Will depression relapse after recovery? Can depression turn into mania?
Generally, depression may relapse after successful treatment, and certain types of depression may even evolve into mania. The specific outcome varies depending on individual differences and the type of depressive disorder. If concerned, it is advisable to seek medical consultation early. Detailed analysis is as follows:

If consolidation therapy is not consistently followed after depression treatment, if major life stressors occur (such as loss of a loved one or chronic stress), or if there is a family history of depression, the risk of relapse increases. Symptoms such as low mood and reduced interest may reappear, requiring timely monitoring of emotional changes and appropriate intervention.
If the depression is part of a bipolar disorder depressive episode rather than unipolar depression, during treatment (e.g., with antidepressants) or in the natural progression of the illness, it may shift into a manic state, characterized by elevated mood, increased energy, and impulsive behaviors. In such cases, doctors need to adjust the treatment plan to prevent symptom recurrence.
After depression treatment, it is essential to complete the recommended consolidation and maintenance therapy as prescribed. Maintaining regular daily routines and a healthy mental state, minimizing exposure to stressors, and promptly seeking medical evaluation for any significant emotional fluctuations can help prevent relapse or a switch into mania.
