- All vascular dementia (VaD) cases, neuropathologically verified in a longitudinal prospective dementia project, were classified according to the vascular brain lesion type and related to the dementia type and cardiovascular pathology. From 1976 to 1995, there were 175 VaD cases, 49 of which were pure, without Alzheimer pathology and only one type of cerebrovascular lesion. Furthermore, it was found that 6 cases suffered hypoxic hypoperfusive disease, while 7 were found to have large vessel disease and 36 small vessel disease. In addition to Alzheimer pathology, more than one type of vascular brain pathology was found in the remaining 126 cases. In these cases, diagnosed in accordance with the predominant type of VaD, hypoxic-hypoperfusive lesions were found in 55, large vessel lesions in 50 and small vessel lesions in 110 cases. It should be stressed that 87% of all cases with hypoxic hypoperfusive lesions also had Alzheimer pathology. Cardiovascular and aortic pathologies were more prevalent in small vessel dementia than in the other VaD groups. Clinically diagnosed arterial hypertension was significantly associated with small vessel dementia, but not with hypoxic-hypoperfusive dementia. Cardiovascular symptoms varied considerably in frequency between different dementia groups. VaD is a heterogeneous group regarding lesions caused by different pathophysiological mechanisms and with different combinations of brain pathologies. It is therefore necessary to identify the various types of vascular brain lesions for a correlation with clinical symptoms and for diagnostic purposes in the search for risk factors and therapeutic strategies.

Journal article (peer-reviewed)abstract
- 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.

Vascular dementia - classification and clinical correlates

Doctoral thesis (other academic/artistic)abstract
- During the period (1976-1995) a total of 175 consecutive patients (m 88/f 87) with neuropathologically verified vascular dementia (VaD) were examined. 22 patients with pure Alzheimer's Disease (AD) were also studied. All patients were diagnosed and followed at the Department of Psychogeriatrics (Lund University Hospital). The neuropathological examination revealed VaD, sometimes with additional contribution of Alzheimer pathology. The cases were classified as Large Vessel Dementia (LVD), Small Vessel Dementia (SVD) and Hypoperfusive Hypoxic-ischemic Dementia (HHD). The mean age at death was 80 years (range 54-100) and almost identical in the three groups.The results show that VaD is neuropathologically heterogeneous, characterized by one, two or all three types of vascular pathology. The majority of cases (126/175), showed more than one type of brain pathology (vascular or in combination with Alzheimer pathology). There was a large coexistence with Alzheimer pathology (65% of the total 175 cases). 49 cases were pure, with only one type of vascular pathology. SVD was the largest pure group (21% of the total 175 cases). Post mortem verified heart pathology, was twice as common in SVD as in LVD and HHD.Cardio-cerebrovascular features (arrhythmia, congestive heart failure, cardiac infarction, hypertension, orthostatic hypotension and TIA/stroke) were more common in LVD and SVD, than in HHD. The coexistence of Alzheimer pathology did not change these results.Dizziness and unsteadiness or falls were reported in 102 of the 175 VaD patients. Dizziness correlated with hypertension and orthostatic hypotension while unsteadiness correlated only with hypertension. Falls correlated strongly to the use of neuroleptics and hypnotics.Hallucinations/delusions and delirium were reported in many patients and most common in the groups with pure LVD, pure SVD and especially in the SVD with combined Alzheimer pathology.Cardio-cerebrovascular features were more common in patients with AD combined with white matter pathology than those with pure AD. This study illustrates the neuropathological and clinical heterogeneity in VaD. This is of great importance for the understanding, treatment and care of the individual suffering from VaD.

Book chapter (other academic/artistic)abstract
- Purpose – This chapter examines the developmental journey toward a sustainable health care system in the West of Skaraborg County in Sweden from 2008 to the present by proposing and illustrating the concept of a clinical microsystem to capture the work of a mobile team to care for elderly people with multiple diseases in its embedded context. Design – An action research approach was adopted that entailed four researchers, one of whom was also a health care practitioner, engaging in iterative dialogues with the mobile team. This aimed at catalyzing joint learning in repeated action-reflection cycles at least three times a year over a period of 3 years. Data from patient databases were also drawn upon as additional resources for reflection. Findings – The outcome of the initial periods of the team’s work in the microsystem dramatically improved the care of these patients, significantly increasing quality of life and stabilizing their medical situation. It has also led to decreased resource utilization, not just by the team, but elsewhere in the wider health system. Originality/value – We draw on and develop the concept of clinical microsystems to argue that such systems have a team at their core, but their work practices and patient outcomes require us to look beyond the team itself and take into account its interactions with patients and actors in the wider health care system. We also draw on the framework of Christensen, Grossman, and Hwang (2009) to propose that each microsystem has three distinct value configurations, namely shops, a chain, and a network. In terms of design, we suggest that the clinical microsystem can be seen as a parallel learning structure to that of the established health care bureaucracy.
