The exact number of PSP cases in Canada is not known, as PSP is considered a rare disease and there is no central database for tracking cases. However, estimates suggest that PSP affects approximately 3 to 6 people per 100,000 individuals in the general population. This means that in Canada, there may be between 1,000 to 2,000 individuals with PSP.
It's important to note that PSP can be difficult to diagnose, and many cases may be misdiagnosed or underreported. Additionally, PSP shares many symptoms with other neurological conditions, such as Parkinson's disease and Alzheimer's disease, which can make diagnosis challenging. As research into PSP continues, it's possible that the estimated number of cases in Canada may change over time.
