Disease progression over time for Parkinson's
In the very earliest stages of Parkinson’s, one of the most common symptoms is REM sleep behaviour disorder, in which the person acts out their dreams during sleep, often through movements or sounds. An impaired sense of smell and depression are other possible symptoms at this stage. A new study from Chalmers University of Technology, Sweden, and Oslo University Hospital, Norway, has identified a possible “window of time” at this stage, during which novel biomarkers are measurable in the blood. At later stages of the disease, nerve damage in the brain leads to motor symptoms - but the researchers’ findings represent a step toward detecting and counteracting the disease before it reaches that point.
