Depression
Depression is a chronic, long-lasting or recurring and treatable disorder, where the patient experiences sadness, worthlessness, loss of motive, loss of interest and/or hopelessness.
A depressive disorder is an illness that involves the mood and thoughts and in simple words can be expressed as persistent sad mood. Depression is not a character flaw or a sign of personal weakness and the suffering person can’t make himself well by trying to snap out of it. Depression affects the way a person eats and sleeps, the way one feels about oneself, and the way one thinks about things.
Depression results from a complex partly understood biochemical changes in the brain, which are influenced and supported by multiple causes inclusive of the genetic trait, circumstantial factors, hormonal factors, socio-personal reasons, etc. Increased levels of brain chemicals called neurotransmitters, such as serotonin and norepinephrine are found to improve the state of depression.
