A new study suggests that your home address may determine your chances of being diagnosed with dementia.
Researchers at the University of Michigan Medical School analyzed Medicare claims for approximately 5 million seniors in community health markets across the country, focusing on areas with high rates of diagnosis. Alzheimer's disease Other dementias.
The researchers found that in areas with higher diagnostic rates (called “diagnostic intensity”), residents were twice as likely to realize they had the disease, especially among people aged 66 to 74 and black and Hispanic groups.

“The number of people who receive a formal diagnosis varies by region,” said lead study author Dr. Julie Bynum, a researcher and professor of internal medicine at the university. University of Michigan Medical Schoolhe told Fox News Digital.
“These differences relate to the number of people who actually have dementia and depend on risk factors such as age, race and risk of cardiovascular disease, but these population characteristics do not explain all the differences in the proportion of people diagnosed.”

Bynum said certain factors in the health care system could play a role, such as: health care The presence of clinicians with experience in diagnosing and caring for people with dementia.
Healthcare markets with the highest rates of dementia diagnosis include Texas (McAllen, Wichita Falls, Harlingen), Miami, Florida; Lake Charles, Louisiana; Alabama (Tuscaloosa, Montgomery), Michigan (Detroit, Dearborn, Royal Oak), Oxford, Mississippi, and New York (Bronx, Manhattan).

Bynum said he wasn't at all surprised by the findings.
She said she expected to find differences in rates of formal diagnosis based on how clinics and individual doctors typically respond to patients with cognitive concerns.

“What was unexpected was that the locations of areas with high and low diagnostic density did not follow the pattern of locations with high population disease burden,” she said.
“I would have expected that in areas where dementia is a bigger problem, there would be more efforts to get these people into care homes.”

Dr. Licia Newman, Senior Director Health Services Research Alzheimer's Association researchers, who were not involved in the study, said it highlights regional disparities in the diagnosis of Alzheimer's disease and other dementias.
“This suggests that unless health systems, payers and governments make intentional efforts to promote equitable access to diagnostics, these disparities will continue to grow,” she told Fox News Digital.
Overcoming diagnostic barriers
Based on the study's findings, Bynum said people who are worried about a family member's cognitive decline may need to make a “special effort” to communicate their concerns to their doctor.
“One of the problems is that concerns can get lost in the middle of everything else. senior citizen “Patients and their doctors have to deal with this, but it's hard for doctors to sort through complaints about cognitive function,” she told Fox News Digital.

“Furthermore, we should all encourage our local health systems to develop the capacity to meet the needs of our burgeoning population through clinical and support programs.”
Newman said younger people and people from “historically underrepresented ethnic and racial groups” are at higher risk of being underdiagnosed.
“We know that there are barriers to early and accurate diagnosis of dementia at all levels,” she said.

“They go from stigma and lack of awareness of the signs and symptoms to barriers to accessing related healthcare. Health Insurance Coveragedistance to clinical sites, and lack of transportation or chaperones.”
Newman said he hopes studies like this one will inspire efforts to raise awareness of early warning signs and encourage individuals to discuss their concerns with their health care providers.
“Barriers to early and accurate diagnosis of dementia exist at every level.”
Educational programs and interventions can also increase the likelihood of receiving a timely dementia diagnosis, she added.
“After all, an accurate diagnosis is the first step to appropriate treatment and care.”
Potential limitations
Bynum noted that one of the limitations of the study is that the researchers could not determine whether the diagnosis rate was “too high or too low” based on their data alone.
“We can only say whether it's higher or lower than the national average,” she said.

“We need to know the actual number of people living with dementia in each community, but measuring that would be hugely expensive.”
But Bynum said the approach could help researchers understand how difficult it is to get a formal diagnosis in different areas.

“Studies based on claims data always have limitations,” Newman noted.
“Claims data only relates to individuals who received treatment, or in this case a diagnosis, so it excludes people who may be living with the disease but were unable to access medical care. Healthcare system Or they haven't been properly diagnosed.”

Moreover, the information collected through medical claims is collected for payment and reimbursement purposes, not for research, so it is not possible to understand factors that may be causing disparities, she added.
