The words "screening", "risk insight" and "diagnosis" are sometimes used as if they mean the same thing. They do not, and the difference matters, especially for a sensitive area like dementia.
What screening means
Screening generally refers to checking for early signs of a condition in people who may not have obvious symptoms. Screening can flag that something may be worth a closer look, but it does not, by itself, confirm a condition.
What diagnosis means
A diagnosis is a clinical conclusion, made by qualified professionals, usually after assessment, history-taking and sometimes tests. Diagnosing dementia is a careful process that considers many factors, and it is something only clinicians can do.
Where risk insight sits
Some tools, including DementiaDetect, are being developed to offer risk insight: a signal that patterns may be worth attention. This is different again from both screening and diagnosis. Risk insight is supportive information that may help someone decide whether to seek assessment. It is not a verdict, and it does not replace clinical judgement.
The clinical pathway
If a concern is raised, whether by a person, a family or a tool, the appropriate next step is usually a conversation with a GP, who can advise on assessment and, where helpful, refer to specialist services such as a memory clinic.
Why the distinction matters
Treating a signal as a diagnosis can cause unnecessary worry, or false reassurance. That is why DementiaDetect is careful to describe exactly what it does and does not do. You can read more on our Responsible AI page.
Key takeaways
- Screening checks for early signs; it does not confirm a condition.
- Diagnosis is a clinical conclusion that only qualified professionals can make.
- Risk insight is supportive information, not a screen and not a diagnosis.
- If a concern is raised, the right next step is a conversation with a GP.
