Autism and ADHD are becoming better understood, but clinicians can still find the two conditions difficult to tell apart. Now, South Australian researchers say they've identified biomarkers that could allow these two conditions to be diagnosed and distinguished from one another using a simple eye test.
Attention-deficit hyperactivity disorder (ADHD) is the more common of the two conditions, affecting some 5-8 percent of children, primarily boys, and often lasting into adulthood. It carries a relatively broad range of symptoms, mainly centered around inattention, hyperactivity, impulsivity, forgetfulness, disorganization, restlessness, ceaseless talking and noise-making. It's treatable in many cases using stimulant medication such as methylphenidate (Ritalin) and dexamphetamine.
