Abstract: Dementia with Lewy Bodies (DLB) accounts for approximately 20 % of all autopsy-confirmed dementias in the elderly. Presumably, DLB is underdiagnosed in patients without or with only mild Parkinsonian symptoms in the daily routine of memory clinics. This motivated the Austrian Alzheimer Society and the Austrian Parkinson Society to inform about core features, suggestive features and supportive clinical findings of DLB and to provide information on diagnostic possibilities leading to better differential diagnosis. We also guide in the management of DLB as pharmacological treatment can pose difficult dilemmas for the treating clinician.

Abstract: We assessed the accuracy of clinical diagnosis of progressive supranuclear palsy (PSP, Steele-Richardson-Olszewski disease) and the validity of existing sets of clinical diagnostic criteria for PSP (see Appendix) using neuropathologically examined cases from the Queen Square Brain Bank for Neurological Disorders. Diagnosis of PSP was made by 40 different physicians, and 60 cases clinically diagnosed as PSP when last assessed in life were studied. In 47 cases (78%), the diagnosis of PSP was confirmed pathologically. False-positive diagnoses included Parkinson's disease with significant additional cortical Lewy body (n = 3) or Alzheimer (n = 1) pathology, multiple system atrophy (n = 4), and corticobasal degeneration, Pick's disease, motor neurone disease, cerebrovascular disease, and a sporadic case of frontotemporal dementia and parkinsonism linked to chromosome 17 (1 case each). Most cases of PSP were diagnosed accurately by neurologists at the final assessment. Although application of National Institute of Neurological Disorders and the Society for PSP possible category marginally improved the accuracy of initial clinical diagnosis, none of the existing operational criteria could significantly improve accuracy of the final clinical diagnosis.
