Medication / drugs
- Antiepileptic drugs
- KCNQ2/3 opener (retigabine).
- Drug use (e.g., ecstasy intoxication).
- Statins (simvastatin, atorvastatin; both agents are lipophilic and cross the blood–brain barrier): In one study, physicians had reported various memory disturbances (ranging from isolated memory lapses to retrograde amnesia) in 3.03% of statin users during the course of therapy. These disturbances also occurred in 2.31% of statin nonusers. The adjusted odds ratio was 1.23, which was significant at a 95% confidence interval of 1.18 to 1.28. This indicates a slight increase in memory disorders. The association was more marked in the first 30 days of therapy (0.08% of statin users versus 0.02% of nonusers).
- Drug side effects, unspecified
