Hello everyone. Bit of a long story, my son is now 22 and was diagnosed with aspergers syndrome aged 9. He was put on 1/2mg of rispiridone once a day at the age of 15 by cahms and at 16 cahms signed him off as he was no longer in school. He saw the mental health people twice at age 18 and 19 then they told me they were signing him off as autism is a mental disability not a mental health issue and when I asked who he should see considering he was on psych meds, I was told he would be reffered by his gp to the right people. 2 gps later and still no joy. Every so often he will go to the gp and say his meds aren't working anymore so can they raise the dose which they do and he's now on 3mg twice a day. For the last 18 months he's been fainting and he's been to outpatients for every xray,scan and trace known to man and all they can come up with is that every so often for no apparent reason his heart goes too fast so he faints. He can be completley out for anything up to 30-40 minutes. Is it possible that it may be a side effect of the rispiridone? Thanks in advance for any advice as I'm totally clueless on this one and even the hospital are baffled
