Bipolar Disorder
A disorder associated with episodes of mood swings ranging from depressive lows to manic highs.
The exact cause of bipolar disorder isn’t known, but a combination of genetics, environment, and altered brain structure and chemistry may play a role.
Manic episodes may include symptoms such as high energy, reduced need for sleep, and loss of touch with reality.
Depressive episodes may include symptoms such as low energy, low motivation, and loss of interest in daily activities. Mood episodes last days to months at a time and may also be associated with suicidal thoughts.
Treatment is usually lifelong and often involves a combination of medications and psychotherapy.

- Mood instability and risk of gastrointestinal diseases - a univariable and multivariable mendelian randomization studyby Rui-Lin Liu on December 20, 2024
CONCLUSION: This study provides compelling evidence for a potential causal relationship between mood instability and certain gastrointestinal diseases underscoring the importance of considering mood instability as a potential risk factor for gastrointestinal diseases as well as the positive role of maintaining mood stability in the prevention of gastrointestinal disorders.
- The emerging role of long non-coding RNA SOX2-OT in cancers and non-malignant diseasesby Jingjie Yang on December 20, 2024
SOX2 overlapping transcript (SOX2-OT) is a long non-coding RNA located at chromosome 3q26.33 in humans. Convincing data confirm that SOX2-OT is evolutionarily conserved and plays a significant role in various malignant and non-malignant diseases. In most cancers, the upregulation of SOX2-OT acts as an oncogenic factor, strongly correlating with tumor risk, adverse clinicopathological features, and poor prognosis. Mechanistically, SOX2-OT is regulated by seven transcription factors and influences...
- Error monitoring and response inhibition in adolescents with bipolar disorders: An ERP studyby Kasey Stack on December 20, 2024
Cognitive control develops throughout adolescence, a high-risk period for bipolar disorders (BD) onset. Despite neurobehavioral abnormalities in adults with BD, there is minimal research investigating deviations in cognitive control in adolescents with BD. Cognitive control involves numerous processes. Identifying the specific neural abnormalities in adolescent BD could provide precise targets for novel interventions that improve illness outcomes. The present study administered a Go/No-Go (GNG)...
