WASHINGTON (Reuters) – According to a US study, the risk of developing Alzheimer's disease is about 50% higher if people with a second-degree relative have the disease.
Although it is known that the presence of a parent with dementia increases the risk of developing dementia, new research shows that even cousins, uncles, uncles or grandparents with this condition may be considered as a harbinger of the infection. The researchers found this link by studying more than 270,000 people in Utah's population database, which contains information on the country's primitive population and their descendants since 1800.
The researchers found that anyone with two children with the disease was 25% more likely to suffer from Alzheimer's disease, while two or more cousins might have a 17% higher risk of developing Alzheimer's disease.
According to the results of the study, second-class family members with Alzheimer's disease can also be considered as a warning factor for the person's illness. More than half of people with Alzheimer's disease have a specific gene that is more than three times more likely to be infected, and it is also thought that other genes transmitted by families are at the origin of the disease.
"Family history is an important indicator of the risk of Alzheimer's disease," said Dr. Lisa Canon Albright, head of study at the University of Utah. "But most research focuses on dementia among immediate family members, so our study looked at larger family photos.
