The sign for "stroke" (as in a blood clot in the brain)
has a couple of variations.
Touch your forehead with an index finger and then strike the palm of your left
flat hand with your fist.
STROKE:
Notes:
There is another sign for "stroke" that uses a flat hand (or even an
"S" hand). It starts at the forehead and "slices" downward (as if
cleaving the body into two halves). The idea behind this sign
for stroke is that often when a person has a stroke it causes half
of the body to become "non-functioning."
