parkinson's disease?

  • Advise people who have sudden onset of sleep without awareness or warning signs not to drive and to consider any occupational hazards.
  • Initial management of daytime hypersomnolence depends on its likely cause:
    • Anti-parkinsonian medication (such as dopamine agonists):
      • Seek specialist advice.
    • Sedating medication (such as antihistamines, antipsychotics, and some antidepressants):
      • Reduce, stop, or use an alternative medication; seek specialist advice if necessary.
    • Inadequate rest at night:
    • Dementia.
  • Consider requesting advice from, or an interim referral to, the person's Parkinson's disease specialist team, so that:
    • Medication that could be causing or contributing to daytime hypersomnolence can be reduced or stopped.
    • Modafinil can be considered for daytime hypersomnolence (off-licence use). However:
      • Modafinil is contraindicated in people with uncontrolled moderate to severe hypertension, and in people with arrhythmias.
      • Modafinil is associated with skin and subcutaneous tissue reactions, and with the development of neuropsychiatric disorders.
