This strategy protected the litters of Group A mothers from memory decline and accumulation of amyloid and tau protein deposits typical of Alzheimer’s.   Pregnant human moms might just want to consume healthy unsaturated fats in avocado, nuts, and olive oil.  Their dietary choices might just gift their kids agile minds throughout life.   Antonio Di Meco, Jaroslav Jelinek, Elisabetta Lauretti, Mary Elizabeth Curtis, Jean-Pierre J.

Vidcast:  https://youtu.be/UbFatjmobmk   Marijuana concentrate, a form that contains 3 times higher levels of the psychoactive agent THC, is flooding high schools.  This form of weed is associated with more addiction, cognitive problems, and psychiatric disease.   A study from Arizona State University looking at 50,000 high school students finds that one in every three used some form of marijuana and some 24% tried the concentrate.  Those teens using the concentrate showed significantly more addiction risk factors including peer substance abuse, drug-using parents, and academic failure.   Marijuana concentrate users are also likely e-cigarette users, and this route delivers ever higher concentrations of the drug to young lungs and brains increasing the chances for psychosis and addiction.  If your children are using cannabis, be certain that they are aware of the currently circulating and freakishly powerful forms of the drug that must be avoided in order to prevent disaster.   Madeline H.
