Neurodegenerative Disease
Neurodegenerative disease is a broad class of progressive neurological disorders characterized by the selective, irreversible loss of neurons in the brain or spinal cord, leading to deteriorating cognitive, motor, or autonomic function.
Overview
Prominent examples include Alzheimer's disease, Parkinson's disease, ALS, and Huntington's disease. At the chemical level, neurodegeneration is fundamentally a protein chemistry problem: misfolded proteins such as amyloid-beta and alpha-synuclein form toxic aggregates that propagate through the brain in prion-like patterns, making these molecular mechanisms the primary targets of drug discovery.
Why it matters
These conditions represent a major and growing public health crisis as global populations age, with Alzheimer's alone projected to affect tens of millions by mid-century. Neuroimaging technologies — MRI, PET, and diffusion tensor imaging — are critical diagnostic tools that connect disease research to the physics of magnetic resonance and advanced engineering of imaging systems.
