Experts have believed that autism affects four times as many boys as girls, but the ratio may not actually be quite that high. Doctors are learning that autism shows up differently in girls’ behavior as a result of brain differences. This leaves many girls with autism undiagnosed. Experts discuss how it appears in girls and the consequences of those differences.

Guests:

  • Dr. Thomas Frazier, Chief Science Officer, Autism Speaks
  • Dr. Rachel Loftin, Adjunct Assistant Professor of Psychiatry, Northwestern University
  • Dr. Kevin Pelphrey, Jefferson Scholars Foundation, Professor of Neurology, University of Virginia

19-02 Segment 2: Invisible Girls: Victims of Incest

rhj 19-02b wordpress

Experts say incest is the most common of all sexual abuse, but the least discussed openly. This can leave victims isolated and less able to reveal abuse, which can have further psychological ramifications later on. A noted expert on sexual abuse discusses how incest makes girls feel particularly responsible and unable to come forward, and a non-profit organization that seeks to help them.

Guest:

  • Dr. Patti Feuereisen, clinical psychologist and author, Invisible Girls: Speaking the Truth About Sexual Abuse

Medical Notes this week…

It’s well known that the number of people with Alzheimer’s disease and other dementias is rising… but the speed of the increase is stunning researchers. A study in the journal Lancet Neurology finds that the number of people with dementia around the world has more than doubled since 1990. Researchers estimate that within about 30 years… more than 100 million people will be affected with dementia.

Air pollution is bad for your health… but researchers haven’t been able to quantify just how bad until now. A Danish study in the journal Environment International used advanced models to simulate the effects of pollution on large populations. It shows that cutting city pollution to the level found in the country could increase the lifespan of the average urban dweller by one full year.

And finally… it doesn’t take long to believe your own lies. And the older you are, the less time it takes. A study in the journal Brain and Cognition used EEG’s to monitor brain activity of people purposely telling lies… then telling the truth to the same questions 45 minutes later. Researchers found that people over 60 are much more likely than young people to accept as the truth a lie they had told less than an hour earlier. Apparently, scientists say, telling a lie scrambles the memory so people ultimately accept it as what really happened.
