ICD-11 Criteria for Dissociative Amnesia (6B61)

ICD-11 Criteria for Dissociative Amnesia (6B61)

Dissociative amnesia is characterised by an inability to recall important autobiographical memories, typically of recent traumatic or stressful events, that is inconsistent with ordinary forgetting. The amnesia does not occur exclusively during another dissociative disorder and is not better explained by another mental, behavioural or neurodevelopmental disorder. The amnesia is not due to the direct effects of a substance or medication on the central nervous system, including withdrawal effects, and is not due to a disease of the nervous system or to head trauma. The amnesia results in significant impairment in personal, family, social, educational, occupational or other important areas of functioning.


  • Amnesia NOS (MB21.1)
  • Amnestic disorder due to use of alcohol (6D72.10)
  • Anterograde amnesia (MB21.10)
  • Retrograde amnesia (MB21.11)
  • Nonalcoholic organic amnesic syndrome (6D72.0)
  • Postictal amnesia in epilepsy (BlockL1‑8A6)

6B61.0     Dissociative amnesia with dissociative fugue

Dissociative amnesia with dissociative fugue is characterised by all of the features of Dissociative Amnesia, accompanied by dissociative fugue, i.e., a loss of a sense of personal identity and sudden travel away from home, work, or significant others for an extended period of time (days or weeks). A new identity may be assumed.


  • Postictal fugue in epilepsy (BlockL1‑8A6)

6B61.1    Dissociative amnesia without dissociative fugue

Dissociative amnesia without dissociative fugue is characterised by all of the features of dissociative amnesia occurring in the absence of symptoms of dissociative fugue.

ADVOKATE: A Mnemonic Tool for the Assessment of Eyewitness Evidence

ADVOKATE: A Mnemonic Tool for Assessment of Eyewitness Evidence A tool for assessing eyewitness  ADVOKATE is a tool designed to assess eyewitness evidence and how much it is reliable. It requires the user to respond to several statements/questions. Forensic psychologists, police or investigative officer can do it. The mnemonic ADVOKATE stands for: A = amount of time under observation (event and act) D = distance from suspect V = visibility (night-day, lighting) O = obstruction to the view of the witness K = known or seen before when and where (suspect) A = any special reason for remembering the subject T = time-lapse (how long has it been since witness saw suspect) E = error or material discrepancy between the description given first or any subsequent accounts by a witness.  Working with suspects (

ICD-11 Criteria for Anorexia Nervosa (6B80)

ICD-11 Criteria for Anorexia Nervosa (6B80) Anorexia Nervosa is characterised by significantly low body weight for the individual’s height, age and developmental stage that is not due to another health condition or to the unavailability of food. A commonly used threshold is body mass index (BMI) less than 18.5 kg/m2 in adults and BMI-for-age under 5th percentile in children and adolescents. Rapid weight loss (e.g. more than 20% of total body weight within 6 months) may replace the low body weight guideline as long as other diagnostic requirements are met. Children and adolescents may exhibit failure to gain weight as expected based on the individual developmental trajectory rather than weight loss. Low body weight is accompanied by a persistent pattern of behaviours to prevent restoration of normal weight, which may include behaviours aimed at reducing energy intake (restricted eating), purging behaviours (e.g. self-induced vomiting, misuse of laxatives), and behaviours aimed at incr

ICD-11 Criteria for Schizophrenia (6A20 )

ICD-11 Criteria for Schizophrenia (6A20 ) Schizophrenia is characterised by disturbances in multiple mental modalities, including thinking (e.g., delusions, disorganisation in the form of thought), perception (e.g., hallucinations), self-experience (e.g., the experience that one's feelings, impulses, thoughts, or behaviour are under the control of an external force), cognition (e.g., impaired attention, verbal memory, and social cognition), volition (e.g., loss of motivation), affect (e.g., blunted emotional expression), and behaviour (e.g., behaviour that appears bizarre or purposeless, unpredictable or inappropriate emotional responses that interfere with the organisation of behaviour). Psychomotor disturbances, including catatonia, may be present. Persistent delusions, persistent hallucinations, thought disorder, and experiences of influence, passivity, or control are considered core symptoms. Symptoms must have persisted for at least one month in order for a diagnosis of schi
