Dr. Thomas Wisniewski, Director of NYU Langone's Alzheimer's Disease Research Center, shares insights from a recent study that projects new dementia cases in the US will double by 2060. New diagnostic tools have made it easier to identify early signs of Alzheimer's, and disease-modifying therapies are being approved, which can be effective if patients are treated in the earliest stages of the disease. AI is seen as a tool to help identify at-risk patients and routinely screen patients to manage the growing need for access to dementia care.
Thomas explains, "This was a study that was led by the NY Optimal Institute, which is directed by Dr. Joe Resh, who's really a leader in this area and many public health issues. He did a very thorough analysis along with his team that the annual number of incident dementia cases in the United States is projected to increase from current estimates of 500,000 to around 1 million in 2060. So basically doubling in white adults. Furthermore, in African Americans, this incidence of dementia rate is expected to triple, with the largest absolute increases in dementia cases going to be in the oldest old population."
"There was perhaps a lack of awareness of the prevalence of dementia in past decades. But now the importance of making an accurate diagnosis and recognition of dementia is becoming much more prominent in the medical literature and in the medical profession. And that message, I think, is permeating to the lay public as well. So there hasn't been a change in the definition so much, but there is an increase in knowledge in the medical profession about the importance of making this diagnosis, and people living alone."
"It's really been a dramatic change. So, apart from being a cognitive neurologist, I'm also a board-certified neuropathologist, and it used to be that making the definitive diagnosis of Alzheimer's disease required a chunk of brain. I'm delighted I don't need those chunks of brain anymore to make a diagnosis of Alzheimer's disease. There are now very clear clinical criteria and biomarker definitions for making a very accurate diagnosis of Alzheimer's disease."
