Can dehydration cause TIA?

Doctors now suggest severe dehydration, rather than blockage of an artery, may have caused Chiles to have a transient ischemic attack, or temporary decrease of blood flow to the brain.

Can dehydration cause mini strokes?

In fact, some 60% of stroke patients are dehydrated, and it's possible that the lack of fluids could be the cause of the stroke or a contributing factor. When you don't consume enough fluids, your blood can thicken and move slowly, potentially backing up in a blocked or narrowed blood vessel and resulting in stroke.

What is the most common cause of TIA?

The underlying cause of a TIA often is a buildup of cholesterol-containing fatty deposits called plaques (atherosclerosis) in an artery or one of its branches that supplies oxygen and nutrients to the brain. Plaques can decrease the blood flow through an artery or lead to the development of a clot.

What increases risk of TIA?

Risk factors for TIA include family history of stroke or TIA, age above 55 years or older, higher risk of TIA in males than females, high blood pressure, diabetes mellitus, and tobacco smoking. Genetics, race, and imbalance in lipid profile are other risk factors of TIA.

Does drinking water prevent a stroke?

Drinking enough water regularly prevents dehydration. This may play a role in keeping the blood less viscous, which in turn prevents a stroke.

What can bring on a mini-stroke?

Blood clots are the leading cause of ministrokes. When there's a clot in an artery that's connected to the brain, blood can't flow as freely as it needs to, which means the brain doesn't get the oxygen it needs to work properly.

Are there warning signs days before a stroke?

- Warning signs of an ischemic stroke may be evident as early as seven days before an attack and require urgent treatment to prevent serious damage to the brain, according to a study of stroke patients published in the March 8, 2005 issue of Neurology, the scientific journal of the American Academy of Neurology.

What is a low flow TIA?

Sometimes a TIA is caused by a sharp drop in blood pressure that reduces blood flow to the brain. This is called a "low-flow" TIA. It's less common than a TIA caused by a blood clot.
