Eventually had a letter following a telephone conversation with a Children's Psychiatrist.
The letter said I diagnosed ASD - however, she suspected it and I mentioned some sensitivities and observations - incorrect.
The letter said I opted not to have the assessment for Psychiatric aspects to identify factors contributing to my sons symptoms, as I was already aware of those. Incorrect - I was advised that the assessment would be an assessment similar ti what the Psychologist had already done and as there was no commission (no funding for FND alone), therefore "Talking Therapy" that the Psychologist asked my son back in July to do (which he agreed at the time).
But I guess the above wouldn't surprise anyone, but the real sting in the tail:
Suggesting that if talking therapy did not suffice, consider anti-depressants (suggested without seeing or talking to my son).
