Dr. Shar,
There are a bunch of terms that need to be explained b/4 looking into these abnormalities. I'd suggest u read high yield neuro.
Now, as for apraxia, it's explained in high yield neuro, page 129. However, I'll give u my version.
Apraxia=inability to perform motor fnct even though muscles are intact. For instance, u hand the pt a comb and ask him what he does with it and he won't know. However, they get up in the morning and intuitively brush their hair. Same thing, give them a brush and they won't know what to do with it, but they get up in the morning and brush their teeth. This means that when they have to think about these processes, they won't be able to reproduce what they do in normal lives.
One of this subabnormalities is parking apraxia. Parking involeves some sequencing events and the patient can do each of them individually, one by one....just can't do them in sequence, without interruption. So they do all kinds of things with the steering wheel, but when u ask them to park the car, they can't.
Another example is in unilateral neglect construction apraxia. Most likely, this is the example that would show up on USMLE. This is usually due to non-dominant parietal lobe damage (on Right side). Usually these people neglect the left side of the body. For instance, u ask them to draw a clock and they will draw it only on the right side and leave empty the other half on left side. Also, these people usually only half dress b/c the left side doesn't exist for hem. Or the pt. shaves just half of the face  Another scenario is when the pt will keep hitting the same side of the car.
Sa far as transcortical apraxia, hmmmm, I don't think I have ever heard of this. I have heard of Transcortical Aphasia.
Also, I have never heard of aproxia w/out agraphia. Maybe u mean Alexia (inability to read) w/out Agraphia, meaning that the inability to read is not accompanied by inability to write. So please, specify!!!!!
