Researchers from the Karolinska Institutet in Sweden have found that long-term use of common cardiovascular drugs may offer protection against dementia. The study, which involved 88,000 individuals over 70 years old, found that using antihypertensive drugs, cholesterol-lowering drugs, diuretics, and blood-thinning drugs for more than five years was associated with a lower risk of dementia. Combinations of these drugs had stronger protective effects than if used alone. However, the use of antiplatelet drugs for stroke prevention may be linked to a higher risk of dementia due to increased risk of brain microbleeds. This discovery could lead to new treatments for dementia and highlights the importance of considering potential long-term cognitive effects when prescribing medications.
