Tag: Brain bleeding

Every year in the United States, nearly 800,000 people suffer a stroke. While blood thinners are often used to prevent clot-related strokes, it is a crucial and valid question to ask: can blood thinners cause strokes and bleeding in the brain? The answer is complex, balancing the life-saving benefits of these medications against their inherent risks.

In clinical trials for the Alzheimer's medication LEQEMBI (lecanemab), up to 12.6% of patients experienced brain swelling (ARIA-E) and 17.3% experienced brain bleeding (ARIA-H), which was higher than in the placebo group. While often asymptomatic, these side effects can, in rare cases, manifest with serious, stroke-like symptoms or lead to fatal brain hemorrhages, raising concerns about if **LEQEMBI can cause a stroke**. The U.S. Food and Drug Administration (FDA) has issued a black box warning to highlight this significant safety risk.
