Kosunen et al. [9], in a prospective study on the diagnostic accuracy of Alzheimer's disease (AD) which included 53 autopsy cases, reported post-mortem diagnoses of definite AD (CERAD criteria/10) in 96% of clinically diagnosed probable AD (NINCDS-ADRDA criteria; n = 28), but in only 14% of clinically possible AD (n = 7), with 56% satisfying the pathological criteria for probable AD [ 10]; another case from this series probably corresponded to the neurofibrillary predominant form of AD [2]. Additional cerebrovascular lesions were seen in 33% of the definite or probable cases of AD. In the group with vascular dementia (VaD) (n = 10), only two cases (20%) were morphologically pure VaD, while the others had some additional AD pathology. In the small sample of mixed dementias (AD+VaD) (n = 6), five (83%) were AD, and 50% lacked cerebrovascular lesions. Four brains or 7.5% of the total showing cortical Lewy bodies were diagnosed as a Lewy body variant of AD (LBV-AD/6). These data on the clinical diagnostic accuracy of AD using standardized clinical and morphological criteria can be largely confirmed by the results of a consecutive autopsy series of elderly demented subjects between 1989 and 1994. This cohort included 269 patients (90 males, 189 females) aged 55-97 years (mean + SD 79.5 + 6.7 years) with a clinical diagnosis of probable or possible AD (DSM-III-R, NINCDS-ADRDRA, ICD.9 criteria); 122 patients (34 males, 88 females) with a mean age at death of 79.4 years were part of the Vienna Prospective Longitudinal Study of Dementia [1, 7] with a psychostatus (Minimental status, MMS) performed not longer than 4-6 months prior to death. The remaining cases were evaluated retrospectively from hospital charts. Neuropathological diagnosis was performed blindly and independently by two skilled neuropathologists using current diagnostic criteria [8, 10, 12], and staging of neuritic AD
