Answer

Patients who are initially identified as having PAF may have underlying pathology consistent with MSA or Parkinson's disease, or they may be found to have AAN after extensive testing. Involvement of the intermediolateral cell column with the loss of small sympathetic neurons has been observed in some patients.
