Robert MacNeil has reported a six-part series on the disorder for PBSNewsHour, and the first segment features his 6-year-old grandson, Nick.
The series airs starting Monday.
In the first segment, MacNeil explores his family's sacrifices raising an autistic child. He reveals the pain experienced by his daughter, 10-year-old granddaughter and even himself.
The 80-year-old MacNeil was retired and hadn't planned to work in front of the camera again. But at the urging of his daughter, Alison, he decided it was imperative to cover the disorder.
Alison says she hopes her father's return can show people how important the topic is and lead to more independent research of autism.
