Short answer: they are not the same
Dementia is an umbrella term for a group of symptoms (loss of memory, judgment, and reasoning). Alzheimer's is the most common cause of that dementia. All Alzheimer's leads to dementia, but not all dementia is Alzheimer's. The World Health Organization estimates Alzheimer's accounts for 60% to 70% of cases.
In one line: dementia is the category and Alzheimer's is the most common cause within it. Dementia is a syndrome; Alzheimer's is a specific brain disease. Some causes of dementia are reversible; Alzheimer's is not, though treatment slows it and supports care.
What is dementia
Dementia is not a single disease or a normal part of aging. It is a decline in cognitive function (memory, language, orientation, planning) severe enough to affect daily life. The most common types are:
- Alzheimer's, the most common.
- Vascular, from reduced blood flow to the brain, often after a stroke.
- Lewy body, with hallucinations and stiffness similar to Parkinson's.
- Frontotemporal, which affects behavior and language before memory.
What is Alzheimer's disease
Alzheimer's is a neurodegenerative disease: brain cells are progressively damaged and die from abnormal protein buildup. It begins with forgetting recent events and, over years, moves toward trouble with speech, orientation, and everyday tasks. There is no cure, but an early diagnosis allows symptom treatment, planning, and a better quality of life.
In Medellin we work with experienced neurologists. One of our allied doctors, Dr. Francisco Lopera, a world reference in Alzheimer's research, received the Potamkin Prize for his work.
"Senile dementia": why the term is outdated
For years "senile dementia" implied that memory loss was an inevitable part of old age. Aging does not cause dementia. The term is obsolete because it blurred normal aging with a medical condition that has specific causes and deserves a diagnosis. If you search for "senile dementia," you are really looking for information about dementia and its causes, such as Alzheimer's.
Early signs: when to seek help
See a doctor when these appear persistently:
- Memory lapses that disrupt daily life (appointments, recent conversations).
- Trouble planning, following a recipe, or handling money.
- Confusion about time or place.
- Difficulty finding words or following a conversation.
- Mood changes, apathy, or unexplained distrust.
Forgetting a name now and then is not a red flag. A sustained pattern that affects independence is.
When home care is no longer enough
Dementia progresses. Over time, home care can fall short of what the person needs: constant supervision, trained staff, and a safe environment. Many families reach that point and look for specialized support.
In Colombia there are geriatric homes with teams trained in dementia and Alzheimer's care. At Hogares Geriatricos you can browse a directory of homes for older adults by city and compare options by the level of care the person needs.
Colombia and elder care
More Colombian families and older adults from abroad are considering Colombia for elder care. The reasons are concrete: residential care costs less than in North America or Europe, there is cultural proximity for the Latino community, and the supply of homes and medical care is growing. For those coming from abroad, combining specialized medical care with residential care is workable. At MDE Care we support that process with personalized guidance.
