Can be subtle. It's best to discuss your exact symptoms in person with your doctor. Tias are focal neurologic deficits that last <24 hours. Typical examples are a visual field cut (like "a curtain cutting across your vision"), inabilty to talk or understand words, weakness in the hand, arm, foot, or leg - but a TIA can be subtle and hard to recognize too.
Symptosm. One-sided weakness, numbness, speech difficulty and visual deficits could indicate a tia.
Many. Focal weakness, numbness, speech problem, visual hearing problem of sudden onset, dizziness vertigo, confused behavior. Etc. Remember that by defination they should disappear.
Rarely yes. Not usually. But rarely yes.
Depends. Classic definition of TIA is neurologic deficit for up to 24 hours. In reality, TIA rarely lasts more than an hour. Tias can happen several times in 24 hours as well.
TIA. A transient ischemic attack (TIA) is caused by the transient blockage of a blood vessel in the brain. The symptoms depend on the blood vessel being blocked and can be difficult to recognize because they can be very variable. For example, symptoms can include weakness, numbness, confusion, difficulty speaking, changes in vision, dizziness, etc.
TIA. Symptoms of tia weakness or numbness of part of the body, loss of vision, slurred speech, confusion. Remember all these symptoms are transient.
Mini stroke. Tia's are strokes that resolve within minutes to hours without permanent damage. Typically focal deficits, unilateral sensory or strength problems. Can affect speech and vision. Need to be checked by a doctor.
TIA. Transient ischemic attack or mini stroke has obvious symptoms of either facial drop, paresthesias, weakness of extremities or a speech disorder. These symptoms are transient usually clear in a few hours.
TIA. Tia (transitory ischemic attack) happens when blood supply to a certain area of the brain gets cut off temporarily. This causes a neurologic deficit - weakness, numbness, visual deficit or difficulty with speech. While TIA usually resolves, it indicates that there is a problem with your heart or blood vessels that can cause another TIA or stroke.
Do people transient ischemic attack have high blood pressure? Do they have hbd while have the symptoms?
Yes they do. Blood clots atherosclerosis blood clots can float downstream from the heart and get caught in a tiny blood vessel (embolus) debris can occlude the blood vessels and stop blood flow. Blood vessels can leak and cause bleeding within the brain tissue. An intracerebral hemorrhage is often caused by high blood pressure which can cause small blood vessel walls to become thin and weak.
Frequently yes. Tia's often reflect reduced perfusion to the smaller blood vessels in the brain. This happens from persistent vessel wall thickening (an adaptation in chronic htn). In addition to bleeding possibilities (which more typically cause persistent symptoms, not transient), minor fluctuations in cerebral perfusion can cause transient symptoms in patients with thickened, pruned distal cerebral vessels.
Yes. High blood pressure is a common risk factor for tia. Patients having TIA often present with high blood pressure as well. Since TIA is often caused by lack of blood flow to the brain, the body tries to elevate the blood pressure to ensure proper perfusion of the brain.
Stroke. It is possible but of relatively low probability.
Rare. While possible, it is quite rare. Certain genetic syndromes, blood vessel abnormalities can result in strokes and tias in young adults. If there are concerning symptoms, such as one-sided weakness, numbness, speech difficulty or visual deficit, you should talk to your doctor.
Complex issue. Transients events can be due to heart defects, arrhythmia, blood pressure, blood sugar, drug effects, seizure, migraine, or blood vessel disorders. It would be important to have a thorough medical and neurological evaluation. Their may be genetic factors involved, especially defects in cholesterol and lipid metabolism. May be a high risk for completed stroke or even death.
