Sorensen, Eric. "Prospective Alzheimer's Drug Builds New Brain Cell Connections, Improves Cognitive Function of Rats." ScienceDaily. ScienceDaily, 11 Oct. 2012. Web. 11 Oct. 2012. <http://www.sciencedaily.com/releases/2012/10/121011090653.htm>.
Researchers at Washington State University have successfully synthesized a drug that could possibly help repair some of the damge done to the brain by Alzheimer’s disease. Alzheimer’s is a form of dementia and affects cognitive thinking and brain function. It is severely traumatic for the brain and can often result in the death of the victim. It affects 1 in 85 people worldwide, including 5.1 million people in the US. It is caused by plaque buildup in the brain which affects how cells in the brain communicate with each other. This lack of blood flow not only slows the cells functions but also damages it. This drug is a protein molecule small enough to pass through the blood barrier of the brain. The protein helps to rebuild brain cells damaged by the disease. It had a 90% success rate on the lab rat, hopefully it has a similar effect on humans although it is still far from clinical trials. This drug doesn’t necessarily slow down Alzheimer’s but it does repair the damage done by the disease.
The article is describing how much potential this drug has and the hopeful future it brings to many people suffering from Alzheimer’s. This drug will have a huge effect if it proves successful in clinical trials. It provides a beaming ray of hope in the medical field as somebody learned how to make a small enough molecule to break through what was thought to be the nearly impossible blood barrier of the brain which is meant to keep out foreign chemicals such as drugs. I chose this article because this is a disease that affects millions in our nation, but also around the world. It is one of the most severe diseases in my opinion because this disease takes your mind before it takes your body.
I thought the article was well written although has a few discrepancies. It was loosely written. There wasn’t a lot of cohesiveness between paragraphs in my opinion. The author could’ve countered this by developing bridge sentences between paragraphs in order to set up the next paragraph. Other than that, I’d say that the author did a fine job at explaining a difficult topic in ways that can be understood by people without knowledge of neurofunctions.
