• Name 3 problems pt. experience when confabulating

  1. Confabulation can obstruct neuropsychological management and rehabilitation (failing to see why it is necessary)
  
  2. Reduced ability independent living and increased need supervision
  
  3. Creates difficulties in pt. social environment

• What function can confabulation help to infer cognitive models about?

  Memory

• How do they explain the existence of confabulation?

  Confabulations seen as neurogenic exaggerations of the previously imperfect and dynamic functions serving personal memory and self-awareness. Moreover: despite poor correspondence reality, confabulations represent attempts to define one’s self in time and relation to world (subject to motivational influences and serve important identity formation functions)

• In what diseases do we often see confabulation? Name 4.

  1. Wernicke-Korsakoff syndrome
  
  2. anterior communicating artery aneurysms
  
  3. Alzheimer’s disease
  
  4. traumatic brain injury

• Lesions in which areas of the brain are associated with confabulation? Name 5.

  1. ventromedial PFC
  
  2. OFC
  
  3. basal forebrain
  
  4. anterior cingulate cortex
  
  5. other anterior limbic areas

• Impairment in what domain is necessary for confabulation to occur?

  Executive functioning

• There are two main classes of theory on why confabulation occurs. Explain them shortly.

  1. Focusing on impaired temporality or reality monitoring
  
  2. deficits in control of memory rerieval

• Explain the theory of impaired temporality or reality monitoring in confabulation

  Suggested pt. have disturbed ability of determining chronology. Pt. are unable to distinguish temporal or spatial source of different memories (source monitoring) or distinguish between real events and imagined ones (reality monitoring)

• Explain the theory on deficit in memory retrieval in confabulation

  Deficit in control of memory retrieval. When memories are not elicited directly or automatically by a cue, a number of control processes, memory search and monitoring processes are called for to guide recollection. Confabulation represents failure in one or more of these processes.

• Which cognitive abilities can be improved in management and rehabilitation of confabulation in pt.?

  Amnesia, executive functioning, source monitoring, strategic retrieval deficits
