Alzheimer's disease is inherited?

If both parents were sick with Alzheimer's disease increases the risk of their children, scientists say. The experts on 111 families in which both parents were diagnosed with Alzheimer's disease, the most common mental disorders in older people concentrated. In these families, 297 were adult children. Of the 98 men and women who were older than 70 - 42% met Alzheimer's, U.S. researchers reported at the University of Washington. According to scientists, this is more than expected. The risk of this disease on average occurs in about 65 years. Unfortunately, the number of people affected by the disease increase, every 5 years, experts say. Two thirds of the descendants of the participation in the study had not yet reached 70 years. Taking into account all 297 participants, regardless of age, 23% have been diagnosed with Alzheimer's disease. According to the scientists Bird, on the occurrence of the disease relates to the genetic factor, which is not surprising. Scientists have not been able to find the exact cause of such a relationship. At the moment there is no treatment, and the only known ApoE gene, which may be a risk factor for the disease. The researchers suggest that. Several factors that influence the occurrence of the disease, but it is not known in the art
