If you have a silent stroke, you probably won't know it unless you happen to have a brain scan and the damage shows up. You may have slight memory problems or a little difficulty getting around. A doctor may be able to see signs of silent strokes without testing.
Researchers say that over time, the damage from silent strokes can accumulate, leading to more and more memory problems. "The more brain damage or injury that you have due to these silent strokes, the more difficult it is for the brain to function normally," Dr. Furie says.
Sudden numbness or weakness in the face, arm, or leg, especially on one side of the body. Sudden confusion, trouble speaking, or difficulty understanding speech. Sudden trouble seeing in one or both eyes. Sudden trouble walking, dizziness, loss of balance, or lack of coordination.
Some people have strokes without realizing it. They're called silent strokes, and they either have no easy-to-recognize symptoms, or you don't remember them. But they do cause permanent damage in your brain. If you've had more than one silent stroke, you may have thinking and memory problems.
Can an MRI detect silent strokes? Yes, MRI scans can detect silent strokes. Sometimes, a person may not know they have had a stroke or a transient ischemic attack, which doctors may also call a ministroke.
Usually, a silent stroke is discovered unexpectedly on a brain CT or brain MRI. These imaging tests can easily distinguish past strokes from recent strokes.
You will likely have a head CT scan or brain MRI. A stroke may show changes on these tests, but TIAs will not.
Lower levels of s-adiponectin are associated with ischemic stroke. Aging: the prevalence of silent stroke rises with increasing age with a prevalence rate of over twenty percent of the elderly increasing to 30%-40% in those over the age of 70.
Silent strokes occur when a clot blocks a blood vessel in the brain, but the person experiences no symptoms. Despite this lack of symptoms, silent strokes can cause damage to a small part of the brain.
Silent strokes can cause cognitive impairment, memory loss, visual field problems and migraines.
It's known that stress from work is bad for your health, including causing an increase in your risk for cardiovascular disease, particularly high blood pressure and heart disease. If you've wondered specifically if stress can cause a stroke, too, the answer is unfortunately, yes.
Some people will experience symptoms such as headache, numbness or tingling several days before they have a serious stroke. One study found that 43% of stroke patients experienced mini-stroke symptoms up to a week before they had a major stroke.
Men and women who have strokes often experience a similar set of symptoms that can be remembered using the mnemonic F.A.S.T.: face drooping, arm weakness, speech difficulty, time to call 911. Other signs include problems seeing out of one or both eyes and balance or coordination problems.
Tests to diagnose stroke include the following: Computed tomography (CT) uses X-rays to take clear, detailed pictures of your brain. It is often done right after a stroke is suspected. A brain CT scan can show if there is bleeding in the brain or damage to the brain cells from a stroke.
Some of the most common stroke mimics are seizures, migraine, fainting, serious infections and functional neurological disorder (FND). Once the person is diagnosed, they can have treatment or support to manage their symptoms.
Brain scans and tests
You should have a brain scan soon after symptoms start, within an hour of arriving at hospital if possible. The scan can show whether the stroke is due to a clot or a bleed. There are two main types of scan used: A computed tomography or CT scan.
If a stroke happens in your cerebellum or brainstem, the areas that control balance in the brain, you may be left with vertigo. This means having a feeling that you or the world around you are moving or spinning.
Strokes that block a brain artery usually cause a range of symptoms that may include vascular dementia. But some strokes don't cause any noticeable symptoms. These silent strokes still increase dementia risk.
A silent stroke is different from a transient ischemic attack (TIA), a momentary loss of brain function, says Dr. Seshadri. A TIA causes some symptoms, while a silent stroke, by definition, does not.
Undiagnosed stroke or misdiagnosed stroke means delayed treatment or no treatment at all. This allows brain cell death to continue, and can quickly escalate to preventable permanent brain injury or death.
Most people who have a mini-stroke feel fine after the event. In fact, many people don't even realize they've had one! Symptoms might include weakness, numbness, tingling, vision changes or difficulty speaking. Most symptoms are temporary and dissipate within minutes but sometimes can last up to 24 hours.
Benefits and risks of blood-thinning medication
Taking blood-thinning medication is often one of the main ways you can reduce your risk of a stroke if you have had a stroke or TIA, or have a heart condition.
