It’s common for people to think that dementia and Alzheimer’s are just two different names for the same condition, and, in fact, the two words are often used interchangeably. However, the terms dementia and Alzheimer’s actually have two different and distinct meanings. Here are some pointers to help you differentiate between the two and clear up the confusion:

What is Dementia?

The word “dementia” standing alone is not a specific disease; instead it’s an umbrella term that is used to describe a wide range of common symptoms that impact a person’s cognitive functioning and the ability to perform everyday activities independently. These symptoms may include:

  • Memory decline.
  • A decrease in thinking skills.
  • Poor reasoning and judgment.
  • Increasing lack of attention and focus.
  • Changes in communication and language skills.

A person with dementia is not necessarily suffering from Alzheimer’s. Alzheimer’s is the most common form of dementia, but there are several other kinds, including:

Lewy Body Dementia – caused by abnormal protein deposits in the brain.

Frontotemporal Dementia – as a result of damage to the frontal and temporal lobes of the brain.

Vascular Dementia – resulting from a stroke or another condition that blocks blood flow to the brain.

Parkinson’s Disease Dementia – resulting from progressive deterioration of the nervous system.

Creutzfeldt-Jakob Disease – caused by an abnormal infectious protein in the brain.

Huntington’s Disease – an inherited condition where nerve cells in the brain break down over time.

Mixed Dementia – meaning that the sufferer has more than one type of dementia.

How Many People Have Dementia?

The World Health Organization (WHO) estimated that in 2017 that over 47 million people worldwide were living with some form of dementia. This number is expected to triple by 2050.

How Many People Have Alzheimer’s?

The Alzheimer’s Association states that Alzheimer’s Disease is the cause of as many as 60-80% of all dementia cases globally. This translates to 28-38 million people worldwide.

What are the Risk Factors for Dementia?

The main risk factor for dementia is aging. In fact, up to 50 percent of people ages 85 and up may have some form of dementia. Approximately 33 percent of people over the age of 85 currently have the type of dementia called Alzheimer’s Disease. It is possible to develop dementia at a younger age, but it is much rarer.

What Causes Alzheimer’s?’

The short answer is, we don’t know for sure. Our basic understanding is that Alzheimer’s is a type of brain destruction that may eventually happen alongside aging, and that gets worse over time. Various researchers believe that this process may be accelerated by diminished blood flow, inflammation, excess amyloid protein, toxins, injury, or malnutrition. All of these areas are being worked on by science, and the hope is that eventually, a cure for Alzheimer’s will be found.

What Treatment is Available for Alzheimer’s?

Alzheimer’s disease affects a person’s memory, language, and even their thought-processes. To date, there is no specific treatment that can completely prevent Alzheimer’s Disease. However, research is ongoing, and new ways to help slow symptoms are being developed. Current treatments for Alzheimer’s are aimed at relieving symptoms and could include:

  • Medications to counteract memory loss.
  • Medications to help with behavioral changes or depression.
  • Training to improve cognitive skills.
  • Sleep aids.
