Genetic risk factor APOE4 is greatly increased if neuroinflammation is present. Infrared light therapy is a quick, safe, low-cost and easy way to decrease brain inflammation while also stopping the production of beta amyloid plaque. Call 610-940-0488 to discuss treatment options and clinical trials.
One of Quietmind Foundation's scientific advisors Dr. Richard Satave MD delivered a very important talk to the Anti Aging Medicine Association last year and I think it deserves wider exposure. Our work is being recognized more and more as the next wave in medical science innovation and Dr. Satava is a leading proponent and thought leader in that effort.

Marijuana use may pose a greater risk to the developing brains of teenagers than alcohol consumption, according to a new study this week. The analysis, published Wed in the Am J of Psychiatry, found that cannabis had greater short & long-term consequences than alcohol on 4 key components of teens' memory, finding greatly surprised researchers. "We initially suspected alcohol would have a bigger effect," Patricia Conrod, lead author & Prof of Psychiatry at U Montreal told USA TODAY
Researchers looked at 4 cognitive effects: Problem solving, long-term memory, short-term memory manipulation & the ability to stop a habitual behavior when needed. Marijuana had "significant" negative effects on all 4, while the study could not tie alcohol to negative effects, Conrod said. However, alcohol's effects may be greater as teens drink more later in life, Conrod said. Authors examined nearly 4000 students in the Montreal region over 4 years, starting when the average participant was about 13 years old. The students took yearly memory tests & self-reported their alcohol & marijuana use. Those reports were kept confidential "unless such info indicated imminent risk of harm," authors wrote. By the 4th year, 75% of the students had consumed alcohol at least occasionally, while only 30% of subjects had used marijuana. Study observed more daily marijuana users than alcohol users, Conrod said
Study found some of marijuana's negative effects were short-term, while others were lasting. A particularly troubling finding: Young cannabis users may cause long-term damage to a brain function associated with substance abuse. When studying response inhibition —that's an individual's ability to change their actions to help meet a goal —researchers found that teens using marijuana caused long-term damage to their brains. Conrod said that finding may help explain a previously "perplexing" phenomenon: Young cannabis users have been shown to be at a greater risk for addiction later in life.
