Important Notice: Alzheimer Research Forum does not provide medical advice nor promote any product or service. The contents are for informational purposes only and are not intended to substitute for professional medical advice, diagnosis or treatment. Always seek advice from a qualified physician or health care professional about any medical concern, and do not disregard professional medical advice because of anything you may read on this web site. The views of individuals quoted on this site are not necessarily those of the Alzheimer Research Forum.
We list here a collection of special seminars, on-line journal club discussions,
recorded talks and other presentations on the Forum web site that describe a
variety of scientific hypotheses about the pathogenesis of Alzheimer's disease.
Over time, we intend to represent a more comprehensive range of theories. We
hope that readers will be stimulated to think more broadly about this many-faceted
disorder and to consider how this diversity of ideas and data may be integrated
into a more complete picture of the disease.
We have also created the Hypothesis Factory that
is devoted to the presentation and exchange of ideas regarding novel hypotheses,
hunches, theories-in-progress, etc. The Hypothesis Factory is a forum where
people with original or unconventional ideas can publicly present and discuss
them.
Submit a hypothesis. We invite your comments and questions.

Arguments Against the Amyloid Cascade Hypothesis
Ipsen Foundation Symposium:
"Connections, Cognition And Alzheimer's Disease"
A major theme in many of the speakers is that cognitive impairment in Alzheimer's disease is referable to loss of specific populations of projection neurons and the breakdown of highly vulnerable neural systems, especially those involved in memory formation. There is general consensus among these speakers that these neuronal alterations occur largely independent of amyloid deposition.
