### I see hysterical paralysis all the time (now it's politically incorrect
to use the gender-related term "hysteria", have to say "conversion"). It's
often easy pick up some telltale signs on examination, most fakers are dumb
and they make a lot of mistakes. And then there is the magnet of truth, the
MRI machine that shows the absence of stroke and other lesions. Sometimes
there is a question of whether the patient has a migraine aura, which is a
stroke mimic but with attentive examination it is often possible to tell
aura from faking.
I don't see psychogenic blindness often. There are a couple neat tricks to
tell it apart from organic blindness, like testing for optokinetic
nystagmus and visual threat. With the most persistent fakers you can do
visual evoked potentials on EEG.
