There are many people that have an undiagnosed sleep disorder. They may feel very sleepy during the day. They may have trouble falling to sleep or staying asleep. Friends or relatives may tell them they look very tired. They may experience mood changes, irritability or become overly emotional. Often they have difficulty paying attention, concentrating, or remembering things that are important. These are all symptoms of sleep deprivation, and possibly of a sleep disorder.
When someone says “I can’t fall asleep” it can mean several things.
Many people have the problem of not being able to fall asleep when they go to bed. This is called sleep latency.
Sleep latency can be a very serious symptom of certain sleep disorders, including sleep onset insomnia, delayed sleep phase disorder, shift work, restless leg syndrome or paradoxical insomnia. Many times the problem is not being able to stay asleep, which is sleep fragmentation. Often a person with this complaint can fall to sleep easily when they go to bed, but wake up often throughout the night.
Sleep disorders may include sleep maintenance insomnia, shift work.
If a person wakes up very early in the morning and cannot get back to sleep, it could be a sign of advanced sleep phase disorder or sleep maintenance insomnia.
Those that say “I can’t get up in the morning” and take an hour or more to fully wake from their sleep may suffer from excessive sleep inertia.
They are having difficulty making the transition from sleep to being awake. Sleep disorders that could be responsible for excessive sleep inertia are sleep apnea and delayed sleep phase disorder.
A person that answers the question with “I do strange things in my sleep” may find that their sleep is full of surprises. Sleepwalking, Sleep terrors, confusional arousals, REM sleep behavior disorder, nightmares, sleep-related eating disorder and bruxism are all types of sleep disorders known as parasomnias.
