So when you’re looking at these symptoms, certain symptoms may suggest that you have an Alzheimer’s problem, particularly if it’s a short-term memory problem, whereas other symptoms, for example, if you have very inappropriate, rude, difficult behavior, then that may suggest another problem like a frontal lobe dementia.
The type of symptoms you have may lead us to understand what kind of dementia you may be experiencing. When you evaluate somebody, we use a number of different tests. Typically, when somebody has milder symptoms, we use a more demanding test, something such as the Montreal Cognitive Assessment, which is much more useful than the test that most regular doctors are familiar with, which is the Mini Mental Status Evaluation, or the MMSE.
So we do encourage family doctors to use the tougher test when they first see somebody who is concerned and complained. Otherwise they will often miss patients who have early concerning symptoms.
The other things that we do for evaluating patients with dementia are certain blood tests to make sure there isn’t a thyroid problem, or difficulty with your low B12 level. We also often do a brain scan to make sure that we’re not missing some other cause for dementia besides a problem like Alzheimer’s disease.
If you’re concerned that you have any of these symptoms or somebody close to you has any of these concerning behavior or cognitive problems, then the starting point really is with your family doctor.
Your family doctor can do some initial testing with you, and if your symptoms, or your family member’s symptoms, are concerning, they may want to send you on to see a specialist for further testing.
