Pregnancy brings about remarkable changes in your body. One such change is related to your memory, resulting in a condition called pregnancy brain. No, pregnancy does not change your brain structure, but it can make remembering things difficult.

Here, MomJunction helps you understand the possible reasons for pregnancy brain and how to deal with the situation.

What Is Pregnancy Brain?

Pregnancy brain, also referred to as ‘momnesia’, is just forgetfulness that many women experience during, and for a short period after, pregnancy. Around 50 to 80% of women are said to be forgetful during pregnancy (1).

Some studies suggest that a woman’s cognitive as well as executive functioning are affected to some extent during pregnancy (2). Problems with memory may begin in the first trimester and continue until the third trimester when the forgetfulness could peak.

Researchers think that pregnancy brain helps the expecting mother to cope up with the stress after childbirth and connect with the baby emotionally (3). However, there is a lack of substantial evidence to validate such claims.

The following section details the possible reasons for pregnancy brain.

What Causes Pregnancy Brain?

Pregnancy brain can be due to (1):

  • Hormonal changes during pregnancy can impact the areas of the brain that are associated with memory.
  • Plasma level changes of neurotransmitters such as dopamine and serotonin.
  • Anxiety and stress experienced during and post pregnancy can affect the brain functions related to recognition and memory.
  • Sleep deprivation could also affect how you recollect things.

How Does Pregnancy Brain Affect You?

Here is how pregnancy could affect the brain:

  • Impacts memory: Studies have suggested that pregnant women tend to have a poor memory when compared to non-pregnant women (4). Memory functioning was found to be worse during the third trimester and the early postpartum period. However, the condition is temporary, and you may get back on track once you get adjusted to the new life.
  • Recognition memory: Though the tests showed that pregnant women had difficulty recollecting and retrieving information, their recognition memory was not as affected (4).
  • Changes in the gray matter: Some studies have found that the shrinkage of gray matter in some areas of the brain can slow down the responding and processing functions (5). However, some researchers suggest that this helps the women to be more tuned and focused on what their babies need.

Managing your days with a pregnancy brain is not easy. Next, we have a few tips on dealing with pregnancy brain.
