I have pursuaded my father to attend a local Alzheimer's support meeting as we are currently trying to get my mum diagnosed as we believe she has been suffering with dementia for nearly four years now! He has come back and told me that someone at the meeting has mentioned semantic psychosis(?) and he thinks it is more likely that mum has this as the first real symptom was that she lost the ability to speak - she can manage one word answers but they're usually the wrong words. I can't find anything about this on the Internet so I'm assuming he's got the name of the condition wrong. Does anyone know of this condition or is losing the ability to speak a "normal" symptom of dementia?
