For decades misconceptions have persisted about cannabis (marijuana) due to poor studies and the propaganda of prohibition. Good science is eliminating many of those misconceptions. This study set out to determine the association of alcohol use with gray matter volume and white matter integrity; and of cannabis use and gray matter volume and white matter […]
According to this Science Daily piece, excitotoxicity can be involved in neurological diseases such as Multiple sclerosis, Alzheimer’s disease, Amyotrophic lateral sclerosis (ALS), Fibromyalgia, Parkinson’s disease, and Huntington’s disease. Excitotoxicity is a term used to explain the chemical events that cause nerve cell damage and death. Sometimes the source of the chemical problem is in […]
Studying older adults offers an opportunity to explore associations among cannabis use, brain structure, and cognitive function and to observe any potential harm or benefit from the use of cannabis (marijuana). This pilot study used structural MRI to compare brain volume and function between users and non-users of marijuana. On average, the users had 23.5 […]
Magnetic Resonance Imaging (MRI) was used to search for any effects on the hippocampus, which is a region of the brain especially involved in memory as well as motion. A group of 22 older, long-term cannabis (marijuana) users with an average lifetime of 20,100 smoking episodes were compared to 26 comparison subjects with no history […]
There are many who still question both the short and long term potential effects of cannabis (marijuana) use on multiple aspects of brain function, and those questions may take decades to fully answer. However, this study attempted to determine the non-acute effects of marijuana use on associative memory investigated with functional magnetic resonance imaging (fMRI). […]
During the several recent decades of cannabis (marijuana) prohibition, usage of the plant was often associated with negative brain effects in the propaganda pushed forth by those who profited from making the plant illegal. “Frying your brain” is one phrase that comes to mind. At the extreme end of the spectrum are those who will […]
Nearly everyone has heard the one about marijuana (cannabis) causing brain cells to die. Based on the number of times that propaganda was circulated around the United States you would think there were many studies of validity which found this to be true. You would be wrong. Quite wrong. In fact, when Ronald Reagan made […]
Neurodegenerative diseases are typically associated with inflammation in the brain. Although unclear as to why, inflammation often damages proteins that get “sticky and twisted”, described as plaque and neurofibrillary tangles. This process in most age-dependent neurodegenerative diseases leads to nerve cell death and there are no current (synthetic) medications which effectively inhibit that cell death […]
There are many findings that suggest the endocannabinoid system could be a target for improving the symptoms and progression of Alzheimer’s disease. Therefore researchers wish to know the effects of THC, CBD or both on the disease. In the research world, animal models are often used before testing on humans. In this study mice were […]
Traumatic brain injury (TBI) events leads to significant numbers of death and disease conditions. It is well documented that marijuana (cannabis) offers neuroprotective benefits to the brain. This study was performed to determine the association of death following traumatic brain injury in relation to testing positive for THC, a major marijuana component. There were 446 […]
