Hi,
My husband was diagnosed with primary progressive aphasia at 64. He was also diagnosed with posterior cortical atrophy at that time. That was 5 years ago and in that time he has gotten a lot worse. Most of the tome I have no idea what he is talking about. I am sometimes able to figure it out...that's a good day! He gets really frustrated with his inability to say what he means.
He also has a lot of visual and cognitive issues. I have to help him with pretty much everything. It is a very demanding, stressful, and scary illness.
Stay strong and take care of you!
