Ironic Alzheimers news

A new simple eye exam can detect the formation of clumps of proteins well before they are detectable inside the brain.

The problem is preventing these clumps from forming. Another report about trying to prevent just that found

"Two drugs approved for use against Alzheimer's, donepezil and tacrine, reduced clumping by only 22 and 7 percent, respectively."

But THC, the ingredient in marijuana which effects the brain, stopped the clumping completely.

The report ends by making it clear that:

...marijuana is not necessarily good for the mind. Prior investigations have shown that years of heavy marijuana use, consisting of four or more joints a week, can impair memory, decision making, and the ability to pay attention to more than one thing at a time.

But, if you think about it, so does Alzheimers!
