I think it would be worthwhile to look at the brain of older people who have used marijuana chronically and compare it with the brain of age-matched people who never used it. This simple comparison could throw added light on whether cannabis could help people with Alzheimer disease.
The research is very interesting and important. In Los Angeles, California, use of medical cannabis is encountered working in the field with adolescents or young adults. There is indeed controversy since hidden side effects include perceptual and family disorders. Those also need consideration at the psychosocial level.
At the neuronal level, cannabinoid research also needs to rule out an effect of cannabinoids on reducing prion fibrils (see Colin et al., 1999) or neurogenesis (La Spada, 2005). Neuroendocrine effects, prolactin release, gonadal atrophy, and tumor genesis need attention when studying cannabinoids.

Cannabinoid agonist is shown to have a thermal hyperalgesia effect in inflammatory pain involving the sensory pathways and activation of the calcineurin (Nathaniel et al., 2006). The role of sensory inhibition, anhedonia, and known effects of calcineurin in psychosis also need consideration.
