A TIA causes some symptoms, while a silent stroke, by definition, does not. But both are warning signs to pay attention to the well-known risk factors for stroke, such as cholesterol levels, blood pressure, obesity, and smoking.
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.
During a silent stroke, an interruption in blood flow destroys areas of cells in a part of the brain that is "silent," meaning that it doesn't control any vital functions. Although the damage will show up on an MRI or CT scan, it's too small to produce any obvious symptoms.
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.
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.
These brief episodes are transient ischemic attacks (TIA), sometimes called “mini-strokes.” They still should be taken seriously, because they tend to be signs of underlying serious conditions that can lead to a full stroke, even possibly in the few days following a TIA event if not evaluated and treated for a TIA.
A “mini-stroke" may not cause permanent brain damage, but it's a warning sign that you could be at risk for a debilitating—or deadly—stroke. Approximately one in three American adults has experienced a symptom consistent with a “mini-stroke,” sometimes called a transient ischemic attack (TIA).
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.
A person's life expectancy after a mini stroke reduces by around 4% in the first year following the attack in comparison to people who have not had one. In the following 9 years, life expectancy reduces by 20%. These statistics come from a 2019 review .
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.
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.
Treatment may include: Thrombolysis, a process used to dissolve blood clots and restore blood flow through the use of medication. Use of medication to treat an underlying condition like high blood pressure (a risk factor for silent strokes)
being sick. dizziness. confusion. difficulty understanding what others are saying.
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.
Personality changes after a stroke can include: Not feeling like doing anything. Being irritable or aggressive. Being disinhibited – saying or doing things that seem inappropriate to others.
Chronic stress can indirectly cause a stroke or TIA (transient ischemic attack or mini stroke). For instance, chronic stress can lead to high blood pressure, which is a known risk factor for stroke and heart disease. Stress can also cause inflammation in the arteries all over the body.
A transient ischaemic attack (TIA), or mini stroke, happens when there is a temporary disruption in the blood supply to part of the brain. The disruption in blood supply results in a lack of oxygen to the brain. This can cause sudden symptoms like those of a stroke.
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.
Aspirin and other antiplatelet medicines
You'll probably be given low-dose aspirin straight after a suspected TIA. Aspirin works as an antiplatelet medicine. Platelets are blood cells that help blood to clot. Antiplatelet medicines work by reducing the ability of platelets to stick together and form blood clots.
