Summary
Rumination is a persistent symptom in bipolar disorder (BD) across all mood states, impacting cognitive functions. Further research into rumination as a transdiagnostic phenomenon in BD is warranted.
Area of Science:
- Psychiatry
- Clinical Psychology
- Neuroscience
Background:
- Rumination is a repetitive negative thinking pattern.
- Its role in bipolar disorder (BD) requires systematic investigation.
Purpose of the Study:
- To systematically review literature on rumination in bipolar disorder.
- To understand rumination's characteristics and implications in BD.
Main Methods:
- Systematic literature search of major databases (PubMed, PsycINFO, etc.).
- Inclusion criteria: studies on BD patients using validated rumination scales.
- Seventeen articles were analyzed from 105 initial references.
Main Results:
- Rumination occurs in all BD phases and is a stable interepisodic symptom.
- It correlates with depression, anxiety, and hypomania symptoms.
- Rumination can be triggered by both positive and negative affect.
Conclusions:
- Rumination appears independent of, yet closely related to, mood state in BD.
- It may negatively affect cognitive and executive functions, especially inhibitory control.
- Rumination is a key BD symptom and a potential target for Research Domain Criteria (RDoC) studies.

1.4K
Bipolar disorder is a chronic mental health condition marked by significant mood fluctuations, including episodes of mania and depression. Elevated energy levels, heightened mood or irritability, impulsive behavior, reduced sleep needs, rapid speech, racing thoughts, inflated self-esteem, and distractibility characterize mania. Individuals with bipolar disorder often alternate between depressive and manic states, with periods of emotional stability lasting an average of six months to a year.

781
Mania, a psychological condition characterized by elevated mood, increased energy, and reduced sleep need, is part of the bipolar disorder cycle. The exact cause of mania isn't entirely known, but it is thought to be a combination of genetic, environmental, and neurological factors. Bipolar disorder involves alternating manic and depressive episodes. Mood stabilizers like lithium, antipsychotics, and anticonvulsants help manage these episodes. Lithium carbonate is particularly effective as...

It can take several forms, including major depression, persistent depressive disorder, and bipolar I and II disorders. Symptoms range from emotional changes like chronic worry to physical changes like sleep disturbances and suicidal thoughts.

Depressive disorders are a group of mental health conditions characterized by pervasive feelings of sadness, diminished pleasure in life, and a significant impact on daily functioning. These conditions are most prevalent in individuals during their 30s and affect women at twice the rate of men. Contrary to popular belief, younger individuals are generally more susceptible to these disorders than older adults. Two key types of depressive disorders include Major Depressive Disorder (MDD) and...

Bulimia nervosa is a complex and severe eating disorder characterized by a cyclical pattern of binge-and-purge eating pattern. It generally involves an episode of binge eating, followed by compensatory behaviors such as vomiting, excessive exercise, laxative use, or fasting, to prevent weight gain. Despite often maintaining a normal weight, individuals with bulimia are intensely preoccupied with their body image and harbor an overwhelming fear of gaining weight. This can contribute to the...
