A stroke can happen suddenly, but sometimes the body may give warning signs before a major event. These signs may be brief, mild, or easy to dismiss. Some people feel dizzy for a few minutes, notice temporary weakness, struggle to find words, or have blurred vision that disappears quickly. Because the symptoms may pass, many people ignore them.
That can be dangerous.
A stroke happens when blood flow to part of the brain is blocked or when a blood vessel in the brain bursts. Without enough oxygen, brain cells can be damaged quickly. That is why fast treatment matters. The CDC says to call emergency services right away if someone has sudden numbness or weakness, confusion, trouble speaking, trouble seeing, trouble walking, dizziness, loss of balance, or a severe headache with no known cause.
Some warning signs may actually be a transient ischemic attack, often called a TIA or “mini-stroke.” A TIA causes stroke-like symptoms for a short time because blood flow to the brain is temporarily blocked. Mayo Clinic explains that a TIA usually lasts only minutes and does not cause permanent damage, but it may be a warning sign of a future stroke.
Here are 10 subtle signs you should never ignore.
1. Sudden Weakness on One Side of the Body
One of the most important warning signs is sudden weakness or numbness in the face, arm, or leg, especially on one side. It may feel like heaviness, clumsiness, tingling, or loss of strength.
A person may suddenly drop a cup, struggle to lift one arm, drag one foot, or feel that one side of the face is not moving normally. Even if this lasts only a few minutes, it needs urgent medical attention.
This symptom is one of the classic stroke warning signs listed by the CDC and the American Stroke Association.
