Aim: To compare the symptom profile of patients with delirium without preexisting cognitive deficits and those experiencing delirium in the background of preexisting cognitive deficits. Materials and Methods: A total of 107 patients aged ≥60 years with diagnosis of delirium as per the Diagnostic and Statistical Manual, IV text revision criteria were evaluated on Short Informant Questionnaire on Cognitive Decline in the Elderly (Short IQCODE), Delirium Rating Scale Revised 98 version (DRS-R98), amended delirium motor symptom scale, and delirium etiology checklist and risk factor checklist. On the basis of short IQCODE score, the study sample was divided into those with (≥3.5) and without cognitive deficits and were compared for the symptom profile, motor subtype, risk factors, and etiologies. Results: Based on the short IQCODE scores, the patients were divided into those with (≥3.5) and without cognitive deficits (<3.5). Those with cognitive deficits (n = 20) were significantly older and more often had delirium prior to getting admitted to the hospital. The groups did not differ in terms of frequency and severity of various symptoms of delirium, DRS-R98 total score, DRS-R98 severity score, DRS-R98 cognitive domain score, DRS-R98 noncognitive domain score, motor subtypes, various risk factors, various associated etiologies, mean number of risk factors for delirium, and mean number of associated etiologies. There was no association between mean IQCODE score and severity scores for each symptom of delirium as per DRS-R98, DRS-R98 total score, DRS-R98 severity score, DRS-R98 cognitive domain score, and DRS-R98 noncognitive domain score. Conclusion: There is no difference in the symptom profile of those with and without preexisting cognitive deficits.
