Study Links Pregnancy Forgetfulness to Hypothalamus-Hippocampus Brain Circuit

Scientists identified a brain circuit disruption linked to pregnancy-related forgetfulness, commonly known as momnesia or mommy brain.

Experiments on mice showed that sustained high levels of oestrogen increase hypothalamus neuron activity, which suppresses hippocampus activity and impairs memory.

Researchers found that removing oestrogen receptors from hypothalamic neurons reversed the memory problems induced by elevated oestrogen levels.
