You conduct a neurological examination and find weakness and loss of sensitivity in the right leg and a very subtle weakness of the right arm.

Which of the following options is correct?

7. A mother visits the family doctor to complain about the aggressive and hyper-energetic behaviour of her thirteen year old son. After a thorough examination the doctor thinks the child might be autistic. However, he sends the mother home without a diagnosis. Why does he do that?
