A new study, which is getting a lot of attention, is showing that children with autism may have an oversupply of synapses – which are the connections that allow neurons to send a receive signals –in their brains. With this excess amount of synapses, different brain areas can be affected and overloaded with stimuli. And having such an overload could account for symptoms like extreme sensitivity to noise or social challenges.
This information could help researchers and doctors identify a key cause of autism symptoms – which is good news for a potential treatment. But this would be long down the road – researchers were able to create a similar overloading of synapses among mice and used a drug called rapamycin, which worked well to improve, if not eliminate symptoms, however this drug comes with heavy side effects. But this is an exciting discovery and one that will hopefully be further explored.
