Summary

Long-term opioid use can cause cognitive impairment, affecting reaction time and activity levels. Research is needed on patients with chronic non-malignant pain, who consume most opioids.

Tapering off long-term opioid therapy in chronic non-cancer pain patients: A randomized clinical trial.

European journal of pain (London, England)·2018

Area of Science:

  • Neuroscience
  • Pharmacology

Context:

  • Opioid use is rapidly increasing globally.
  • Long-term opioid therapy presents challenges in cerebral function.
  • Cancer patients and individuals with addiction show cognitive effects.

Purpose:

  • To review psychomotor and cognitive testing methods for patients on long-term opioid treatment.
  • To summarize current findings on opioid-induced cerebral dysfunction.
  • To identify research gaps in this field.

Summary:

  • Long-term opioid treatment is linked to increased reaction time and sedation in cancer patients.
  • Opioid use in drug addicts may lead to reduced general activity.
  • Patients with chronic non-malignant pain, major opioid consumers, lack studies on cerebral dysfunction.

Impact:

  • Highlights the need for standardized cognitive and psychomotor assessments in long-term opioid users.
  • Emphasizes the necessity of research into opioid effects on patients with chronic non-malignant pain.
  • Informs clinical practice and future research directions for managing opioid-related cognitive issues.
