When life sucks

Insomnia – Just saying…

Insomnia – Wikipedia, the free encyclopedia.

Insomnia (or sleeplessness) is an individual’s reported sleeping difficulties.[1] While the term is sometimes used in sleep literature to describe adisorder demonstrated by polysomnographic evidence of disturbed sleep, insomnia is often defined as a positive response to either of two questions: “Do you experience difficulty sleeping?” or “Do you have difficulty falling or staying asleep?”[1]

Thus, insomnia is most often thought of as both a sign and a symptom[1][2] that can accompany several sleep, medical, and psychiatric disorders, characterized by persistent difficulty falling asleep and/or staying asleep or sleep of poor quality. Insomnia is typically followed by functional impairment while awake. One definition of insomnia is “difficulties initiating and/or maintaining sleep, or nonrestorative sleep, associated with impairments of daytime functioning or marked distress for more than 1 month.”[3] Insomnia can occur at any age, but it is particularly common in the elderly.[4]. Insomnia can be short term (up to three weeks) or long term (above 3-4 weeks) which can unfortunately lead to memory problems, depression, irritability and an increased risk of heart disease and automobile related accidents [5].
Insomnia can be grouped into primary and secondary, or comorbid, insomnia.[6][7][8] Primary insomnia is a sleep disorder not attributable to a medical, psychiatric, or environmental cause.[9] It is described as a complaint of prolonged sleep onset latency, disturbance of sleep maintenance, or the experience of non-refreshing sleep.[10] A complete diagnosis will differentiate between:

  • insomnia as secondary to another condition,
  • primary insomnia co-morbid with one or more conditions, or
  • free-standing primary insomnia.
