The condition you are describing is known as "unipolar depression" or "major depressive disorder (MDD)" with recurrent episodes. In unipolar depression, individuals experience cycles of depression without the presence of mania or hypomania. The mood swings in unipolar depression are limited to depressive episodes, and individuals typically return to a "normal" mood state in between these episodes.
Here are some key points about unipolar depression:
No Mania or Hypomania: Unlike bipolar disorder, individuals with unipolar depression do not experience the characteristic manic or hypomanic episodes.
Recurrent Depressive Episodes: People with unipolar depression have recurring episodes of major depressive symptoms, which can include persistent sadness, loss of interest in activities, changes in appetite or sleep patterns, feelings of worthlessness or guilt, difficulty concentrating, and thoughts of death or suicide.
Stable Mood Between Episodes: In contrast to bipolar disorder, where individuals experience distinct periods of elevated or irritable mood, people with unipolar depression typically return to a more "normal" mood state in between depressive episodes.
Duration and Severity: Depressive episodes in unipolar depression can vary in duration and severity. Some episodes may be relatively brief and less severe, while others can be more prolonged and intense.
Treatment: Treatment for unipolar depression often involves psychotherapy (such as Cognitive Behavioral Therapy) and/or medication, such as antidepressants. The goal is to reduce the frequency and intensity of depressive episodes and improve the individual's overall quality of life.
It's important to note that diagnosing and managing mental health conditions is a complex process, and a thorough evaluation by a qualified mental health professional is necessary to accurately diagnose unipolar depression or any other mood disorder. If you or someone you know is experiencing symptoms of depression, it's essential to seek help from a healthcare provider to receive proper assessment and support.
