Simpson et al (Psychiatric Bulletin, November 2005,
29, 410-412) state in their audit of the use of cholinesterase
inhibitors that stopping these drugs in the latest stages of dementia
is poor clinical practice and likely to have adverse outcomes.
They base this opinion on the fact that many of the patients in their sample
deteriorated or died after their memory enhancers were discontinued when their
Mini-Mental State Examination scores fell below 12. The authors acknowledge
that this high death rate could be because the patients who deteriorated or
died were probably the most physically ill. In fact, this would be the
simplest and most likely explanation. Therefore, the conclusion that stopping
these drugs in the advanced stages of dementia constitutes poor clinical
practice is really unfounded and could only be supported after the hypothesis
is tested successfully in a controlled trial.
