The paper is part of an investigation by the authors on development of a knowledge based frame work for multimodal medical image in collaboration with the All India Institute of Medical Science, new Delhi. After presenting the key aspects of the Dempster-Shafer Evidence theory we have presented implementation of registration and fusion of T₁and T₂ weighted MR images and CT images of the brain of an Alzheimer's patient for minimising the uncertainty and increasing the reliability for dianostics and therapeutic planning.

The purpose of this study is to understand the importance of exterior environments and to identify the design guidelines for the therapeutic garden for cognitively impaired seniors with Alzheimer's disease and related dementias. The data was collected from 4 Adult Day Care Centers, 2 Nursing Homes, & 1 Assisted living in the U.S.A. from 2001 to 2002 by interview and the floor plan about the outdoor space. Although some may believe that patients with Alzheimer's disease and related disorders are unresponsive to environment, evidence shows that environments especially designed for cognitively impaired seniors can maintain or increase their level of functioning. The use of specially designed exterior environments nay have in reducing incidents of aggressive behavior, and contributing significantly to a wanderer management program. The checklist includes 6 dimensions： safety environment, various sensual stimulations, social interactions, wandering, privacy, and support orientation and reality. The results indicated that the exterior environment have to support wandering behavior, orientation and reality.

beta-Amyloid peptide is considered to be responsible for the formation of senile plagues that accumulate in the brains of patients with Alzheimers disease. There has been a paucity of evidence to support the involvement of reactive oxygen and/or nitrogen species (ROS and/or RNS) in beta-amyloid-induced neuronal cell death. (omitted)

This study is to develop the Alzheimers disease (AD) detection and analysis system using event-related potential (ERP) of AD patients. We recorded ERP in an auditory oddball paradigm in mild AD (n=25), severe AD (n=12), age-matched normal aged controls (n=17), and young controls (n=7). The amplitude and latency of target P300 components were compared among 4 groups. The relationship between P300 measures and neuro psychological test (K-DRS) scores were evaluated by correlations. The latency of P300 was prolonged in AD and the effects were correlated with the severity of dementia. The P300 amplitude was not affected significantly in AD. Theres no difference between normal aged group and young group. These results suggest that the P300 component is specifically affected by Alzheimer type dementia.
