Enumerate about the diseases Insomnia

The results from studies of people, who claim that they do not sleep, or wake up frequently from sleep show that their insomnia can have many causes. Nevertheless, systematic recordings of EEGs from poor sleepers before and during sleep show that the sleepers exaggerated the length of time that it took them to get to sleep. But poor sleepers do have decreased dream sleep, move more during sleep, and go through more transitions between sleep stages than normal people do. Moreover, when awakened from slow-wave sleep, they claim that they have not been sleeping. Insomnia may be associated with nightmares and night terrors  sleep apnea (arrested breathing during sleep), restless legs syndrome (RLS, described in the Snapshot below), myoclonus (involuntary muscle contraction), the use of certain kinds of drugs, and certain kinds of brain damage.
