Although memory performance decreases with age, marijuana can reverse these aging processes in the brain. This is according to a new study published in the journal Nature Medicine.
In the study, old mice were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with marijuana as its active ingredient. This has strong relevancy in the treatment of brain-related disorders such as dementia. The results are now presented in the journal Nature Medicine.
According to scientists at the University of Bonn and The Hebrew University of Jerusalem, mice have a relatively short life expectancy in nature and display pronounced cognitive deficits even at twelve months of age. The researchers administered a small quantity of THC, the active ingredient in the hemp plant (cannabis), to mice aged two, twelve and 18 months over a period of four weeks.
