Brain Scans Show Early Signs of Autism Spectrum Disorder

For children with autism spectrum disorder (ASD), early diagnosis is critical to allow for possible interventions at a time when the brain is most amenable to change. But that’s been tough to implement for a simple reason: the symptoms of ASD, such as communication difficulties, social deficits, and repetitive behaviors, often do not show up until a child turns 2 or even 3 years old.

Now, an NIH-funded research team has news that may pave the way for earlier detection of ASD. The key is to shift the diagnostic focus from how kids act to how their brains grow. In their brain imaging study, the researchers found that, compared to other children, youngsters with ASD showed unusually rapid brain growth from infancy to age 2. In fact, the growth differences were already evident by their first birthdays, well before autistic behaviors typically emerge.

Autism spectrum disorder includes a range of developmental conditions, such as autism and Asperger syndrome, that are characterized by challenges in social skills and communication. Scientists have long known that teens and adults with ASD have unusually large brain volumes. Researchers, including Heather Hazlett and Joseph Piven of the University of North Carolina, Chapel Hill, found more than a decade ago that those differences in brain size emerge by about age 2 [1]. However, no one had ever visually tracked those developmental differences.

In the new study reported in Nature [2], Hazlett, Piven, and their colleagues set out to collect that visual evidence.

The American Academy of Pediatrics, the AMA, and the American Academy of Family Physicians all encourage their members to ask parents about firearms, in the same spirit as they ask about automobile restraints, swimming pools, and other factors that relate to the health of their patients.  If parents report that there are firearms in the home, the pediatricians advise them on gun safety.  Among homes with children and firearms, more than 40% have at least one unlocked firearm.  A trial in 2008 showed encouraging results when pediatricians counseled parents on strategies for safe gun storage and handed out cable locks, reporting a 21.4% increase in families who stored their firearms locked.

In 2011 the State of Florida passed a law (Firearm Owners’ Privacy Act, or FOPA) that forbade doctors from asking patients whether there were firearms in the home.   The law carried some harsh penalties, including a $10,000 fine and loss of medical license.  FOPA was overturned by the Florida Supreme Court on free speech grounds, but was reinstated by a three judge panel of the 11th Circuit.    Florida managed to convince the panel that: 1) this was not impingement of free speech, but merely a regulation of professional activity; 2) the law was necessary to protect the Second Amendment rights of parents.  A number of physicians and organizations appealed, and on February 17, 2017, a full panel of the 11th Circuit once again overturned most of the elements of FOPA.
