Would ssri benefit 11 years old boy who has sever anxiety, phobia, and ocd. while the most talkative at home, he is not talking in public or school.

Professional help: He seems to need help from mental health professional.

IMHO: I understand that this type of medication has become common practice in such cases but I am not personally comfortable with it. Young patients can respond with seriously bad responses and before going that route, i'd recommend high quality psychotherapy targeted at ocd and phobia/anxiety - cbt has a very good record and no side effects. If needed, drugs can be added. Best!

Anxiety/ Phobia: Hopefully he has been evaluated by a child psychiatrist. Cognitive-behavioral therapy, psychoeducation of parents and child, school intervention, and medications, such as ssris ( 1st line tr); 2nd line-benzodiazepines for short term; 3rd line-- buspirone. If every thing fails antipsychotics may be useful in high levels of agitation. Cbt are the best supported interventions. Early tr improves prog.
