'Momnesia' pregnancy forgetfulness linked ‌to brain circuit disruption

It is sometimes called "momnesia," "mommy brain," "pregnancy brain" or "baby brain" — the ‌forgetfulness, mental fogginess and cognitive ‌changes that many women may experience during pregnancy. For instance, ⁠a ​woman ⁠might walk into the kitchen ⁠and forget why she did, or ​perhaps misplace her car keys ⁠in the bathroom. Scientists know it ⁠is ​a real biological phenomenon, and now have found ⁠a possible explanation, identifying a specific ⁠brain ⁠circuit that becomes disrupted under the sustained high ‌levels ‌of estrogen that ​accompany pregnancy.
