ICD-11 code : L1-6D7;
Preferred Label : Neurocognitive disorders;
ICD-11 definition : 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 aetiology for neurocognitive
disorders can be determined, the identified etiology should be classified separately.;
