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.

- Promoting Evidence-Based Tobacco Cessation Treatment in Community Mental Health Clinics: Results of a Pilot Implementation Study: Promouvoir le traitement de sevrage tabagique fondé sur des données probantes dans les cliniques communautaires de santé mentale : résultats d'une étude pilote de mise en œuvreby Faith Dickerson on January 22, 2025
CONCLUSIONS: Clinicians at CMHCs were engaged by and participated in training and implementation activities around smoking cessation practices which they then delivered to a substantial portion of clients in their care. The results of this study provide important data for the future planning of testing implementation strategies to scale up tobacco cessation treatment in this population in outpatient mental health settings.
- Plastic but not progressive changes in cognitive function and hippocampal volume in an adolescent with bipolar disorder: a case reportby Bo Liu on January 22, 2025
Bipolar disorder (BD) is a prevalent mood disorder characterized by alternating episodes of depression and mania, often accompanied by varying degrees of cognitive impairment. Cognitive impairments often serve as indicators of a bleak prognosis or the likelihood of progressing to dementia. Additionally, some studies suggest that individuals diagnosed with BD may undergo a decline in hippocampal volume. However, the potential for reversibility of these changes, particularly in adolescents,...
- Poor self-reported sleep is associated with prolonged white matter T2 relaxation in psychotic disordersby Umit Haluk Yesilkaya on January 22, 2025
CONCLUSION: Our results highlight the connection between poor sleep and WM abnormalities in psychotic disorders. Future research using objective sleep measures and neuroimaging techniques suitable to probe free water is needed to further our insight into this relationship.
- Stem cell therapy for the treatment of psychiatric disorders: a real hope for the next decadesby Rosa Villanueva on January 22, 2025
In this review, it is evaluated the progress in the application of stem cell therapy to ameliorate the symptoms of bipolar disorder, major depression, schizophrenia, and autism. These disorders are highly prevalent in clinical medicine and are responsible for high levels of psychosocial disability among patients. All of them share common biomedical features, such as complex and variable genetic substrates, significant susceptibility to environmental changes, and insufficient knowledge of their...
