Depression is the most unpleasant experience a person can endure. It is far more difficult to cope with than a physical ailment. The growing complexities of modern life and the resultant crisis, as well as mental stress and strain in day to day living, usually leads to this disorder. It also arises out of the monotony and drudgery of a daily routine, without any meaningful variation in urban life. Suicide is the major risk in extreme cases of depression.
Symptoms
It is not always easy to diagnose depression clinically. The most striking symptoms of depression are feelings of acute sense of loss and inexplicable sadness, loss of energy and loss of interest. The patient usually feels tired and lacks interest in the world around him. Sleep disturbance is frequent. Usually the patient wakes up depressed at 4 or in the morning and is unable to return to sleep. Other disturbed sleep patterns are difficulty in getting off to sleep on going to bed at night, nightmares and repeated waking from midnight onwards.
ADVERTISEMENTS:
The patient often suffers from guilty, oppressive feelings and self-absorption. Other symptoms of depression are: loss of appetite, giddiness, itching, nausea, agitation, irritability, impotence or frigidity, constipation, aches and pains all over the body, lack of concentration and lack of power of decision. Some persons may lose interest in eating and suffer from rapid loss of weight while others may resort to frequent eating and as a result gain in weight.
Cases of severe depression may be characterized by low body temperature, low blood pressure, hot flushes and shivering. The external manifestations represent a cry for help form the tormented mind of the depressed persons. The severely depressed patient feels worthless and is finally conceived that he himself is responsible for his undoing and his present state of helpless despair.
