Medications Intended for Other Diagnoses – and Which Can Potentially Affect Alzheimer's

# Medications Intended for Other Diagnoses That Can Potentially Affect Alzheimer's

An overview of medications originally developed for other diseases but which have shown interesting signals for Alzheimer's.

GLP-1 Agonists (Diabetes Medication)

Examples: Semaglutide (Ozempic/Wegovy), Liraglutide

Large observational studies show a lower risk of dementia in diabetics treated with GLP-1 agonists. Clinical trials are ongoing specifically for Alzheimer's.

Possible mechanism: Improved insulin signaling in the brain, anti-inflammatory effect, protection against neuronal cell death.

Lithium

Original indication: Bipolar disorder

Epidemiological data consistently show a lower risk of dementia in lithium users. Microdose studies (300 µg) show promising results.

Possible mechanism: Inhibits GSK-3β (involved in tau phosphorylation), neuroprotective effect.

Losartan (Blood Pressure Medication)

Original indication: Hypertension

Angiotensin II receptor blockers (ARBs) have been associated with a lower risk of dementia in observational studies compared to other blood pressure medications.

Possible mechanism: Improved cerebral blood flow, reduced neuroinflammation, protection of the blood-brain barrier.

Statins

Original indication: High cholesterol

Mixed results. Observational studies positive, randomized studies negative. Possibly most beneficial with early treatment.

Important to note

None of these medications are approved for the treatment of Alzheimer's. Always discuss with your doctor before making changes to your medication.
