Testing
There are a few different ways to be tested. One method of testing includes genetic testing. Other methods are neuropsychological testing and brain scanning. With the genetic testing, they will be able to see the mutation on the X chromosome. The brain scanning will allow the doctor to look at the brain size, because RTT causes a smaller brain size due to failure of brain maturation. Neuropsychological testing is where a special doctor is brought in to test the limits of the brain. You might have to answer questions, take tests on the computer or with pencil and paper.
