Most neurodegenerative diseases have animal parallels such as Alzheimer’s in chimpanzees, multiple sclerosis in macaques, Lou Gehrig’s disease in dogs, but nothing like Parkinson’s has ever been seen in any species but humans. Synuclein and the Coelacanth: The Molecular and Evolutionary Origins of Parkinson's Disease delves into the causes of Parkinson’s disease and how the evolution of the human brain has left us uniquely vulnerable. Genetic risk factors, environmental toxins, and neuroanatomy are woven together in a multidisciplinary discussion that ranges from subatomic physics to socioeconomics. Connections between neurodegenerative disease, neural pathways, and innate immunity are explored. Finally, the author discusses new therapeutic agents are being developed that hope to go beyond just treating the symptoms of Parkinson’s and actually halt the disease.
