Introduction. There is a lot of evidence that coronavirus disease 2019 has
various manifestations. This paper presents a report of two cases with the
aim to indicate the multifactorial etiology of confusional states in
patients with mental disorders at the time coronavirus disease 2019
pandemic. The severe acute respiratory syndrome coronavirus-2 affects not
only the respiratory and cardiovascular systems, but also the brain, kidneys
and other organ systems. One of the first manifestations of this infection
can be mental confusion. Case Study. The first patient, a woman diagnosed
with schizoaffective psychosis, suddenly presented with confusion, followed
by hypersedation which was at first attributed to overmedication. In another
patient, with the diagnosis of bipolar affective disorder, sudden confusion
(delirium) was initially recognized as an element of mental disorder
deterioration. A more detailed observation revealed that the confused state
in both patients was caused by severe acute respiratory syndrome
coronavirus-2 infection. Discussion. It is common for the manifestations of
severe acute respiratory syndrome coronavirus-2 infection to include
respiratory and cardiovascular syimptoms. However, symptoms related to other
organs and organ systems, including changes in neurological and
psychological status, should not be ignored. Conclusion. It was noticed that
confusion and delirium-like states are quite common early symptoms of
coronavirus disease 2019. In psychiatric patients, it is always necessary to
rule out the organic etiology of the consciousness disorder and immediately
proceed with the diagnostic procedures. One should certainly keep in mind
that diagnostic errors are possible, not only due to various manifestations
of the infection, but also due to the stigmatization of mental illness,
which must be overcome in order to provide the best possible treatment
effects.
