What Is The Pathophysiology Of Tia
Transient Ischemic Attack (Mini Stroke) (Definition)
Transient ischemic attack (TIA), is a condition where a blood vessel in the brain is temporarily blocked by a blood clot, causing neurologic symptoms, such as weakness in an arm or leg, or sensory changes. The symptoms are similar to a stroke, but are temporary, disappearing within minutes after the clot breaks apart. ...Read more
Absolutely: Someone who is having tias should most definitely have their carotids checked since the carotid arteries are the number one source for embolic strokes. In "symptomatic" patients, such as someone who is having tias, a carotid blockage of 50% or more warrants intervention. ...Read moreSee 1 more doctor answer
Rare but possible: Vasospasm in the brain occurs when blood and its breakdown products are present in the spinal fluid around blood vessels. The most common reason is rupture of brain aneurysm, but there are other conditions. Vasospasm causes the larger vessels (arteries, arterioles) to clamp down or contrict, thus reducing blood flow. This can cause strokes or tias. ...Read moreSee 1 more doctor answer
I suppose so: Strokes and tias are, at their underlying cause, basically the same thing. Both involve clots impairing blood flow to brain cells. Tias are just when the clot fortunately dissolves in enough time such that no permanent damage has occurred. Oranges are in general probably good and better than foods with high salt, fat, sugar or cholesterol content. ...Read more
Stroke prevention: Optimal stroke prevention depends on minimizing risk factors, whether a person is outdoors or not. If there is no carotid artery disease, then risk factor modification includes keeping a healthy blood pressure, blood sugar, cholesterol, no smoking, and taking special medication if there is a heart rhythm irregularity called atrial fibrillation. ...Read more
What can be done for stroke prevention for someone who is having tias but is very active outdoors?
TIA: Not enough information to even begin... First things first: overweight? High blood pressure? Smoking? High cholesterol? Yourself? Active outdoors doesn't help... If you have high blood pressure and be "active" may actually endanger you (if you have high blood pressure it goes up even higher during exercise). ...Read moreSee 2 more doctor answers
