My 9 year old son has suffered from a number of strep throats over the past year and a half. He has been sick 6 times. Like alot of the families that have been sharing their stories about the symptoms their children were experiencing,My son is exhibiting strange,aggressive, OCD,anxiety, worrying ,separation anxiety, irrational fears and thoughts.afraid to leave the house. My husband died,July,2013 from a very rare autoimmune disease that attacked the liver. Primary Sclerosing Colengitus.my question, is my son merely reacting to the loss of his dad, or could this behavior been brought on by strep and it could be PANDAS syndrome. My son acts out mostly at home. He is a straight A student with good behavior. He does show alot of anxiety at school. If a child is suffering from an undiagnosed case of PANDAS syndrome wouldn t it play out everywhere not at home primarily. Do symptoms come and go. Some more episodes more intense than others
