My husband had open heart surgery, then about 6 months later was diagnosed with Alzheimers. He has good memory of past and recent events so I'm not convinced he has it. One doctor suggested Aphasia. He is 81 years old and can think of what he wants to say but just can't get it out. His mother was the same way - exactly. If it is Aphasia could it be hereditary? When he's trying to say something he is almost like a stutterer and he gets so frustrated. He won't go around people because he feels they will think he's crazy. Any answers or ideas?
