Novel biomarkers for bipolar disorder

Area of Science:

• Neuroscience
• Psychiatry
• Biomarker Discovery

Background:

• Bipolar disorder traditionally viewed as an affective disorder.
• Reconceptualized as a multisystem disease impacting mood, cognition, metabolism, and sleep.
• Focus on identifying biomarkers for understanding pathophysiology and disease course.

Purpose of the Study:

• To review circulating peripheral and neuroimaging biomarkers for bipolar disorder.
• To synthesize current knowledge on potential biological markers.
• To explore the utility of biomarkers in diagnosing and monitoring bipolar disorder.

Main Methods:

• Literature review of circulating peripheral and neuroimaging biomarkers.
• Consideration of neurotrophic factors, immune parameters, oxidative stress, and hormones.
• Analysis of neuroimaging findings in relation to bipolar disorder.

Main Results:

• Biomarker research in bipolar disorder is a rapidly developing field.
• Current evidence indicates that no single biomarker can capture the disorder's complexity.
• A combination of biomarkers shows promise for clinical application.

Conclusions:

• A composite biomarker approach, including neurotrophic factors, cytokines, and oxidative stress molecules, is promising.
• This approach may aid in identifying altered mood states and neuroprogression.
• Further research is needed to validate these findings and develop clinical tools.
