     I MEANT, of course, "SIGNS" of MS!!

    My curiosity about profile remains.  In a high-functioning         
    individual, all abilities may be normal or above normal, but WITHIN
     this range some will be better than others.

    NOW you've got me curious about who tested you and what the battery
    included!

    Probably you don't have the raw scores, but I'd be interested in   
    comparing Trails A and Trails B--not in terms of centiles or       
    whatever, but in terms of actual times recorded (I have seen some  
    interesting correlates of the B/A ratio), but even A vs. B centile 
    scores would be of interest (MIGHT give a clue re "current         
    problems").

      Visual identification problems: = detection? = recognition?      
      which?

      ALSO: are these lifelong or recent problems?  If recent, would   
      suspect MS as basis.  In my experience, MS patients often have   
     "higher order" visual problems--i.e., NOT just optic nerve level, 
      visual acuity-type problems.

      CONCEIVABLY, recent (rather than lifelong) problems could relate 
      to increae in hydrocephaly beyond what your brain had adjusted   
      to.  If so, procedure neurologist on the head injury unit of my  
      hospital uses might be worth trying.  When normopressure         
      hydrocephaly and/or shunt failure is suspected, he sometimes     
      tries a TEMPORARY reduction of pressure, i.e. withdrawal of      
      a small amount of CSF (c. 50cc??? not sure) via spinal tap. If   
      some improvement noted, encourages placing of shunt (or revising 
      old one if one already in place).

      I think higher order visual problems in absence of ocular        
     symptoms could be possible via either problem--i.e., hydrocephaly 
     or MS (each in it own way affecting white matter in deep          
     temporal-occipital areas).

     I have much compassion, having been through a lengthy hospital    
     siege myself in the past year...
