A research team has discovered that Dlgap2, a gene that helps facilitate communication between neurons in the nervous system, is associated with the degree of memory loss in mice and risk for Alzheimer’s dementia in humans. When studying post-mortem human brain tissue, the researchers also discovered low levels of Dlgap2 in people experiencing ‘poorer cognitive health’ and ‘faster cognitive decline’ prior to death.
Hyperbaric oxygen treatment: Clinical trial reverses two biological processes associated with aging in human cells
A new study indicates that hyperbaric oxygen treatments (HBOT) in healthy aging adults can stop the aging of blood cells and reverse the aging process. In the biological sense, the adults’ blood cells actually grow younger as the treatments progress.
In a study of women aged 80 years and older, living in locations with higher exposures to air pollution was associated with increased depressive symptoms.
A study has identified certain regions in the retina – the lining found in the back of the eye – that are more affected by Alzheimer’s disease than other areas. The findings may help physicians predict changes in the brain as well as cognitive deterioration, even for patients experiencing the earliest signs of mild impairment.
Both of Andrew Kiselica’s grandfathers developed dementia when he was in graduate school.
Seeking to develop effective interventions, researchers examined the psychological and environmental factors that lead to patterns of loneliness in different age groups.
Social distancing introduced in response to COVID-19 is increasing feelings of loneliness in Scotland’s older population and impacting their wellbeing, according to a new study.
