Scientists Discover: Having a Second Child Changes the Mother's Brain in Unexpected New Ways
It's already known that pregnancy causes significant changes in a woman's body. However, scientists have discovered that a second pregnancy causes different changes in a mother's brain than the first pregnancy. According to research conducted by the Amsterdam University Medical Center, the changes that occur in a mother's brain with the second child are quite striking.
Here are the details.
The birth of a baby changes not only the body, but also the mother's brain!
Researchers from the Amsterdam University Medical Center compared the changes in the brains of women who became mothers for the first time and those who became mothers for the second time by examining the brain images of 110 women before and after pregnancy. The results of the study showed that the second pregnancy also changed the brain, but these changes were concentrated in different regions than the first pregnancy.
Sure, What Changes in the Brain During the Second Pregnancy?
With the second pregnancy, a different adaptation process begins in the mother's brain compared to the first pregnancy. Scientists observed notable changes especially in attention, environmental perception, and connections between brain networks during this period. Let's examine the research data in more detail:
- Attention System Changes More
During the second pregnancy, more significant changes were observed in the brain networks associated with attention management and responding to signals from the environment.
Scientists think this could be an adaptation process that helps the mother keep track of the needs of multiple children.
- Brain Focuses More on the Outside World
While changes in the first pregnancy are mostly seen in brain networks related to self-perception, social relations, and understanding others' emotions, stronger changes emerged in systems oriented towards the outside world in the second pregnancy.
- Changes Related to the Mother-Baby Bond Occur
The research showed that changes occurring in the brain during pregnancy could be related to the bonding process between mother and child.
However, this connection was more pronounced in the first pregnancy, while different brain systems were more involved in the second pregnancy.
- Brain Reorganizes Itself
Researchers detected changes in the gray matter, white matter connections, and the working order of brain networks during the second pregnancy.
This situation is considered not as a loss, but as a process of the brain adapting to new life conditions and making some functions more efficient.
- Changes Could Be Related to Multitasking Skills
With the second child, mothers usually have to keep track of more needs at the same time. Researchers suggest that changes in attention and sensory processing in the brain could help adapt to this new order.
Research Could Be Important for Maternal Mental Health
The study examined connections between brain changes occurring during pregnancy and symptoms of perinatal depression. Scientists believe that such studies could be used in the future to detect and support mothers' mental health problems earlier.
