Neurotherapy’s effects on strokes are similar to those with traumatic brain injury (TBI). The greatest difference is that with strokes the damage can be deep within the brain. Subsequently, issues stemming from the stroke may not have a related EEG signal on their scalp. Whereas, with head injuries the outer part of the brain closest to their skull is always affected. This does not mean that someone who suffered from a stroke will not improve their performance with neurotherapy – it just means that improvements can be inconsistent from person to person and issue to issue. This also applies to TBI when the brain stem is damaged, which is rare.
