Dormant viruses lying hidden in the nervous system can give rise to Parkinson’s disease, according to a newly-published biological model. The article describing this finding, “How microcompetition with latent viruses can cause α synuclein aggregation, mitochondrial dysfunction, and eventually Parkinson’s disease,” was published in the Journal of NeuroVirology. Malfunctioning mitochondria — structures within cells that provide energy —  and misfolded clumps of the alpha-synuclein protein are two hallmarks of Parkinson’s; but precisely what causes them remains…
