ICD-11 Criteria For Seasonal Pattern Of Mood Episode Onset

Foundation URI : http://id.who.int/icd/entity/822487798

ICD-11 Criteria For Seasonal Pattern Of Mood Episode Onset

6A80.4 

Description

In the context of recurrent depressive disorder, bipolar type I or bipolar type II disorder, there has been a regular seasonal pattern of onset and remission of at least one type of episode (i.e., depressive, manic, mixed, or hypomanic episodes), with a substantial majority of the relevant mood episodes corresponding to the seasonal pattern. (In bipolar type I and bipolar type II disorder, all types of mood episodes may not follow this pattern.) A seasonal pattern should be differentiated from an episode that is coincidental with a particular season but predominantly related to a psychological stressor that regularly occurs at that time of the year (e.g., seasonal unemployment).

Diagnostic Requirements

This specifier can be applied if:

  • In the context of Bipolar Type I or Bipolar Type II Disorder there has been a regular seasonal pattern of onset and remission of at least one type of episode (i.e., Depressive, Manic, Mixed, or Hypomanic Episodes); the other types of Mood Episodes may not follow this pattern; or
  • In the context of Recurrent Depressive Disorder there has been a regular seasonal pattern of onset and remission of Depressive Episodes.
  • A substantial majority of the relevant Mood Episodes should correspond with the seasonal pattern.
  • A seasonal pattern should be differentiated from an episode that is coincidental with a particular season but predominantly related to a psychological stressor that regularly occurs at that time of the year (e.g., seasonal unemployment).

ICD-11 Criteria for Rapid Cycling in Mood Disorder

ICD-11 Criteria for Rapid Cycling in Mood Disorder

 6A80.5

Description

In the context of bipolar type I or bipolar type II disorder, there has been a high frequency of mood episodes (at least four) over the past 12 months. There may be a switch from one polarity of mood to the other, or the mood episodes may be demarcated by a period of remission. In individuals with a high frequency of mood episodes, some may have a shorter duration than those usually observed in bipolar type I or bipolar type II disorder. In particular, depressive periods may only last several days. If depressive and manic symptoms alternate very rapidly (i.e., from day to day or within the same day), a mixed episode should be diagnosed rather than rapid cycling.

Diagnostic Requirements

This specifier can be applied if the Bipolar Type I or Bipolar Type II Disorder is characterized by a high frequency of Mood Episodes (at least four) over the past 12 months. There may be a switch from one polarity of mood to the other, or the Mood Episodes may be demarcated by a period of remission.

In individuals with a high frequency of Mood Episodes, some may have a shorter duration than those usually observed in Bipolar Type I or Bipolar Type II Disorder. In particular, depressive periods may only last several days. However, if depressive and manic symptoms alternate very rapidly (i.e., from day to day or within the same day), a Mixed Episode should be diagnosed rather than rapid cycling.

Diagnostic Requirements

This specifier can be applied if, in the context of a current Depressive Episode, several of the following symptoms have been present during the worst period of the current episode:

  • Loss of interest or pleasure in most activities that are normally enjoyable to the individual (i.e., pervasive anhedonia).

ICD-11 Criteria For Panic Attacks in Mood Episodes

Foundation URI : http://id.who.int/icd/entity/1383708356

ICD-11 Criteria For Panic Attacks in Mood Episodes

 6A80.1

Description

In the context of a current mood episode (manic, depressive, mixed, or hypomanic), there have been recurrent panic attacks (i.e., at least two) during the past month that occur specifically in response to anxiety-provoking cognitions that are features of the mood episode. If panic attacks occur exclusively in response to such thoughts, panic attacks should be recorded using this qualifier rather than assigning an additional co-occurring diagnosis of panic disorder. If some panic attacks over the course of the depressive or mixed episode have been unexpected and not exclusively in response to depressive or anxiety-provoking thoughts, a separate diagnosis of panic disorder should be assigned.

