To analyze the image data of ad in the brain, the high dimension of the image is the most important problem that should be solved. Principal Component Analysis (PCA) and wavelet transformation are the two popular methods to solve this problem. I will do logistic Regression based on pca to consider whether a person has ad as the predicted variable in the first part. And I will use the functional linear model to consider the wavelet coefficients as the predicted variables in the second part. Finally, i will discuss the advantages and disadvantages of these analysis methods. Location: Cupples i, room 215.

Almost 1/3 of elderly people have this disease. Some biological factors are found to be associated with it, such as gender, age and education level. The governments all over the world have paid a large amount of money to solve this problem, but the result is not as good as people expected. Ad cannot work be cured at this time. To find as soon as possible whether a person has ad is the best way to control. My goal in this thesis is to describe some models to help discover the presence of ad in clinical trials. The original data is collected by oasis (Open Access Series of Imaging Studies). We have about 400 subjects writing in this research. Due to some problems about protection, only 235 subjects have provided the entire information. I will consider these 235 subjects in this thesis, and 100 of them have.

The estimates from nonlinear least square models are used as the initial values for the parameters. For the better interpretation and father's visualization of the estimates, i predict the wavelet coefficients from the model and reconstruct the predicted images. After reconstruction, the effects of Clinical Dementia rating and baseline age can be easily observed while gender has a significant effect.

How ad affects brain structure and tissues has aroused a lot of attention. Due to the high dimensionality of Magnetic Resonance Imaging data, it is difficult to conduct data analysis on them. My thesis uses data from Open Access Series of Imaging Studies, a longitudinal collection of 373 mri sessions from 150 subjects aged 60. Instead of processing images summary directly, i use wavelet transformation to change image data into the wavelet domain for more efficient data reduction. A linear mixed effect model is then fitted for every dominating wavelet coefficient that contains the major information of the images. I discover that the association between the clinical covariates and the features of the brain images that are represented by the dominating wavelet coefficients is monotone but nonlinear over the index of the coefficients. To capture such a nonlinear trend and integrate all features in one model, i try to fit a nonlinear mixed effect model.

Variable ranking feature selection method is applied and then Principle components Analysis was used for feather data reduction. At last, logistic regression was applied to the oasis data set with principle components. In the result of the logistic regression, gender, age, education and some principle components significantly affect the cdr, which is a measurement for. Location: Cupples i, room 199.

In Statistics with writers Thesis, abstract: Alzheimer s disease is most common form of dementia. The cause and development of Alzheimer's disease are not completely understood. Studies results show that the disease is associated with plaques and tangles in the brain (Tiraboschi,.,., 2004). Alzheimer's disease is diagnosed among people who are over 65 years old and the incidence rates increases exponentially after 65 years of age (Brookmeyer, 1998). Several studies have homework indicated that structural mri can help study. The typical set of mri data contains full brain scanned images from different individuals, with intensities on the same two-dimensional domain for each slice.

The main purpose of this type of image data is to combine all the information from images to make statistical inferences about the effects on the populations represented in the images (Morris, jeffrey.,. The Open Access Series of Imaging Studies (oasis) project freely distributes magnetic resonance imaging (MRI) data sets of the brain. Shearlets are becoming one of the best frameworks for representing the multidimensional data efficiently. Shearlet decomposition is applied to the mri data set by choosing a configuration. After decompositions, we had a large sparse coefficients matrix. We used different methods for data size reduction in order to perform a meaningful statistical analysis.

The first ever National Plan is responsive to many of the concerns apa raised in its comments. The first ever, national Plan to Address Alzheimers Disease (AD) was released in may. . The plan has been in development since the national Alzheimers Project Act (napa) was signed into law in early 2011. Apa provided detailed written comments on both the initial framework (pdf, 504KB) and the draft plan (pdf, 441KB) with support from the committee on Aging, division 40, and the national Academy of neuropsychology.

The national Plan is responsive to many of the concerns apa raised in its comments: The Plan explicitly mentions psychologists as a member of the workforce involved in the assessment and care counseling for individuals with ad and their caregivers. It also states that the department of health and Human Services will disseminate, evidence-based dementia-specific guidelines including those generated by psychologists. The Plan also included a strengthened statement on the need for clinical trials on pharmacologic and nonpharmacologic ways to prevent Alzheimers disease and manage and treat its symptoms, including a specific objective on continuing clinical trials on the most promising lifestyle interventions. . Thus, it includes a more balanced approach emphasizing behavioral and cognitive research in tandem with research on molecular and cellular mechanisms and genetic epidemiologic research to identify risk and protective factors for Alzheimers Disease.

Where next?: Therapeutic studies of anti-amyloid agents that include amyloid tracers as biomarkers are expected to be useful for drug development and to clarify the word relation between amyloid removal and clinical effects. Once the (18)F tracers become available for diagnostic use, large-scale longitudinal studies will be needed to clarify their prognostic and diagnostic power in relation to age, risk factors, and ad subtypes. Ultimately, these tracers will hopefully clarify the pathophysiological role of amyloid in ad and contribute to development of new treatments. More than five million Americans are living with Alzheimers Disease (ad the most common form of dementia. Ad gradually destroys memory and the ability to learn, reason, make judgments and communicate, and the disease is considered progressive and fatal. Scientists have learned a lot about the disease since it was discovered more than 100 years ago. Today at Yerkes, our researchers want to stop the devastation ad brings. That is why we are focusing on neuroscience, immunology and vaccine research to better understand how ad develops and progresses as well as to advance the treatment and prevention of this progressive brain disorder).

Background: The hypothesis that amyloid deposition is the leading cause of night Alzheimer's disease (AD) is supported by findings in transgenic animal models and forms the basis of clinical trials of anti-amyloid agents. According to this theory, amyloid deposition causes severe damage to neurons many years before onset of dementia via a cascade of several downstream effects. This hypothesis has, however, not yet been directly tested in human beings because of the very limited possibility of diagnosing amyloid deposition in vivo, which until recently required either brain biopsy or pet imaging with an on-site cyclotron and radiochemistry laboratory. Moreover, a clinical diagnosis of ad requires that patients have dementia, at which stage any effective treatment aimed at reducing amyloid deposition will probably be too late. Recent developments: The amyloid imaging tracers flutemetamol, florbetapir, and florbetaben labelled with (18)F have been developed for pet; they can be produced commercially at central cyclotron sites and subsequently delivered to clinical pet scanning facilities. These tracers are currently undergoing formal clinical trials to establish whether they can be used to accurately image fibrillary amyloid and to distinguish patients with ad from normal controls and those with other diseases that cause dementia. They might also be used as biomarkers to predict development of ad before onset of dementia and to assess the effect of anti-amyloid therapy. Negative amyloid scans indicate absence of ad with a high level of accuracy, but healthy elderly volunteers might have positive amyloid scans, so their predictive value in isolation is less clear. Close association of in-vivo amyloid imaging results with post-mortem histopathological findings was shown with florbetapir in a phase 3 study.
