ECT (electroconvulsive therapy) is a medical treatment for people suffering from mental illnesses such as depression or bipolar. The therapy involves the neural stimulation through electrical shocks. This is done while a patient is under anesthesia, and this is used as a "last resort" treatment because of the many things that could go wrong.
A dangerous symptom that can arise from this treatment is memory loss.
Our memories are basically a sequence of certain neural impulses, such as seeing something, is converted to a neural impulse by the eye, so that it can be interpreted by the brain. Any foreign electrical impulse has the potential to overwrite those memories.
