What is the difference between dementia and Alzheimer's disease?

Thank you, anf all blessings for your insightfull knowledge and and kind heart!!!!

Interesting question. I have wondered also. What is this forgetfulness caused from? I tried to Google this question and received:

Dementia is a broader term referring to a decline in cognitive abilities, while Alzheimer's disease is a specific type of dementia. Alzheimer's disease is the most common cause of dementia. Essentially, Alzheimer's is a disease that causes dementia.
Here's a more detailed breakdown:
Dementia:
This is an umbrella term for a group of symptoms, including memory loss, impaired thinking, and behavioral changes, that interfere with daily life.
Alzheimer's Disease:
This is a specific disease that causes dementia. It's characterized by the progressive destruction of brain cells, leading to cognitive decline.
Other Types of Dementia:
While Alzheimer's is the most common, other types of dementia include vascular dementia, Lewy body dementia, and frontotemporal dementia.
Progression:
Alzheimer's disease is a progressive condition, meaning that symptoms worsen over time.
Causes:
Alzheimer's disease is caused by the build-up of proteins (amyloid plaques and neurofibrillary tangles) in the brain, which disrupts brain cell function.
Symptoms:
Common early symptoms of Alzheimer's include memory loss, particularly for recent events, and difficulty with language and abstract thinking.
No Cure:
Currently, there is no cure for either dementia or Alzheimer's disease, but treatments can help manage symptoms and improve quality of life.

Here are some links with information. It is important to get evaluated and treated as soon as possible to slow down the progression, if possible, through treatment. My mother in law had early onset Alzheimer’s. It gradually caused her brain to die and her body not to function. Sad to watch. My son’s father will be 60 at the end of the month and I am seeing signs in him. Will not be fun to deal with or watch.
