Insomnia Vernon - The definition of insomnia is the report of a person's trouble in sleeping. Sufferers of insomnia would usually respond "yes" to these next questions, "Do you have trouble staying or falling asleep?" and "Do you experience problems sleeping?" The word of insomnia is often used in sleep literature to be able to describe a disorder which is proven by interrupted sleep.
Insomnia is often believed to be a symptom and a sign which can accompany some medical, sleep and psychiatric disorders. It is normally characterized by poor quality of sleep or persistent problem falling asleep or staying asleep. Normally, due to insufficient rest, insomnia is usually followed by functional impairment whilst awake. One definition of insomnia is "difficulties maintaining or initiating sleep." Non-restorative sleep is one more factor and is associated with marked distress and poor sleeping for a month and impairments in daytime functioning.
There are three main categories which Insomnia could be grouped, comprising: primary and secondary or co-morbid insomnia. Primary insomnia refers to a sleep disorder that is not resulting from whatever psychiatric, medical or environmental reason. A complete diagnosis is considered necessary in order to distinguish between: insomnia as secondary to a different condition, primary insomnia co-morbid with one or more conditions and free-standing primary insomnia.
Transient insomnia is defined as lasting less than one week. This may be caused by severe depression, changes in sleep environment, timing of sleep, stress or by a different illness. The major effects of transient insomnia are impaired psychomotor performance and drowsiness, similar to those of sleep deprivation.
Acute insomnia is the inability to consistently sleep for a time period of less than a month, while chronic insomnia usually lasts for longer than one month. Chronic insomnia can be a primary condition or it could be caused by a different sickness. The effects can vary according to its reasons and can include muscular exhaustion, mental exhaustion and hallucinations. Some individuals who suffer from this disorder describe things as almost taking place in slow motion, as though objects seem to blend together and causing double vision.
