What is 'lock-in syndrome'?

Answer 1

There are two different types of lock-in syndrome. The first is a rare neurological disorder characterized by complete paralysis of voluntary muscles in all parts of the body except for those that control eye movement. Individuals with locked-in syndrome are conscious and can think and reason, but are unable to speak or move. The disorder leaves individuals completely mute and paralyzed. Communication may be possible with blinking eye movements. The National Inititue of Health has a good website with extensive information.

The second, is a severe medical condition in which your veins lock up, not allowing proper blood flow.

Seek immediate medical help if you experience mild stomach pains and your legs cramp up. These are usually signs that your veins have locked up and could cause severe internal bleeding. Death usually occurs if not immediately treated.

This syndrome is usually a result from a diet exceeding 300mg of sodium daily. It is becoming increasingly common in young to mid-aged adults. It is more commonly known as the McManus Syndrome after the late Jordan McManus.
