What Are Symptoms of Stroke

The term stroke refers to a sudden decrease in blood flow to an area of the brain. Strokes can be either hemorrhagic, caused by bleeding from one of the blood vessels, or ischemic, caused by blockage of a blood vessel supplying the brain. Regardless of the cause, a stroke can cause a temporary or permanent loss of neurologic function from the area of decreased blood flow. According to MayoClinic.com, a stroke with symptoms that resolve within 24 hours is called a transient ischemic attack, or TIA, also known as a "ministroke."
Weakness
Weakness is a common stroke symptom that may resolve within 24 hours, according to the "Massachusetts General Hospital Handbook of Internal Medicine." The weakness usually occurs on the side of the body opposite from the side of the stroke. The weakness can be limited to just one part of the body, such as one arm, or it can affect the whole body.
Slurred Speech
According to MayoClinic.com, slurred speech is one of the most common symptoms of stroke that may resolve within 24 hours. The slurred speech may be due to decreased blood flow to the nerves that control the tongue and vocal chords or to more central brain areas that control speech.
Blindness
Temporary blindness that people experience during a stroke that lasts less than 24 hours is called amaurosis fugax and, according to the Cleveland Clinic, is one of the most common temporary stroke symptoms. The blindness can affect either one or both eyes.
Dizziness

People with stroke symptoms that last less than 24 hours often experience dizziness. According to the "Massachusetts General Hospital Handbook of Internal Medicine," those symptoms may also be accompanied by a loss of balance and coordination.
