AB Personality  disorders  are  characteristic  patterns  of  thinking,  feeling,  and  interpersonal  behavior  that  are  relatively  inflexible  and  cause  significant  functional  impairment  or  subjective  distress  for  the  individual.  The  observed  behaviors  are  not  secondary  to  another  mental  disorder,  nor  are  they  precipitated  by  substance  abuse  or  a  general  medical  condition.  This  distinction  is  often  difficult  to  make  in  clinical  practice,  because  personality  change  may  be  the  first  sign  of  serious  neurologic,  endocrine,  or  other  medical  illness.  Patients  with  frontal  lobe  tumors,  for  example,  can  present  with  changes  in  motivation  and  personality  while  the  results  of  the  neurologic  examination  remain  within  normal  limits.  Individuals  with  personality  disorders  are  often  regarded  as  “difficult  patients”  in  clinical  medical  practice  because  they  are  seen  as  excessively  demanding  and/or  unwilling  to  follow  recommended  treatment  plans.  Although  DSM-5  portrays  personality  disorders  as  qualitatively  distinct  categories,  there  is  an  alternative  and  emerging  perspective  that  personality  characteristics  vary  as  a  continuum  between  normal  functioning  and  formal  mental  disorder,  the  essential  features  being  moderate  or  greater  impairment  in  self/interpersonal  functioning  and  one  or  more  pathological  personality  traits.
