Depression can be defined as a mental state that is characterized by an attitude that is pessimistic and melancholic with a lack of mental and physical activity. When a person suffers from depression, there is a reduced amount of neurotransmitters located in the parts of the central nervous system of a person.
The depression also implies that the nervous system does not function properly due to this stimulation from neurotransmitters. With the deficiency serotonin and adrenalin, the nerve cells that send impulses to the other nerve cells, there is reduced activity in the brain that causes slowness in certain parts of the brain and this leads to depression.
The depression also relates to the deficiency of gamma amino butyric acid or GABA. When there is a reduced amount or lack of GABA in the brain, there is a slow response of some nerve impulses that result in anxiety and panic response. There are also other different types of depressive mechanisms that are involved in the process. They vary from person to person and they also influence the nature and the severity of depression.
The depression and its effects should be addressed at the earliest when the symptoms are experienced in a person. A depressed person does not have an interest in normal activities and tends to shun all kinds of social interaction. There is loss of sleep and appetite. The person desires to be left alone and isolated. There are negative emotions and an intense pessimism towards life and people.
There is a tendency to feel that the person is hopeless and does not have the desire to live. The depression definition can also induce a person to self injury and suicide. There are both natural and medical cures and remedies for depression and once a person falls prey to it, he/she should resort to them immediately.
