Ever wonder why your boyfriend can't remember the day you met, or your husband from time to time forgets your birthday? Scientists say it may be because of the male brain.
Now men may have an excuse for forgetting things. A new study out from the Mayo Clinic finds that mild cognitive impairment, or MCI, may affect more men than women.
MCI is a memory condition that happens even before the normal aging process that leads to dementia.
The study found that MCI was 1.5 times higher in guys than gals.
Researchers studied 250,000 people between the ages of 70 to 89 in a rural county in Minnesota. All were interviewed about their memory and their medical history and then tested on their thinking skills.
Scientists found that nearly 14 percent of participants had mild cognitive impairment, about 10 percent had dementia and 76 percent of those tested had normal memory.
A total of 19 percent of men had mild cognitive impairment, compared to 14 percent of women.
Researchers suggest that these results show gender may play a role in this disease, but aren't sure exactly how.
They also noted that men may experience cognitive decline earlier in life, and lose their memory gradually, whereas women may transition from normal memory directly to dementia at a later age but more quickly.
