Transient Ischemic Attacks Linked to Increased Long-Term Dementia Risk

Mini-Stroke Linked to 34% Higher Dementia Risk, with One in Five Ontario Patients Diagnosed Over About Seven Years

A large Ontario study linked mini-strokes to a 34% higher dementia risk, with about one in five patients later diagnosed. It shows an association, not a cause.

Transient ischemic attacks linked to increased long-term dementia risk

Having a transient ischemic attack (TIA) is associated with an increased risk of developing dementia, according to a new study published September 23, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Transient ischemic attack associated with increased risk of dementia

Having a transient ischemic attack (TIA) is associated with an increased risk of developing dementia, according to a new study published in Neurology. The study does not prove that a transient ischemic attack causes dementia; it only shows an association.

Mini-Stroke Linked to Increased Dementia Risk

Why Might a Mini-Stroke Raise Dementia Risk? Is there something about having a TIA that increases the risk of dementia, or could it be that the same risk factors that make a mini-stroke more likely also increase the likelihood of dementia? The answer is probably some combination of both, says Joundi. “TIA and dementia certainly share many risk factors, including high blood pressure, diabetes, atrial fibrillation, and other vascular diseases,” he…
