Neurocognitive disorders are characterised by primary clinical deficits in cognitive functioning that are acquired rather than developmental. This means that it is a change in behaviour rather than something that the person has always had or exhibited; it is noticed through a decline from a previously attained level of functioning or ability.
Previously, it was common to hear all disorders in this grouping referred to as Dementia, as that’s the term we most often associate with a decline in mental capacity, but Dementia is just one part of the group.
As mentioned, the categorisation does not include any disorders which also include deficits in cognitive function but which are present from birth or that develop during the developmental period of childhood. These are classified separately in the grouping neurodevelopmental disorders.
A further point to note about the grouping system is that 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.

It’s important to note that it is a change in behaviour that signifies the potential onset; a decline in cognitive function or a significant slow-down in ability when compared with previously.
