Scientists have identified five subtypes of Alzheimer's disease, and they say the discovery represents the "first step" toward developing personalized treatments for the widespread condition.
In a new study, scientists were able to sort more than 400 patients with Alzheimer's into five groups based on the levels of specific proteins in their cerebrospinal fluid (CSF), the clear liquid that surrounds the brain and spinal cord. These proteins are linked to biological processes that get derailed in Alzheimer's, such as the formation of new proteins and brain inflammation.
