Dementia is the name given to a group of conditions characterized by impairment of at least two brain functions. Symptoms generally include forgetfulness, confusion, impaired thinking abilities, limited social skills, and more. Dementia is categorized as a common health condition, primarily affecting mature adults aged 65 or older, with some younger exceptions.

What is Alzheimer’s Disease?

Alzheimer’s is one of the most common types of dementia, with an estimated 6.7 million U.S. cases as of 2023. It is a slow, progressive disease of the brain that impairs memory. It is also characterized by disturbances in:

  • Language
  • Perception
  • Planning
  • Reasoning

 

The causes of Alzheimer’s disease are not fully understood. It is believed that an accumulation of the protein amyloid in the brain plays a role by forming plaque around brain cells. Deposits of another protein, Tau, form tangles within brain cells. Over time, different areas of the brain shrink due to widespread cell death. However, there is much more to be learned. It’s important to note that the treatment and management of Alzheimer’s disease, such as medications or other therapies, may help to slow its progression. However, there is no current cure.

An interesting reality

Per Alzheimer’s Association, seven in ten Americans would want to know early if they have Alzheimer’s disease if it could allow for earlier treatment.

Eye-opening facts about Alzheimer’s & women:

Alzheimer’s Association shares the following statistics:

  • Women are disproportionally affected by dementia.
  • Two-thirds of Americans with Alzheimer’s are women.
  • Older black Americans and older Hispanics are at higher risk.

 

And, as the size of the population grows, so too, will the number and proportion of Americans with Alzheimer’s disease.

Two chilling statistics as it relates to the future:

  • By 2050, the number of people in the U.S. aged 65 and older with Alzheimer’s may grow to a projected 12.7 million, without the development of medical breakthroughs to prevent or cure the disease.
  • Currently, Alzheimer’s and other dementias cost the nation $345 billion. This doesn’t include the value of unpaid caregiving. Absent a cure by 2050, costs for health care, long-term care, and hospice for people with dementia are projected to increase to $1 trillion.

More to know

There are many different types of dementia. Mixed dementia is a combination of two types, the most common of which is Alzheimer’s disease and vascular dementia: the latter generally the result of a major stroke or series of strokes. Some conditions or diseases have overlapping symptoms; thus, a series of medical assessments are required for accurate diagnoses.

Take it seriously

Memory loss that worsens over time or interferes with daily tasks should be medically evaluated. Though people who are at risk of having Alzheimer’s are generally older, the disease is not a normal part of aging. While some memory loss may occur as we grow older, most normal age-related memory loss does not disrupt one’s ability to fully function. Read our related articles.

The need for more studies

Is dementia common? Per WHO, dementia currently affects more than 55 million people worldwide and is more common as people age. In addition, other risk factors such as genetics and estrogen can come into play. Thus, it’s important to study the many pieces of the medical puzzle to see where they fit. This includes gaining further insight into conditions such as high blood pressure, heart disease, diabetes, high blood cholesterol, and more. People should also remain educated on the role a healthy lifestyle can play in guarding against dementia. In the absence of a current cure, there is clearly much more to be learned.

If you or someone you know is experiencing memory loss of concern, do seek prompt medical evaluation.
