Biofluid biomarkers of Alzheimer's disease and Lewy body disease and their relationship with cognitive and structural markers
Jurášová, Vanesa ; Veverová, Kateřina (advisor) ; Chmátalová, Zuzana (referee)
The diagnosis of Alzheimer's disease is based on the determination of specific proteins in cerebrospinal fluid (CSF) or their imaging using positron emission tomography. Both methods are invasive and can expose the patient to risk and discomfort. Blood biomarkers, therefore, represent hope for early diagnosis and monitoring of individuals at increased risk of developing Alzheimer's disease. The diploma thesis aimed to determine biomarkers in blood using the ultrasensitive Simoa TM (Single molecular assay) technology and to verify their relationship to the values in CSF. The second aim was to track the relationship between blood biomarkers and cognitive markers of Alzheimer's disease. We demonstrated a positive relationship between serum, plasma, and CSF p-tau 181 concentrations. A negative correlation was observed between the concentrations of p-tau 181 in blood and the results of the MMSE test, which is considered a standard cognitive assessment tool. These findings suggest that plasma and serum p-tau 181 may greatly help the clinical identification of neurodegenerative diseases in primary care. The negative correlation of plasma and serum p-tau 181 with MMSE test results suggests that blood p-tau 181 could be used in population-based studies to detect individuals at high risk of developing...

LC-MS/MS study of phase one in vitro biotransformation of potential drugs against Alzheimer's disease
Kuřátková, Aneta ; Kučera, Radim (advisor) ; Váňová, Nela (referee)
No treatment that would completely stop the progression of Alzheimer's disease has not been found yet. Recently used tacrine showed good results in the treatment of Alzheimer's disease, however long-term use led to chronic hepatotoxicity due to its metabolites. This master thesis deals with the compound 7-phenoxytacrine, one of the promising tacrine derivatives, which is one of the candidates for potential use in the therapy of Alzheimer's disease. Due to the formation of hepatotoxic metabolites of tacrine after the biotransformation in human liver, it appears necessary to identify the emerging metabolites of 7-phenoxytacrine molecule. Within this master's thesis in vitro biotransformation study of 7-phenoxytacrine using human liver microsomes was performed. High performance liquid chromatography with tandem mass spectrometry was used to determine the parent substance and the seventeen 7-phenoxytacrine metabolites. The analytical method showed the formation of six monohydroxylated and eleven dehydroxylated metabolites of 7-phenoxytacrine. Thus, we concluded that hydroxylation is the major metabolic reaction after in vitro microsomal biotransformation. In addition to the identification of metabolites, a quantification and microsomal stability study, including the determination of the amount of...

Comparison of the Montreal Cognitive Assessment and the Mini-Mental State Examination in screening diagnostics of Alzheimer's disease
Orlíková, Hana ; Kulišťák, Petr (advisor) ; Hrachovinová, Tamara (referee)
This thesis deals with the neuropsychological diagnosis of Alzheimer's disease. The aim is to evaluate the psychometric characteristics ofthe new Czech translation of the Montreal Cognitive Assessment (MoCA) by comparison with the Mini-Mental State Examination (MMSE), a method widely used by doctors inscreening diagnostics of Alzheimer's disease. The theoretical part deals with the diagnostics of Alzheimer's disease and mild cognitive impairment. We describe international diagnostic criteria of cognitive disorders and provide an overview of the screening neuropsychological methods most commonly used by Czech specialists. We summarize the current psychometric and psychodiagnostic findings on these methods and focuse on description of MMSE and MoCA. In the empirical part we compare Czech version of MMSE and MoCA-CZ (the new Czech translation of the test). We examined 38 patients with Alzheimer's disease and 70 cognitively healthy seniors. The results show that MoCA-CZ is sufficiently valid and reliable screening method that accurately distinguishbetween healthy subjects and patiens with Alzheimer's disease. We believe that it can enrich screening tools that are available to Czech experts. Key words: Montreal Cognitive Assessment, Mini-Mental State Examination, Alzheimer's disease, psychodiagnostics,...

The selected methods of social work with clients self - non sufficient in health care facilities
Kiliánová, Hana ; Krahulcová, Beáta (advisor) ; Ondrušová, Jiřina (referee)
The main goal of the thesis entitled "The selected methods of social work with clients self-non sufficient in health care facilities" was to describe and to analyze methods used in activation of the elderly suffering from dementia. It draws a comparison of different settings and explores workers's attitude to the methods of activation. The text of the thesis was mapped out into five chapters. The first chapter was set into the context of old age and ageing. The second chapter is concerned with the issues of self-sufficiency and dependency of old age and other related issues. The topic of the third chapter is old age in relation with memory. It defines memory and memory disorders in the elderly suffering from dementia. The fourth chapter is crucial and gives an idea of non-pharmacological and other possible activities which are eligible for application in practice and are intended to reduce cognitive disorders of cognitive functions and behavior disorders. The theoretical part enters into research carried out in four facilities which care for clients with dementia. The research section is represented by a qualitative research where methods of a half structured interview and observation were opted for. The interviews were realized with eight practicing experts. The outcomes gathered from the...

Chronic Patients' Depression
Pečinková, Jana ; Šivicová, Gabriela (advisor) ; Loneková, Katarína (referee)
This thesis "Chronic Patients' Depression" looks into Alzheimer's disease patients' depression. Theoretical part focuses on topics of old age, dementia syndrome, Alzheimer's disease and depression. These topics are described also in their associations. Current researches in the field of study are mentioned too. Practical part deals with presence of depression in Alzheimer's persons. Hypothesis that depression is more frequent in early stage of dementia is tested. In the research there is used standardised method - Yesevage's Geriatric Depression Scale. Other methods which can bring new information is also used (Geriatric Depression Scale filled in by caring persons and structured observation). The outcome is 9,7% Alzheimer's patients suffer from depression. More persons with depression we can find in a group of Alzheimer's early stage however difference between group of early and advanced stage is not significant. This study occupies with assets of other methods for diagnostic of depression.

The relationship between subjective perception of cognitive impairment and objective neuropsychological performance
Marková, Hana ; Kulišťák, Petr (advisor) ; Stehlík, Luděk (referee)
This diploma thesis deals with the topic of Subjective memory complaints (SMC) in elderly population in relation to early diagnostics of Alzheimer's Disease (AD). The term of SMC describes patients with subjective perception of cognitive impairment which is not objectivized during a complex neuropsychological assessment. The character of their subjective complaints has not been thoroughly examined, despite their increased risk to develop cognitive impairment, most likely due to AD (Reisberg, et al., 2008). The aim of this cross-sectional study was to verify the clinical significance of the concept of SMC and to characterize subjective complaints in SMC in comparison to patients with cognitive deficit at the stage of amnestic mild cognitive impairment (aMCI) and in comparison to cognitively healthy elderly (HE). SMC and aMCI patients did not differ in the amount of subjective complaints, but SMC patients reported significantly more complaints compared to HE. The difference in the amount of complaints reported by the patients themselves and by their informants was found neither in aMCI, nor in SMC patients. There were identified questions which may distinguish between SMC and aMCI patients, and questions which may distinguish between SMC patients and HE; that means questions able to distinguish...
