I have not been diagnosed with PD. I have RBD and a sore shoulder and leg and a poor sense of smell, and my last blood test showed a low WBC so I went to Doctor Google and: Low White Blood Cell Counts May Indicate Early Stages of Parkinson’s parkinsonsnewstoday.com/202...
“In conclusion we report that lower lymphocyte count is associated with higher risk of subsequent diagnosis of PD in a large UK cohort,” the researchers wrote.
Evidence also suggested the relationship between low white blood cell counts and Parkinson’s may be causal, meaning one (low counts) leads to the other (the disease). More studies, however, will be needed to clarify this, the researchers wrote.
“PD is known to have a long latency between biological onset and clinical presentation. As such a proportion of the incident PD cases included may have been clinically incident but biologically prevalent at the time of [patient] recruitment,” the researchers wrote. “We cannot be certain that lymphopenia precedes biological disease onset and it could therefore be a marker of pre-clinical PD.”
Still, “there is evidence to support a mechanistic link between lower lymphocyte count and PD,” they continued. “Further work is required to replicate these findings in other cohorts, and to address the mechanisms underpinning this relationship.”
