Upon doing some research I came across ODD. My niece exhibits many of the symptoms. She isn't however defiant against ALL authority, just my Mom for the most part. Sometimes my stepfather.. but she has this special rapport with him that her defiance against him is more limited, but he may not "deal" with situations in the most effective manner. Interesting how it's that way when my mom has more effective techniques. She simply seems to hate my Mom, and explodes on her calling her horrible names and saying things her Mother- who has lost custody of her, says about my Mom. And she isn't this way ALL of the time. Mostly it occurs when she doesn't get her way, or has something (i.e. cell phone) taken away. I do have another post with tons of family history and background information. I will be happy to repost if anyone needs to. I tried to post a signature but it turns up blank..? I read on a few posts here that ODD is a useless diagnosis. Is this true? My niece is currently on Vyvanse and Intuniv for ADHD I believe. She does have many underlying emotional issues which leads to her behavior.She displays so many of the symptoms. Source- Mayo Clinic: http://www.mayoclinic.com/health/oppositional-defiant-disorder/DS00630/DSECTION=symptoms My mom is seeking a behavioral specialist/counselor/psychologist and I hope one turns up soon. But, will such doctor seek to diagnose something, like ODD, which is as stated by many, a blanket diagnosis? Her current counselor said that my niece moving in with me- 1600 miles away from her current home may be best. She has already been removed from her mother's home due to many issues and my Mom has custody. I don't know that moving her again will do anything other than cause her more harm. Although keeping her where she is means she hangs with the same friends, and possible sneaks around to see her mother, against a no-contact court order. If the new counselor says the same then I guess we need to discuss the matter further.. Otherwise I truly think a behavioral specialist needs to work on behavioral modification. Anyone have experiences with such actually working?
