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   

ICD-11 Criteria for Dementia due to Alzheimer Disease (6D80) Dementia due to Alzheimer disease is the most common form of dementia. Onset is insidious with memory impairment typically reported as the initial presenting complaint. The characteristic course is a slow but steady decline from a previous level of cognitive functioning with impairment in additional cognitive domains (such as executive functions, attention, language, social cognition and judgment, psychomotor speed, visuoperceptual or visuospatial abilities) emerging with disease progression. Dementia due to Alzheimer disease may be accompanied by mental and behavioural symptoms such as depressed mood and apathy in the initial stages of the disease and may be accompanied by psychotic symptoms, irritability, aggression, confusion, abnormalities of gait and mobility, and seizures at later stages. Positive genetic testing, family history and gradual cognitive decline are suggestive of Dementia due to Alzheimer disease. Codin

ICD-11 Criteria for Amnestic Disorder (6D72) Prominent memory impairment relative to expectations for age and general premorbid level of cognitive functioning, which represents a decline from the individual’s previous level of functioning characterizes amnestic disorder, in the absence of other significant cognitive impairment. It is manifested by a deficit in acquiring, learning, and/or retaining new information, and may include the inability to recall previously learned information, without disturbance of consciousness, altered mental status, or delirium. Recent memory is typically more disturbed than remote memory, and the ability to immediately recall a limited amount of information is usually relatively preserved. The memory impairment is severe enough to result in significant impairment in personal, family, social, educational, occupational, or other important areas of functioning. It is is presumed to be attributable to an underlying acquired disease of the nervous system, a t

ICD-11 Criteria for Paraphilic Disorder Involving Solitary Behaviour or Consenting Individuals (6D36) Paraphilic disorder involving solitary behaviour or consenting individuals is characterised by a persistent and intense pattern of atypical sexual arousal— manifested by sexual thoughts, fantasies, urges, or behaviours— that involves consenting adults or solitary behaviours. One of the following two elements must be present: 1) the person is markedly distressed by the nature of the arousal pattern and the distress is not simply a consequence of rejection or feared rejection of the arousal pattern by others; or 2) the nature of the paraphilic behaviour involves significant risk of injury or death either to the individual or to the partner (e.g., asphyxophilia). 6D3Z          Paraphilic Disorders, Unspecified REFERENCE: International Classification of Diseases Eleventh Revision (ICD-11).

ICD-11 Criteria for Neurocognitive Disorders (BlockL1‑6D7) Neurocognitive disorders are characterised by primary clinical deficits in cognitive functioning that are acquired rather than developmental. That is, neurocognitive disorders do not include disorders characterised by deficits in cognitive function that are present from birth or that typically arise during the developmental period, which are classified in the grouping neurodevelopmental disorders. Rather, neurocognitive disorders represent a decline from a previously attained level of functioning. Although cognitive deficits are present in many mental disorders (e.g., schizophrenia, bipolar disorders), only disorders whose core features are cognitive are included in the neurocognitive Disorders grouping. In cases where the underlying pathology and etiology for neurocognitive disorders can be determined, the identified etiology should be classified separately. Exclusions: Neurodevelopmental disorders (BlockL1‑6A0) Coded E

ICD-11 Criteria for Factitious Disorder Imposed on Another (6D51) Factitious disorder imposed on another is characterised by feigning, falsifying, or inducing, medical, psychological, or behavioural signs and symptoms or injury in another person, most commonly a child dependent, associated with identified deception. If a pre-existing disorder or disease is present in the other person, the individual intentionally aggravates existing symptoms or falsifies or induces additional symptoms. The individual seeks treatment for the other person or otherwise presents him or her as ill, injured, or impaired based on the feigned, falsified, or induced signs, symptoms, or injuries. The deceptive behaviour is not solely motivated by obvious external rewards or incentives (e.g., obtaining disability payments or avoiding criminal prosecution for child or elder abuse). Coding Note:       The diagnosis of Factitious Disorder Imposed on Another is assigned to the individual who is feigning, falsifyi

