Full textDemens är ett syndrom av sjukdomar som orsakar kognitiv nedsättning och påverkar både de drabbade och deras familjer. Den vanligaste typen av demens ar Alzheimers sjukdom, med cirka 10 miljoner nya fall per ar. I denna studie undersöker vi olika maskininlärningsmodeller och tillvägagångssätt i syfte att underlätta får sjukvårdspersonal att ställa en tidig diagnos, och möjligtvis att även kunna automatisera vissa delar av diagnosprocessen. Vi utvärderar vara modeller på Pittcorpuset i DementiaBank-datasetet och använder 10-delad korsvalidering. Vi jämför två transformer-modeller: BERT och RoBERTa, och finner att bada modeller åstadkommer goda resultat avseende noggrannhet, precision, specificitet och sensitivitet. Den högsta noggrannheten uppnås av RoBERTa, på 86.72%, en precision på 90.69%, och en specificitet på 90.53%. Vidare undersöker vi gångbarheten i att använda automatisk taligenkänning for automatiserad transkribering av ljudinspelningar från patientmoten. RoBERTa uppnår da en noggrannhet på 83.59% när den använder transkriberad text från Googles automatiska taligenkänningstjänst, vilket tyder på att sådana metoder kan vara gångbara for att automatisera vissa delar av den diagnostiska processen. Förutom undersökning av transformermodeller bidrar detta verk även med en marknadsanalys av marknadspotentialen får ett verktyg får automatiserad demensdiagnostik. Analysen baseras på en litteraturstudie och två intervjuer; en med en VD får en start-upp som erbjuder liknande tjänster, och en intervju med en forskare inom demens. Med litteraturstudien och de två intervjuerna som grund analyserar vi marknadspotentialen med tre ramverk: Porters fem krafter, PEST-analys och SWOTanalys. Vi fastslår att det trots flertal hinder och svårigheter får marknadsinträde finns det stor potential och en stor efterfrågan på en sådan produkt.

Full textThe concept of appearance in ABC represents the union of intensity and shape information extracted from magnetic resonance images (MRI). The classification method relies on a linear modeling of appearance features via principal components analysis, and comparison of the distribution of projection coordinates for the populations under study within a reference multidimensional appearance eigenspace. Classification is achieved using forward, stepwise linear discriminant analyses, in multiple cross-validated trials. In this work, the ABC methodology is shown to accurately lateralize the seizure focus in temporal lobe epilepsy (TLE), differentiate normal aging individuals from patients with either Alzheimer's dementia (AD) or Mild Cognitive Impairment (MCI), and finally predict the progression of MCI patients to AD. These applications demonstrated that the ABC technique is robust to different signal changes due to two distinct pathologies, to low resolution data and motion artifacts, and to possible differences inherent to multi-site acquisition.
The VBC technique relies on voxel-based morphometry to identify regions of grey and white matter concentration differences between co-registered cohorts of individuals, and then on linear modeling of variables extracted from these regions. Classification is achieved using linear discriminant analyses within a multivariate space composed of voxel-based morphometry measures related to grey and white matter concentration, along with clinical variables of interest. VBC is shown to increase the accuracy of prediction of one-year clinical status from three to four out of five TLE patients having undergone selective amygdalo-hippocampectomy. These two techniques are shown to have the necessary potential to solve current problems in neurological research, assist clinical physicians with their decision-making process and influence positively patient management.

