Sleep Disorders are characterized by not being able to fall asleep, frequent waking, or sleep apnea. Dr. Jay Tarnow, in an article, ADHD and Sleep Disorders , that appeared on the website ADDA-SR , listed possible causes of sleep disturbances as, “a symptom of a disorder (i.e. ADHD, Depression, Anxiety Disorders ), a side effect to medication (e.g. stimulants), lifestyle induced (i.e. caffeine, alcohol, obesity), or a primary sleep disorder.” Not getting enough sleep at night can cause mood swings, hyperactivity, inattention, impulsiveness, lack of motivation, aggressiveness, headaches and slower reaction times. Many of these symptoms also appear in ADHD.

Sleep Disorders vary in nature and degree. The three major sleep disorders are dyssomnias ( insomnia ), hypersomnia (disorders of excessive sleepiness) and parasomnias (abnormal behaviors during sleep). Sleep consists of two distinct states: REM (rapid eye movement) sleep and NREM (non-REM) sleep. Dreaming occurs mostly in REM sleep.

Irregular sleep-wake syndrome is sleeping without any real schedule.
Sleep-wake syndrome - irregular
Causes, incidence, and risk factors
Some people have an irregular sleep-wake pattern because of a problem with brain function, the body's internal clock (circadian pacemaker), or other reasons.
This disorder is very uncommon. It typically occurs in someone with a brain dysfunction who does not have a regular routine during the day. The amount of total sleep time is normal, but the body clock loses its normal circadian cycle.
Similar symptoms may be seen in people who have frequently changing work shifts and in travelers who often change time zones. These people have a different condition, such as shift work sleep disorder or jet lag syndrome.
