A stroke occurs when oxygen flow to the brain is disrupted. Within minutes of a stroke, brain cells begin to die from lack of oxygen. As more cells die, parts of the brain become damaged and may no longer function properly.
Three main types of strokes
* Ischemic stroke is caused by a blockage in the blood vessels of the brain. It is the most common type of stroke.
* Transient ischemic stroke (TIA), also known as a mini-stroke, is a type of ischemic stroke in which blood flow is blocked for only a few minutes. TIA’s are often a warning sign that a more severe stroke may occur.
* Hemorrhagic stroke is caused by a blood vessel in the brain leaking blood or bursting. The buildup of blood puts pressure on brain cells, which causes damage.
Signs & Symptoms
* Numbness or weakness in the face, limbs, or body on one side
* Sudden vision trouble
* Confusion and difficulty speaking
* Severe headache
* Dizziness and trouble with balance or walking
Early identification of a stroke is essential to minimize harm to the brain. Every minute is critical for getting fast and effective treatment.
Knowing the warning signs of a stroke means you can quickly seek medical help. Getting medical attention within the first few hours of a stroke ensures the best possible outcome and recovery. If you suspect a stroke, call 911 right away.
Effects of a stroke
The brain controls many essential body functions, including movement, speech, breathing, digestion, memories, and emotions. The damage caused by a stroke can lead to long-term disability or even death.
The exact impact of a stroke depends on the area of the brain affected, the length of time between the start of the stroke and treatment, and any underlying conditions.
Possible side effects of a stroke include:
* Weakness or paralysis on one or both sides of the body
* Difficulty forming or understanding speech
* Impairment of memory, concentration, thinking, and judgment
* Trouble chewing or swallowing
* Bladder and bowel control issues
* Depression
