[Delirium in the "young" covid-19 patient (<65 years): preliminary clinical indications]. / Il delirium nel paziente covid-19 "giovane" (<65 anni): indicazioni cliniche preliminari.

Delirium is a phenomenon classified within neuro-cognitive disorders in the DSM-5. It has several etiologies and it is often lethal. This contribute aims at analyzing clinical characteristics and diagnostic possibilities of delirium in patients affected by covid-19. Furthermore, some preliminary recommendations on the use of psychopharmacological treatment of delirium and their interactions with main drugs used to treat covid-19 are given, with a special attention to comorbidities like in immunocompromised patients, in those affected by diabetes and cancer, in pregnant women or in addicted clients.

Cognitive impairment in late life bipolar disorder: Risk factors and clinical outcomes.

BACKGROUND: Late Life Bipolar Disorder (LLBD) is associated with a high prevalence of cognitive impairments, but few studies have examined their risk factors and clinical correlates METHODS: Participants with bipolar disorder older than 60 (n = 86) were recruited from psychiatric outpatient and inpatients units. Patients were assessed with various instruments, including the Clinical Dementia Rating scale, the Montreal Cognitive Assessment and the Cumulative Illness Rating Scale. The distribution of disorder-specific and general risk factors was compared between patients with LLBD plus cognitive impairments (mild cognitive impairment or dementia) and those with LLBD but no cognitive impairment. Analyses were first conducted at the bivariate level, then using multiple regression. The association with disability, aggressive behavior and suicidal ideation was also explored. RESULTS: Cognitive impairments in LLBD were associated with a diagnosis of type 1 bipolar disorder (OR = 6.40, 95%CI: 1.84 - 22.31, p = 0.004), fewer years of education (OR = 0.79, 95%CI: 0.69 - 0.91, p = 0.001) and higher severity of physical diseases (OR 26.54, 95%CI: 2.07 - 340.37, p = 0.01). Moreover, cognitive impairments were associated with an increased likelihood of disability and recent aggressive behavior, but not suicidal ideation. LIMITATIONS: retrospective design, conflation of MCI and dementia, not all subjects were in euthymia CONCLUSIONS: In LLBD, the presence of cognitive impairments was associated with a diagnosis of type I bipolar disorder, lower education and more severe physical comorbidities. In turn, MCI or dementia were associated with increased disability and aggressive behavior. These findings may aid the identification of patients at risk for cognitive deterioration in everyday clinical practice.
