 Hypothesis: Based on the observation that fever is frequently associated with behavioral improvements in children with ASD, it is hypothesized that sulforaphane might lead to functional improvements in ASD because it can up-regulate cell-protective responses, such as heat shock proteins and related mechanisms that are also up-regulated during fever. These mechanisms are central to multiple cellular processes in the central nervous system, including synaptic transmission, and may improve long-range cerebral cortical connectivity, which is depressed in ASD.
