In a surprising outcome of one latest study, scientists say that a low dosage consumption of marijuana for a substantial period may help treat dementia, a disease in humans which causes memory loss.

Memory loss is a natural occurrence in humans as the body ages. With ageing, the cannabinoids which are formed regularly in the brain suffer a downfall and when it happens, the brain starts ageing speedily. This study when conducted on mice, showed that when there is an absence of receptors in their body due to age, the THC i.e. tetrahydrocannabinol is not well received. This THC is the cause of the psychological imbalance that marijuana causes.

In this study conducted at the University of Bonn, Germany, the scientists injected some proportion of THC in the mice of different age ages. The test was conducted on three mice aged 2, 12 and 18 months for a span of four weeks. The results were surprising since the memory aspect in the oldest mice was similar to the one in the youngest. There was no loss of performance seen in the mice of different age groups.

There have been researches on humans of tender age and the consumption of cannabis by them has observed to be harmful but this is first of its kind of test where old brains memory improvisation has been attempted. This research in Nature Medicine journal proves that low but regular intake of cannabis can help reverse the memory loss and extend ageing of the brain and boosted the functioning of the brain when tested on mice similar seen in the young, adolescent minds.

Now, to check whether this works on human in the same manner or not, the researchers want a clinical investigation to know if the cognitive skills can be improved in humans through marijuana or not.
