Nearly 90% of patients with severe depression have early morning insomnia—meaning they wake up a few hours before scheduled and cannot return to sleep.
Insomina Due to Depression
Depression is characterized by sustained sadness severe enough to impair normal day-to-day functioning. It is influenced by psycho-social stressors, sleep deprivation, genetic factors, nutritional status, hormonal/chemical imbalance, alcohol and medication use, and multiple medical conditions.
The most common symptoms that accompany depression include some combination of the following: feelings of sadness, anxiety, emptiness, helplessness,pessimism,hopelessness, poor self-worth and excessive guilt, lack of pleasure, decrease energy, fatigue, concentration difficulties, changes in weight, suicidal thinking, and of course significant sleep disturbance.
Depressed patients are often more troubled by sleep problems than their sadness. They spend less time in deep, slow wave sleep (delta sleep). Nearly 90% of patients with severe depression have early morning insomnia—meaning they wake up a few hours before scheduled and cannot return to sleep. Insomnia is considered a major precursor to depression.
