What is a clinical manifestation of Major Depressive Disorder?

A clinical manifestation of Major Depressive Disorder often includes altered sleep patterns, which can take the form of insomnia (difficulty sleeping) or hypersomnia (sleeping excessively). These changes in sleep are significant because sleep disturbances are frequently reported by individuals with depression, impacting their overall mood, energy levels, and ability to function in daily life. The relationship between mood disorders and sleep is complex, and alterations in sleep can serve as both a symptom and a contributing factor to the severity of depression.

In contrast, increased energy levels, consistent happiness, and improved concentration are not typically associated with Major Depressive Disorder. Instead, individuals with this condition often experience tiredness, a lack of motivation, feelings of sadness, and difficulties with focus and concentration. Therefore, altered sleep patterns accurately reflect a key clinical feature of the disorder.
