Dementia and Alzheimer's: Understanding the Difference
Dementia is a term for a group of symptoms affecting abilities such as memory, thinking and everyday tasks. Alzheimer’s disease is one cause of dementia. Understanding that distinction can help families find suitable information and support.
Why the distinction matters
The words are often used together, but they are not identical. The person’s diagnosis and needs should be discussed with their healthcare team rather than inferred from a general article.
Focus on everyday needs
Support may involve communication, dressing, meals, activities or personal care. The assistance needed can change over time and can differ between people with the same diagnosis.
Choose products for a task
If the difficulty is getting dressed, compare garment openings and fastenings. If the difficulty is a meal, consider the table setup and appropriate eating aids. Selecting by a practical need is more useful than assuming one product suits everyone with dementia.
Get trustworthy information
Use established health and dementia organisations for diagnosis and treatment information. Speak to a GP about new symptoms or concerns, and seek support for carers as well as the person.
