being so fucking attracted to someone who’s famous feels so fucking ridiculous like you know you have no chance with them in any way at all like you barely have a chance to fucking meet them
but you still just
are so attracted to them
so, so attracted to them

Autism is characterized by many different symptoms: difficulty interacting with others, repetitive behaviors, and hypersensitivity to sound and other stimuli. MIT neuroscientists have put forth a new hypothesis that accounts for these behaviors and may provide a neurological foundation for many of the disparate features of the disorder.
The researchers suggest that autism may be rooted in an impaired ability to predict events and other people’s actions. From the perspective of the autistic child, the world appears to be a “magical” rather than an orderly place, because events seem to occur randomly and unpredictably. In this view, autism symptoms such as repetitive behavior, and an insistence on a highly structured environment, are coping strategies to help deal with this unpredictable world.
The researchers hope that this unifying theory, if validated, could offer new strategies for treating autism.
“At the moment, the treatments that have been developed are driven by the end symptoms. We’re suggesting that the deeper problem is a predictive impairment problem, so we should directly address that ability,” says Pawan Sinha, an MIT professor of brain and cognitive sciences and the lead author of a paper describing the hypothesis in the Proceedings of the National Academy of Sciences this week.
“I don’t know what techniques would be most effective for improving predictive skills, but it would at least argue for the target of a therapy being predictive skills rather than other manifestations of autism,” he adds.
The paper’s senior author is Richard Held, a professor emeritus in the Department of Brain and Cognitive Sciences. Other authors are research affiliates Margaret Kjelgaard and Sidney Diamond, postdoc Tapan Gandhi, technical associates Kleovoulos Tsourides and Annie Cardinaux, and research scientist Dimitrios Pantazis.
Dealing with an unpredictable world
Sinha and his colleagues first began thinking about prediction skills as a possible underpinning for autism based on reports from parents that their autistic children insist on a very controlled, predictable environment.
“The need for sameness is one of the most uniform characteristics of autism,” Sinha says. “It’s a short step away from that description to think that the need for sameness is another way of saying that the child with autism needs a very predictable setting.”
Most people can routinely estimate the probabilities of certain events, such as other people’s likely behavior, or the trajectory of a ball in flight. The MIT team began to think that autistic children may not have the same computational abilities when it comes to prediction.
This hypothesized deficit could produce several of the most common autism symptoms. For example, repetitive behaviors and insistence on rigid structure have been shown to soothe anxiety produced by unpredictability, even in individuals without autism.
“These may be proactive attempts on the part of the person to try to impose some structure on an environment that otherwise seems chaotic,” Sinha says.
Impaired prediction skills would also help to explain why autistic children are often hypersensitive to sensory stimuli. Most people are able to become used to ongoing sensory stimuli such as background noises, because they can predict that the noise or other stimulus will probably continue, but autistic children have much more trouble habituating.
“If we were unable to habituate to stimuli, then the world would become overwhelming very quickly. It’s like you can’t escape this cacophony that’s falling on your ears or that you’re observing,” Sinha says.
Autistic children also often have a reduced ability to understand another person’s thoughts, feelings, and motivations — a skill known as “theory of mind.” The MIT team believes this could result from an inability to predict another person’s behavior based on past interactions. People with autism have difficulty using this type of context, and tend to interpret behavior based only on what is happening in that very moment.
Leonard Rappaport, chief of the division of developmental medicine at Boston Children’s Hospital, says he believes the new theory is “a uniting concept that could lead us to new approaches to understanding the etiology and perhaps lead to completely new treatment paradigms for this complex disorder.”
“This is not the first theory to explain the complex of symptoms we see every day in our clinical programs, but it seems to explain more of what we see than other theories that explain individual symptoms,” says Rappaport, who was not involved in the research.
Timing is everything
The researchers believe that different children may show different symptoms of autism based on the timing of the predictive impairment.
“In the millisecond range, you would expect to have more of an impairment in language,” Sinha says. “In the tens of milliseconds range, it might be more of a motor impairment, and in the range of seconds, you would expect to see more of a social and planning impairment.”
The hypothesis also predicts that some cognitive skills — those based more on rules than on prediction — should remain unharmed, or even be enhanced, in autistic individuals. This includes tasks such as math, drawing, and music, which are often strengths for autistic children.
A few previous studies have tried to pinpoint which parts of the brain are involved in making predictions. So far, the strongest candidates are the basal ganglia, the nucleus accumbens, and the cerebellum — structures that are often structurally abnormal in autistic patients. “It’s a very tentative connection at the moment, but I think this is a fruitful line of inquiry for the future,” Sinha says.
Sinha’s team has already begun testing some elements of the prediction-deficit hypothesis. Initial results of one study suggest that autistic children do have an impairment in habituation to sensory stimuli; in another set of experiments, the researchers are testing autistic children’s ability to track moving objects, such as a ball. “The hypothesis is guiding us toward very concrete studies,” Sinha says. “We hope to enlist the participation of families and children touched by autism to help put the theory through its paces.”

People with blood type AB may be more likely to develop memory loss in later years than people with other blood types, according to a study published in the September 10, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.
AB is the least common blood type, found in about 4 percent of the U.S. population. The study found that people with AB blood were 82 percent more likely to develop the thinking and memory problems that can lead to dementia than people with other blood types. Previous studies have shown that people with type O blood have a lower risk of heart disease and stroke, factors that can increase the risk of memory loss and dementia.
The study was part of a larger study (the REasons for Geographic And Racial Differences in Stroke, or REGARDS Study) of more than 30,000 people followed for an average of 3.4 years. In those who had no memory or thinking problems at the beginning, the study identified 495 participants who developed thinking and memory problems, or cognitive impairment, during the study. They were compared to 587 people with no cognitive problems.
People with AB blood type made up 6 percent of the group who developed cognitive impairment, which is higher than the 4 percent found in the population.
"Our study looks at blood type and risk of cognitive impairment, but several studies have shown that factors such as high blood pressure, high cholesterol and diabetes increase the risk of cognitive impairment and dementia," said study author Mary Cushman, MD, MSc, of the University of Vermont College of Medicine in Burlington. "Blood type is also related to other vascular conditions like stroke, so the findings highlight the connections between vascular issues and brain health. More research is needed to confirm these results."
Researchers also looked at blood levels of factor VIII, a protein that helps blood to clot. High levels of factor VIII are related to higher risk of cognitive impairment and dementia. People in this study with higher levels of factor VIII were 24 percent more likely to develop thinking and memory problems than people with lower levels of the protein. People with AB blood had a higher average level of factor VIII than people with other blood types.
