Parkinson's disease death

Parkinson’s disease itself is not fatal and won’t cause death. As a matter of fact, some PD patients can live a normal or near-normal life. Plus there hasn’t been a universal consensus on whether or not Parkinson’s disease causes higher mortality compared to the general population, however, it is believed that Parkinson’s disease complications could lead to fatal events.

Causes of Parkinson’s disease death. A study conducted in Austria has summarized the reasons for Parkinson’s disease death. Among all, Ischaemic heart and cardiovascular disease are the number one causes followed by Parkinson’s disease itself. Here are the details by percentage:

• Ischaemic heart and cardiovascular disease (30%)

• Parkinson’s disease(23%)

• Cerebrovascular disease (14%)

• Neoplasma(12%)

• Gastrointestinal and genitourinary disease(6%)

• Pneumonia and COPD(10%)

• Accident, injury, poisoning (4%)

  Another study conducted in Korea shows similar findings with nervous system disease, circulatory disease, respiratory disease, neoplasm as four major causes of Parkinson’s disease death. The data from both studies also demonstrated that Parkinson’s disease can increase mortality.

Prognostic factors of Parkinson’s disease In addition, a recent Meta review also identified prognostic factors that are independently associated with Parkinson’s disease as follows:

• Increasing age (either at onset or recruitment)

• Presence of dementia

• Male sex

• Higher Hoehn & Yahr stage

• PIGD phenotype, prominent Bradykinesia or lack of tremor

• Higher Parkinsonian impairment score

• Presence of psychosis or hallucinations

• Presence of extensor plantar response.

In summary With more studies coming up from a variety of populations, regions, and ethnicities, it is believed now that Parkinson’s disease increases despite high heterogeneity. The increase varies depending on several factors including experiment design, case inclusion standard, and also treatments
