Getting a dementia diagnosis what to expect

A dementia assessment involves a detailed history including an account from someone who knows you well, cognitive testing, a physical examination, blood tests to exclude reversible causes, and usually brain imaging. It typically takes more than one appointment.

Quick answer

A dementia assessment involves a detailed history including an account from someone who knows you well, cognitive testing, a physical examination, blood tests to exclude reversible causes, and usually brain imaging. It typically takes more than one appointment.

The first appointment

Bring someone who knows you well, because their observations are often the most valuable part of the history and the person experiencing the changes has usually adapted around them. Expect questions about what changed, when, and in what order, since the sequence distinguishes dementia types. There will be cognitive testing, which most people find uncomfortable; it is a measurement rather than an examination you can fail, and knowing that in advance helps. A physical and neurological examination follows.

The investigations

Blood tests look for contributors that are treatable, including thyroid function, vitamin B12 and metabolic abnormalities. A full medication review matters particularly, since several common drugs impair cognition and the total number taken is itself a factor. Brain imaging is usually arranged, performed at an imaging centre since these offices have no imaging suite, and the report is reviewed here. Where a specific answer would change decisions, biomarker testing may be discussed; it is arranged externally and interpreted alongside everything else.

Getting the answer, and what follows

Results are usually discussed at a follow-up rather than the first visit. The answer may be a specific diagnosis, mild cognitive impairment, or that no dementia is present and something else explains the changes. All three are real outcomes. Ask what the diagnosis rests on, what would change it, and when you should be seen again, because a diagnosis with no stated review interval leaves families managing alone. Bring someone to that appointment too, since it contains more information than anyone retains.

Frequently asked

Questions about getting a dementia diagnosis what to expect

What happens during a dementia assessment?
A detailed history including an account from someone close to you, cognitive testing, a physical and neurological examination, blood tests for reversible causes, and usually brain imaging. It generally takes more than one appointment. Cognitive testing is a measurement rather than an examination you can fail, and knowing that in advance makes it easier.
Should I bring someone with me?
Yes. Their account of what has changed and over what period is frequently the most informative part of the assessment, because people living with cognitive change often adapt around it without registering it. If nobody can attend, a written note of what they have observed and over what period is the next best thing.
What reversible causes are checked?
Thyroid disease, vitamin B12 deficiency, metabolic abnormalities, sleep disorders, depression, alcohol and medication effects. Finding one of these is a far better outcome than a biomarker result, which is why the screen is not a formality. A full medication review matters particularly, since the total number taken is itself a factor independent of which drugs they are.
How long does it take to get an answer?
Usually more than one appointment, because investigations are arranged between visits. Imaging is performed at an external centre since these offices have no imaging suite, and the report is then reviewed with you here. Bring someone to the results appointment too, since it contains more information than most people retain in one sitting.
What if the diagnosis is not dementia?
That is a common and genuine outcome. Mild cognitive impairment, depression, sleep disorders and medication effects all produce similar complaints. Knowing which applies changes what happens next, which is the purpose of the assessment. Ask what the diagnosis rests on and what would change it, since that question tends to produce a more useful answer than asking whether it is certain.
