Hypersomnia Due to a Drug or Substance:
sleepiness due to the ingestion of over-the-counter or prescription medications, alcohol, caffeine, or recreational drugs. Sleepiness does not exist when the drug is not present. Some people with this problem find that they are sensitive to a medication, such as an antidepressant or allergy drug. Adjusting the dosage or type of medication may help. For many others, excessive napping, daytime drowsiness, and sleeping too long at night developed from abusing drugs. Excessive abuse of alchohol, sleeping pills or recreational drugs is the most common cause of this problem. (See also Drugs and Sleep.)

Hypersomnia Due to a Medical Condition: excessive tiredness caused by a medical illness. Sleepiness would not exist if the illness was not present. Many diseases make people tired. A few examples of severe conditions that cause people to sleep too much include: brain injury, Parkinson’s Disease, brain tumors, brain infections, kidney disease, Epstein-Barre Syndrome and neuro-muscular disease. It is essential that sleepiness is addressed by the doctor or specialist treating the underlying disease. If necessary, a sleep specialist may treat sleep-related symptoms as an additional problem. (See also Physical Illness and Sleep.)

Idiopathic Hypersomnia with Long Sleep Time: a disabling degree of daytime sleepiness despite nightly sleep time of 12 to 14 hours. Once awakened from nighttime sleep, drowsiness continues, leaving the person confused if not partially asleep, a state called sleep-drunkenness. Headaches and depression may also develop. It differs from narcolepsy, in which naps can be temporarily refreshing. Even naps of several hours do not refresh a person with Idiopathic Hypersomnia. It also differs from the disabling fatigue associated with illness. This disorder is very rare. Symptoms tend to begin gradually before age 30 and with few exceptions, does not change over time. Good sleep habits along with prescription medications to promote daytime wakefulness may provide some relief.

Idiopathic Hypersomnia without Long Sleep Time. like Idiopathic Hypersomnia with Long Sleep Time, a disabling degree of sleepiness. However, nighttime sleep lasts for only 8 to 10 hours. Drowsiness continues even after a full night’s sleep, leaving the person confused or partially asleep (sleep drunkenness). Headaches, dizziness, cold hands and feet, or depression may also develop. It differs from the tiredness of narcolepsy or excessive fatigue related to a medical condition. A rare condition, symptoms usually begin gradually before age 30 and with few exceptions, persist throughout life. A sleep specialist is best equipped to diagnose and treat both forms of Idiopathic Hypersomnia. Good sleep habits along with prescription medications to promote daytime wakefulness may provide relief.

Long Sleeper: the need for more nighttime sleep than most people need for their age group. Long sleepers need 10 to 12 hours of sleep per night. Sleep is refreshing but long enough to leave the person feeling as if they do not have enough time during the day. It may be difficult to keep up with the demands of school, job, or social activites. Long sleepers experience a lifelong pattern of longer sleep that remains stable throughout life. No treatment is needed. It is important to adapt to the body’s need for sleep.

Recurrent Hypersomnia: periods of excessive sleepiness that last for a few days to several weeks. Episodes arise anywhere from once to ten times per year. Sleep lasts for 16 to 18 hours per day. People with this disorder awaken only to eat and use the bathroom. Sleep is normal between attacks. Recurrent Hypersomnia differs from the need to catch up following a period of sleep deprivation. It also differs from other hypersomnias which occur consistently, such as Narcolepsy and Idiopathic Hypersomnia. Recurrent Hypersomnia follows extended periods of normal sleep. There are two forms of recurrent hypersomnia:
Klein-Levin Syndrome: which involves binge-eating, hyper-sexuality, and aggression. Patients often have a red face and sweat alot. This condition should be diagnosed and treated by a sleep specialist. Medications to promote wakefulness may help.
Menstrual-Related Hypersomnia: which develops just months after the first menstrual period and is related to a hormonal imbalance. Birth control pills may help.
