WASHINGTON: Extremely low doses of THC —the psychoactive component of marijuana — protects the brain from long-term cognitive damage in case of injury from hypoxia (lack of oxygen ), seizures, or toxic drugs, a study has claimed.Medical cannabis is often used by sufferers of chronic ailments, including cancer and post-traumatic stress disorder, to combat pain, insomnia , lack of appetite, and other symptoms.Now, professor Yosef Sarne of Tel Aviv Universityfound the drug has neuroprotective qualities as well.Previous studies focused on injecting high doses of THC within a very short time frame — approximately 30 minutes — before or after injury.Sarne’s current research, published in the journals Behavioural Brain Research and Experimental Brain Research, demonstrates that even extremely low doses of THC — around 1,000 to 10,000 times less than that in a conventional marijuana cigarette — administered over a wide window of 1 to 7 days before or 1 to 3 days after injury can jump start biochemical processes which protect brain cells and preserve cognitive function over time.This treatment, especially in light of the long time frame for administration and the low dosage, could be applicable to many casesof brain injury and be safer over time, Sarne said.While performing experiments on the biology of cannabis , researchers found that low doses of the drug had a big impact on cell signalling , preventing cell death and promoting growth factors. The use of THC can prevent long-term cognitive damage that results from brain injury, the researchers concluded after studies.
