ABSTRACT There is a common experience of forgetfulness and mental fogginess among pregnant, often referred to as "pregnancy brain." However, the question of whether this phenomenon is genuine remains unclear. Pregnancy is a unique physiological process that involves significant hormonal and physiological changes in a woman's body. While the physical transformations during pregnancy are well-documented, there has been growing interest in investigating potential cognitive changes that may occur during this period. This review aims to explore the existing literature on pregnancy-related cognitive impairment and provide an overview of the current understanding in this field.
