Umbrella

What may the Dementia Umbrella include?

Depending on the Source (DotS) this Umbrella may include:

  • Alzheimer’s Disease (AD)
  • Dementia
  • Lewy Body Dementia
  • Mixed Dementia
  • Vascular Dementia

Terminology

Is dementia an umbrella term?

In About Alzheimer’s & Dementia: What Is Dementia? Alzheimer’s Disease International (ADI) also note:

“Dementia is an umbrella term for a collection of symptoms that are caused by disorders affecting the brain and impact on memory, thinking, behaviour and emotion”.2

Definition

What is dementia?

DotS the definition of dementia may vary. The (United States) National Institute on Aging’s (NIA) definition is:

“Dementia is the loss of cognitive functioning — thinking, remembering, and reasoning — to such an extent that it interferes with a person’s daily life and activities”.3

The World Health Organization’s (WHO) definition is:

“Dementia is a syndrome that can be caused by a number of diseases which over time destroy nerve cells and damage the brain, typically leading to deterioration in cognitive function (i.e. the ability to process thought) beyond what might be expected from the usual consequences of biological ageing. While consciousness is not affected, the impairment in cognitive function is commonly accompanied, and occasionally preceded, by changes in mood, emotional control, behaviour, or motivation”.4

Symptoms

What may be symptoms of dementia?

In About Alzheimer’s & Dementia: What Is Dementia? the ADI elaborate on:

“The specific symptoms a person living with dementia experiences will depend upon what parts of the brain are affected and/or the specific disease that is causing their dementia. Symptoms may include:

  • Loss of memory
  • Difficulty in finding the right words or understanding what people are saying
  • Difficulty in performing previously routine tasks
  • Personality and mood changes”.5

Aging

Is dementia a normal part of aging?

According to the WHO:

“Although age is the strongest known risk factor for dementia, it is not an inevitable consequence of biological ageing”.6

Cause

What may cause dementia?

In Dementia: Key Facts the WHO explain:

“Dementia results from a variety of diseases and injuries that primarily or secondarily affect the brain”.7

Alzheimer’s Disease

What is the association between Alzheimer’s Disease and dementia?

In Dementia: Key Facts, dated 15 March 2023, the WHO note:

“Alzheimer’s disease is the most common form of dementia and may contribute to 60-70% of cases”.8

Women

In women, how common is dementia?

In Dementia: Key Facts the WHO note:

  • “Women are disproportionately affected by dementia, both directly and indirectly. Women experience higher disability-adjusted life years and mortality due to dementia, but also provide 70% of care hours for people living with dementia”.9

Menopause

Is there an association between menopause and dementia?

In Menopause FAQs: Menopause Symptoms – Q. My memory is just not as good as it used to be, and it’s really bothering me. Does menopause cause this? Will it ever get better? the North American Menopause Society elaborate on:

“A. Memory and other cognitive abilities change throughout life. Difficulty concentrating and remembering are common complaints during perimenopause and the years right afterward. Some data imply that even though there is a trend for memory to be worse during the menopause transition, memory after the transition is as good as it was before. Memory problems may be more related to normal cognitive aging, mood, and other factors than to menopause or the menopause transition”.10

Prevention

How may dementia be prevented?

In Brain Health the (United States) Alzheimer’s Association explain:

“Research is still evolving, but evidence is strong that people can reduce their risk of cognitive decline by making key lifestyle changes, including participating in regular physical activity, staying socially engaged, and maintaining good heart health”.11

Health Care Provider

What if I would like reassurance I do not have dementia?

If you would like reassurance you do not have dementia, it may be in your best interest to choose to talk to your health care provider about this.

In Dementia: About Dementia – What Is Dementia the (United Kingdom) NHS also note:

“It’s normal for your memory to be affected by stress, tiredness, certain illnesses and medicines. But if you’re becoming increasingly forgetful, particularly if you’re over the age of 65, it’s a good idea to talk to a GP about the early signs of dementia”.12

Who is a GP?

DotS and/or DotC (Depending on the Country) a GP may be a qualified and registered general practitioner, a medical practitioner, a medical doctor or a doctor.
