A mutation in a gene associated with circadian rhythm extends the clock period, causing people to stay up late at night and sleep late in the mornings.
Researchers report sleep disruptions may not only be a symptom of neurological diseases, circadian rhythm disruptions may drive the brain pathology that contributes to anxiety, dementias and other disorders.
Researchers have found an association between the Per2 gene and breast cancer. The Per2 gene plays an important role in both the body's circadian clock and mammary gland development.
UT Southwestern researchers discover a gene implicated in circadian rhythm may also play a vital role in regulating genes important for our brain evolution.
A protein associated with circadian rhythm appears to play a significant role in some forms of epilepsy, researchers say.
A new study reports depressed people who responded to ketamine found their activity increased during earlier parts of the day. Researchers suggest clock gene machinery may be linked to the type of depression that responds to ketamine treatment.
A new study reveals we are more susceptible to infections at certain times of the day as our circadian rhythm affects the ability of the virus to spread and replicate.
A new study reports drinking caffeine during the evening delays the internal body clock by 40 minutes.
