My 15 year old suffers with extreme OCD it's heartbreaking watching him 24/7 ... he's also got ADHD and waiting to be tested for Autism . it's been a long road, they told me at the age of two he had the "Terrible Twos" and so it continued!!.. he also has very slow processing speed .. he has attended Cahms for the last 12 months for CBT and was put on methylphenidate ie Ritalin which has turned him into a monster I have been absolutely terrified of him for last few weeks, he's not the Lil boy he was once when you could restrain him..he's now 6ft and 14 and a half stone!! To cut a long story short they've stopped the methylphenidate and over a week ago decided to start him on respiridone (which was meant to start last Fri. .. prescription still wasn't available at our doctors today, no answer in cahms since last Fri. I will have to drive to cahms tomorrow to see what's going on) they say they will introduce sertraline also but trying one at a time first. problem is the therapy hasnt helped him, he seems to be worse!! he's so confused and angry ...they give him things to try but he's so slow bless him he doesn't remember . I'm at my wits end as to how to help him, he's paranoid and shouts and screams at me constantly! ! he's making me I'll also . .really don't no where to turn next.
