When looking at dogs with multiple examinations, a total of five dogs were followed at Stage 1 for a minimum period of 0.9 years and a maximum period of 2.3 years (mean of 1.2 years)
without any signs of progression to subsequent disease stages (Table 2).
«DATATOP subjects were recruited at early disease stages,
without apparent
signs of dementia and prior to needing dopamine - supplementing drugs, making this cohort ideal for studying PD
progression,» explains Jing Zhang, MD, PhD, Department
of Pathology at the University
of Washington School
of Medicine (Seattle).
