The Fight Continues Against Alzheimer’s Disease

Arandia

In 1983, U.S. President Ronald Reagan declared November as National Alzheimer’s Disease Awareness Month to foster awareness and inspire action against Alzheimer’s disease, the most common cause of dementia among older adults. Dementia is the loss of cognitive functioning, which affects memory, behavior, problem solving, self-management and in some cases loss of emotional control and personality changes, all of which interfere with daily activities and severely affect quality of life.

Today, the fight continues.  According to the Alzheimer’s Association 2019 Alzheimer’s Disease Facts and Figures report, an estimated 5.8 million Americans are living with Alzheimer’s disease; and by 2050, this number is projected to rise to nearly 14 million Americans. Alzheimer’s disease is the sixth leading cause of death in the U.S., and the fifth leading cause of death among individuals aged 65 and older.

The causes of Alzheimer’s disease are complex and a cure remains elusive. The disease is primarily caused by the toxic accumulation of proteins (beta amyloid and tau), which interrupt connections and signaling between neurons, eventually leading to nerve cell death. As the disease progresses, damage spreads throughout the brain, impairing its functions. Over time, the brain begins to shrink.

Memory problems are typically the earliest signs of cognitive decline. According to the National Institute on Aging, someone with Alzheimer’s disease may also experience one or more of the following signs:

  • Memory loss that disrupts daily life, such as getting lost in a familiar place
  • Difficulty completing familiar tasks at home, at work or at leisure
  • Decreased or poor judgment
  • Misplacing things and being unable to retrace steps to find them
  • Changes in mood, personality or behavior

Having any of these signs does not mean you have Alzheimer’s disease. Speaking to a health care provider is always best. To learn more about the signs and symptoms of Alzheimer’s disease, visit the National Institute on Aging website.

Studies have shown that older age, genetics, family history, sex and gender (women are at increased risk) and race and ethnicity (African Americans and Hispanics/Latinos are at increased risk) are all non-modifiable risk factors for Alzheimer’s disease. Comorbidities, as well as environmental and lifestyle factors also play an important role. The presence of cardiovascular and metabolic conditions, including heart disease, diabetes, obesity, high blood pressure and high cholesterol, heighten the risk for Alzheimer’s disease. A healthy lifestyle, based on a heart healthy diet emphasizing fruits and vegetables, regular physical activity and social engagement can help mitigate these risk factors for cognitive decline and dementia.  

National Alzheimer’s Awareness Month is a time to also recognize and support caregivers — family members and friends who are caring for a loved one with Alzheimer’s disease.  Caregiving can be both rewarding and challenging. Among the more than 16 million caregivers in the U.S. providing unpaid care for a loved one, two-thirds of caregivers are women, while one in three caregivers are 65 years old and older. Last year, the Texas Health and Human Services released “A Profile of Informal Caregiving in Texas,” noting that caregivers report experiencing elevated stress and adverse effects on personal health and employment. Caregivers are urged to seek out support groups and respite care to help them along their journeys.

Locally, the Texas Tech University Health Sciences Center Garrison Institute on Aging is a collaborative initiative whose mission is to advance healthy aging and aging-related health issues through innovative research, education and community outreach.

Texas Tech Physicians

Texas Tech Physicians is a physician group and part of the School of Medicine and the Paul L. Foster School of Medicine.

Clinics are located in Amarillo, El Paso, Lubbock and the Permian Basin, encompassing 108 counties of Texas and New Mexico comprising 103,000 square miles with a population of 2.6 million people. Receiving care in a medical school setting is unique – many Texas Tech Physicians are also teachers. They must remain up-to-date in new treatments and diagnostics, not only to care for their patients, but also to pass on that knowledge to resident physicians, physicians studying in fellowships and medical students.
