Insomnia is divided into two types and each has distinct but overlapping causes.
Transient, short-term insomnia is a common type of sleep disturbance. Most patients do not seek medical help and recover naturally; though in some individuals the condition may become chronic. Stress, related to health, occupational, financial, academic or interpersonal issues, is often the underlying cause. Working night shifts, or jet lag, may be other precipitating factors.
Chronic insomnia has many causes.
Psychiatric illness is the most common factor.
Chronic insomnia is also considered a risk factor for the development of mood disorders/other psychiatric illnesses.
Underlying medical disorders-virtually any health condition may deprive you of sleep.
Sleep-wake schedule disorder, including that caused by jet lag and shift - work
Other primary sleep disorders, such as restless legs syndrome and sleep apnoea
Primary insomnia, which has no identifiable cause
Sleep patterns also change with aging. Some of these disturbances may be a function of the aging process itself, rather than resulting from secondary factors.
