Family history is one of the leading risk factors for developing
Alzheimer's, but a new study from the University of Kansas suggests
inheriting it from your father is preferable to getting the disease
Researchers found that subjects whose mothers suffered
from Alzheimer's experienced "about one-and-a-half times more whole
brain shrinkage per year than those who had a father with the disease."
The brains of subjects whose fathers had the disease remained
"essentially the same as those of subjects with no family history."
Los Angeles Times writes that while the exact reasons are unknown
for the increased aggressiveness of Alzheimer's inherited from mom,
researchers suggest it can be attributed to their role in transferring
"mitochondrial DNA, which is inherited only from one's mother and which
may be responsible for faulty glucose metabolism in brain tissue
affected by Alzheimer's."
