Q

Dissociative convulsions (psychogenic non-epileptic seizures)

A

Used to be known as ‘pseudoseizures’; however, the name has been changed because of concerns that the term ‘pseudo’ implies a degree of voluntary control (which is not the case). May present similarly to epileptic seizures but tongue-biting, serious injury and urinary incontinence are uncommon. There is also absence of epileptic activity on the electroencephalogram (EEG)

Q

Parke’s 5 stages of normal bereavement

A
  1. Alarm - highly stressed emotional state and physiological arousal (increased HR and BP)
  2. Numbness - a form of self-protection against the acute pain of loss
  3. Pining - being constantly reminded of, and preoccupied with, the deceased, with pangs of grief and intense anxiety
  4. Depression and despair - although most people will meet the criteria at some stage for a depressive episode, this should not be considered pathological
  5. Recovery and reorganisation - acceptance of loss, return to normal function, with grief only returning occasionally
20
Q

A
  1. Guilt (other than events surrounding the death)

  3. Preoccupation with worthlessness
  4. Marked psychomotor retardation
  5. Prolonged and marked functional impairment
  6. Hallucinatory experiences (other than transiently seeing or hearing the deceased)
