Hello Doc My mother had undergone craniotomy following TBI after 2 months of craniotomy she has started speaking. On the 2nd to 5th day she said sentences which we spoke last ...then recently she is forming sentences in a unrelated way, whatever word comes to her mind she speaks mixing all those but she is able to say all the weeks, Counting numbers,saying time etc . So which stage of development is this,is it for memory or speech?
