    • Previous publications have shown a high diagnostic sensitivity and specificity of three short clinical rating scales for Alzheimer's disease (AD), frontotemporal dementia (FTD), and vascular dementia (VaD) validated against neuropathological (NP) diagnoses. In this study, the aim was to perform an exploratory factor analysis of the items in these clinical rating scales. The study included 190 patients with postmortem diagnoses of AD (n = 74), VaD (n = 33), mixed AD/VaD (n = 31), or FTD (n = 52). The factor analysis produced three strong factors. Factor 1 contained items describing cerebrovascular disease, similar to the Hachinski Ischemic Score. Factor 2 enclosed major clinical characteristics of FTD, and factor 3 showed a striking similarity to the AD scale. A fourth symptom cluster was described by perception and expression of emotions. The factor analyses strongly support the construct validity of the diagnostic rating scales.

  • The accuracy of short clinical rating scales in neuropathologically diagnosed dementia.
  • 2010
  • Ingår i: The American journal of geriatric psychiatry. - 1064-7481 .- 1545-7214. ; 18:9, s. 810-820

    • Objective: The overall aim was to evaluate to what extent the diagnosis of dementia subtypes, obtained by three clinical rating scales, concurred with postmortem neuropathologic (NP) diagnosis of Alzheimer disease (AD), frontotemporal dementia (FTD), vascular dementia (VaD) and mixed AD/VaD. Design: A prospective longitudinal clinical work-up with postmortem NP examination. Participants: Two hundred nine patients with dementia referred for clinical evaluation and follow-up. Methods: The diagnostic scores in a set of three short clinical rating scales for AD, FTD, and VaD were evaluated against NP diagnoses. Results: The sensitivity and specificity of the AD scale were 0.80 and 0.87, respectively, of the FTD scale 0.93 and 0.92, respectively, and of the Hachinski Ischemic Score (HIS, VaD diagnosis) 0.69 and 0.92, respectively. Cases with mixed AD/VaD generally presented a combination of high AD and ischemic scores. A preferred cutoff score of six was identified for both the AD and FTD scales. Conclusions: All three clinical rating scales showed a high sensitivity and specificity, in close agreement with final NP diagnosis-for the HIS a moderate sensitivity. These scales may thus be considered good diagnostic tools and are recommended for clinical and research center settings.

  • Synapse density related to cerebral blood flow and symptomatology in frontal lobe degeneration and Alzheimer's disease
  • 1999
  • Ingår i: Dementia and Geriatric Cognitive Disorders. - : S. Karger AG. - 1420-8008 .- 1421-9824. ; 10:Suppl 1, s. 64-70
  • Tidskriftsartikel (refereegranskat)abstract
    • In order to evaluate the functional significance of synaptic pathology, synaptic density was quantitated and related to clinical symptomatology and regional cerebral blood flow (rCBF) in 8 patients with frontal lobe degeneration of non-Alzheimer type (FLD) and 19 patients with Alzheimer's disease (AD). Synaptic density was measured in all layers of prefrontal and parietal cortex. The clinical picture of FLD was dominated by a frontal lobe syndrome with changes in personality and behavior, while AD was dominated by temporoparietal symptoms. This parallels the finding of frontal rCBF reductions in FLD patients and temporoparietal reductions in AD patients. Synaptic density was significantly decreased in both FLD and AD, with a regional severity which closely correlated with that of the degeneration, symptomatology and rCBF deficit. The results suggest that synaptic pathology is a likely cause of clinical symptoms and regional metabolic decrement in dementia.
