Alzheimer’s Disease 2020 Facts and Statistics
There
are over 400 types of dementia. While that number is staggering, the most
common cause of dementia
is due to Alzheimer’s disease, according to the 2020 Facts and Figures report
published by the Alzheimer’s Association (alz.org). Other better-known types of
dementia include vascular, Lewy Body disease, frontotemporal dementia, and
early-onset dementia.
As of the year 2020, Alzheimer’s disease (AD) accounts for
between 60 to 80 percent of dementia cases. Just like coronary artery disease
is heart disease, Alzheimer’s is a brain disease and is a degenerative
condition. People who suffer from AD will often begin 20 years or more before a
person notices symptoms. In most cases, memory loss and language problems are
the first indicators there might be a problem. Difficulty remembering recent
conversations, meals, names, or events, as well as apathy and depression,
become prevalent in the early stages of the disease, which are often not yet
medically diagnosed.
Risk factors for Alzheimer’s include age, genetics, family
history, and lifestyle. Age is the most significant risk factor for what is
known as late-onset Alzheimer’s, and the vast majority of people who develop AD
are 65 and older. The percentage of people living with Alzheimer’s increases
dramatically with age. Those people who are 65-74 account for 3 percent of the
cases, people age 75-84 account for 17 percent, and those who are 85 and older
account for 32 percent of Alzheimer’s patients. Though the disease is becoming
commonplace, it is not a normal part of aging.
Your gene pool also may increase your risk of contracting
Alzheimer’s disease. The identified genes are all variants of the
apolipoprotein E gene (APOE) and are designated APOE-e2, APOE-e3, and the one with the most
substantial impact on the risk of late-onset Alzheimer’s, APOE-e4. Everyone
inherits one of the three forms, called alleles, of the APOE gene, and
depending on the combination, your risk of AD may increase. There seem to be
marked differences in gene predominance among racial and ethnic groups, but
more research is needed to get consistent results from testing.
Sadly, if you have no family history of Alzheimer's disease,
it does not preclude you from developing the disease; however, if you do have a
first-degree relative, like a parent or sibling, with Alzheimer's, you are in a
higher risk category. If there are more than one first-degree relatives with
the disease, your risk grows again. When diseases run in the family system,
more than just genetics is in play. Non-hereditary shared factors like levels
of physical activity, access to healthy foods, sleep patterns, and lifestyle
habits, including smoking, may play a role.
There is sufficient evidence from population-based
perspectives that our modifiable risk factors, such as regular physical
activity, diabetes management, decreasing obesity and smoking, and managing hypertension,
are associated with a reduction in cognitive decline. Practicing lifelong
learning and cognitive training are also associated with reduced risk of
degenerating cognition. While maintaining a healthy lifestyle cannot prevent
you from developing Alzheimer’s disease, it can reduce your risk.
There is an estimated 5.8 million Americans age 65 or older
living with Alzheimer's disease, and projections are that in 2050 more than 14
million Americans will be living with the disease. Many more cases likely
exist, as Alzheimer's dementia is often underdiagnosed or unreported. On
average, a primary care physician will report patient cognitive impairment 92
percent of the time, with 64 percent of physicians saying they always inform
their patients. That leaves 36 percent of doctors who do not always tell their
patients, of which 73 percent say it is premature to relay the data before a
full diagnostic workup, and 41 percent saying brief cognitive assessments have
high rates of false positives and negatives.
As Alzheimer’s disease prevalence challenges the medical
community to find a cure, living with Alzheimer’s at some level has become the
expected norm. Across the US, states report varying incidences of Alzheimer’s.
There are massive impacts to state budgets as it pertains to federal Medicare
and Medicaid funding, county and community support levels, unpaid caregivers in
family systems, and so much more. Alzheimer’s disease has far-reaching effects
today and in the future for ourselves and our loved ones. Until the facts and
statistics show a reversal in favor of cognitive health, it is best to prepare
for an Alzheimer’s eventuality somewhere in your family system.
We help families prepare for the possibility of a serious
illness, like Alzheimer’s. If you would like to discuss your particular needs
and concerns with us, please contact us to schedule a meeting. We look forward
to hearing from you.
