Summary
Bipolar disorder patients show disrupted circadian rhythms, which mood stabilizers can improve. The Clock gene
Area of Science:
- Neuroscience
- Genetics
- Chronobiology
Background:
- Bipolar disorder is strongly associated with disrupted circadian rhythms.
- Mood stabilizer treatments can normalize these rhythms, correlating with patient recovery.
- The causal relationship between circadian abnormalities and bipolar disorder remains unclear.
Purpose of the Study:
- To explore the link between circadian rhythms, the Clock gene, and bipolar disorder.
- To discuss the potential biological mechanisms connecting circadian function and mood regulation.
Main Methods:
- Review of human genetic studies.
- Analysis of mouse behavioral studies.
- Examination of molecular biology advances in circadian gene characterization.
Main Results:
- Evidence suggests the Clock gene plays a significant role in bipolar disorder mood disruptions.
- Clock gene expression outside the suprachiasmatic nucleus (SCN) appears involved in mood regulation.
Conclusions:
- Circadian rhythm disruptions are a key feature of bipolar disorder.
- The Clock gene is implicated in the pathophysiology of bipolar disorder.
- Further research is needed to elucidate the precise mechanisms linking circadian biology to mood.

02:19Circadian Rhythms and Gene Regulation
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent years,...

01:30Bipolar Disorder
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.
01:28Human Genetics
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.

01:24Mania and Antimanic Drugs: Overview
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 a...
02:45Biological Clocks and Seasonal Responses
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.
