"I have LBD. What products would be best for this?"
The wiki-pedia entry for Lewy body dementia sounds frightening. I have not had the opportunity to treat a patient with this disease, or notice its features in person. It sounds like rapidly progressive dementia along with hallucinations and poor executive functioning. I would try CBD rich cannabis, that also contains THC; inhaled as well as sublingual tincture. It seems that our brains’ "rust" and we need to prevent oxidation. CBD and other cannabinoids play a roll in protecting our neurons. The scientific evidence looks for very promising, but the stigma and criminal penalties remain.
