Depression is a common mental disorder that presents with some or all of the following symptoms: a depressed mood, a loss of interest in things that once brought pleasure, feelings of guilt or low self-worth, disturbed sleep patterns, changes in appetite, a lack of energy, and poor concentration. These symptoms lead to impairments in an individual’s ability to take care of his or her everyday responsibilities and can become chronic or recurrent.
