You have probably heard of a stroke, which is a brain injury that occurs when the blood supply to part of the brain is interrupted. Without blood flow, this brain tissue begins to die along with the functions controlled by that part of the brain. As a result, many stroke survivors experience cognitive and emotional deficits, like problems with memory, speech, motor movement, and personality. The levels of stroke damage on the brain vary from person to person. Most strokes are ischemic, meaning they are caused by a blood clot that blocks an artery leading to the brain. Hemorrhagic strokes account for a small percentage of all strokes and are caused by a burst blood vessel that leaks blood into the brain and damages the surrounding tissue.
Transient Ischemic Attack (TIA)
However, not many people have heard of a transient ischemic attack (TIA), which is often referred to as a mini-stroke. TIA begins just like an ischemic stroke, with a blood clot blocking an artery to the brain. However, in this case, the blockage is only temporary and resolves on its own. A TIA usually lasts up to an hour. While TIA symptoms may go away quickly, it should not be ignored. Experiencing a TIA increases the predictability of future stroke or TIAs occurring. If you or a loved one experienced a stroke or TIA, it is integral that you get to an emergency department quickly.
Risk Factors for Stroke & TIA
- Excess weight
- High cholesterol
- Irregular heart rhythm
- Carotid artery stenosis
Short Term Effects of Stroke & TIA
- Uneven face
- Dropping things
- Falling over
- Changes in vision
- Difficulty speaking
- Confusion and mental fog
Long Term Effects
In most cases, a TIA will resolve itself and not cause any adverse long term effects. However, an ischemic stroke can cause permanent disability, depending on the region of the brain in which the clot occurs and the intensity of the stroke. With new treatments, such as CBC Health’s cord blood stroke treatment, doctors are able to slow and even reverse the cognitive, motor, and behavioral side effects of stroke.
In order to protect yourself and your loved ones, it is important to know the warning signs of a stroke or TIA. This ensures that you know exactly what to do during the attack. Learn more about stroke prevention, recovery, and treatment by visiting cbchealth.ch.
