Because each type of depression is different, the severity of symptoms and how persistent they are can vary from patient to patient. The main types of depression are major depression or unipolar depression, chronic depression or psychosis, and manic depression or bipolar depression. Besides the main types of depression, there are subtypes of these disorders. Since different types of depression have completely different effects on each person, treatments must also be individualized.
With major depression, the symptoms are similar to those of depression, but they are more intense than the symptoms of normal depression. These symptoms will interfere with the individual's daily activities. Work, study, eating and sleeping habits may be disrupted. The person will not be able to gain any pleasure from his previous activities. The depressive episodes of major depression can be debilitating and the quality of life becomes markedly worse.
In major depression, episodes may be single or recurrent. A single episode will disappear after the treatment takes effect. For recurrent major depression, there will be a major depressive episode followed by a depressive episode. These depressive episodes are probably followed by a few years of normal depression-free life. Attacks can then occur without any warning.
Chronic depression is less severe than major depression or bipolar depression. Symptoms are lifelong. A person with chronic depression can still go on with their life without any interference from the symptoms. Individuals are more likely to suffer from dual depression. Dual depression is a mixture of chronic depression and major depression.
Bipolar depression is not as common as other types of depression. The mood swings of this depression are cyclical in nature. Meaning, there are periods of euphoric highs and sad, worthless lows. There are times when mood swings are rapid and dramatic. Symptoms of bipolar depression include hyperactivity, having unlimited amounts of energy, loss of good judgment, feeling invincible, among others.
All types of depression react differently in different people. Each of these symptoms of depression needs proper treatment. Therefore, you should see your doctor to get a diagnosis of depression and start treatment.
