Rebecca Riley - a four year old - has died because of medication prescribed for "a bipolar personality"...)o:

Bipolar children - is the US overdiagnosing? - New Scientist

Extract:

"Rebecca Riley seemed a normal, playful young child, if at times a little boisterous. Then, aged 2, she was diagnosed with attention deficit hyperactivity disorder, and at 3 as having a bipolar personality. By the age of 4, Rebecca was dead, killed by an overdose of the drug clonidine, which was being used to treat her condition. She was also taking the anti-convulsant Depakote (valproate) and the anti-psychotic Seroquel (quetiapine fumarate) to stabilise her mood."

I believe it is foolhardy and indefensible to give psychotropic drugs to children, especially to such a young child as this. Children should be protected BY LAW from being prescribed these drugs. Prescription drugs are potentially very harmful, particularly to children. And attention deficit hyperactivity disorder is not a real disease, of course, only a putative disease. - This poor child was given THREE dangerous drugs, apparently all at the same time. - Giving more than one dangerous drug at the same time potentiates the risk...)o:
