Study Finds Gene Warning of Alzheimer's before Symptoms Onset

According to a new study by the University of California, Los Angeles (UCLA) researchers, clusterin, or CLU, one of a handful of genes that is known to carry a heightened risk of Alzheimer's, begins to attack human brain a half-century before Alzheimer's symptoms appear.

UCLA professor Paul Thompson and his team found that the C-allele of the CLU gene, or one of two or more forms of the gene, hinders development of myelin, which protects the neuron's axons in the brain. This makes the brain more vulnerable to Alzheimer's later in life. But the da
