One month is VERY early in the recovery process.
To some extent, it appears "nonspecific" complaints of fatigue and
impaired concentration, very much like in some cases of mild traumatic
brian injury (post-concussion syndrome) may be common after stroke,
although traditionally not given so much attention as specific deficits
(aphasia, apraxia, unilateral neglect, etc.), and may persist beyond
After right-hemisphere lesions, persisting perceptual problems might
make one cautious about resuming driving, especially inasmuch as
right-hemisphere lesions might also diminish awareness of having such
With a left-hemispher lesion, such a perceptual/attentional deficit is
much less likely.
Given your father's cautious self-appraisal, I'd say let him monitor
his progress in re-achieving rapid visual processing over the next few
months, with cautious (safe terrain) gradual return to driving at a
rate that seems comfortable. Conceivably, the complaint may persist (I
am thinking of Paula Tallal's study of the left-hemisphere's role in
resolving brief temporal intervals; her focus is auditory, but it
involves visual stimuli as well, and a recent report extends this to
somatosensory stimuli). If so, he may yet be able to develop
Are you near a rehab center with neuropsychologists and/or occupational
therapists competent to evaluate the e xtent of the problem and/or to
help him develop compensatory strategies?
