<s>[INST] My 8 year old daughter has ADHD and a yeast allergy, skin problems, and some sinus infections. Her stomach hurts many time when eating also. I have noticed these all to be common in children with ADHD but I can not figure out the connection. Any ideas?Thanks Lisha [/INST] Hello,Welcome to HCM,Diagnosing of ADHD is a process that takes several steps and involves gathering a lot of information from multiple sources.There is no single test for ADHDYou, your child, your child's school, and other caregivers should be involved in assessing your child's behavior.We will consider how a child's behavior compares with that of other children the same age. As your child is having non specific signs and symptoms it cannot be related to ADHD.Your doctor can determine whether your child has ADHD or not.Thank you. </s>
