Why hearing aids might slow cognitive decline in older adults

Results from a clinical trial indicated that hearing aids may play a part in reducing long-term cognitive decline for older adults.

According to the University of South Florida, it was the largest randomized, controlled clinical trial testing the efficacy of hearing aids for reducing long-term cognitive decline in older adults. ACHIEVE evaluated patients between ages 70 and 84 with untreated hearing loss. These patients were free from substantial cognitive impairment.

Researchers conducted the study across four U.S. study sites, evaluating 977 total participants across two populations. Healthy community volunteers included 739 participants, while 238 participated in the Atherosclerosis Risk in Communities (ARIC) study.

The multisite study found that, in older adults at increased risk for cognitive decline, hearing intervention slowed down the loss of thinking and memory abi…

This device could help prevent strokes during surgery

Researchers at the University of South Florida have developed a device that could help prevent strokes in patients during surgery.

The researchers call their device a DCS, for diffuse correlation spectroscopy. This optical monitoring tool uses fiberoptics to emit light and capture a returning signal. It monitors blood flow to the brain and offers real-time information during surgery.

Doctors receive alerts when abnormalities occur in the way the light travels, potentially indicating stroke or brain bleed. The USF non-invasive device uses small plastic caps attached to the head.
