Journal article (peer-reviewed)abstract
- 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.

Research review (peer-reviewed)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.

Conference paper (peer-reviewed)abstract
- Objective. The aim was to evaluate cognitive impairments, psychiatric symptoms and cerebral blood flow (CBF) patterns in middle-aged and younger old patients with subjective experience of memory deficits. Methods. The CBF was measured by 99m-Tc-HMPAO-SPECT. The study group was heterogeneous with patients fulfilling criteria for dementia (n=13) and patients with mild cognitive impairment (MCI; n= 24) as well as with not verified cognitive impairment (Non-MCI; n=17). The MCI patients were subdivided into two groups. The MCI type 1 group (n=14) had isolated memory impairments while the MCI type 2 group (n=10) had memory impairments together with slight verbal and/or visuospatial disturbances. Results. The MCI type 1 group showed lower blood flow in the left middle/inferior gyrus and in parts of the left inferior parietal lobe compared to the Non-MCI group. The MCI type 2 group showed reductions in the left anterior medial temporal lobe as well as in parts of the posterior cingulate gyrus. The Non-MCI patients reported high incidence (70%) of long-lasting psychosocial stress. Conclusions. The combination of clinical and CBF data provides diagnostically meaningful information about regional brain dysfunction in patients with memory deficits.
