I recently gave a lecture for Spectrum News in regards to arousal in autism. We have done a good number of studies in this regard and the lecture, although simplified for the general audience, summarizes some of our findings. I think one of the important take home messages is that we have ways to treat this autonomic arousal that are extremely effective (e.g., TMS). I am also hoping that the same treatment may be of use in preventing sudden cardiac death in autism. Sudden cardiac deaths accounts for some 4,000 unexpected fatalities every year within the United States.
The lecture was given in collaboration with my wife, Emily. For some reason Spectrum News has taken a liking for joint presentations among researchers. Emily was asked to speak about connective tissue disease in autism and I about autonomic dysregulation. My part of the lecture starts at about 28:48. https://www.spectrumnews.org/features/multimedia/webinars/webinar-emily-and-manuel-casanova-on-autonomic-dysfunction-in-autism/
Let me know what you think about it.
