How the eyes might be windows to the risk of Alzheimer’s disease

Adults with mild cognitive impairment (MCI), a precursor to Alzheimer's disease, have greater pupil dilation when taking cognitive tests than their cognitively normal peers. Task-evoked pupillary response may be a cost-effective, and low invasive screening test for those at genetic risk for Alzheimer's before the symptoms of the disease take hold. ... Read More...

Routine hits playing football cause damage to the brain

Sustained hits following one season of playing football are enough to cause structural alterations to the brain. When players sustain a concussion, structural brain integrity decreases, and levels of tau increase. Researchers say, while concussions are a prime concern for those who play football, sustained hits also pose a threat to neurological health.... Read More...

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.... Read More...
