In an animal study, one group demonstrates that Cannabidiol may help with the neuroplasticity in patients with Alzheimer’s disease (1).
LTP in the hippocampus is the long-term potentiation seen that elevates the efficacy of synapses involved in memory. Beta-amyloid peptide is toxic towards this feature. When animals were pretreated with CBD the neurotoxicity was found to be reduced against beta-amyloid peptide. The same study showed that it did not involve the 5-HT1a, CB1 or adenosine receptors (1).
There have been other previous studies showing that cannabidiol could have protective effects against the toxic effects of beta-amyloid peptide which is involved in the neurodegenerative process seen in Alzheimer’s disease.
More clinical randomized control trials are needed. Animal studies do not always translate into human studies.
