Researchers have developed a blood test that detects Parkinson’s disease, potentially establishing a way to help diagnose the condition before nervous system damage worsens.

DURHAM – People who have a gene variant associated with an increased risk of developing Alzheimer’s disease also tend to have changes in the fluid around their brain and spinal cord that are detectable years before symptoms arise, according to new research from Duke Health.
The work found that in people who carry the APOE4 gene variant, which is found in roughly 25 percent of the population, the cerebrospinal fluid contains lower levels of certain inflammatory molecules. This raises the possibility that these inflammatory molecules may be collecting in the brain where they may be damaging synapses, rather than floating freely in the cerebrospinal fluid.
