- Clinical vascular features, either as manifest vascular disease or as cardiovascular risk factors were compared in AD with and without neuropathological white matter disease (WMD). The aim of the study was to investigate whether the presence of WMD and the severity of either AD pathology or WMD were associated with different cardiovascular profiles. A total of 44 AD cases were retrospectively studied. All the cases were neuropathologically diagnosed as AD with WMD (n = 22) and as AD without WMD (n = 22), respectively. The patients' medical records were studied with regard to their medical history and to somatic and neurological findings including arrhythmia, congestive heart failure, angina, myocardial infarctions, signs of TIA/stroke, diabetes mellitus, and blood pressure abnormalities, such as hypertension and orthostatic hypotension. In AD-WMD, hypertension, orthostatic hypotension as well as dizziness/unsteadiness were significantly more common than in AD without WMD. Cardiovascular symptoms were more frequent in AD-WMD than in the other group, though the difference did not reach statistical significance. Hypothetically, abnormal and unstable blood pressure levels underlie recurrent cerebral hypoperfusion, which may in turn leave room for the development of WMD. Furthermore, dizziness/unsteadiness may be a symptom reflecting the presence of WMD. (c) 2006 Elsevier Ireland Ltd. All rights reserved.

- We investigated the distribution of neuropathologically defined dementia subtypes among individuals with dementia disorder. The neuropathological reports were studied on all patients (n=524; 55.3% females; median age 80, range 39-102 years) with clinically diagnosed dementia disorder who underwent complete autopsy including neuropathological examination within the Department of Pathology at the University Hospital in Lund, Sweden, during the years 1974-2004. The neuropathological diagnosis was Alzheimer's disease (AD) in 42.0% of the cases, vascular dementia (VaD) in 23.7%, dementia of combined Alzheimer and vascular pathology in 21.6%, and frontotemporal dementia in 4.0% of the patients. The remaining 8.8% of the patients had other dementia disorders, including combinations other than combined Alzheimer and vascular pathology. The registered prevalence of dementia subtypes depends on many variables, including referral habits, clinical and neuropathological judgments and diagnostic traditions, all of these variables potentially changing over time. This, however, does not seem to obscure the delineation of the major dementia subgroups. In this material of 30 years from Lund in the south of Sweden, AD by far dominated among dementia subtypes, while cerebrovascular pathology corresponded with the dementia disorder, either entirely or partly, in almost half of the demented patients.

- Background and purpose Vascular dementia (VaD) has occasionally been associated with cerebral amyloid angiopathy (CAA), but the prevalence and significance of this counterintuitive relationship are poorly known. Therefore, we investigated the presence and characteristics of CAA in brains of VaD cases. Methods We examined temporal and parietal regions of the cerebral cortex of 26 consecutive VaD cases from the Lund Longitudinal Dementia Study. We carried out immunohistochemistry and routine stainings, determined Apolipoprotein E (ApoE) genotypes, and obtained clinical characteristics on the studied group for retrospective analysis. Results CAA was marked in eight out of 26 cases, and correlated strongly with the presence of cortical microinfarcts, both in the temporal lobe and in the parietal lobe. Based on comparisons with eight age-matched VaD cases without CAA, the clinical records suggested that VaD cases with CAA as a group exhibited less pronounced neurological symptoms. A clear contribution of the ApoE genotype could not be identified. Conclusions Based on a combination of the clinical and pathological data, we suggest that microinfarcts in the cerebral cortex associated with severe CAA may be the primary pathological substrate in a significant proportion of VaD cases. Future studies should be undertaken to confirm or dismiss the hypothesis that these cases exhibit a different symptom profile than VaD cases without CAA. Copyright (c) 2006 John Wiley & Sons, Ltd.

Psychiatric Symptoms and Their Psychosocial Consequences in Frontotemporal Dementia.

- Based on a retrospective study of 19 neuropathologically verified cases with frontotemporal dementia (FTD), neuropsychiatric symptoms related to behavioral disturbances and their psychosocial consequences were studied. The results indicate that frontotemporal dementia is often misdiagnosed early in the clinical course. Behavioural features with impaired social interactions, impaired personal regulation, and loss of insight were seen in all patients. The psychosocial consequences reported in this paper challenge future research in frontotemporal dementia.
