Sudden Weakness Or Numbness On One Side Of The Body

One of the most common signs of stroke is a sudden heavy, weak, or numb feeling in the face, arm, or leg, particularly on a single side. Most of them think that they are fatigued or thirsty, or that they are just having a short-run loss of energy. Yet, one-sided weakness is also a typical sign of brain stroke, and it should be addressed by the medical staff urgently. In case you find that you have some trouble lifting one arm or your face drooping, you might have a reason to suspect that there is some interrupted blood flow to the brain.

Slurred Or Difficulty Speaking

Difficulty in forming words, speech sounding as if he/she is pronouncing them in a foreign tongue, or just suddenly failing to comprehend some light sentences can be an early warning. Often people sweep this off to low blood sugar or stress. As a matter of fact, speech issues arise when the language of the brain parts is impaired. When the speech of a person suddenly becomes incomprehensible or discontinuous, it is necessary to consider this case a medical emergency.  Also Read - Winter Stroke Warning: How Cold Weather Affects Blood Pressure and Silently Increases Brain Stroke Risk

Sudden Severe Headache Without A Known Cause

A sudden, severe headache, which is usually referred to as the worst headache of my life, can be confused with a migraine or stressful headache. But this may mean that there is bleeding in the head (haemorrhagic stroke). In comparison to an ordinary headache, pain caused by a stroke can be sudden and can be accompanied by vomiting or dizziness, or even loss of vision.

Loss Of Balance Or Coordination

A sudden or mild headache, or walking in a straight line with a sense of dizziness or weakness, is often ignored as a symptom of general weakness or low blood pressure or vertigo. However, any sudden loss of coordination may be an indication of a stroke to the cerebellum, or the balance part of the brain. In case of dizziness that suddenly develops, it is important to seek prompt assessment along with other ailments.  Also Read - Winter Isn’t Just Flu Season, Cold Weather Also Raises Your Stroke Risk: Warns Neurologist

Sudden Vision Problems

Sudden impaired vision, the development of duplicate vision, or a total loss of vision may not necessarily lead to pain; hence, most people ignore it. Others will deny having screen strain or fatigue. Nonetheless, the vision may be altered whenever the blood flow to the visual centres of the brain is impaired.
