Autism:There's Hope on the Horizon

Question: What will be the impact of your\r\n research on autism\r\ntreatment?

\r\n\r\n

Michael Wigler: Yes, well there are two ways\r\n in which our\r\nwork could inform clinical treatment. \r\nIn the area of early diagnosis. \r\nIf there’s a child and it’s developing—it’s giving off \r\ndevelopmental\r\nclues there might be something wrong, if we had a list of the kind of \r\ngenetic\r\nlesions we could screen for, we might be able to determine early on that\r\n this\r\nchild is going to develop a form of autism.  And \r\nif it’s correct—most disorders are correctable to the\r\nextent that they are correctable, are more correctable early than late, \r\nwhen we\r\nknow how to correct or treat, we’ll be able to start that sooner.  So, early diagnosis is going to be\r\nimportant for any disorder.  That’s\r\none way. 

\r\n\r\n

Another way is children with a particular genetic \r\nabnormality,\r\nthat is, those children who share genetic abnormality, may have one \r\nparticular\r\nway of treating them that’s different than children who have a different\r\nabnormality.  We will only learn\r\nabout that once we can separate these children according to their \r\ngenetic\r\nabnormalities.  That’s going to\r\ntake many, many years. 

\r\n\r\n

The third way is that in some cases, we will be \r\nidentifying\r\ngenes, who by their very nature, tell us this is a correctable, \r\ntreatable,\r\nsyndrome.  For example, we find a\r\ngene that’s involved in metabolism. \r\nThis child is perhaps got really a storage disorder of some type,\r\n but\r\naltering the diet in those cases might be able to treat the child.  But unfortunately, we don’t yet know\r\nthe identities of the autism genes. \r\nWe have regions and there’s a huge effort underway. \r\n I would say, in particular by doing\r\nvery exhaustive sequence comparisons of children to their parents, we \r\nwill\r\nidentify the actual culprit genes. \r\nAnd that will take us two to four years.  And\r\n there may be, unfortunately, I’m estimating around 400\r\nsuch genes that each one of which can cause autism.  But\r\n when we have those genes, we see what they do; we can\r\nsee what pathways they are interacting with, some of those will suggest\r\nimmediately treatments that can be tested.  We \r\nwill be able to make animal models and test drugs in\r\nanimals to correct these things. 

\r\n\r\n

So, in general, the way to understand a disorder is\r\n to\r\nunderstand its causes and then address those causes.  In\r\n the case of autism, most people would agree, I think most\r\nscientists would agree the causes are genetic, and we have a pathway to\r\ndiscover the genes.  So it will be\r\neasier to diagnose, classify by diagnosis into behavioral and even drug\r\ntreatments, and discover new drug treatments.

New research on the underlying causes of autism could soon lead to earlier diagnoses and better treatments.

Ideology drives us apart. Neuroscience can bring us back together.

A guide to making difficult conversations possible—and peaceful—in an increasingly polarized nation.

  • How can we reach out to people on the other side of the divide? Get to know the other person as a human being before you get to know them as a set of tribal political beliefs, says Sarah Ruger. Don't launch straight into the difficult topics—connect on a more basic level first.
  • To bond, use icebreakers backed by neuroscience and psychology: Share a meal, watch some comedy, see awe-inspiring art, go on a tough hike together—sharing tribulation helps break down some of the mental barriers we have between us. Then, get down to talking, putting your humanity before your ideology.

  • America's two political tribes have consolidated into 'red' and 'blue' nations, with seemingly irreconcilable differences.
  • Perhaps the best way to stop the infighting is to go for a divorce and give the two nations a country each

Why a federal judge ordered White House to restore Jim Acosta's press badge

A federal judge ruled that the Trump administration likely violated the reporter's Fifth Amendment rights when it stripped his press credentials earlier this month.

WASHINGTON, DC - NOVEMBER 16: CNN chief White House correspondent Jim Acosta (R) returns to the White House with CNN Washington bureau chief Sam Feist after Federal judge Timothy J. Kelly ordered the White House to reinstate his press pass November 16, 2018 in Washington, DC. CNN has filed a lawsuit against the White House after Acosta's press pass was revoked after a dispute involving a news conference last week. (Photo by Alex Wong/Getty Images)
Politics & Current Affairs
  • Acosta will be allowed to return to the White House on Friday.
  • The judge described the ruling as narrow, and didn't rule one way or the other on violations of the First Amendment.
  • The case is still open, and the administration may choose to appeal the ruling.
