May 31st 2024, 12:25

Scientists have studied the main source of serotonin in the brain -- the dorsal raphe nucleus (DRN). By studying how activating the brain's 'serotonin center' affects awake animals for the first time, they found that serotonin from the DRN activates brain areas that affect behavior and motivation. Results show that DRN serotonin stimulation causes activation of the cerebral cortex and the basal ganglia, brain areas involved in many cognitive functions.

May 31st 2024, 12:20

Some 13% of older adults are diagnosed with traumatic brain injury (TBI), according to a new study. These injuries are typically caused by falls from ground level. Researchers followed about 9,200 Medicare enrollees, whose average age was 75 at the start of the study, and found that contrary to other studies of younger people, being female, white, healthier and wealthier was associated with higher risk of TBI.

May 30th 2024, 13:16

A new study is one of the first explorations of prescribing patterns of tricyclic antidepressants for treatment of diabetic peripheral neuropathy at healthcare facilities predominantly serving diverse populations of low socioeconomic status. The current body of evidence, much of it established and confirmed in studies by scientists, supports the existence of a relationship between long-term use of anticholinergic medications, such as tricyclic antidepressants, and cognitive impairment, including dementia. Research suggests use of anticholinergics in older adult populations increases risk of dementia 30 to 50 percent.
