People with the highest levels of cognitive enrichment had a much lower risk of Alzheimer’s and experienced symptoms years later than those with the lowest levels.

Researchers found that inflammation in the brain disrupts the energy supply of vital movement-controlling neurons. As their mitochondria fail, these cells weaken and eventually die, worsening motor problems over time. Protecting brain energy systems could open the door to slowing these symptoms.

These blockages, easily seen on standard MRI scans, are tied to toxic protein buildup linked to memory loss and cognitive decline. In some cases, they may signal Alzheimer’s earlier than other commonly used brain markers. This could help physicians detect the disease earlier, before irreversible damage sets in.

The group showed higher inflammation, signs of liver strain and elevated neurofilament light chain, a marker of neuron injury. Low choline levels appeared closely tied to these changes. The results hint that early metabolic disruptions may quietly influence the brain long before symptoms emerge.

Their decade-long research shows that lithium depletion—caused by amyloid plaques binding to it—triggers early brain changes that lead to memory loss. By testing new lithium compounds that evade plaque capture, they reversed Alzheimer’s-like damage and restored memory in mice at doses far lower than those used in psychiatric treatments.

Scientists in China have developed a promising early screening method that detects Parkinson s from subtle changes in the scent of ear wax yes, really. By analyzing specific volatile compounds in ear wax and feeding that data into an AI-powered olfactory system, they achieved 94% accuracy in identifying who had the disease. If expanded successfully, this low-cost, non-invasive technique could transform early detection and treatment of this debilitating neurological disorder.

Scientists have unveiled a powerful new imaging method, FREQ-NESS, that traces how different sound frequencies ripple through brain regions like shifting waves. This discovery could revolutionize how we understand perception, attention, and even consciousness.

These implants may one day benefit people who can't receive a cochlear implant, such as those with Neurofibromatosis type 2 (NF2) and other severe inner ear abnormalities. In a new preclinical study, researchers report on benefits in large animal models, and based on the results, hope for future trials in humans.

Until now, there has been no objective way to measure tinnitus severity and clinicians rely on patient survey questionnaires. The researchers plan to use these biomarkers to develop and test new therapies that can reduce or eliminate the phantom sounds (i.e. ringing in the ears) caused by tinnitus.

They discovered a novel line of communication between metastatic medulloblastoma and leptomeningeal fibroblasts that mediates recruitment and reprogramming of the latter to support tumor growth. The findings suggest that disrupting this communication offers a potential opportunity to treat this devastating disease.

Researchers focused on a group of interacting genes called the Hippo pathway, which serve as a 'stop growing' signal that the lab has shown to inhibit cell proliferation in the ear during embryonic development. The scientists demonstrated that the Hippo pathway also suppresses the regeneration of damaged sensory receptors in the ear and eye of adult mice.

Researchers have identified a deficit in contrast perception in people with schizophrenia. According to a review of more than 600 studies, these patients have an impaired ability to see differences in light intensity between adjacent areas, which allows us to identify shapes, textures and details in the environment.

The tumor location often prevents necessary surgical intervention. Alternative pharmacological therapy requires an in-depth understanding of the tumor molecular characteristics. To address this gap, researchers analyzed gene expression within individual tumor cells. This study reports the molecular features and interactions of tumor and immune cells associated with two craniopharyngioma subtypes that will help identify future targeted therapeutics.

The findings could guide future efforts to stimulate the regeneration of sensory hearing cells in patients with hearing loss and balance disorders. The study focuses on two cell types in the inner ear: the sensory cells that detect sound, and the supporting cells that create an environment where sensory cells can thrive. In highly regenerative species such as fish and lizards, supporting cells can also transform into replacement sensory cells after injury -- a capacity absent in humans, mice and all other mammals.

This process, which is called perceptual learning, may be enhanced by activating a major nerve that connects the brain to nearly every organ in the body, a new study in mice shows.

Results were similar for Black and white participants. These results do not prove that the MIND diet prevents cognitive impairment, they only show an association.

The cells are hybrids, part neuron and part glia, and are present in both glioma, a type of brain tumor, and in normal brain. The newly discovered hybrid cells support the groundbreaking idea that neurons are not the only cells that can generate electric signals in the brain. In glioma, the higher the firing activity of the hybrid cells, the better the patient's outcome, suggesting a prognostic value.

A new study has examined if thinking and memory skills were associated with cadmium exposure. They found no association when they looked at the group as a whole. However, when looking at Black and white people separately, it found cadmium may be tied to problems with thinking and memory skills in white people. The study found no such association in Black people. The study does not prove that cadmium causes memory problems in white people; it only shows an association.
