I would like to know what is the theory behind the electrical shock to brain to treat patients suffering from delusions?

I am aware that thoughts are mere electrical excitation of neurons, so is the external electricity to brain some form of de-activation of those electrical excitation of neurons that result in delusions or paranoia?

  • $\begingroup$ Can you add your sources that shock therapy is used for delusions? $\endgroup$

  • $\begingroup$ I missed the ping; my apologies - the two papers deal primarily with depression and atypical psychosis. In other words, I think that delusions are not the primary target of the ECT, but are rather the symptoms of the pathology (the underlying disease/etiology) that is being treated by ECT. So 'patients suffering from delusions' are in fact patients suffering from depression and psychosis in these papers. In turn, a 'psychosis', though sometimes treated a s a condition by itself, is also associated with psychological pathologies such as schizophrenia... $\endgroup$

  • $\begingroup$ ...so I encourage you to think carefully about the answer you are looking for and refine your question accordingly. The problem with the question now is that the answerer is forced to formulate an umbrella answer taking into account very different pathologies, find a common grounds and answer the question based on that speculative premise. Or alternatively, the answerer is forced to answer two separate questions; one on ECT and psychosis, the other on ECT and depression.... $\endgroup$

  • $\begingroup$ ...Both types of answers are far from ideal, given that depression and psychosis are not even mentioned in the question in the first place. $\endgroup$
