Based on a fast skimming of results, it seems the only important question in the above research is what is the proper dosage of DCA. Carcinogenic effects in liver only occur above certain level; neurological disorders occured only above 25mg/kg/day.

As the FAQ at the university's web page suggests, the amount of DCA to use is still an open question to the researchers. Presumably they are aware of the (strange?) side effects of too high a dose of DCA in patients mentioned in these articles.
