Washington: People who are free of dementia and have high levels of a protein that indicates the presence of inflammation have relatives who are more likely to avoid the disease as well, a new study has suggested.“In very elderly people with good cognition, higher levels of C-reactive protein, which is related to inflammation, are associated with better memory,” Jeremy M. Silverman, study author from Mount Sinai School of Medicine in New York, said.“Our results found that the higher the level of this protein in the study participant, the lower the risk for dementia in their parents and siblings,” he said.For the study, researchers identified 277 male veterans age 75 and older and free of dementia symptoms.They were given a test that measured levels of the protein.Next, the group was interviewed about 1,329 parents and siblings and whether they had dementia.A total of 40 relatives from 37 families had dementia. A secondary, independent group of 51 men age 85 and older with no dementia symptoms were given an interview about 202 relatives for dementia. Nine of the relatives had dementia.
