My teenage boy has recently been diagnosed with Asperger's Syndrome, which makes sense to him as he has always found peer groups difficult. Up until now he has done very well at school academically, but can't cope with the workload of A levels and is slipping behind badly. He is so rude and stubborn at home we can't address any of his organisational difficulties; he insists on doing athletics which is taking up all his spare time, and won't go to bed on time so is pretty exhausted. He doesn't want to discuss any of this stuff. Should we just let him flunk his work or try and address it?
