   Sammanfattning : In the thesis, various aspects of deconvolution of ultrasonic pulse-echo signals in nondestructive testing are treated. The deconvolution problem is formulated as estimation of a reflection sequence which is the impulse characteristic of the inspected object and the estimation is performed using either maximum a posteriori (MAP) or linear minimum mean square error (MMSE) estimators.

3. 22. Dementia and Mental Disorders Among the Elderly in Primary Care

   Författare :María Ólafsdóttir; Anders Wimo; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The main pmpose of the present thesis was to investigate how elderly patients with dementia and mental disorders were managed in primary care. The prevalence of the disease was investigated, to what extent the patients and their disorders were detected and treated and the approach of general practitioners toward patients with dementia.

4. 23. Impact of nutritional status and diet on cognitive decline and survival

   Författare :Behnaz Shakersain; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : This doctoral thesis investigated the complex relationship between nutritional status and survival and the impact of dietary intake on cognitive decline in older Swedish adults. The data used in the four studies (I‒IV) in this thesis were derived from the Swedish National Study on Aging and Care in Kungsholmen (SNAC-K). LÄS MER

5. 24. Cardiovascular risk factors, brain structure, and cognitive decline in old age : a population-based study

   Författare :Rui Wang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cardiovascular risk factors;

   Sammanfattning : This doctoral thesis investigated the burden of cardiovascular risk factors among older adults (age ≥60 years) living in central Stockholm (Study I) and the associations of these risk factors with structural brain characteristics and cognitive decline in aging, taking genetic background (APOE gene) into account (Studies II, III, and IV). All studies in this thesis use data from the Swedish National study on Aging and Care in Kungsholmen (SNAC-K) and the embedded SNAC-K Magnetic Resonance Imaging (MRI) study. LÄS MER

7. 25. Mild cognitive impairment neuroimaging markers for early diagnosis of dementia

   Författare :Chaorui Huang; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : This thesis concerns the investigation of mild cognitive impairment (MCI) and Alzheimer's disease (AD) using single photon emission computed tomography (SPECT) and quantitative electroencepholography (qEEG). In study I, The qEEG values were cross-sectionally compared between AD, MCI and controls. LÄS MER
