Link Between Hearing And Cognition Starts Earlier Than Believed

Even the earliest stage of hearing loss — when hearing is still considered normal — is linked to cognitive decline, according to a study[1] from researchers at Columbia University Vagelos College of Physicians and Surgeons. Age-related hearing loss is one of the most common health disorders of aging, affecting two-thirds of those over age 70. […]

Targeting Alpha-synuclein In The Gut May Slow Parkinson’s Disease

Aggregates of the protein alpha-synuclein arising in the gut may play a key role in the development of Parkinson’s disease (PD). Investigators are testing the hypothesis that by targeting the enteric nervous system with a compound that can inhibit the intracellular aggregation of alpha-synuclein, they can restore enteric functioning in the short term, and possibly […]

Neuron Transplant May Avert Epilepsy Following Brain Injury

A new cell therapy enhanced memory and prevented seizures in mice after traumatic brain injury, researchers from the University of California, Irvine report[1]. The researchers transplanted embryonic progenitor cells capable of generating inhibitory interneurons, a specific type of nerve cell that controls the activity of brain circuits, into the brains of mice with traumatic brain […]

Lithium Can Reverse Radiation Damage After Brain Tumor Treatment

Children who have received radiotherapy for a brain tumor can develop cognitive problems later in life. In their studies on mice[1], researchers at Karolinska Institutet have now shown that the drug lithium can help to reverse the damage caused long after it has occurred. Nowadays, four out of five children with a brain tumor survive. […]

White Noise Backgrounds Improve Distinction Between Tones

Against a background of continuous white noise, hearing pure sounds becomes even more precise, researchers from the University of Basel show in a new study. The findings could be applicable to the development of more sensitive cochlear implants. Despite the importance of hearing in human communication, we still understand very little of how acoustic signals […]
