Overview
Amnestic disorder caused by drugs refers to memory impairment and cognitive dysfunction directly attributable to substance use, often seen in older adults with polypharmacy 12.Diagnosis
History of substance use and temporal relationship to cognitive symptoms
Cognitive assessment tools (e.g., Mini-Mental State Examination, Montreal Cognitive Assessment)
Exclusion of other causes of cognitive impairment through neuroimaging and laboratory tests 1Management
Review and potentially adjust current medication regimen to minimize unnecessary drugs 2
Cognitive rehabilitation and supportive therapies as adjunctive treatments
Specific drug tapering or discontinuation guided by clinical judgment and patient response 1Special Populations
Elderly: Higher risk of drug-related cognitive issues due to polypharmacy; careful medication reconciliation and patient education are crucial 2Key Recommendations
Conduct thorough medication reconciliation in elderly patients to align self-reported drug use with medical records to prevent drug-related cognitive impairments (Evidence: Moderate) 2
Regularly assess and adjust medication regimens to minimize the risk of drug-induced amnestic disorders, especially in those with perceived poor health (Evidence: Moderate) 2
Educate patients on the importance of accurate reporting of drug use to healthcare providers to improve congruence and health outcomes (Evidence: Expert opinion) 1References
