Background: During the pandemic, many neurological symptoms have been evaluated as complications of COVID-19 pneumonia., Objective: To investigate the frequency and characteristics of neurological findings, and their effects on the prognosis of patients with COVID-19 pneumonia who consulted with the Neurology department., Methods: Data on 2329 patients who were hospitalized with the diagnosis of COVID-19 pneumonia in our hospital were scanned. The clinical, laboratory and radiological findings relating to treatment of 154 patients who required neurological consultation were retrospectively evaluated by reviewing the clinical notes., Results: The number of COVID-19 pneumonia patients who required neurological consultations while hospitalized in the ICU was 94 (61.0%). The most common symptom among these patients was hyperactive delirium. Mean age, ferritin levels and CRP values ​​of those with delirium were higher, while the mean lymphocyte percentage were lower, than those of the patients without delirium. Epileptic seizures were observed in eight patients without an epilepsy diagnosis. Two patients were diagnosed with GBS and one patient with ICU neuropathy. The D-dimer levels of patients with acute hemorrhagic CVD and the thrombocyte levels of patients with acute ischemic CVD were found to be higher than in patients without acute ischemic CVD., Conclusion: The proportion of patients who required neurological consultations was higher in the ICUs. We observed neurological symptoms more frequently in the advanced age group. There were no significant increases in the incidence of other neurological conditions except delirium, in COVID-19 patients. We think that further studies are needed to support our data.

Background: Elevated levels of chemerin can predict future ischemic cerebrovascular disease. Although chemerin is thought to play a role in atherosclerotic inflammation, whether circulating chemerin levels are associated with the severity of atherosclerosis remains to be determined., Objectives: Through the use of carotid Doppler ultrasonography, our aim in this study was to investigate the relationships of serum chemerin levels with carotid intima-media thickness (CIMT) as an indicator of generalized atherosclerosis., Methods: This study compared 40 patients with ischemic stroke and 40 healthy subjects. Measurements were made at end-diastole using color Doppler ultrasonography (CDUS) after a 5-min rest interval in a quiet and dark room. CIMT was defined as the distance between the innermost edge of the luminal echo to the innermost edge of the media/adventitia echo. CIMT was measured in the posterior wall of both common carotid arteries within 1 cm proximally to the bulbus. Three measurements were made on both sides and the average measurement was taken as the CIMT. Serum chemerin levels were determined in all patients and healthy subjects., Results: Serum chemerin levels were significantly higher in the patient group than in the control group (p=0.004). Serum chemerin levels were positively correlated with CIMT (p<0.05). There was a significant difference between the groups with regard to CIMT (p<0.001)., Conclusion: Elevated serum chemerin levels appear to be associated with CIMT, thus suggesting that a link exists between chemerin and atherosclerotic ischemic cerebrovascular disease.

Background: This study reported on a variety of psychological reactions related to anxiety, sleep quality, depression, fatigue, and quality of life in individuals with multiple sclerosis (MS), related to the Covid-19 quarantine experience., Objective: The aim of this study was to investigate the neuropsychiatric effects of the COVID-19 pandemic in MS patients and to analyze the risk factors contributing to psychological stress., Methods: The study was designed as a prospective, cross-sectional survey study. Multiple assessment tools that are used in neurological practice, including Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Fatigue Impact Scale (FIS), Pittsburgh Sleep Quality Index (PSQI), and Multiple Sclerosis Quality of Life-54 (MSQOL-54) were administered prospectively both during the early and the peak stages of COVID-19 outbreak (ESO and PSO, respectively). The survey forms were designed using SurveyMonkey and the participants were participating in the survey via a web link and QR code., Results: Fifty patients were included in the study. BDI scores, PSQI and FSI measurements, cognitive and social subscale scores and total FIS score, MSQOL-54 measurements, physical and mental subscale scores, and total MSQOL-54 score at PSO were significantly different than those at ESO. The body mass index values of the patients increased significantly at PSO compared to those measured at ESO., Conclusions: The results provide a basis for the development of psychological interventions that could minimize the prevalence of sleep disorders and depression and could improve patients' quality of life during the outbreak.

Objective: Facial diplegia (FD) is a rare neurological manifestation with diverse causes. This article aims to systematically evaluate the etiology, diagnostic evaluation and treatment of FD., Method: The study was performed retrospectively and included 17 patients with a diagnosis of FD., Results: Patients were diagnosed with Guillain-Barré syndrome (GBS) (11), Bickerstaff's brainstem encephalitis (1), neurosarcoidosis (1), non-Hodgkin's Lymphoma (1), tuberculous meningitis (1) herpes simplex reactivation (1) and idiopathic (1). In addition, two patients had developed FD during pregnancy., Conclusion: Facial diplegia is an ominous symptom with widely varying causes that requires careful investigation.

Unlabelled: P300 event-related potentials (ERPs), objective measures related to cognitive processing, have not been studied in Sydenham's chorea (SC) patients., Purpose: To assess cognitive impairment with P300 ERPs., Method: Seventeen patients with SC and 20 unaffected healthy children were included. Stanford-Binet test was used for psychometric assessment, and odd-ball paradigm was used for auditory ERPs., Results: There was no significant difference in P300 latencies between the SC-pretreatment group, SC-posttreatment group and control group (p>0.05). Mean interpeak latencies in SC-pretreatment group and SC-posttreatment group showed significant prolongation compared with the control group (p<0.05). Mean interpeak latencies in SC-posttreatment group were significantly decreased compared with SC-pretreatment group (p<0.05). Compared to controls, patients did not show significant difference in Stanford-Binet intelligence examination., Conclusion: This report suggests that interpeak latencies and amplitudes of P300 ERPs could be useful for detecting and monitoring cognitive impairment in SC patients.
