Hormone regulation is very important in terms of not just memory, but overall brain functions. Our brain, just like any other organ system, operates on the presumption that hormones are imbalanced.
One of the things that is most detrimental to women who are perimenopausal, who then become menopausal, is this memory decline that generally happens within 12 months, switching from perimenopausal to the postmenopausal period. It's very common to have that kind of memory decline that then generally levels out. That's not typically any type of impairment. It just happens that your brain is readjusting to the level of available hormone in the body. Once it regulates, all memory functions or attention functions seem to regulate as well.
