When Can Pregnancy Brain Start?

Published in Pregnancy and Cognition 1 min read

Pregnancy brain, characterized by forgetfulness and mental fogginess, can start as early as the first trimester.

Hormonal fluctuations are the culprit during this early stage, leading to feelings of frustration and the onset of symptoms commonly associated with pregnancy brain. According to available information, women often report experiencing these cognitive changes very early in their pregnancies.

Here's a breakdown of key factors:

  • First Trimester Onset: Many women report experiencing symptoms of pregnancy brain, such as forgetfulness, as early as their first trimester.
  • Hormonal Changes: The significant hormonal shifts occurring during pregnancy are considered a primary driver of these cognitive changes.
  • Associated Symptoms: Besides forgetfulness, frustration is another symptom often linked to pregnancy brain.

Therefore, while experiences vary, it's not uncommon for pregnancy brain to begin in the first trimester due to the rapid hormonal changes happening in a pregnant woman's body.
