Unconsciousness is a state where a person appears to be in deep sleep from

where he/ she cannot be awoken. The individual does not respond to any

external stimuli, like sprinkling cold water on the face, and for that matter

even painful ones like piercing with a pin, tingling a nerve etc. This insensible

state is brought about by some interference in the normal functioning of the

brain and the nervous system.

Unconsciousness when partial is called stupor and when complete is called

coma. In cases of stupor, the individual can be roused with difficulty but the

eyelids cannot be opened due to resistance by the individual. In a coma,

however there is no response when an individual is being called, the lid can

be opened without any resistance.

The usual case of unconsciousness includes fainting, sunstroke, concussion

(brain injury), etc. Fainting is caused by the temporary reduction in the blood

supply to the brain because of fright, unexpected good or bad news etc.

People held up in stuffy places like the elevators often faint. A sudden fall inblood pressure can also cause fainting. The individual appears pale, becomes

weak and slow, breathing becomes shallow and skin turns cold and clammy.

Excessive summer heat can make the individual faint. Prolonged exposure to

sun may cause sunstroke, which starts with headache, vomiting, dizziness,

cramps or dryness of the throat.

Concussion commonly results in unconsciousness. Direct injury to the brain

caused by either a blow on the head or a fall from a height etc may result in

concussion. The patient may ‘black out’ for a short time. An individual could

suddenly become unconscious due to a heart attack. The initial signs are

vomiting, profuse sweating and pain on the left side of the chest.
