The Physician and the Peripheral Brain
There’s been a lot written in the media lately about the risks and benefits of deskilling. Smarter and smarter artificial intelligence (AI) systems are taking over countless tasks across every…
Environmental Factor – June 2024: Scientific Journeys: Mapping the brain circuitry involved in Parkinson’s disease
Observing brain cell activity in real time using sophisticated imaging methods has captivated the attention of Guohong Cui, M.D., Ph.D., since he joined NIEHS in 2014. Today, the recently tenured…
Brain Aging Advances More Quickly for People With Metabolic Syndrome
Middle-aged and older adults with metabolic syndrome had older-appearing brains, a large imaging study from the U.K. Biobank cohort suggested. Participants with metabolic syndrome had a significantly higher brain age…
Lifestyle Changes May Slow Brain Aging in Adults Younger Than 70
A structured multidomain lifestyle intervention may help slow changes in brain white matter associated with aging, a secondary analysis of data from the randomized POINTER trial suggested. Compared with a…
Environmental Factor – August 2024: Data-driven approaches fuel research on children’s brain health
Environmental exposures can elicit distinctive responses in the brain that, in turn, influence health and disease over a person’s lifetime. These exposures and their effects — known collectively as the…
New Evidence Links Progestogen Contraceptives to Brain Tumor Risk
Women using progestogen contraceptives had a significantly increased risk of meningioma, the most common type of benign brain tumor. Consistent with other recent studies, injectable medroxyprogesterone was associated with the…
‘Super Movers’ Show Signs of Exceptional Brain Aging
Adults ages 80 and older with unusually fast gait had about half the cognitive impairment risk as others, data from several studies suggested. Earlier research showed that super movers —…
Brain Disorders and TBI May Fuel Each Other
Traumatic brain injury (TBI) and neurologic disorders were linked bidirectionally in a study of older veterans. Before TBI, older adults often had epilepsy, stroke, dementia, or Parkinson’s disease diagnoses. After…
Brain Risks Tied to High Ultraprocessed Food Intake
Older adults who ate the most ultraprocessed foods had a high risk of cognitive impairment, a large longitudinal study showed. A high intake of minimally processed foods was associated with…
Brain Changes Linked With Speech-in-Noise Impairment
Difficulty understanding speech in noise was associated with faster thinning in speech-processing brain networks. These associations persisted after adjusting for hearing thresholds and hearing aid use. Speech-in-noise deficits may signal…
