has your son been diagnosed with depression...sometimes teens will have violent outbursts. he may need anti depressant alond with his adhd meds. has he witnessed his father doing something that has upset him in the past and now he is resentful of it? maybe you need family counseling to get to the root of why he directs his anger more at his father. has he ever been tested for odd...oppositional defieant disorder. i go to church with a woman who's son has it and it causes him to get angry very easily and then have violent outbursts...like very bad temper tantrums...throwing kicking, etc.
