Introduction to Hypersomnia
Hypersomnia, or excessive sleepiness, is a condition in which a person has trouble staying awake during the day. People who have hypersomnia can fall asleep at any time; for instance, at work or while they are driving. They may also have other sleep-related problems, including a lack of energy and trouble thinking clearly.
According to the National Sleep Foundation, up to 40% of people have some symptoms of hypersomnia from time to time.
What Causes Hypersomnia?
There are several potential causes of hypersomnia, including:
- The sleep disorders narcolepsy (daytime sleepiness) and sleep apnea
(interruptions of breathing during sleep)
- Not getting enough sleep at night (sleep deprivation)
- Being overweight
- Drug or
alcohol abuse
- A head injury or a neurological disease, such as multiple sclerosis
- Prescription drugs, such as tranquilizers
- Genetics (having a relative with hypersomnia)
QUESTION
Why do we sleep? See AnswerHow Is Hypersomnia Diagnosed?
If you consistently feel drowsy during the day, talk to your doctor. In making a diagnosis of hypersomnia, your doctor will ask you about your sleeping habits, how much sleep you get at night, if you wake up at night, and whether you fall asleep during the day. Your doctor will also want to know if you are having any emotional problems or are taking any medications that may be interfering with your sleep.
Your doctor may also order some tests, including blood tests, computed tomography (CT) scans, and a sleep test called polysomnography. In some cases, an additional electroencephalogram (EEG), which measures the electrical activity of the brain, is needed.
How Is Hypersomnia Treated?
If you are diagnosed with hypersomnia, your doctor can prescribe various drugs to treat it, including stimulants, antidepressants, as well as several newer medications (for example, Provigil and Xyrem).
If you are diagnosed with sleep apnea, your doctor may prescribe a treatment known as continuous positive airway pressure, or CPAP. With CPAP, you wear a mask over your nose while you are sleeping. A machine that delivers a continuous flow of air into the nostrils is hooked up to the mask. The pressure from air flowing into the nostrils helps keep the airways open.
If you are taking a medication that causes drowsiness, ask your doctor about changing the medication to one that is less likely to make you sleepy. You may also want to go to bed earlier to try to get more sleep at night, and eliminate alcohol and caffeine.

Cancer
Cancer is a disease caused by an abnormal growth of cells, also called malignancy. It is a group of 100 different diseases, and is not contagious. Cancer can be treated through chemotherapy, a treatment of drugs that destroy cancer cells.
CAT Scan
A CT scan is an X-ray procedure that combines many X-ray images with the aid of a computer to generate cross-sectional and three-dimensional images of internal organs and structures of the body. A CT scan is a low-risk procedure. Contrast material may be injected into a vein or the spinal fluid to enhance the scan.
EEG - Electroencephalogram
An Electroencephalogram also called an EEG, is a test that can help diagnose epilepsy. The electrical signals of the brain are recorded during an EEG. This electrical activity is detected by electrodes or sensors, placed on the patient's scalp and transmitted to a polygraph that records the activity. Electrical signals produced by the brain neurons are picked up by the electrodes and transmitted to a polygraph, where they produce separate graphs on moving paper using an ink writing pen or on a computer screen.
Genetic Disease
The definition of a genetic disease is a disorder or condition caused by abnormalities in a person's genome. Some types of genetic inheritance include single inheritance, including cystic fibrosis, sickle cell anemia, Marfan syndrome, and hemochromatosis. Other types of genetic diseases include multifactorial inheritance. Still other types of genetic diseases include chromosome abnormalities (for example, Turner syndrome, and Klinefelter syndrome), and mitochondrial inheritance (for example, epilepsy and dementia).
Head Injury
In the United States, head injuries are one of the most common causes of death and disability. Head injuries due to bleeding are generally classified by the location of the blood within the skull, these include:
- epidural hematoma,
- subdural hematoma,
- subarachnoid bleed,
- intracranial bleed,
- sheer injury, edema, and
- skull fracture.
Some common symptoms of a head injury include:
- vomiting,
- bleeding from the ear,
- speech difficulties,
- paralysis,
- difficulty swallowing, and
- body numbness.
Treatment of a head injury depends on the type and severity of the injury.
MRI Scan
MRI (or magnetic resonance imaging) scan is a radiology technique which uses magnetism, radio waves, and a computer to produce images of body structures. MRI scanning is painless and does not involve X-ray radiation. Patients with heart pacemakers, metal implants, or metal chips or clips in or around the eyes cannot be scanned with MRI because of the effect of the magnet.
Multiple Sclerosis (MS)
Multiple sclerosis or MS is an autoimmune disorder in which brain and spinal cord nerve cells become demyelinated. This damage results in symptoms that may include numbness, weakness, vertigo, paralysis, and involuntary muscle contractions. Different forms of MS can follow variable courses from relatively benign to life-threatening. MS is treated with disease-modifying therapies. Some MS symptoms can be treated with medications.
Obesity (Weight Loss)
Obesity is the state of being well above one's normal weight. A person has traditionally been considered to be obese if they are more than 20% over their ideal weight. That ideal weight must take into account the person's height, age, sex, and build.
Premenstrual Dysphoric Disorder (PMDD)
Premenstrual dysphoric disorder (PMDD) is considered a severe form of premenstrual syndrome (PMS). PMDD has also been referred to as late luteal phase dysphoric disorder. The cause of PMDD is unknown. Some of the common symptoms of PMDD (not an inclusive list) include mood swings, bloating, fatigue, headache, irritability, headache, breast tenderness, acne, and hot flashes.
Treatment for PMDD is with medication to treat the symptoms of PMDD.
Sleep Apnea
Sleep apnea is defined as a reduction or cessation of breathing during sleep. The three types of sleep apnea are central apnea, obstructive apnea (OSA), and a mixture of central and obstructive apnea. Central sleep apnea is caused by a failure of the brain to activate the muscles of breathing during sleep. OSA is caused by the collapse of the airway during sleep. OSA is diagnosed and evaluated through patient history, physical examination and polysomnography. There are many complications related to obstructive sleep apnea. Treatments are surgical and non-surgical.
