Consider sleep paralysis when you feel pinned down and unable to move during sleep. Sleep paralysis is a neurological symptom that often occurs towards the end of sleep. When the sleep cycle is coming to an end, the person’s level of consciousness is basically awake, but the motor function of the limbs innervated by the cerebral cortex has not yet fully returned to normal, i.e., the level of consciousness is awake earlier than the recovery of the motor function of the limbs, so there is a short period of time in which the person is conscious, but feels that the limbs can not be moved. Sleep paralysis is often caused by excessive mental stress, excessive tension, and irregular work and rest. There may be other reasons for the symptom of feeling pressed and immobilized while sleeping. It is recommended that patients go to the Neurology Department of a regular hospital in a timely manner, except for the possibility of organic diseases. Under the guidance of a professional physician to clarify the cause of the disease and guide the treatment, so as not to delay the condition.
