title: To know or not to know: a review of behaviour and suicidal ideation in preclinical Huntington's disease.
abstract: OBJECTIVE
  At present, the problems associated with suicidal ideation and suicide in Huntington's disease (HD), worldwide, are much the same as 2 decades ago. This study seeks to investigate the psychological complications of predictive testing in HD at risk populations.
  
  
  METHODS
  The key problems of predictive testing, fear of acquiring carrier status, psychological consequences, autonomy, and rights to know are discussed.
  
  
  RESULTS
  This review (1) describes psychological affect and problems of persons facing the decision to test for HD, (2) discusses suicidal ideation, behaviour, and catastrophic events associated with predictive testing, (3) assesses ethical questions raised in the genetic counselling, (4) questions whether counsellors should promote or advocate predictive testing, and finally (5) discusses what professionalism actually is in genetic counselling.
  
  
  CONCLUSIONS
  The need for professional counselling, using a well designed protocol, and the importance of focusing on the suicide risk of participants in predictive testing programs are emphasized.
  
  
  CONCLUSIONS
  The counsellor has an obligation to provide adequate information. The professionals should not promote nor advocate presymptomatic DNA-testing. Depression, hopelessness, anxiety, emotional distress, suicidal tendencies, and social dysfunction grading should be considered in predictive testing of HD.
