| Do some diabetes drugs reduce the risk of Alzheimer’s? Posted: 11 Aug 2021 02:52 PM PDT People taking certain drugs to lower blood sugar for type 2 diabetes had less amyloid in the brain, a biomarker of Alzheimer's disease, when compared to both people with type 2 diabetes not taking the drugs and people without diabetes. The new study also found people taking these drugs, called dipeptidyl peptidase-4 inhibitors, showed slower cognitive decline than people in the other two groups. |
| People with stroke who walk 30 minutes per day may have 54% lower risk of early death Posted: 11 Aug 2021 02:51 PM PDT A new study shows that people who walk or garden at least three to four hours per week, or bike at least two to three hours per week, or the equivalent after having a stroke may have a 54% lower risk of early death from any cause. The study found the most benefit for younger stroke survivors. When people under the age of 75 exercised at least that amount, their risk of early death was reduced by 80%. |
| Posted: 11 Aug 2021 01:29 PM PDT In an effort to better characterize -- and quantify -- sensorimotor abilities and their impact on the development of people with ASD, scientists have published research that compared the fine motor control and eye movements of more than 200 people from age 5 to 29. The study showed key differences in the ways that individuals with ASD processed or reacted to stimuli compared to those who were more neurotypical, with implications for future research across age range, intelligence and setting. |

| New findings on how ketamine prevents depression Posted: 11 Aug 2021 06:16 AM PDT The discovery that the anaesthetic ketamine can help people with severe depression has raised hopes of finding new treatment options for the disease. Researchers have now identified novel mechanistic insights how the drug exerts its antidepressant effect. |
| Examining correlation between occupational noise, heart disease Posted: 10 Aug 2021 08:09 AM PDT Hearing conservation programs and policies aim to protect workers from noise-induced hearing loss, but it remains unclear whether stress reactions caused by noise exposure might also lead to other negative health outcomes. Researchers now describe how data from the Canadian Health Measures Survey do not support an association between loud noise exposure and changes in biomarkers for cardiovascular disease or outcomes. |
