The twins are 17 years old and have been in fairly good health. The pregnancy was great besides the period of extreme stress when my husband lost his job and I took on an additional job during months 3-6 of gestation. I also suffered from a severe episode of the flu at the time. One twin has been complaining about headaches in the right side of his head, mostly clustered around the frontal portion of his brain. Whenever he experiences these headaches I note that he becomes unglued and his personality changes. After the headaches subsides he enters a state of exhaustion and shows little or no affect for days. His friend has also commented that during school he will suddenly show outbursts of inappropriate emotions. When the class gets scared he never understands why. I noticed an issue because he was found in a broom closet because he was terrified of his locker. Hes been under a lot of stress recently because he was working on a science project where he had to breed mice, but his female mice were not becoming pregnant. Since Ive noticed something wrong with him I feel I want to make sure my other twin Joanie is okay as well. At the age of 17 Joanie has not yet begun to menstruate and does not have any secondary sex characteristics. I noted that Joanie has always been a very athletic child, had very little body fat and has always preferred more male activities. I would like to know a possible diagnosis for my son Richie and daughter Joanie and if it has anything to do with why his science project wont work.
