Dr. Leo Galland's List
Drugs With MCI As A Side Effect
Gretchen Heuring | ElderThink | 02.18.11
Dr. Leo Galland is an author and award-winning physician who really believes we need to know what is in the meds we are taking.
He says, "numerous drungs have been shown to produce mild cognitive impairment (MCI). They may create or aggravate Alzheimer's-type symptoms."
Dr. Galland writes that most of the drugs that cause memory loss interfere with a neurotransmitter in the brain. That neurotransmitter (called acetylcholine) plays a critical role in memory and decision-making. Drugs that do this are called "anti-cholinergic." You can read his blog about this on Huffington Post.
Dr. Galland explains how drugs and supplements can interact
Here is Dr. Galland's list. He cautions that we should not make any changes in our medication program without talking to our doctor.
