What Is A Stroke And The Different Types Of Stroke
Lack of blood: Generally, there are 2 types of stroke that ultimately result from not enough oxygen getting to the brain: 1 - ischemic (represents ~70%) is due to a blockage that results in not enough blood flow 2 - hemorrhagic (which is less often) results when a blood vessel bursts and blood spills out uncontrollably, may end up resulting compression on the brain given the limited volume in the skull. ...Read more
Various symptoms: 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. ...Read more
Duration: The main difference is in how long the neurological symptoms last. In a TIA they resolve fairly quickly (<1 day and often in an hour or two). In a stroke they last longer and are often permanent. The fact that the symptoms resolve with a TIA does not mean everything's okay--a TIA can be a serious sign of underlying vascular disease and should be thoroughly evaluated. ...Read moreSee 1 more doctor answer
Stroke v, heart atta: Most strokes are caused by obstruction of arteries by atherosclerotic plaques ( cholesterol plaques) and clots which is the same cause of the myocardial infarctions. Brain infarcts are strokes. Heart infarcts are heart attacks. Intracraneal bleeding causes strokes too. ...Read moreSee 1 more doctor answer
Location dependent: This depends upon the location of the stroke. It could include weakness, language difficulties, sensory abnormalities and visual loss. Other possibilites include personality change, neglect of one side of the body, transient visual hallucinations, inability to swallow, facial weakness and numbness, gait disorders, tremors and spasticity. The list is not all inclusive. ...Read moreSee 1 more doctor answer
CVA: Stroke is blockage of blood vessels causing secondary death of brain tissue. This can occur due to local thrombosis or distal embolism. The latter might be due to a clot from the heart, the former associated with hypertension, diabetes, high blood fats, homocysteine. Could present with sudden focal weakness of arm and leg, loss of speech or vision, gait imbalance, etc. ...Read moreSee 1 more doctor answer
Here's a few: Tia's will last a shorter time - pa's will peak before fading. Any paralysis or numbness is more likely with tia. Pa will often have other elements - rapid breathing, shaking, thumping heartbeat leading into the attack. Also, history - strokes are rare in young people and pa is more common in younger adults. But both are painful and it would not be foolish to go to an er or urgent care to be sure. ...Read more
It varies.: A mini stroke typically refers to a transient ischemic attack which resolves on its own. There can be different symptoms, depending on the area affected. But unlike a stroke a TIA doesn't destroy brain cells or cause permanent disability. However, tias may recur and each TIA increases the risk of a subsequent stroke. You should talk to your doctor and get evaluated appropriately. ...Read moreSee 2 more doctor answers
Many causes: hemorrhagic stroke can happen from severe elevation in blood pressure (most common), or from an ischemic stroke transforming into a hemorrhagic, or a subarachnoid hemorrhage from a ruptured aneurysm, or from an AVM (arteriovenous malformation), or a large cortical brain hemorrhage from an amyloid angiopathy (in elderly with dementia) etc etc ...Read more
Same as a stroke: A mini-stroke or TIA (transient ischemic attack) is a stroke. However, it is a stroke that goes away, in as much as a few minutes to as long as 24 hours. If a stroke persists longer than 24 hours, it is generally considered permanent, though most tias resolve in a few hours, and the longer that it persists, the less likely it is going to go away. Be seen immediately for a stroke. ...Read moreSee 1 more doctor answer
Evaluation: If you are experiencing symptoms that you could interpret as a TIA or a panic attack it would be best to seek medical evaluation urgently. There is no way to give you any useful information on-line. The experience and education of a physician is needed with this one. See someone today, please. ...Read moreSee 1 more doctor answer
Risk factors include: Hypertension, diabetes, high blood fats (especially triglycerides), high homocysteine, cigarette smoking, alcohol abuse, drug abuse (especially sympathomimetic amines, like cocaine, speed), trauma (arterial dissection), arteritis or vasculitis (lupus, etc), vascular malformations (aneurysm, avm), emboli(distant blood clots from heart, or paradoxical like pfo), and genetic such as mthfr mutations. ...Read more
