Scientists have created a blood test that can estimate when Alzheimer’s symptoms are likely to begin. By measuring a protein called p-tau217, the model predicts symptom onset within roughly three to ...

Researchers believe the test could be a new way to foresee how quickly the disease will progress, but evidence so far is preliminary. A growing body of research links insulin resistance, a hallmark of ...

Among the many difficult features of Alzheimer’s is that doctors can never really say with certainty which patients who show signs of memory loss will go on to develop the neurodegenerative disorder.

Alzheimer’s disease has long been a diagnosis that arrives only after memory begins to fray, by which time brain damage is already extensive. A new experimental drug called NU-9 is challenging that ...

During the quiet hours of sleep, your brain is hard at work. It sends out tiny electrical signals that ripple across networks deep in your mind. For years, scientists knew these patterns told stories ...

There is nothing worse than being told to "stay positive" after a rough day at the office, bad doctor's visit, or messy breakup. Yet, while it can be incredibly difficult to stay positive during ...
