- The aim of this study was to evaluate cognitive impairment, psychiatric symptoms and cerebral blood flow (CBF) patterns in middle-aged (35–64 years) and younger old patients (65–74 years) with subjective experience of memory deficits. The study group was heterogeneous with patients fulfilling criteria for dementia, as well as patients with mild cognitive impairment (MCI) and with non-verified cognitive impairment (non-MCI). Seventy per cent of the non-MCI patients reported long-lasting experiences of psychosocial stress tentatively causing the memory problems. The MCI patients were subdivided into two groups: MCI type 1 included patients with isolated memory impairment, while MCI type 2 included patients with memory impairment together with slight verbal and/or visuospatial impairments. CBF measurements comparing the two MCI groups with the non-MCI group were performed. The MCI type 2 showed reduced CBF in the left anterior medial temporal lobe as well as in parts of the posterior cingulate gyrus. The CBF pattern in MCI type 2 concurs with the pathophysiological process of Alzheimer’s disease. The results indicate that it is important to make a subdivision of MCI patients regarding the presence of isolated memory impairments or memory impairments together with other slight cognitive deficits.

- The aims were to evaluate the cognitive performance and clinical diagnosis in patients (<75 years) seeking help for subjective memory complaints, to determine the prevalence of certain psychiatric symptoms and to conduct follow-up examinations. At baseline 41% showed normal cognitive performance (subjective memory impairment; SMI), 37% fulfilled criteria for mild cognitive impairment (MCI) and 22% were classified as dementia. There were significant associations between the three groups and experiences of psychosocial stress and feelings of anxiety. The proportion of psychosocial stress was significantly higher in SMI vs. MCI and SMI vs. dementia. Feelings of anxiety were significantly higher in SMI vs. MCI. At the 3-year follow-up, 88% of the SMI patients remained stable SMI and 60% of the MCI patients remained stable. There was a significant reduction of psychosocial stress and moderate reduction of feelings of anxiety among the SMI patients. The findings indicate that the risk of patients with SMI developing dementia is small within a 3-year span. We propose that subjective memory complaints might be influenced by the presence of psychosocial stress and feelings of anxiety disturbing the memory processes and interfering with the patients' evaluation of their memory function.

Forskningsöversikt (refereegranskat)abstract
- Organic dementia is dominated by primary degenerative disorders such as Alzheimer’s disease (AD) and frontotemporal dementia (FTD). FTD is a distinct clinical syndrome with behavioural, personality, emotional and language disturbances preceding the cognitive decline. This clinical presentation is distinctly different from that of AD which is characterized by early cognitive changes, such as memory impairment, aphasia and apraxia, and a relatively preserved personality and behaviour. The differences between these two conditions reflect the predominant topographic distribution of brain pathology. The differences in clinical profiles and treatment strategies will be highlighted. In both disorders loss of functional ability, development of behavioural disturbances and dependency impose heavy demands on family and other caregivers. This presentation will concentrate on early recognition and diagnosis, using systematic clinical evaluation, neuropsychological testing and different brain imaging methods. This is important for a successful development of therapeutic strategies for both cognitive and behavioural symptoms in FTD and AD.

Psychiatric Symptoms and Their Psychosocial Consequences in Frontotemporal Dementia.
- 2005

Ingår i: Alzheimer Disease and Associated Disorders. - 0893-0341. ; 19 Suppl 1, s. 15-18

Tidskriftsartikel (refereegranskat)abstract
- 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.
