Treatments
There is no special treatment for Kernohan's notch since treatment is completely dependent on the injury causing it. The pressure against the tentorium should be relieved and the notch should go away. However, this does not mean that damage to the motor fibers disappears. Depending on the severity of the injury, there may or may not be persistent damage after pressure relief. Neurological deficits may resolve after surgery, but some degree of deficit, especially motor weakness, generally remains.
Pressure relief to "un-notch" the cerebral peduncle may include the removal of brain tumors and blood clots or the suction of blood from a drilled hole in the skull.
