Subtypes of Dementia

The subtypes that had been available in DSM-IV to qualify all dementias further (With Delirium, With Delusions, With Depressed Mood, Uncomplicated) are now only available for Vascular Dementia:

“By ICD-9-CM convention, Vascular Dementia is the only type of dementia that employs subtypes to indicate the presence of significant associated symptoms.” (p. 158)

“The specifier With Behavioral Disturbance (which cannot be coded) can also be used to indicate significant behavioral disturbances (e.g., wandering).” (p. 159)

Delusions are noted as common associated symptoms of Dementia (p. 150). Psychotic symptoms are noted as associated symptoms of Dementia of the Alzeheimer’s Type (p. 297).
