Background and aims: We investigated cognitive and affective disorders in patients with SARS-CoV-2 hospitalized in Intensive Care Unit (ICU). Care givers quality of life, psychological distress and satisfaction with the information received by health-care professionals were assessed. Methods: From March 1 to April 30, 2020, 22 consecutive patients with SARS-CoV-2 infection, confirmed by PCR on oronasopharyngeal swab, requiring ICU admission were recruited together with a caregiver. Patients with previous cognitive disorders were excluded. Three months after ICU discharge, patients underwent a comprehensive neuropsychological evaluation and filled out validated questionnaires. Results: Seven of 22 resulted mildly cognitively impaired. Memory was the most impaired domain, followed by attention and verbal fluency. Three out of 22 patients reported an average high level of anxiety but no depression. Quality of life was mild impaired for 19 patients. Lower performances at MoCA were related to higher APACHE score at T0 (r = −.44;p −.48;ps −.53;ps −.53;ps

BACKGROUND The long-term effect of liver transplantation (LT) on cognitive functions and the complete reversibility of minimal hepatic encephalopathy are poorly documented. Much evidence indicates that spatial attention improves starting from the immediate period after LT. However, at least in the first 2 years, some cognitive defects seem to persist to some degree, especially for supramodal nonverbal cognitive functions. The aim of this study is to investigate (i) whether the improvements observed in the perioperative period fluctuate or remain stable 10 years after LT and (ii) whether the functions that have been found defective also improve. METHODS We called patients previously included in a prospective study (Mattarozzi et al., Arch Neurol 2004; 61: 242) for a further neuropsychological evaluation. We compared the cognitive evaluation after 7 to 10 years with previous data gathered 6 and 18 months after LT. RESULTS The improvements obtained in the first 2 years after transplantation remain stable during the 7 to 10 years thereafter, especially for visuospatial attention, F(12,96) 1.70; P=0.04 and selective attention, F(6,66) 3.51; P=0.005. Furthermore, these findings also seem to suggest an improvement in supramodal cognitive functions, such as spatial planning intelligence, measured by the Elithorn Maze Test, F(3,33) 7.42; P=0.002. Verbal short-term memory, F(3,33) 3.69; P=0.038, and visuospatial short-term memory, F(6,64) 2.97; P=0.013, show a more fluctuating trend over time. CONCLUSIONS Despite the risk of surgery, the neurotoxicity of immunosuppression therapy, and the effects of aging and related comorbidities, our data indicate that LT is able to significantly improve patients' cognitive functions in the long term.

Objective.To describe a patient with a new onset bipolar disorder (BD) type II, secondary to a lacunar state.Background.Poststroke BD is rare and mainly associated with lesion in the prefrontal-striatal-thalamic circuit.Materials and Methods.A 51-year-old woman came to our attention for a mood disorder of recent onset. At 49, she had suffered acute left-sided limb weakness that improved spontaneously four days later. Arterial hypertension was subsequently diagnosed. After 6 months, she began to suffer from alternating brief periods of expansive and elevated mood with longer periods of depressed mood, with a suicide attempt. We performed extensive laboratory and instrumental investigations, as well as, psychiatric consultation, and a cognitive assessment, which was repeated 9 months later.Results.Brain magnetic resonance disclosed leukoaraiosis and a lacunar state of the basal ganglia. Transcranial Doppler showed a patent foramen ovale. A psychiatric consultation led to the diagnosis of BP type II. Neuropsychological evaluation detected deficits in attention/executive functions, verbal fluency, and memory. Nine months later, after specific psychiatric therapy, the psychiatric symptoms were remarkably improved.Conclusion.Our case sheds light on the role of the basal ganglia in mood disorders and the importance of ruling out brain injury in late onset BP.

Three cirrhotic patients with chronic acquired hepatocerebral degeneration (CAHD) received neurologic, neuropsychologic and neuroimaging assessment before and after liver transplantation (LT). Before transplantation, neurologic dysfunction consisted in severe bradykinesia, dystonia, dyskinesia, ataxia and dysarthria. Cognitive impairment affected mainly attentional and executive domains. Brain MRI showed bilateral hyperintensities of the basal ganglia on T1-weighted images. After transplantation, motor manifestations promptly resolved. Cognitive testing showed a major improvement in two patients, whereas cognitive performances were slightly worsened in the third, reasonably due to the effects of a head injury before LT and a tacrolimus-related encephalopathy arising early after LT. MRI images 12 months later showed a slight reduction of the previously disclosed abnormalities in all three patients. None of them experienced recurrence of CAHD. Our observation reinforces the assumption that surgery is the best treatment option for CAHD and that severe neurological impairment in CAHD should not be considered a contraindication for LT.
