Isolated sleep paralysis

Isolated sleep paralysis is a type of paralysis that occurs with a sleep disorder. Sleep paralysis is the inability to perform voluntary muscle movements during sleep.


Episodes of isolated sleep paralysis last from a few seconds to 1 or 2 minutes in which the person is unable to move or speak. These spells end on their own or when the person is touched or moved. In rare cases, the person may have dream-like sensations or hallucinations, which may be scary to them.

Exams and Tests

If you do not have other symptoms of narcolepsy, there is usually no need to have sleep studies done.


In most cases, isolated sleep paralysis occurs so rarely that treatment is not needed. If the cause is known, for example due to lack of sleep, correcting the cause, such as getting enough sleep, often resolves the condition.

In persons with mental health conditions, medication and behavioral therapy (talk therapy) to help treat the mental condition may also resolve sleep paralysis.
