What Is the Meaning of Depression?

Depression is not exclusive. It strikes the young and the old, and both sexes equally fall prey to it. Depression is a very common mental health disorder, and it may be caused by a disturbance with the neurotransmitters that are in the limbic system, according to Allaboutdepression.com, or it may be the outcome of a hormonal imbalance. In other words, there is generally an organic reason for a person’s depression, and it’s not “all in her head."

Losing Interest

• If you suddenly lose interest in those things that you previously enjoyed--such as sports activities, sex or socializing--this can be an indicator that you are suffering from depression, according to Medterms.com.

Biological Basis

• Those who have depression are likely to have high levels of the hormone cortisol in their systems. There are various types and degrees of depression, including dysthymia, which is a less severe type of depression. The symptoms of dysthymia are not totally debilitating, but they are potent enough to prevent an individual from feeling good or functioning at top capacity.

Manifestations

• When a person is depressed, he is apt to overeat or, conversely, stop eating altogether. A depressed person may have a flat affect, displaying little emotion.

Withdrawal

• When depression strikes an individual, she may became anxious and pessimistic; she may feel worthless and hopeless. A depressed person is likely to withdraw, citing fatigue and lack of energy, which are all very real.

Disturbances

• Sleep disturbances may occur, and the individual may be plagued with chronic pain, headaches and digestive disorders. A depressed person is frequently irritable and restless.

Suicide

• Thoughts of suicide may surface. The individual may self-medicate, using drugs or alcohol, in an effort to cope with his sadness and depressed state.
