Did you know nearly 700,000 Californians and 6.5 million Americans are living with Alzheimer’s disease? 

Alzheimer’s vs Dementia: Which Is It?

The terms “dementia” and “Alzheimer’s” are often used interchangeably, but they have very different meanings. 

DEMENTIA:

  • Dementia is the name of a group of symptoms. It is a not a disease per se, but a syndrome that affects cognition function.
  • Dementia is the stage when brain cells are dying, and is usually irreversible.
  • To be called dementia, the symptoms must be severe enough that it disrupts a person’s ability to independently perform activities of daily living. For example, forgetting where you put your car keys once in a while is not dementia.
  • This syndrome is caused by various conditions, such as Alzheimer’s disease, Parkinson’s disease, stroke, depression, Lyme disease, and AIDS.

ALZHEIMER’S:

  • Alzheimer’s disease is a specific brain disorder (falling under the umbrella of dementia) that progressively and irreversibly destroys memory, thinking skills, and affects behavior. 
  • Alzheimer’s disease is named after a German physician, Aloïs Alzheimer, who first described it in 1906.
    Alzheimer’s is characterized by amyloid plaques and tangled bundles of fibers in the brain
  • Alzheimer’s is characterized by two abnormalities: 1) neuron-destroying clumps (amyloid plaques) and 2) tangled bundles of fibers (neurofibrillary tangles or tau) in the brain.
  • Alzheimer’s is the most common form of dementia, accounting for 60 to 80% of dementia cases.

Early Diagnosis is Key

There are many causes for dementia symptoms, which determines how it is treated. 

To diagnose Alzheimer’s, doctors must use a variety of assessments and laboratory measurements since there is no single test that can diagnose Alzheimer’s with 100% accuracy. See KRON 4 | Smell Test to Detect Alzheimer’s
