Pseudodementia: facts and figures
A Bulbena and GE Berrios
The historical and conceptual aspects of the pseudodementia state are
briefly touched upon. A "collective sample", composed of 61 cases culled
from the literature, is analysed and compared with the "Fulbourn sample"
consisting of 22 cases reported for the first time. Two sub- types of
pseudodementia emerge, one associated with depressive illness and the other
with delirium. A follow-up of the Fulbourn sample (1-4 years after
discharge) showed 14 patients to be alive and 8 to show no signs of
dementia. No variable except the diagnosis "non-specific psychosis"
correlated with death during the follow-up period.