Full textNowadays it is still difficult to perform an early and accurate diagnosis of dementia, therefore many research focus on the finding of new dementia biomarkers that can aid in that purpose. So scientists try to find a noninvasive, rapid, and relatively inexpensive procedures for early diagnosis purpose. Several studies demonstrated that the utilization of spectroscopic techniques, such as Fourier Transform Infrared Spectroscopy (FTIR) and Raman spectroscopy could be an useful and accurate procedure to diagnose dementia. As several biochemical mechanisms related to neurodegeneration and dementia can lead to changes in plasma components and others peripheral body fluids, blood-based samples and spectroscopic analyses can be used as a more simple and less invasive technique. This work is intended to confirm some of the hypotheses of previous studies in which FTIR was used in the study of plasma samples of possible patient with AD and respective controls and verify the reproducibility of this spectroscopic technique in the analysis of such samples. Through the spectroscopic analysis combined with multivariate analysis it is possible to discriminate controls and demented samples and identify key spectroscopic differences between these two groups of samples which allows the identification of metabolites altered in this disease. It can be concluded that there are three spectral regions, 3500-2700 cm -1, 1800-1400 cm-1 and 1200-900 cm-1 where it can be extracted relevant spectroscopic information. In the first region, the main conclusion that is possible to take is that there is an unbalance between the content of saturated and unsaturated lipids. In the 1800-1400 cm-1 region it is possible to see the presence of protein aggregates and the change in protein conformation for highly stable parallel β-sheet. The last region showed the presence of products of lipid peroxidation related to impairment of membranes, and nucleic acids oxidative damage. FTIR technique and the information gathered in this work can be used in the construction of classification models that may be used for the diagnosis of cognitive dysfunction.
Atualmente, não é possível fazer um diagnóstico precoce e diferencial da doença de Alzheimer, deste modo, é necessário encontrar biomarcadores que o permitam. Para isso, os cientistas tentam encontrar um procedimento nãoinvasivo, rápido, e relativamente barato. Os resultados de vários estudos demonstraram que a utilização de técnicas espectroscópicas, tais como a Espectroscopia de Infravermelho Transformada de Fourier (FTIR) e / ou espectroscopia de Raman, podem ser ferramentas úteis para diagnosticar a DA. Uma vez que, na DA, alguns mecanismos bioquímicos podem levar a mudanças em componentes do plasma, podem então ser utilizadas amostras de sangue nas análises espectroscópicas o que torna a técnica simples e menos invasiva. Com este trabalho pretende-se confirmar algumas das hipóteses de estudos anteriores em que o FTIR foi usado no estudo de amostras de plasma de possíveis doentes com DA e respetivos controlos e verificar a reprodutibilidade desta técnica espectroscópica na análise deste tipo de amostras. Através da análise espectroscopia combinada com análise multivariada é possível discriminar as amostras controlos e dementes e identificar as principais diferenças espectroscópicas entre estes dois grupos de amostras que permitem identificar os metabolitos alterados nesta patologia. Pode-se concluir que existem três regiões espectrais, 3500-2700 cm-1, 18001400 cm-1 e 1200-900 cm-1 onde se pode extrair informação espectroscópica relevante. Na primeira região, a principal conclusão que é possível tirar é que há um desequilíbrio entre o teor de lípidos saturados e insaturados. Na região entre 1800-1400 cm-1, é possível observar a presença de agregados de proteínas e a alteração na conformação das proteínas para folha β paralela altamente estável. A última região revelou a presença de produtos de peroxidação lipídica relacionados com a insuficiência de membranas, e danos oxidativos nos ácidos nucleicos. A técnica de FTIR e a informação reunida neste trabalho pode ser utilizada na construção de modelos de classificação que possam vir a ser utilizados para o diagnóstico de disfunções cognitivas.

Full textA South African family of Mixed Ancestry presented with a rapidly progressive dementia and a movement disorder which affected a number of individuals across three generations. The initial symptoms included personality changes and tremors that escalated to severe dementia and eventually a completely bedridden state. It was determined that the mean age at onset was in the third decade of life and affected individuals died within 10-15 years after the onset of symptoms. The aim of the present study was to elucidate the genetic cause of the disorder in this family and to further investigate the patho-biology of the disease. Mutations that could possibly cause the observed phenotype in this family were screened for. These included loci implicated in Huntington’s disease, Parkinson’s disease, Dentatorubral-Pallidoluysian Atrophy, Spinocerebellar ataxias (types 1, 2, 3, 6, and 7), Huntington’s disease-like 2 (HDL2) and several mitochondrial disorders. Single-strand Conformation Polymorphism (SSCP) analysis and direct sequencing were used to detect possible mutations while genotyping on an ABI genetic analyser was used to detect disorders caused by repeat expansions. Haplogroup and Short Tandem Repeats (STRs) analyses of the Y-chromosome and mitochondrial DNA of one affected family member was used to determine the family’s genetic ancestry. Reverse transcriptase polymerase chain reaction (RT- PCR) and complementary DNA (cDNA) analyses of the Junctophlin-3 (JPH3) gene was performed to provide information on the expression profile of this gene. After the exclusion of several genetic loci it was shown that this family had HDL2. This is a rare disease caused by a CAG/CTG repeat expansion in an alternatively spliced version of the JPH3 gene. HDL2 occurs almost exclusively in individuals of Black African ancestry. The genetic ancestry data suggested that the family member was most likely of South African Mixed Ancestry making this the first reported family of South African Mixed Ancestry with HDL2. A pilot study investigated the repeat distribution amongst three South African sub-populations in order to determine whether there was a bias in the repeat distribution that possibly predisposes Black Africans to develop the disease. The results showed a statistically significant difference (P= 0.0014) in the distribution of the repeats between the Black African and Caucasian cohorts. However, no conclusions could be drawn as to whether Black Africans harboured larger repeats that predisposes them to developing HDL2. The expanded repeat is located in an alternatively spliced version of the JPH3 mRNA. Interestingly, this repeat is not present in the mouse homologue of the gene although the rest of the genomic sequence is highly conserved across the human, mouse and chimpanzee genomes. Using foetal brain cDNA and PCR primers designed to be specific for different JPH3 isoforms, independent confirmation of the presence of two JPH3 mRNA transcripts (the full length and a shorter alternatively spliced version) was provided. In the absence of brain tissue from an HDL2-affected individual, it was investigated whether both JPH3 mRNA transcripts could be detected in lymphocytes. Using RNA isolated from the transformed lymphocytes of two HDL2-affected family members, real-time PCR was attempted. These experiments produced inconclusive results and required further optimisation. Further RT-PCR experiments for JHP3 expression in different tissues (brain and other) obtained from HDL2-affected individuals would be of interest. The present study identified the first Mixed Ancestry family with HDL2. This family will now be able to request genetic counselling and pre-symptomatic testing for all at-risk family members. Aspects of this study provided independent confirmation of characteristics of the mutated gene. More research on HDL2 will be crucial in understanding the pathogenesis of this disease.
