Abstract
Older people with immune disorders, chronic geriatric syndromes (especially frailty and dementia) and severe comorbidities represent a group with a higher risk of complications of all serious diseases, including COVID-19. One of these complications is delirium - an acute syndrome characterized by disturbances of consciousness and attention, perception, thinking, memory, psychomotor behavior, emotions and sleep rhythm.
Delirium significantly worsens the overall prognosis of the patient and has a high lethality. It occurs in 20-40% of hospitalized older patients, although it is a preventable condition.
Comprehensive preventive interventions can reduce the incidence of delirium by 40% and thus improve both the quality of life of patients and reduce the cost of care and treatment.
