Cognitive examination for the early diagnosis of alzheimer's disease

摘要

Alzheimer's disease (AD) is common form of senile dementia. There are several causes for the disease. Any disease - modifying treatments which are developed are most likely to be successful if initiated early in the process, and this requires that we develop reliable, validated and economical ways to diagnose Alzheimer's-type pathology. However, despite comprehensive searches, no single test has shown adequate sensitivity and specificity, and it is likely that a combination will be needed. In this case, the use of advanced biomedical engineering technology will definitely helpful for making diagnosis. Profiling of human body parameter using computers can be utilized for the early diagnosis of Alzheimer's disease. There are several imaging techniques used in clinical practice for the diagnosis of Alzheimer's - type pathology. Apart from above, before going into the major clinical tests and imaging modalities, our aim to develop and implement a Cognitive Test tool to examine the patients cognitive function for the early diagnosis of AD. By this mental state examination, a physician can screen the stage of the disease and store the test results for future purposes. The implementation has been done on the different patients having dementia of Alzheimer's type, can be used as a medical aid as it saves time than the conventional method.
