How noise and age affect brain’s sound processing

Noise-induced hearing loss and hearing loss due to aging have different effects on sound processing in the brain. Researchers suggest each type of hearing loss should have its own specific treatment.

Why are we able to see moving objects against moving backgrounds?

The human brain can desensitize background motion and focus on smaller moving objects in the foreground as a result of activity in the middle temporal visual area. However, our ability to pick out smaller objects changes over time. Younger people are better at picking out foreground objects moving, while those over 65 have heightened awareness of objects moving in the background.

Smart glasses follow our eyes and focus automatically

A newly designed set of 'smart glasses' could help to correct the vision of millions of people with age-related presbyopia. The autofocals work much like the eyes and include eye tracking sensors which enable to triangulate where a person is looking and determine the precise distance of the object.

Low-carb ‘keto’ or ‘Atkins-style’ diet may modestly improve cognition in older adults

A small scale pilot study reveals adults with mild cognitive impairment may have improved brain function and memory when they switch to a high-fat, low-carb diet.

Disrupted sleep in one’s 50s, 60s raises risk of Alzheimer’s disease

Sleep disruptions during middle age may be a potential biomarker for developing Alzheimer's disease later in life. Researchers found those who experienced sleep problems in their 40s and 50s had more amyloid beta accumulation in their brains later in life. Those whose sleep problems started in their 50s and 60s had increased levels of tau. Additionally, higher levels of tau were discovered in the brains of those who lacked synchronized brain waves associated with a good night's sleep.

Commonly prescribed drugs could increase the risk of dementia

Anticholinergic drugs, commonly prescribed to treat a range of disorders, from Parkinson's disease to bladder conditions, may increase dementia risks. The increased risk was linked to anticholinergic antidepressants, antipsychotics, bladder control, epilepsy and Parkinson's disease medications. There were no increased risks associated with other types of anticholinergics, such as gastrointestinal drugs or antihistamines.

Supplements for brain health show no benefit

Supplements marketed to promote 'brain health' often overstate the products' benefits and do little-to-nothing to improve the aging brain. Researchers investigate the hidden dangers and false claims behind these products, which are highly profitable for manufacturers, but not so beneficial for consumers.
