I never cease to be amazed at the similarities of people from all over the world, every ethnicity, every country, and how small the world has become making it easier to learn about each other. I was recently in Kyoto, Japan, and was stopped on the street by a gentleman who wished to welcome me to his city. It turned out that he was educated in the U.S. at the same schools that I was. He had recently retired as Professor of English Language and Semantics at the University of Kyoto. As we spoke of many things, including medicine, he asked questions regarding sleeping pills, sleep disturbances, and alcohol relating to whether these represented character deficiencies and weaknesses (as one would consider when looking at most literature).
Actually, this is a very important topic. Despite the new development of sleep laboratories and sleep studies we know very little about the subject. Indeed, even the newest and most expensive of our tests is unable to predict when a person in a com...
Definition Sleep disorders in the elderly involve any disrupted sleep pattern, such as problems falling or staying asleep, too much sleep, or abnormal behaviors with sleep. Causes, incidence, and risk factors Sleep problems are common in the elderly. In general, older people need 30 to 60 minutes less sleep than younger people. Their sleep is less deep and more choppy than sleep in younger people. A healthy 70 year old may wake up four times during the night without it being due to disease. Some causes or contributors to sleep disturbances in older adults include: Alzheimer's disease Chronic disease, such as congestive heart failure Depression (depression is a common cause of sleep problems in people of all ages) Neurological conditions Pain caused by diseases such as arthritis Prescription drugs, recreational drugs, or alcohol Sedentary lifestyle Stimulants such as caffeine Urination at night
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.
