Re: Suspected early dementia
I recently read the article by Jonathan M Schott on suspected early dementia (BMJ 2011; 343: d5568 doi: 10.1136/bmj.d5568.
I noticed that HIV testing and TPHA screening were not mentioned in the routine work up.
I therefore went to the NICE guidelines:
“Testing for syphilis serology or HIV should not be routinely undertaken in the investigation of people with suspected dementia. These tests should be considered only in those with histories suggesting they are at risk or if the clinical picture dictates”. This is indeed in agreement with the Dutch guidelines.
I wonder on what evidence this is based on how one ever can state that someone has no history suggesting that they are at risk!
This is especially important since we have seen patients in their 50s diagnosed with Alzheimer’s disease who have recovered after treatment for neurosyphilis.
We have seen men and women misdiagnosed with HIV as well.
So I think that the work up in everyone (especially between 50-80) with a diagnosis of dementia shpu;d include HIV and TPHA testing.
