Parkinson's disease

What it is

Parkinson's disease is a progressive loss of dopamine-producing neurons that causes tremor, stiffness, slowness and, later, cognitive and autonomic problems; it is the fastest-growing neurological condition worldwide. Levodopa still relieves symptoms better than anything newer, and no treatment yet slows the disease. The research front is early detection (skin and spinal-fluid tests for misfolded alpha-synuclein), the gut and brain-drainage theories of how it starts, GLP-1 drugs, and large platform trials testing several candidate drugs at once.
