ICD-11 Criteria for Symptomatic Manifestations of Primary Psychotic Disorders (6A25)

These categories may be used to characterize the current clinical presentation in individuals diagnosed with Schizophrenia or another primary psychotic disorder, and should not be used in individuals without such a diagnosis. Multiple categories may be applied. Symptoms attributable to the direct pathophysiological consequences of a health condition or injury not classified under Mental, behavioural or neurodevelopmental disorders (e.g., a brain tumour or traumatic brain injury), or to the direct effects of a substance or medication on the central nervous system, including withdrawal effects, should not be considered as examples of the respective types of symptoms.

Coding Note:     These categories should never be used in primary coding. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of these symptoms in primary psychotic disorders.

6A25.0       Positive symptoms in primary psychotic disorders

Positive symptoms in primary psychotic disorders include persistent delusions, persistent hallucinations (most commonly verbal auditory hallucinations), disorganised thinking (formal thought disorder such as loose associations, thought derailment, or incoherence), grossly disorganised behaviour (behaviour that appears bizarre, purposeless and not goal-directed) and experiences of passivity and control (the experience that one's feelings, impulses, or thoughts are under the control of an external force). The rating should be made based on the severity of positive symptoms during the past week.

Coding Note:     Code aslo the causing condition

6A25.1      Negative symptoms in primary psychotic disorders

Negative symptoms in primary psychotic disorders include constricted, blunted, or flat affect, alogia or paucity of speech, avolition (general lack of drive, or lack of motivation to pursue meaningful goals), asociality (reduced or absent engagement with others and interest in social interaction) and anhedonia (inability to experience pleasure from normally pleasurable activities). To be considered negative psychotic symptoms, relevant symptoms should not be entirely attributable to antipsychotic drug treatment, a depressive disorder, or an under-stimulating environment, and should not be a direct consequence of a positive symptom (e.g., persecutory delusions causing a person to become socially isolated due to fear of harm). The rating should be made based on the severity of negative symptoms during the past week.

Coding Note:     Code aslo the causing condition

6A25.2       Depressive mood symptoms in primary psychotic disorders

Depressive mood symptoms in primary psychotic disorders refer to depressed mood as reported by the individual (feeling down, sad) or manifested as a sign (e.g. tearful, defeated appearance). If only non-mood symptoms of a depressive episode are present (e.g., anhedonia, psychomotor slowing), this descriptor should not be used. This descriptor may be used whether or not depressive symptoms meet the diagnostic requirements of a separately diagnosed Depressive disorder. The rating should be made based on the severity of depressive mood symptoms during the past week.

Coding Note:     Code aslo the causing condition

6A25.3      Manic mood symptoms in primary psychotic disorders

Manic mood symptoms in primary psychotic disorders refer to elevated, euphoric, irritable, or expansive mood states, including rapid changes among different mood states (i.e., mood lability). It also includes increased subjective experience of energy, which may be accompanied by increased goal-directed activity. The severity of associated non-mood symptoms of a Manic or Hypomanic Episode (e.g., decreased need for sleep, distractibility) should not be considered in making a rating. Increased non-goal-directed psychomotor activity should be considered as part of the rating of the 'psychomotor symptoms in primary psychotic disorders' rather than here. This descriptor may be used whether or not the manic symptoms meet the diagnostic requirements of a separately diagnosed bipolar disorder. The rating should be made based on the severity of manic mood symptoms during the past week.

Coding Note:     Code aslo the causing condition

6A25.4      Psychomotor symptoms in primary psychotic disorders

Psychomotor symptoms in primary psychotic disorders include psychomotor agitation or excessive motor activity, usually manifested by purposeless behaviours such as fidgeting, shifting, fiddling, inability to sit or stand still, wringing of the hands, psychomotor retardation, or a visible generalised slowing of movements and speech, and catatonic symptoms such as excitement, posturing, waxy flexibility, negativism, mutism, or stupor. The rating should be made based on the severity of psychomotor symptoms during the past week.

Coding Note:     Code aslo the causing condition

6A25.5     Cognitive symptoms in primary psychotic disorders

Cognitive symptoms in primary psychotic disorders refer to cognitive impairment in any of the following domains: speed of processing, attention/concentration, orientation, judgment, abstraction, verbal or visual learning, and working memory. The cognitive impairment is not attributable to a neurodevelopmental disorder, a delirium or other neurocognitive disorder, or the direct effects of a substance or medication on the central nervous system, including withdrawal effects. Ideally, use of this category should be based on the results of locally validated, standardized neuropsychological assessments, although such measures may not be available in all settings. The rating should be made based on the severity of cognitive symptoms during the past week.

Coding Note:     Code aslo the causing condition

Exclusions:             

  • Neurocognitive disorders (BlockL1‑6D7)
  • Neurodevelopmental disorders (BlockL1‑6A0)

  6A2Y      Other specified primary psychotic disorder

  6A2Z       Schizophrenia or other primary psychotic disorders, unspecified

ADVOKATE: A Mnemonic Tool for the Assessment of Eyewitness Evidence

By
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 (college.police.uk)

ICD-11 Criteria for Attention Deficit Hyperactivity Disorder (ADHD) 6A05

By
ICD-11 Criteria for Attention Deficit Hyperactivity Disorder (ADHD) 6A05 Attention deficit hyperactivity disorder is characterised by a persistent pattern (at least 6 months) of inattention and/or hyperactivity-impulsivity that has a direct negative impact on academic, occupational, or social functioning. There is evidence of significant inattention and/or hyperactivity-impulsivity symptoms prior to age 12, typically by early to mid-childhood, though some individuals may first come to clinical attention later. The degree of inattention and hyperactivity-impulsivity is outside the limits of normal variation expected for age and level of intellectual functioning. Inattention refers to significant difficulty in sustaining attention to tasks that do not provide a high level of stimulation or frequent rewards, distractibility and problems with organisation. Hyperactivity refers to excessive motor activity and difficulties with remaining still, most evident in structured situations that re...

ICD-11 Criteria for Anorexia Nervosa (6B80)

By
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...
