CBD neuroprotective properties have been found by researchers. Studies show that CBD’s ability to act on the endocannabinoid system and other brain signalling systems may provide benefits for those with neurological disorders.
Sativex, an oral spray which is a combination of CBD and THC, has successfully reduced muscle spasticity in sufferers of multiple sclerosis, especially those who were resistant to standard medications (see https://clinicaltrials.gov/ct2/show/NCT00711646).
In other studies, it was found that people with Parkinson’s disease, their quality of life and sleep quality improved following treatment with CBD (https://www.healthline.com/health/parkinsons-disease/cbd-oil-for-parkinsons).
Other studies believe that CBD may in the future be used to prevent cognitive decline in Alzheimer’s disease.
In conclusion, although research is limited at this time, CBD neuroprotective properties have been shown to effectively treat symptoms related to epilepsy and Parkinson’s disease. CBD was also shown to reduce the progression of Alzheimer’s disease in test-tube and animal studies.
