Overview
Insomnia is a sleep disorder characterized by an inability to sleep and/or inability to remain asleep for a reasonable period. Insomniacs typically complain of being unable to close their eyes or "rest their mind" for more than a few minutes at a time. Both organic and nonorganic insomnia constitute a sleep disorder.[1][2].Insomnia is a medical term for a sleep disorder, in which a person have difficulty with falling asleep, staying asleep or feeling unfresh in the morning because of poor sleep[3].

Insomnia versus poor sleep quality
Poor sleep quality can occur as a result of sleep apnea or major depression. Poor sleep quality is caused by the individual not reaching stage 4 or delta sleep which has restorative properties. There are, however, people who are unable to achieve stage 4 sleep due to brain damage who still lead perfectly normal lives.
- Sleep apnea is a condition that occurs when a sleeping person's breathing is interrupted, thus interrupting the normal sleep cycle. With the obstructive form of the condition, some part of the sleeper's respiratory tract loses muscle tone and partially collapses. People with obstructive sleep apnea often do not remember awakening or having difficulty breathing, but they complain of excessive sleepiness during the day. Central sleep apnea interrupts the normal breathing stimulus of the central nervous system, and the individual must actually wake up to resume breathing. This form of apnea is often related to a cerebral vascular condition, congestive heart failure, and premature aging.
Major depression leads to alterations in the function of the hypothalamus and pituitary causing excessive release of cortisol which can lead to poor sleep quality.
Nocturnal polyuria or excessive nighttime urination can be very disturbing to sleep.[2] Nocturnal polyuria can be nephrogenic (related to kidney disease) or it may be due to prostate enlargement or hormonal influences. Deficiencies in vasopressin, which is either caused by a pituitary problem or by insensitivity of the kidney to the effects of vasopressin, can lead to nocturnal polyuria. Excessive thirst or the use of diuretics can also cause these symptoms.
