In what the university calls the largest study of its kind, researchers used brain imaging technology to explore the effects of recent and lifetime cannabis use on brain function among more than ...
A large study from the University of Colorado found heavy cannabis use is linked to reduced brain activity. Lead researcher Joshua Gowin and neurosurgeon Paul Saphier discuss the impact on health.
Cannabis is the most widely used illicit drug in the Western world. [3] In the United States, 10-20% of those who begin the use of cannabis daily will later become dependent. [4] [5] Cannabis use can lead to addiction, which is defined as "when the person cannot stop using the drug even though it interferes with many aspects of his or her life."
New research shows that heavy lifetime use of cannabis — more than 1,000 times — is associated with reduced activity in areas of the brain involved in working memory. The study adds to ...
The brain is more vulnerable to oxidative stress than other organs, due to its low oxidative capacity. Because neurons are characterized as postmitotic cells, meaning that they live with accumulated damage over the years, accumulation of ROS is fatal. Thus, increased levels of ROS age neurons, which leads to accelerated neurodegenerative ...
It is known that air pollution, particularly small particle pollution, can affect the heart and the circulatory system, including circulation to the brain. These effects are linked to vascular dementia (a form of dementia), which is caused by damage to the blood vessels in the brain. [65]
Water intoxication, also known as water poisoning, hyperhydration, overhydration, or water toxemia, is a potentially fatal disturbance in brain functions that can result when the normal balance of electrolytes in the body is pushed outside safe limits by excessive water intake.
Alcohol is still more widely used, but 2022 was the first time this intensive level of marijuana use overtook daily and near-daily drinking, said the study’s author, Jonathan Caulkins, a ...
