Alzheimer's reduces the connection between brain halves. So, for instance, if you put a hairbrush in an Alzheimer's sufferer's hand they may be able to tell you it's called a brush but cannot remember what it does. In the other hand they may be able to tell you that it's for brushing you hair bet can't recall what it's called. 
Also, I used to do shoe- making as a job and these pliers wouldn't have been practical for leather stretching over a last.
