ICD-11 Criteria for Mental or Behavioural Disorders Associated with Pregnancy, Childbirth or the Puerperium (BlockL1‑6E2) Syndromes associated with pregnancy or the puerperium (commencing within about 6 weeks after delivery) that involve significant mental and behavioural features. If the symptoms meet the diagnostic requirements for a specific mental disorder, that diagnosis should also be assigned. Coded Elsewhere:   Psychological disorder related to obstetric fistula (GC04.1Y) 6E20      Mental or Behavioural Disorders Associated with Pregnancy, Childbirth or the Puerperium, without Psychotic Symptoms A syndrome associated with pregnancy or the puerperium (commencing within about 6 weeks after delivery) that involves significant mental and behavioural features, most commonly depressive symptoms. The syndrome does not include delusions, hallucinations, or other psychotic symptoms. If the symptoms meet the diagnostic requirements for a specific mental disorder, that diagnosis s

ICD-11 Criteria for Behavioural or Psychological Disturbances in Dementia (6D86) In addition to the cognitive disturbances characteristic of dementia, the current clinical picture includes clinically significant behavioural or psychological disturbances. Coding Note:       These categories should never be used in primary tabulation. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of behavioural or psychological disturbance in dementia. Code all that apply. Exclusions: Secondary mental or behavioural syndromes associated with disorders or diseases classified elsewhere (BlockL1‑6E6) 6D86.0         Psychotic Symptoms in Dementia In addition to the cognitive disturbances characteristic of dementia, the current clinical picture includes clinically significant delusions or hallucinations. Exclusions:               Schizophrenia or other primary psychotic disorders (BlockL1‑6A2) Secondary psychotic syndrome (6E61)

ICD-11 Criteria for Dementia due to Diseases Classified Elsewhere (6D85 ) Coding Note:       This category should never be used in primary tabulation. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of dementia in diseases classified elsewhere. When dementia is due to multiple aetiologies, code all that apply. 6D85.0          Dementia due to Parkinson disease Dementia due to Parkinson disease develops among individuals with idiopathic Parkinson disease and is characterized by impairment in attention, memory, executive and visuo-spatial functions. Mental and behavioral symptoms such as changes in affect, apathy and hallucinations may also be present. Onset is insidious and the course is one of gradual worsening of symptoms. Coding Note:       This category should never be used in primary tabulation. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of d

ICD-11 Criteria for Dementia due to Cerebrovascular Disease (6D81) Dementia due to brain parenchyma injury resulting from cerebrovascular disease (ischemic or haemorrhagic). The onset of the cognitive deficits is temporally related to one or more vascular events. Cognitive decline is typically most prominent in speed of information processing, complex attention, and frontal-executive functioning. There is evidence of the presence of cerebrovascular disease considered to be sufficient to account for the neurocognitive deficits from history, physical examination and neuroimaging. Coding Note:       This category should never be used in primary tabulation. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of dementia in diseases classified elsewhere. Exclusions: Alzheimer disease dementia, mixed type, with cerebrovascular disease (6D80.2) REFERENCE: International Classification of Diseases Eleventh Revision (ICD-11). Gene

ICD-11 Criteria for Frontotemporal Dementia (6D83) Frontotemporal dementia (FTD) is a group of primary neurodegenerative disorders primarily affecting the frontal and temporal lobes. Onset is typically insidious with a gradual and worsening course. Several syndromic variants (some with an identified genetic basis or familiality) are described that include presentations with predominantly marked personality and behavioral changes (such as executive dysfunction, apathy, deterioration of social cognition, repetitive behaviours, and dietary changes),predominantly language deficits (that include semantic, agrammatic/nonfluent, and logopenic forms), predominantly movement-related deficits (progressive supranuclear palsy, corticobasal degeneration, multiple systems atrophy, or amyotrophic lateral sclerosis), or a combination of these deficits. Memory function, often remains relatively intact, particularly during the early stages of the disorder. Coding Note:       This category should nev

ICD-11 Criteria for Dementia Due to Lewy Body Disease (6D82) Dementia preceding or occurring within one year after the onset of motor parkinsonian signs in the setting of Lewy body disease. Characterized by presence of Lewy bodies, which are intraneuronal inclusions containing α-synuclein and ubiquitin in the brain stem, limbic area, forebrain, and neocortex. Onset is insidious with attentional and executive functioning deficits often present. These cognitive deficits are often accompanied by visual hallucinations and symptoms of REM sleep behaviour disorder. Hallucinations in other sensory modalities, depressive symptoms, and delusions may also be present. The symptom presentation usually varies significantly over the course of days necessitating longitudinal assessment and differentiation from delirium. Spontaneous onset of Parkinsonism within approximately 1 year of the onset of cognitive symptoms is common. Coding Note:       This category should never be used in primary tabula

ICD-11 Criteria for Dementia due to Psychoactive Substances Including Medications (6D84) Dementia due to psychoactive substances including medications includes forms of dementia that are judged to be a direct consequence of substance use and that persist beyond the usual duration of action or withdrawal syndrome associated with the substance. The amount and duration of substance use must be sufficient to produce the cognitive impairment. The cognitive impairment is not better accounted for by a disorder that is not induced by substances such as a dementia due to another medical condition. Coding Note:       This category should never be used in primary tabulation. The codes are provided for use as supplementary or additional codes when it is desired to identify the presence of dementia in diseases classified elsewhere. When dementia is due to multiple aetiologies, code all that apply. Exclusions:     Dementia due to exposure to heavy metals and other toxins (6D85.2) 6D84.0
