Insomnia Overview

Most adults have experienced insomnia or sleeplessness at one time or another in their lives. An estimated 30-50% of the general population are affected by insomnia, and 10% have chronic insomnia.
Insomnia is a symptom, not a stand-alone diagnosis. By definition, insomnia is "difficulty initiating or maintaining sleep, or both." Although most of us know what insomnia is and how we feel and perform after one or more sleepless nights, few seek medical advice. Many people remain unaware of the behavioral and medical options available to treat insomnia.

Insomnia affects all age groups. Among older adults, insomnia affects women more often than men. The incidence increases with age.
Stress most commonly triggers short-term or acute insomnia. If you do not address your insomnia, however, it may develop into chronic insomnia.

Insomnia may result from either psychological or physical causes:
  • The most common psychological problems include anxiety, stress, and depression. In fact, insomnia may be an indicator of depression. Many people will have insomnia during the acute phases of a mental illness.
  • Physiological causes span from circadian rhythm disorders, sleep-wake imbalance, to a variety of medical conditions. Following are the most common medical conditions that trigger insomnia:
    • Chronic pain syndrome
    • Congestive heart failure
    • Chronic obstructive pulmonary disease (COPD)

  • Certain medications have been associated with insomnia. Among them are certain over-the-counter cold and asthma preparations
    • The prescription varieties of these medications may also contain stimulants and thus produce similar effects on sleep.
    • Medications for high blood pressure have also been associated with poor sleep.
  • Common stimulants associated with poor sleep include caffeine and nicotine. You should consider not only restricting caffeine use in the hours immediately before bedtime but also limiting your total daily intake.
  • People often use alcohol to help induce sleep, as a nightcap. However, it is a poor choice. Alcohol is associated with sleep disruption and creates a sense of unsatisfactory sleep in the morning.
  • A disruptive bed partner with loud snoring or periodic leg movements also may impair your ability to get a good night's sleep.

Causes

Hypersomnia is a condition that has many different factors to it may occur. Some causes of hypersomnia could be from drug or alcohol abuse, heredity, the side effects of medication, and it can also be caused by autonomic nervous system dysfunction. Since the autonomic nervous system is responsible for regulating the physiologic processes of the human body, if an imbalance occurs, such as for one's blood pressure, this can eventually lead to hypersomnia.Another reason that hypersomnia may occur, relating to the central nervous system is through head trauma. When this type of injury takes place, the central nervous system is injured in a situation like this, and as a result, hypersomnia may occur Different people are more likely to hypersomnia that will be listed below.

Amphetamine, methyphenidate, and modafinil are some of the stimulants that will often be prescribed by from a doctor. Other drugs that will help treat hypersomnia are clonidine, levodopa, bromocriptine, antidepressants, and monoamine oxidase inhibitors. Although drugs in many cases can be used to help treat hypersomnia a different approach could be much more useful to another individual. For example, someone who is obese, which is a cause of hypersomnia may treat the condition by simply losing weight. Patients should also avoid the consumption of alcohol and coffee. Late night outings should often be avoided.
