The dementia with Lewy bodies (DLB) Consortium has revised criteria for the clinical and
pathologic diagnosis of DLB incorporating new information about the core clinical features
and suggesting improved methods to assess them. REM sleep behavior disorder, severe
neuroleptic sensitivity, and reduced striatal dopamine transporter activity on functional
neuroimaging are given greater diagnostic weighting as features suggestive of a DLB
diagnosis. The 1-year rule distinguishing between DLB and Parkinson disease with …

(DLB), 1 temporal lobe transient slow waves (in the text) or sharp waves (in table 1) on EEG
was reported as a supportive feature for the diagnosis of DLB. The only quoted reference is
a review2 reporting that “standard EEG may show early slowing, epoch-by-epoch
fluctuation, and transient temporal slow-wave activity.” The first reference quoted in the
review3 described EEG recordings in 11 patients with Alzheimer disease (AD) and in 14 …
