One of the most promising new treatments for Alzheimer's disease may already be in your kitchen. Curcumin, a natural product found in the spice turmeric, has been used by many Asian cultures for centuries, and a new study indicates a close chemical analog of curcumin has properties that may make it useful as a treatment for the brain disease. "Curcumin has demonstrated ability to enter the brain, bind and destroy the beta-amyloid plaques present in Alzheimer's with reduced toxicity," said Wellington Pham, Ph.D., assistant professor of Radiology and Radiological Sciences and Biomedical Engineering at Vanderbilt and senior author of the study, published recently in the Journal of Alzheimer's Disease. Accumulation and aggregation of protein fragments, known as beta-amyloid, drives the irreversible loss of neurons in Alzheimer's disease. Developing small molecules to reduce this accumulation or promote its demolition is crucial, but the ability of these small molecules to cross the blood-brain barrier has been a restricting factor for drug delivery into the brain. Pham and colleagues at Shiga University of Medical Science in Otsu, Japan, developed a new strategy to deliver a molecule similar to curcumin more effectively to the brain. "One of the difficulties in the treatment of Alzheimer's disease is how to deliver drugs across the blood brain barrier," he said. "Our body has designed this barrier to protect the brain from any toxic molecules that can cross into the brain and harm neurons. "But it is also a natural barrier for molecules designed for disease-modifying therapy," Pham said. To work around the problems of giving the drug intravenously, the researchers decided to develop an atomizer to generate a curcumin aerosol. The Japanese researchers developed a molecule similar to curcumin, FMeC1, which was the one actually used in this study. "The advantage of the FMeC1 is that it is a perfluoro compound, which can be tracked by the biodistribution in the brain noninvasively using magnetic resonance imaging. Curcumin is a very simple chemical structure, so it is not expensive to generate the analog," Pham said. "In this way the drug can be breathed in and delivered to the brain," he said, noting that nebulizers are out in the market already, and are relatively inexpensive. "In this paper we also showed that delivery to the cortex and hippocampal areas is more efficient using aerosolized curcumin than intravenous injection in a transgenic mouse model of Alzheimer's disease," Pham said.

This is old stuff. About ten or so years back reseachers found that Alzheimer's was comparitively rare in India and wanted to understand why. Upon investigation they found it was due to curcuminoids in the yellow curry Indians used in Indian food. It's also in the spice turmeric which gives it it's yellow color. It's hard on your rear end. I've been taking curry and turmeric curcuminum for six years. It helps me maintain a nasty enough disposition to deal with other life problems. The bad news is that curcuminoids will not help you if you are born stupid or are comitted to following a stupid culture. If you insist on wading out into the Ganges river with the crocodiles, curcuminoids won't help you. Q: How many bureaucrats does it take to screw in a light bulb? A: Two. One to assure everyone that everything possible is being done while the other screws the bulb into the water faucet. (Compliments of the Linux Fortune program.)
