BIRMINGHAM, AL (WBRC)- "As a parent you know something is wrong," Julian Maha said.
Maha says at around 16 months, it was clear something was wrong with his first-born child.
"He had lack of eye contact was the first big thing. The second thing was whenever you call his name he would pretend he would not hear you. It was almost like he was deaf," said Maha.
There were several tests performed on him, but it wasn't until age four that his son was diagnosed with autism.
"As a parent when you have his whole future mapped out, especially your first child, first-born, you have to take a step back and re-evaluate," Maha said.
Four years old is the average age a child is diagnosed, but that could change. In a new study by Emory University, researchers used specialized eye-tracking technology to measure how babies look at and respond to things with their eyes.
