Did Neandertals die off because of cannibalism and transmissible spongiform encephalopathies?

So there's this hypotheses that Neandertal extinction was due to cannibalism. This is an alternative but complementary hypothesis to the climate change one. In an upcoming paper in Medical Hypotheses, Simon Underdown investigates this hypotheses by looking at Transmissible Spongiform Encephalopathies (TSEs).
