Dr. Ashford's papers on MemTrax and Alzheimer's disease, including 2 papers that show that MemTrax is a superior test to the Montreal Cognitive Assessment (MOCA), which substantially outperforms the Mini-Mental State Exam (MMSE), which does not outperform several tests from the same era (see Ashford, 2008).

- A-Screen is a test that is recommended for primary care practitioners to screen patients over the age of 60 years for possible cognitive impairment.  - The standard MMSE, as a group of items to be arithmetically summed (removed pending resolution of copyright issues), is  not  recommended by this site.  Note that there have been recent attempts to pull this test from the public domain by the new owners of the copyright, who have also obtained a trademark for this widely used term. As a clear public domain alternative, the Stanford / VA Alzheimer Center has developed the Brief Cognitive Exam (removed pending resolution of copyright issues). A better approach to dementia severity measurement is to complete the "Item Response Analysis" version of the MMSE, provided here, and calculate an estimate of the relative number of years into Alzheimer's disease, MMSEi.  The extended version, MMSEe, provides a broader assessment.

ALZHEIMER  HYPOTHESIS (Dr. Ashford's Neuroplasticity Hypothesis)

Dr. Ashford's comment on the NIH State-of-the-Science Conference, April 26-28, 2010 (This conference downplayed important developments in research on risk factors, particularly genetics, and prevention of Alzheimer's disease, while recommending RCTs - randomized controlled trials - before we even know what to test.)
