The average spell of clinical depression, if left entirely untreated, will last around 8 months. During a depression, the sufferer will normally be convinced that it will never go away, but this is a classic feature of the way depression makes us think.
In chronic depression, they last at least two years. Because chronic depression tends to be more severe than episodic depression, treatment is also more intensive. Several subtypes of chronic depression exist, but they have similar long-term effects on health and quality of life.elapse is also a challenge. About half of patients with chronic depression who respond to treatment (whether with antidepressants, psychotherapy, or a combination of the two) will suffer a relapse within one to two years if they stop treatment. For that reason, some type of maintenance therapy may be necessary.
