Research on parkinson's disease diagnosis is ongoing, with studies exploring the use of mri scans and other tests to build a more complete picture of the disease. Some studies are investigating the relationship between brain imaging and disease progression, as well as the potential of new biomarkers for diagnosis. The field of research appears to be broad, with some outlets discussing parkinson's in relation to other conditions, such as als, and others focusing on specific aspects of the disease, like brain cleanup signals and toxic proteins.
