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
