There has never been a more exciting time in Alzheimer care than today. Promising innovations in therapies and diagnostics for this most common form of dementia are emerging at a faster pace than at any other time in medicine. At the same time, science is revealing that, for some, preventive behavioral measures can meaningfully delay progression. These developments together provide greater reason for optimism for those at risk of Alzheimer than at any other time in recent memory. <\/p>\n
And these medical achievements couldnt come at a better time. More than 6 million patients nationwide live with Alzheimer disease (AD). By 2050, this number could reach nearly 13 million with costs of care topping $1 trillion.1 <\/p>\n
Yet, this rapid pace of change also threatens to confuse providers and patients who may not be up to date on the latest science on Alzheimer. Dispelling long-perpetuated misunderstandings of this complicated condition may open more avenues leading to better outcomes. <\/p>\n
#1: Only older patients need to worry about AD. <\/p>\n
#2: AD is primarily an inherited genetic disease. <\/p>\n
#3: Most patients dont want to know if they are at risk of developing AD. <\/p>\n
#4: Only high-powered imaging tests can help evaluate for AD. <\/p>\n
#5: Only pharmacological therapies can meaningfully address AD. <\/p>\n
Fact: AD often begins in the brain in middle age sometimes decades before symptoms emerge. While age increases risk, it is not a direct cause of Alzheimer and patients of all ages can begin to take steps to potentially slow cognitive decline. A recent study conducted by the CDC showed pediatric patients can reduce their risk of developing AD later in life in a number of ways, from managing their blood pressure and blood sugar, to being physically active.2 <\/p>\n
Fact: Genetics are only one possible factor in the development of AD, and having a family history of Alzheimer does not necessarily doom one to developing the disease. At the same time, a lack of family history does not eliminate the possibility a person will develop Alzheimer. There are 2 categories of genes that influence whether a person develops a disease: risk genes and deterministic genes. While Alzheimer genes have been found in both categories, less than 1% of AD cases are believed to be because of deterministic genes.3 <\/p>\n
Even those who have these genes may never develop AD; risk genes increase the likelihood of developing a disease, but do not guarantee it will happen. Researchers have found several such genes that increase risk. Apolipoprotein (APOE) 4, one common form of the APOE gene, has shown to have the strongest impact on risk, as researchers estimate that between 40-65% of people diagnosed with Alzheimer have the APOE-e4 gene.3 Those who inherit copies of APOE-e4 from their parents have an increased risk of developing AD, but it is not a certainty. These individuals can still take steps to mitigate their risk by reducing environmental factors or taking preventative steps to better their condition. <\/p>\n
Fact: A recent Harris Poll commissioned by Quest Diagnostics found that only 4 in 10 Americans surveyed said they would speak to their clinician right away if experiencing memory or cognitive loss, suggesting an aversion to being diagnosed with a dementia like Alzheimer. Yet, when asked directly, the majority (7 out of 10) expressed a desire to know if they have AD as early as possible to allow for treatment illustrating a willingness to confront the prospect of a scary medical diagnosis if treatment can enhance the odds of a favorable outcome.4 <\/p>\n
Fact: New diagnostics, including those using simple blood tests, are rapidly opening doors to accessible risk evaluation for many. These blood tests generally help assess -amyloid or tau, 2 brain proteins associated with Alzheimer pathology in the brain. Amyloid- creates plaques which may lead to tangles of tau in the brain. For this reason, many diagnostic companies, including Quest Diagnostics, are focused largely on tests for amyloid protein, given its potential to detect early stages of disease.5 <\/p>\n
Growing acceptance of blood tests is needed, as emerging pharmaceutical treatments for Alzheimer will require better tools to assess patients. This is because conventional tests, such as PET scans and those that use cerebral spinal fluid, are expensive and specialist dependent. Plus, there is a growing shortage of neurologists.6 Laboratory tests, when combined with other screening methods, can be a powerful tool in crafting an effective patient care plan in fact, in a survey of physicians, 84% said testing for early risk of AD will lead to earlier and improved disease management. Among U.S. adults, 86% agree, stating they believe blood tests for the early detection of Alzheimer risk will increasingly become a regular part of preventative care.7 <\/p>\n
Fact: For some, Alzheimer may be a preventive condition. New research shows it is possible to reduce risk of AD or at least slow progression. Some studies suggest people who exercise more, including walking an increased number of steps at an advanced pace, have better memory retention and are less likely to develop conditions like Alzheimer or dementia.8 Studies have also shown creative activities like playing games, learning an instrument or reading books may help preserve brain function.9 As a patient gets older, it can be more challenging to maintain social activity, though some research shows this can also help preserve mental function and slow mental decline.10 Yet, the same lifestyle choices and behaviors that can reduce risk of developing heart disease, diabetes and other chronic conditions may also offer some protection against Alzheimer. Addressing depression and hearing loss are other key steps to reduce risk.11 <\/p>\n
Fact: Cognitive decline is often not because of dementia and can be reversed. There are other potentially reversible causes of cognitive decline that can mimic dementia. These include things as minor as medication side effects or hormonal imbalances, and can be as severe as other chronic conditions like HIV. In 1 study, as many as one in 5 (19.17%) individuals (most over the age of 60 years) with cognitive issues were found to have a reversible condition, such as adverse effects from medication or hormone imbalances.12 Without screenings, conditions that mimic dementia may go undiagnosed in a patient and cause adverse health effects. If properly diagnosed, these conditions, may be treated to potentially slow or reverse any associated cognitive decline.13 <\/p>\n
Certain tools aim to address this. As an example, uMETHOD Health, a health technology company specializing in precision medicine for chronic diseases, recently worked with Quest Diagnostics to nationally debut a risk assessment and care plan service for patients with cognitive decline. The service, called RestoreU, employs artificial intelligence to crunch data on a persons lab test results and health history, including comorbidities, lifestyle habits and medications, to help identify if risk of cognitive decline is because of a reversible cause.14 <\/p>\n
With so much attention on emerging therapies for AD, it is easy to overlook the growing body of science suggesting a preventive care approach can help delay the onset of Alzheimer and other dementias in some patients. When it comes to conditions like Alzheimer and dementia, one thing remains clear: patients and providers both seek the ability to provide an early diagnosis and craft the best care plan possible. Though so many remain affected by cognitive conditions, there are steps that can be taken, as with any other health condition, to mitigate risk and ease symptoms. By speaking with a provider about these changes, patients may find these conditions more manageable than first anticipated. <\/p>\n
