These  cases  will  be  again  considered  in  the  chapter  on  Epilepsy.  The  con-
vulsions are  almost  always  one-sided,  affecting  only  the  paralyzed  limbs,
and  they  often  begin  locally,  in  some  part  of  this  side,  especially  in  the
hand.  It  is,  however,  a  significant  fact,  indicating  how  profound  is  the
influence  of  the  repeated  discharges  on  the  brain,  that  the  fits  may  ultimately
be  preceded  by  an  aura  identical  with  the  most  common  aura  of  idiopathic
epilepsy,  and  that  minor  attacks  may  become  developed  which  consist  only
of  loss  of  consciousness.
Pathology. — Very  few  observations  have  been  made  on  the  condition  of
the  brain  in  these  cases,  and  those  are  chiefly  on  cases  long  after  the  onset.
