This all sounds like me; I look normal but dementia is extremely difficult for me as internally I struggle with almost everything. It took me 45 seconds just to look up the word dementia, another 30 seconds to write interally. Simple words when taking is ok; but don’t ask me what I am looking for or need, how to get from point a to b without gps. I had to retire from my best job I work so hard to get, lost my pilot (I had to take 30 plus seconds to figure out how to spell it) license which was my patience! It is and every hour struggle!