ICD-11 Classification of Factitious Disorder BlockL1‑6D5 Factitious disorders are characterised by intentionally feigning, falsifying, inducing, or aggravating medical, psychological, or behavioural signs and symptoms or injury in oneself or in another person, most commonly a child dependent, associated with identified deception. A pre-existing disorder or disease may be present, but the individual intentionally aggravates existing symptoms or falsifies or induces additional symptoms. Individuals with factitious disorder seek treatment or otherwise present themselves or another person as ill, injured, or impaired based on the feigned, falsified, or self-induced signs, symptoms, or injuries. The deceptive behaviour is not solely motivated by obvious external rewards or incentives (e.g., obtaining disability payments or evading criminal prosecution). This is in contrast to Malingering, in which obvious external rewards or incentives motivate the behaviour. Exclusions:              Maling

ICD-11 Criteria for Mild Neurocognitive Disorder (6D71) Mild neurocognitive disorder is characterized by mild impairment in one or more cognitive domains relative to that expected given the individual’s age and general premorbid level of cognitive functioning, which represents a decline from the individual’s previous level of functioning. Diagnosis is based on report from the patient, informant, or clinical observation, and is accompanied by objective evidence of impairment by quantified clinical assessment or standardized cognitive testing. Cognitive impairment is not severe enough to significantly interfere with an individual’s ability to perform activities related to personal, family, social, educational, and/or occupational functioning or other important functional areas. Cognitive impairment is not attributable to normal aging and may be static, progressive, or may resolve or improve depending on underlying cause or treatment. Cognitive impairment may be attributable to an under

ICD-11 Criteria for Other Paraphilic Disorder Involving Non-Consenting Individuals (6D35) Other paraphilic disorder involving non-consenting individuals is characterised by a persistent and intense pattern of atypical sexual arousal— manifested by sexual thoughts, fantasies, urges, or behaviours— in which the focus of the arousal pattern involves others who are unwilling or unable to consent but that is not specifically described in any of the other named Paraphilic Disorders categories (e.g., arousal patterns involving corpses or animals). The individual must have acted on these thoughts, fantasies or urges or be markedly distressed by them. The disorder specifically excludes sexual behaviours that occur with the consent of the person or persons involved, provided that they are considered able to provide such consent.

ICD-11 Criteria for Prominent Personality Traits or Patterns (6D11) Trait domain qualifiers may be applied to Personality Disorders or Personality Difficulty to describe the characteristics of the individual’s personality that are most prominent and that contribute to personality disturbance. Trait domains are continuous with normal personality characteristics in individuals who do not have Personality Disorder or Personality Difficulty. Trait domains are not diagnostic categories, but rather represent a set of dimensions that correspond to the underlying structure of personality. As many trait domain qualifiers may be applied as necessary to describe personality functioning. Individuals with more severe personality disturbance tend to have a greater number of prominent trait domains. 6D11.0            Negative Affectivity in Personality Disorder or Personality Difficulty The core feature of the Negative Affectivity trait domain is the tendency to experience a broad range of nega

ICD-11 Criteria for Personality Disorder (6D10) Foundation URI : http://id.who.int/icd/entity/941859884 Description Personality disorder is characterised by problems in functioning of aspects of the self (e.g., identity, self-worth, accuracy of self-view, self-direction), and/or interpersonal dysfunction (e.g., ability to develop and maintain close and mutually satisfying relationships, ability to understand others’ perspectives and to manage conflict in relationships) that have persisted over an extended period of time (e.g., 2 years or more). The disturbance is manifest in patterns of cognition, emotional experience, emotional expression, and behaviour that are maladaptive (e.g., inflexible or poorly regulated) and is manifest across a range of personal and social situations (i.e., is not limited to specific relationships or social roles). The patterns of behaviour characterizing the disturbance are not developmentally appropriate and cannot be explained primarily by social or cult
