State-of-the art brain-imaging technology distinguishes between normal age-related memory loss and Alzheimer's disease, new research suggests. Brain scans taken while a study's participants performed object-based memory tests suggest Alzheimer's sufferers have a loss of signalling in the region of the brain known as the anterolateral entorhinal cortex.
Such signalling losses do not occur in people suffering normal age-related memory decline, such as forgetting where they left their keys or someone's name, a study found today.
Previous research suggests the anterolateral entorhinal cortex mediates communication between the region of the brain where information is first encoded and where it is stored long term.
Past studies also imply this cortex is one of the first regions in the brain to develop protein plaque tangles, which are associated with dementia's onset.
Alzheimer's disease affects around 5.5 million people in the US and 850,000 in the UK. Most sufferers live just eight-to-10 years after their diagnosis. <!-- Global site tag (gtag.js) - Google Analytics -->
