Abstract

Background

Dementia with Lewy bodies (DLB) and Creutzfeldt‐Jakob disease (CJD) share clinical features like cognitive decline, motor disturbances en psychiatric symptoms. Overlapping symptoms may cause physicians to mistake DLB for CJD.

Methods

Clinical data of 12 patients with autopsy‐confirmed DLB who had been clinically suspected to suffer from CJD were analysed to investigate possible clinical features which led to misdiagnosis.

Results

There was an association in time between administering neuroleptics and rapid clinical deterioration in 8 out of 9 patients.

Conclusion

It is suggested that the neuroleptic sensitivity in LBD fuelled the misdiagnosis of CJD in the presented series. Diagnostic confusion between CJD and DLB may have important clinical consequences and may lead to treatment restrictions. Copyright © 2006 John Wiley & Sons, Ltd.
