>>>I believe I replied directly to this query (i.e. not posted) a while
back, describing my experiences with a patient. I'll reiterate one or
(1) yes, one must always act around and talk to the patient as one
would with anyone else, with of course tactful recognition of the
problem in responding.
(2) there are many atypical variations--my patient did NOT have much
eye control; paradoxically, he could sometimes make large movements
(e.g. catch something thrown at him!)
(3) degree of attention and/or motor control may vary widely from time
to time (perhaps particularly in atypical cases?) Be alert for periods
of responsiveness and nonresponsiveness.
