Almost everyone knows this feeling. After a night of poor sleep, it is more difficult to concentrate. Your thoughts wander, your reaction times slow down, and your mental clarity diminishes, especially when you need to be most alert. New research from MIT sheds light on what happens in the brain during these brief lapses in […]Almost everyone knows this feeling. After a night of poor sleep, it is more difficult to concentrate.

How Cancer Disrupts the Brain and Triggers Anxiety and Insomnia
Scientists have discovered that breast cancer can disrupt the brain’s internal clock almost immediately after the onset of cancer, without anyone noticing. In mice, tumors flattened the natural daily rhythm of stress hormones, disrupting the feedback loop between the brain and body that regulates stress, sleep, and immunity. Remarkably, when the researchers restored the correct […]Scientists have discovered that breast cancer can disrupt the brain's internal clock almost immediately after the onset of cancer, without anyone noticing.

A Weak Internal Clock Can be an Early Warning Sign of Dementia
Your daily rhythm may be more important to your brain health than previously thought. Older adults with weaker, more disrupted activity patterns were far more likely to develop dementia than those with stable routines. A later daily energy peak was also associated with a higher risk. The study points to the internal clock as a […]Your daily rhythm may be more important to your brain health than previously thought.

Can Sleep Deprivation Have an Antidepressant Effect?
Most people who have ever pulled an all-nighter are familiar with this feeling of “exhaustion and overexcitement.” Although the body is extremely tired, the brain feels euphoric, dazed, and almost dizzy. Neurobiologists at Northwestern University were the first to discover what causes this “punch-drunk” effect. In a study, the researchers induced mild, acute sleep deprivation […]Most people who have ever pulled an all-nighter are familiar with this feeling of “exhaustion and overexcitement.” Although the body is extremely tired, the brain feels euphoric, dazed, and almost dizzy.

Study Shows that Untreated Sleep Apnea Doubles the Risk of Parkinson’s Disease
New findings suggest that people who do not seek treatment for obstructive sleep apnea have a higher risk of developing Parkinson’s disease. The use of continuous positive airway pressure (CPAP) can reduce this risk by improving sleep quality and maintaining a constant airflow throughout the night. The study was published in JAMA Neurology and analyzed […]New findings suggest that people who do not seek treatment for obstructive sleep apnea have a higher risk of developing Parkinson's disease.