Exclusions

  • Panic disorder (6B01)

Diagnostic Requirements

This specifier can be applied if, in the context of a current Episode, there have been panic attacks during the past month that occur specifically in response to depressive ruminations or other anxiety-provoking cognitions. If panic attacks occur exclusively in response to such thoughts, the ‘with panic attacks’ specifier should be applied rather than an additional co-occurring diagnosis of Panic Disorder. If some panic attacks over the course of the Depressive or Mixed Episode have been unexpected and not exclusively in response to depressive or anxiety-provoking thoughts and the full diagnostic requirements for Panic Disorder are met, a separate diagnosis of Panic Disorder should be assigned.

ICD-11 Criteria for Prominent Anxiety Symptoms in Mood Episodes

Foundation URI : http://id.who.int/icd/entity/1119039346

Prominent Anxiety Symptoms in Mood Episodes

6A80.0

Description

In the context of a current depressive, manic, mixed, or hypomanic episode, prominent and clinically significant anxiety symptoms (e.g., feeling nervous, anxious or on edge, not being able to control worrying thoughts, fear that something awful will happen, having trouble relaxing, motor tension, autonomic symptoms) have been present for most of the time during the episode. If there have been panic attacks during a current depressive or mixed episode, these should be recorded separately. When the diagnostic requirements for both a mood disorder and an anxiety or fear-related disorder are met, the anxiety or fear-related disorder should also be diagnosed.

Diagnostic Requirements

This specifier can be applied if, in the context of a current Depressive, Manic, Mixed, or Hypomanic Episode, prominent and clinically significant anxiety symptoms (e.g., feeling nervous, anxious or on edge, not being able to control worrying thoughts, fear that something awful will happen, having trouble relaxing, muscle tension, autonomic symptoms) have been present for most of the time during the episode. If there have been panic attacks during the current Depressive or Mixed Episode, these should be recorded separately (see ‘with panic attacks’ specifier). This specifier may be used whether or not the diagnostic requirements for an Anxiety or Fear-Related Disorder are also met, in which case the Anxiety or Fear-Related Disorder should also be diagnosed.

ICD-11 Criteria for Other Specified Depressive Disorders

ICD-11 Criteria for Other Specified Depressive Disorders

6A7Y 

Essential (Required) Features:

  • The presentation is characterized by mood symptoms that share primary clinical features with other Depressive Disorders (e.g., depressed mood, decreased engagement in pleasurable activities, decreased energy levels, disruptions in sleep or eating).
  • The symptoms do not fulfil the diagnostic requirements for any other disorder in the Depressive Disorders grouping.
  • The symptoms are not better accounted for by another Mental, Behavioural or Neurodevelopmental Disorder (e.g., Schizophrenia or Other Primary Psychotic Disorder, an Anxiety or Fear-Related Disorder, a Disorder Specifically Associated with Stress).
  • The symptoms and behaviours are not a manifestation of another medical condition and are not due to the effects of a substance or medication (e.g., alcohol, benzodiazepine) on the central nervous system, including withdrawal effects (e.g., from cocaine).
  • The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning. If functioning is maintained, it is only through significant additional effort.

ICD-11 Criteria for Adjustment Disorder (6B43)

ICD-11 Criteria for Adjustment disorder (6B43)

Adjustment disorder is a maladaptive reaction to an identifiable psychosocial stressor or multiple stressors (e.g. divorce, illness or disability, socio-economic problems, conflicts at home or work) that usually emerges within a month of the stressor. The disorder is characterised by preoccupation with the stressor or its consequences, including excessive worry, recurrent and distressing thoughts about the stressor, or constant rumination about its implications, as well as by failure to adapt to the stressor that causes significant impairment in personal, family, social, educational, occupational or other important areas of functioning. The symptoms are not better explained by another mental disorder (e.g., Mood Disorder, another Disorder Specifically Associated with Stress) and typically resolve within 6 months, unless the stressor persists for a longer duration.

Exclusions:             

  • Separation anxiety disorder of childhood (6B05)
  • Recurrent depressive disorder (6A71)
  • Single episode depressive disorder (6A70)
  • Prolonged grief disorder (6B42)
  • Uncomplicated bereavement (QE62)
  • Burnout (QD85)
  • Acute stress reaction (QE84)
