Small Seizures Vs. Mini Strokes
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
Electrical: Fainting refers to loss of consciousness. This may be due to a variety of problems. A seizure may or may not result in a loss of consciousness, but specifically is a result of abnormal synchronized electrical activity in the brain. There are several types of seizures, only some of which result in synchronized muscle activity (often called a convulsion). ...Read moreSee 1 more doctor answer
Reversibility: Mini-strokes are colloquially thought of as transient ischemic attacks, or tias, which are neurologic deficits that may resolve over a relatively short period of time. This is in contrast to a typical full blown stroke that does not resolve, though may improve with hypothermia, medications including possibly lytic therapy (if a candidate) or revascularization procedures. ...Read moreSee 1 more doctor answer
Much difference: A seizure is a sudden electrical surge in the brain usually related to brain malformation or dysplasia. Seizures can also be related to tumors or metastasis in the brain. Damage to brain by trauma, ischemia, and metabolic disorders can also result in seizure. Stroke is usually from blood vessel clot or narrowing due to atherosclerosis, high blood pressure, and hemorrhage from aneurysm. ...Read moreSee 1 more doctor answer
Bleed vs blockage: Hemorrhagic strokes usually refer to bleeds within the parenchyma or substance of the brain (though subarachnoid bleeding - from an aneurysm or such- is rarely and loosely referred to as a hemorhagic stroke). An ischemic stroke is when brain tissue dies (infarcts) due to a lack of blood flo from a clot or small vessel blockage. It is not uncommon for some bleeding to occur within an infarct. ...Read moreSee 1 more doctor answer
Can be the same: An embolism is a blood clot that travels and can cause a blockage of the artery. A stroke can be caused by different things, such as an embolism or artery blockage. A stroke can also be caused by hardening of the arteries with blockage, or even an artery aneurysm that bursts with bleeding. ...Read more
Convulsion or seizr: A convulsion describes a certain type of seizure, one that includes loss of consciousness and involuntary movement on both sides of the body. A seizure is an aberrant electrical discharge on the surface of the brain, which may involve loss of consciousness, or not, as well as involuntary movement, or not. There are many types of seizures, too many to describe in this small box. ...Read more
TIA or seizure?: A petit mal seizure is caused by an electrical disturbance in the brain, it normally lasts about 20 seconds. It is common for it to occur over and over. It often causes involuntary movement, sensation, or visual disturbance. A TIA is also a mini stroke. It is caused by loss of blood flow to part of the brain, resulting in loss of function. It lasts less than 24 hours. Hope that helps! ...Read moreSee 1 more doctor answer
Degree: A migraine's main feature is pain whereas a TIA is marked by loss of body function. Both are related to changes to circulation in the brain. Migraine may interfere with your ability to function but to a much more limited extent. Some types of migraine have more features of a TIA and need careful evaluation to determine that they are not symptoms of an impending stroke. ...Read moreSee 1 more doctor answer
Basically same: Usually stroke from clot refers to embolism-clot formed somewhere else & travelled to affected area. Ischaemia refers to gradual progressive closure of an artery leading to ischaemic necrosis. Often the conditions may overlap & a clot may form at the site of obstructing artery. ...Read more
Heart and brain: A cardiac arrest happens when there is a rhythm or pumping problem with the heart so bad that there is essentially not enough blood flow to support life. Ma stroke happens when there is not enough oxygen delivery to the brain (or spinal cord), and the neurons (brain cells) die. ...Read more
Many differences: There are a number of classic changes found in the brains of someone with Alzheimer's disease. There is a generalized wasting of the brain which can be see on CT Scan. Microscopic examination of autopsied brains, show that many neurons (brain cells) are disarrayed, forming tangles; and there are plagues made of a substance called amyloid. There are also chemical differences, eg. low acetylcholine ...Read moreSee 1 more doctor answer
Two types: Two types depending on which part of the brain is affected or sometimes they can happen together. One is expressive or motor aphasia where patient can understand words but can not or have difficulty expressing himself or talking. Second is receptive or sensory aphasia where patient talk but does not make sence. Some other types like anomia where patient has difficulty naming. Also global or mixed. ...Read more
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
