Almost 8% of Medicare recipients in Harris County likely have Alzheimer's or another type of dementia, according to researchers developing the first-ever national dementia surveillance system. Why it matters: The lack of a widely accepted monitoring tool has made it hard to get a fix on the prevalence of dementia and to direct spending on care, even as science makes it easier to clinically diagnose symptoms and slow cognitive decline. The big picture: Cases of dementia — a general term for loss of cognitive abilities — are expected to triple worldwide by 2050 as the population ages. By the numbers: Texas has the second-highest dementia prevalence rate in Medicare recipients of any state at 8.1%, according to the Dementia DataHub. - In the Houston area, Chambers County showed the highest prevalence rate with 8.8%, followed by Harris County with 7.9%, Brazoria County with 7.6% and Galveston County with 7.5%.
- Liberty County's prevalence rate is 7.3%, Waller County is 7.2%, and Montgomery and Fort Bend counties each have a 7.1% rate.
Reality check: Dementia is notoriously difficult to diagnose, and this tool "still only involves people with diagnosed dementia," the Alzheimer's Association noted. - "Additional tools are needed to fully understand total dementia prevalence across the country, while also expanding efforts to ensure a timely diagnosis for all in need."
The other side: The surveillance tool could be helpful in directing public health efforts, but improving care still requires higher Medicare reimbursements for dementia patients, John A. Hartford Foundation president Terry Fulmer tells Axios. |
