Narcolepsy is a sleep disorder characterized by inappropriate daytime attacks of sleep. It affects the part of the brain that manages sleep and wakefulness. A person suffering from this disorder can unpredictably fall asleep during the day. This illness begins in the second decade of a person's life and it continues on for the rest of their life. Along with fallin asleep during the day, some symptoms are frequent drowsiness and fragmented nighttime sleep.
Sleep disorders can also affect leg movements.
They both involve a lack of refreshing sleep and large amounts of irritating pain in the afflicted areas. Those with PLMS have no awareness of these movements, but those with RLS have an overwhelming urge to move their legs when resting. Both sleep disorders involving the movement of the legs distract the sufferer from adequate sleep. When people do these activities their biological clock is disrupted. This illness can last for a few to several days depending on the change of time zones and will adjust slowly day to day.
