What does AD stand for?

| Type | Initialism |
The initialism AD stands for Alzheimer's Disease in neuroscience and dementia contexts. It names a brain disorder that affects memory and thinking; the letters alone do not diagnose a person.
Alzheimer's disease is one cause of dementia. Definitions in research documents still need checking: NIA's genetics portfolio uses a broader AD definition for some data-sharing criteria, including Alzheimer's disease-related dementias (ADRD). Keep the scope actually defined in the document instead of treating every AD mention as the same clinical or research statement.
Meaning in context
- Alzheimer's
- The disease name commemorates Alois Alzheimer.
- Disease
- The named brain disorder, not a diagnosis made from an abbreviation on this page.
Practical examples
Keep the disease name specific
- Before
AD is just another name for every dementia.
- After
In this context AD means Alzheimer's disease; other causes of dementia need their own identification.
The revised wording keeps a disease and a broader syndrome discussion distinct. It does not identify the cause of an individual's symptoms.
Retain a research label
- Before
ADRD can always be shortened to AD with no change.
- After
Keep AD and ADRD as the source defines them; the added related-dementias wording may change the scope of the discussion.
Research documents can define their scope explicitly. Removing letters without checking that scope can misstate what was studied.
Original illustrative examples, not quotations or reports of actual events.
Use AD with clarity
Does AD mean every type of dementia, or specifically Alzheimer's disease?
See all guidance
Read a research paper
Read the paper's abbreviation definitions and scope. Some NIA data-sharing criteria use AD more broadly to include related dementias.
Use the AD definition actually stated in this research record; do not infer it from the title alone.
Read a care record
Ask the responsible clinician whether the wording is a diagnosis, a concern or a topic being discussed.
What does AD refer to in this particular care note?
Read a broader overview
Keep Alzheimer's disease and related dementias distinct when the source does.
The overview discusses AD and other related dementias.

Documented origin and history
The disease name recalls Alois Alzheimer and the brain observations described in NIA's historical account.
The 1906 milestone concerns the medical account, not proof of the first use of the abbreviation AD.
