A brand new study published in the American journal with the maximum impact factor in world-wide, Molecular Psychiatry, shows that consumers of cannabis are more prone to experiencing false memories.
The study was conducted by researchers from the Human Neuropsychopharmacology group in the Biomedical Research Institute of Hospital de Sant Pau and from Universitat post traumatic stress Autonoma de Barcelona, in collaboration with the Brain Cognition and Plasticity group of the Bellvitge Institute for Biomedical Research (IDIBELL - University of Barcelona). Among the known consequences of have this drug is the recollection issues it can cause. Continual consumers show more issues than the general population in memories that are recovering and retaining new information. The brand new study also reveals that the chronic utilization of cannabis causes distortions in memory, making it easier for fictitious or fictional recollections to seem.
On occasions, the brain can recall things which never happened. Our memory is made up of malleable procedure which is created increasingly and consequently is subject to distortions or false memories. These recollection "mistakes" are seen more frequently in several neurological and psychiatric disorders, but may also be detected in the healthy people, and become more common as we age. Some of the very common false memories we have are from our youth which we believe to recall since the people around us have described them to us over and over again of situations. Maintaining an acceptable control over the "veracity" of our memories is a complicated cognitive task which allows us to have our own awareness of reality as well as shapes our behaviour, predicated on previous encounters.
In the study published in the journal Molecular Psychiatry, researchers from Sant Pau and Bellvitge compared a group of chronic consumers of cannabis to a healthy control group while they worked on learning a succession of words. After a couple of minutes they were once again shown the original words, together with new words which were either semantically related or unrelated. All participants were requested to identify the words belonging to the first list. Cannabis consumers believed to have seen the semantically associated new words to a degree that was higher than participants in the control group. Researchers discovered that cannabis consumers showed a lower activation in areas of the brain related to memory processes and to the overall control of cognitive resources, by using magnetic resonance imaging.
The study found recollection deficiencies regardless of the fact that participants had ceased consuming cannabis one month before participating in the analysis. Although they had not consumed the drug in a month, the more the patient had used cannabis throughout their life, the lower the degree of activity in the hippocampus, vital to storing memories.
The outcomes show that cannabis consumers are somewhat more exposed to suffering memory distortions, even weeks after not consuming the drug. This indicates that cannabis has a protracted effect on the brain mechanisms which allow us to differentiate between imagined and actual events. These recollection blunders can cause problems due to the effects the testimonies of their casualties as well as witnesses can have, for example, in legal cases. However, from a clinical perspective, the results point to the fact that a continual use of cannabis could worsen difficulties with age-related memory loss.
