A Hypothalamic Circuit For The Circadian Control Of Aggression

Patients with Alzheimer's disease and other forms of dementia commonly experience the sundown syndrome, a sudden worsening of confusion, agitation, and aggression at the end of the day. Its daily pattern suggested that "sundowning," as the phenomenon is also known, may be governed by the body's internal biological clock. The study was published today in Nature Neuroscience.

Synchronized by light and darkness, the circadian clock exerts control over wake/sleep cycles, body temperature, digestion, hormonal cycles and other physiological and behavior patterns. But whether the circadian clock regulated aggressive behavior was unknown.

Mucus Protects Flu virus, New Findings

Mucus and other airway secretions that are expelled when a person with the flu coughs or exhales appear to protect the virus when it becomes airborne, regardless of humidity levels, a creative experiment discovered. The results refute long-standing studies that indicated the influenza virus degrades and is inactivated sooner as the humidity increases.

Severely Ill Psychiatric Patients Admitted Themselves To Hospital

Researchers have assessed that Severely ill psychiatric patients in Denmark have been able to decide when to admit themselves to the hospital without having to first go to the emergency department for evaluation. Previous pilot studies have suggested that patient-controlled admissions, as they are called, reduced coercion whereby patients are forcibly treated or committed. The study was published in the scientific journal Acta Psychiatry.
