Alzheimer’s: all in the genes?
An international study has shown those who are ‘free’ from dementia and have high levels of protein in their systems are likely to have relatives who are also able to avoid the disease. Researchers at Mount Sinai School of Medicine in New York claimed protein rates were linked to whether a person would have dementia later in life.
An international study has shown those who are ‘free’ from dementia and have high levels of protein in their systems are likely to have relatives who are also able to avoid the disease.
Researchers at Mount Sinai School of Medicine in New York claimed protein rates were linked to whether a person would have dementia later in life.
The team conducted a series of test measuring levels of the substance within a person focusing on a group of male veterans aged 75 years and over with no forms of dementia.
Following the tests, participants were interviewed regarding the status of their family to determine whether Alzheimer’s was present in their relatives.
Of the 1,329 parents and siblings, only 40 individuals within the 37 families were found to be, or had been, living with Alzheimer’s.
Researchers noted the results showed those who had higher levels of protein within their system were 30% less likely to come into contact with any form of dementia.
Lead author of the study, Jeremy Silverman, said protein was related to worse cognition in younger elderly people.
“For very old people who remain cognitively healthy, those with a high protein level may be more resistant to dementia,” he added.
According to Mr Silverman, the study showed this protection may be passed on to immediate relatives.
