One of the most common stroke mimics is a seizure, which researchers believe account for as many as 20% of all stroke mimics. Other common stroke mimics include migraines, syncope, sepsis, brain tumor and metabolic derangement (low sodium or low blood sugar).
Overview. A transient ischemic attack (TIA) is a temporary period of symptoms similar to those of a stroke. A TIA usually lasts only a few minutes and doesn't cause permanent damage. Often called a ministroke, a TIA may be a warning.
Some of the most common stroke mimics are seizures, migraine, fainting and serious infections. Once the person is diagnosed, they can have treatment or support to manage their symptoms.
In the nation's emergency rooms, strokes are regularly misdiagnosed – about one in 10 cases, according to various published reports over the last decade. In many cases, the patient's mild, non-specific symptoms, such as a headache, vertigo, or inability to answer questions correctly, prompt a different diagnosis.
Call 9-1-1 immediately if any of these signs of stroke appear: Numbness or weakness in the face, arm, or leg; Confusion or trouble speaking or understanding speech; Trouble seeing in one or both eyes; Trouble walking, dizziness, or problems with balance; severe headache with no known cause.
Weakness or numbness of the face, arm or leg, usually on one side of the body. Trouble speaking or understanding. Problems with vision, such as dimness or loss of vision in one or both eyes. Dizziness or problems with balance or coordination.
An MRI can detect brain tissue damaged by an ischemic stroke and brain hemorrhages. Your doctor may inject a dye into a blood vessel to view the arteries and veins and highlight blood flow (magnetic resonance angiography or magnetic resonance venography).
Epilepsy. Epilepsy is one of the most frequent stroke mimics. Some symptoms, such as headaches, involuntary movements, incontinence or postictal confusion, may be helpful pointers against stroke.
Gliomas, meningiomas and hypophyseal adenomas are among the commonest primary tumors that may mimic a stroke. Metastatic lesions of the brain may have a similar presentation.
The only way to tell the difference between a ministroke and a stroke is by having a doctor look at an image of your brain with either a CT scan or an MRI scan. If you've had an ischemic stroke, it's likely that it won't show up on a CT scan of your brain for 24 to 48 hours. An MRI scan usually shows a stroke sooner.
A stroke, sometimes call a brain attack, happens in one of two ways: A blocked artery or a ruptured artery. A stroke, sometimes called a brain attack, occurs when something blocks blood supply to part of the brain or when a blood vessel in the brain bursts. In either case, parts of the brain become damaged or die.
Strokes may not be seen on a CT scan for several reasons. It can sometimes take several hours for the brain to appear abnormal after the onset of stroke. The affected region may also be a part of the brain that CT scans do not image well, such as the cerebellum or the brainstem.
Unlike a CT scan, which takes several hours to reveal any blockages of blood flow, an MRI can uncover any brain damage within an hour of the onset of the stroke symptoms.
Brain cells begin to die when they are deprived of oxygen and glucose. Permanent brain damage or death is possible if a stroke is not caught early.
Panic attacks are often confused with heart attacks or strokes. They share many of the same symptoms: Racing heart. Chest pains or tightness.
Yes, you can have a stroke and not know it. A stroke's effects can be undetectable if the stroke is small or if the tissue damaged does not serve a critical function. Evidence of the stroke would show on a CT scan or an MRI of the brain, but it might not produce symptoms.
The Difference Between Brain Tumors and Strokes
With a stroke, the symptoms happen quickly over a period of minutes or hours. With a brain tumor, the symptoms may come on so subtlely that those around the patient take little to no notice right away. “They may be willing to write it off,” said Jensen.
Usually, the first sign of a brain tumor is a headache, generally in conjunction with other symptoms.
An MRI scan shows brain tissue in greater detail, allowing smaller, or more unusually located, areas affected by a stroke to be identified. As with a CT scan, special dye can be used to improve MRI scan images.
Brain magnetic resonance imaging (MRI) is the preferred and most sensitive modality after transient ischemic attack (TIA) or minor stroke. It should include diffusion-weighted imaging (DWI) and should be completed within 24 hours of symptom onset1,2; its use is 3-fold.
5 How- ever, earlier studies have shown that MRI may not detect acute strokes in 10-20% of patients. 4-6 Few clinical details of the false-negative cases were provided. Although several aspects of MRI techniques, computer software, and scan interpretations have been improved, false-negative MRI results may still occur.
Depending on how serious your stroke is, you may stay in hospital for anything from a few days to a few months. You might move to a rehabilitation ward. You'll work with a team of health professionals specialising in stroke.
Typically, the time spent in a hospital after a stroke is between five days and a week. During this time, a stroke care team will make a detailed evaluation of the effects of the stroke before creating an appropriate recovery plan for you.
The typical length of a hospital stay after a stroke is five to seven days. During this time, the stroke care team will evaluate the effects of the stroke, which will determine the rehabilitation plan.
