Demographic and clinical factors associated with Parkinson's mortality rates

Demographic and clinical factors associated with Parkinson's mortality rates
3rd January 2012

Survival among patients with Parkinson's disease is associated with demographic and clinical factors, according to new research.

A study at Washington University School of Medicine has revealed that dementia is associated with a significant increase in mortality that varies among different sexes and races.

Moreover, the chances of surviving the condition vary depending on the type of disease a patient has.

Although Parkinson's disease is a common condition, there is conflicting data over survival rates.

However, Dr Allison W Willis, lead researcher on the study, and her colleagues discovered that sex and race could "significantly predict" survival.

Female patients who were Hispanic or Asian had a lower adjusted risk of death than white men, according to the study.

Black patients have the highest crude death rate at 66.4 per cent, followed by white patients at 64.6 per cent, Hispanics at 55.4 per cent and Asian patients at 50.8 per cent.

It was also identified that patients with Parkinson's disease and dementia had a greater likelihood of death than those without dementia.

Patients with terminal Parkinson disease were also found to be hospitalised frequently for cardiovascular disease and infection but rarely for Parkinson disease.

Unfortunately, treatment has yet to be developed to reduce mortality rates among Parkinson's patients.

However, levodopa therapy is believed to offer improved quality of life.
