When does fetal brain development begin?

Patient's question:

I got married last year. Recently, I've been experiencing lower abdominal pain, especially during my period. I'm very worried about it affecting fertility, and I also feel extremely cold and afraid of the cold. Could you please tell me from when does fetal brain development begin?

Doctor's answer:

Around the 20th day after conception, the primordial genes of the embryo's brain begin to form; by the second month of pregnancy, the outlines of the brain's gyri and sulci have become quite distinct; by the third month, the development of brain cells enters its first peak period; during the fourth to fifth month of pregnancy, the fetal brain cells remain in a rapid development peak stage, and occasional memory traces may appear. The occurrence of gynecological diseases not only affects the health of the patient but can also lead to the development of gynecological conditions. Therefore, it is best to have a vaginal discharge test at the gynecology department of the hospital to identify the cause and receive targeted treatment. Additionally, pay close attention to personal hygiene and maintain cleanliness in the perineal area.
