The Neuroprotective properties, Functions and Roles of Cannabis sativa in selected diseases related to the Nervous System

Background: Cannabis and its extracts are now being explored due to their huge health benefits. Although, the effect it elicits whether in humans or rodents may vary based on the age of the animal/subject and or the time in which the extract is administered. However, several debates exist concerning the various medical applications of these compounds. Nonetheless, their applicability as therapeutics should not be clouded based on their perceived negative biological actions.

Methodology: Articles from reliable databases such as Science Direct, PubMed, Google scholar, Scopus and Ovid were searched. Specific search methods were employed using multiple keywords: ”Medicinal Cannabis; endocannabinoid system; cannabinoids receptors; cannabinoids and cognition; brain disorders; neurodegenerative diseases”. For the inclusion/exclusion criteria, only relevant articles related to medicinal cannabis and its various compounds were considered.

Result and conclusion: The current review highlights the role, effects and involvement of cannabis; cannabinoids and endocannabinoids in preventing selected neurodegenerative diseases and possible amelioration of cognitive impairments. Also, cannabis utilization in many disease conditions such as Alzheimer’s and Parkinson’s disease among others. In conclusion, the usage of cannabis should be further explored as accumulating evidence suggests that it could be effective and somewhat safe especially when recommended dosage is adhered to. Furthermore, an in-depth studies should be conducted in order to unravel the specific mechanism underpinning the involvement of cannabinoids at the cellular level and their therapeutic applications.
