Scientists are investigating a gene that slows down Alzheimer's disease in Puerto Rico

the School for Medicine of the Medical Sciences Campus (RCM) of the University of Puerto Rico investigates which gene delays the development of Alzheimer's in members of Puerto Rican families with hereditary predisposition to the disease. He explained the agency Efe the research lead researcher, Ivonne Jiménez, the research, which began in 2002, led to the discovery of 90 families on the island with the genetic mutation that causes early Alzheimer's disease, known as "Beginning of Alzheimer's disease"(EOAD, in English) or early Alzheimer's disease, in Spanish.

Jiménez He explained that about 200 mutations were related to Alzheimer's at an early age, but they noticed that Puerto Rico there were many affected families with the same type of mutation, something that they are still analyzing. A genetic mutation is a defect in a gene that causes a defective protein to be produced, which can lead to an increased risk of developing a disease.

"We study the risk factors that cause this disease, which expresses the mutation," he said. Jiménez, which started the research in 2002 in collaboration with the head of Neurology and geneticist at Columbia University in New York, respectively Richard Mayeux and Joseph H. Lee. According to the researcher, Mayeux had found it New York many cases of Puerto Ricans and Dominicans with Alzheimer's disease.

The studies

however, Mayeux he visited Puerto Ricoand together with Jiménez, they began to evaluate families whose members had Alzheimer's, and discovered that many were older than 80, but also younger, especially under 60 years of age. "We were surprised that many young, productive and hard-working people had the symptoms of Alzheimer's," Jiménez said. "The younger the person, the more aggressive their character and physical condition deteriorate faster."
