Dementia is a common condition in older adults, with over 6 million people being diagnosed with Alzheimer’s disease in the U.S.1 As many as 1 in 9 people over the age of 65 have Alzheimer’s disease. After the age of 85, that prevalence rises to 1 in every 3 people having the disease.
While many factors have been associated with the development of dementia, few interventions have conclusively proven to reduce dementia incidence. Two interventions that may reduce patient risk are controlling blood pressure and recommending a Mediterranean diet.2,3
Patients with signs or symptoms of cognitive impairment should be evaluated for dementia with a validated tool. A comprehensive physical exam, relevant history, and attempts to evaluate for reversible causes should be completed before making the diagnosis.4
Older medications, cholinesterase inhibitors (e.g., donepezil) and memantine have a limited role in management. A response to treatment, if it occurs, is time limited and carries a risk of side effects such as nausea, vomiting, bradycardia, hypertension, and dizziness.5 Continuously reassess the benefit and risks of medications, if used.
Newer medications, such as monoclonal antibodies to reduce amyloid deposits in the brain, have shown potential benefit. Lecanemab (Leqembi) slowed cognitive decline by 0.45 points on an 18 point scale compared to placebo over 18 months in patients with mild cognitive impairment or mild Alzheimer’s disease.6 It is not clear whether such a small change would be noticed by many patients, families, or clinicians.7 Testing requirements, logistics relating to infusions, cost of infusions and required testing throughout treatment can be burdensome, in addition to side effects from lecanemab such as cerebral edema, effusion, and hemorrhage. The decision to use lecanemab should be based on a clear discussion of the risks and expected benefit from treatment. It will not stop or reverse cognitive decline.
Advance care planning (ACP) is a continuous, dynamic process of reflection and dialog between a person with dementia, those close to her or him, and their health care providers concerning the patient’s preferences and values in future treatment and care, including end-of-life care.8 Documenting the patient’s wishes allows patients to have more control in care and can avoid unnecessary or unwanted treatments. Numerous resources (noted further down this page) can assist patients and families in having discussions and documenting key decisions.
