As two people with considerably different symptoms may receive the same depression diagnosis, researchers wanted to determine whether this individuality also manifests in brain activity. According to the World Health…
AI estimates retinal age, revealing sex-specific ageing patterns and links to disease risk
A team from the Department of Computational Biology at the University of Lausanne has developed an artificial intelligence model capable of estimating a person’s retinal age from a simple photograph…
Deep learning refines how bionic eyes communicate with the brain
Researchers from three institutions, including UC Santa Barbara, have demonstrated that artificial intelligence has the potential to make future visual prostheses, like a bionic eye, more precise, predictable and responsive…
New Alzheimer’ s blood test may tell when symptoms are around the corner
A novel biomarker beats the leading diagnostic blood test at predicting disease progression. Small loops of genetic material may be strong indicators of imminent Alzheimer’s disease (AD) symptoms. In a…
SCOPERTA UNA NUOVA MALATTIA GENETICA DEL NEUROSVILUPPO

The brain’s language network is more extensive than previously thought
For decades, neuroscientists have known that specific regions in the brain’s left hemisphere are responsible for processing language. However, a new study by MIT researchers shows that language processing also…
Anti-amyloid Alzheimer’s drugs show no clinically meaningful effect
People with Alzheimer’s disease have high levels of a protein known as amyloid beta in their brains, detectable before symptoms begin, but its role in disease progression is uncertain. Drugs…
How you walk could help doctors tell two similar brain diseases apart
Doctors often struggle to distinguish early dementia with Lewy bodies from early Parkinson’s disease. The two neurological conditions share many symptoms, including changes in movement, and are frequently misdiagnosed in…
