- Introduction: Parkinson's disease (PD) is a neurodegenerative disease with motor and nonmotor symptoms. Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Objectives: To explore how COVID-19 affects motor, nonmotor, and general health aspects of PD and to map how PD patients perceive their change in symptoms since falling ill with COVID-19.Method: The study was descriptive, case-controlled, and based on both registry and questionnaire data. At baseline, the controls were matched on age, sex, and disease severity. Information on the severity of the disease, nonmotor symptoms, motor symptoms, and general health was retrieved from the Swedish Registry for PD. Registry data from a COVID-19 group (n=45) and a control group (n=73), as well as questionnaires from a COVID-19 group (n=24) and a control group (n=42), were compared.Results: We did not find that SARS-CoV-2 infection affects any major aspect of nonmotor symptoms, motor symptoms, general health, and perception of change in PD patients' post-COVID-19. Compared to controls, the COVID-19 group reported a more positive subjective experience of pain and quality of life and a perception of change post-COVID-19 regarding general motor function, sleep quality, and mood (all p<0.05).Conclusion: Although SARS-CoV-2 infection does not seem to affect PD symptoms in any major respect, the subjective experience of several aspects of life in PD patients might be slightly improved post-COVID-19 compared to a control group. The findings warrant further investigations due to the small sample size and possible survivorship bias.

- Objective: Oligoclonal bands (OBs) in electrophoresis of cerebrospinal fluid (CSF) are present in multiple sclerosis and here is investigated whether these also occur in experimental autoimmune encephalomyelitis (EAE). Material and methods: Experimental autoimmune encephalomyelitis was induced in 42 DA rats after immunization with rat spinal chord homogenate and the occurrence of OBs were detected by electrophoresis of both sera and CSF. The relationship between disease symptoms, antibody response against myelin basic protein (MBP), myelin oligodendrocyte glycoprotein (MOG) and appearance of OBs was studied. Results: Development of CSF-specific OB was found to occur, 6 weeks after immunization, in seven of 42 rats. OB was detected in rats with an antibody response against MBP, whereas as a role no such bands were present in rats with an antibody response against MOG. Initially severe disease symptoms were correlated to a concomitant intense oligoclonal antibody response. Conclusion: Cerebrospinal fluid-specific OB occurs in EAE. It is present in rats with an anti-MBP, but not in rats with an anti-MOG antibody response. A severe disease results in an intense oligoclonal antibody response, which might have an anti-inflammatory effect.

- OBJECTIVES: To report long-term effects of thalamic deep brain stimulation (DBS) on activities of daily living (ADL) and health-related quality of life (HRQoL) in patients with essential tremor (ET).MATERIALS AND METHODS: Nineteen consecutive patients were evaluated at baseline, at a mean of 1 year, then at a mean of 7 years after DBS using Tremor Rating Scale, Mini Mental Test, ADL Taxonomy, Nottingham Health Profile, Life Satisfaction Checklist, Visual Analogue Scale and interview.RESULTS: There was a decrease of DBS efficacy on tremor between 1 and 7 years post-operatively. The marked improvement in ADL at 1 year was no longer sustained at long-term, except for the ability to eat. Social life remained improved.CONCLUSION: Although there is a decrease of DBS effect on tremor at 7 years, and even though further ageing and co-morbidities may impact on the well-being of patients, there is still relevant benefit of DBS on few aspects of ADL and HRQoL in patients with ET.

- Objective Lateralized inattention is a typical sign of neglect and related to poor functional outcome. Knowledge of the long-term course of this phenomenon is limited. The purpose of this study was to investigate presence and predictors for signs of lateralized inattention 7 years after stroke. Methods From a cohort of acute ischemic stroke patients, aged 18-69 years (n = 297), a consecutive series of 188 survivors without recurrent stroke at follow-up 7 years later were included. Within the first week after stroke onset, stroke severity was assessed according to the Scandinavian Stroke Scale. Target omissions, asymmetry of omissions, and perceptual speed according to Star- and Letter Cancellation Tests were also assessed. Presence of lateralized inattention at the 7-year follow-up was investigated with the Star- and Letter Cancellation Tests and with the neglect item in the National Institutes of Health Stroke Scale. Results At the follow-up, 22 (11.7%) participants had lateralized inattention and the multivariable regression showed that independent significant baseline predictors were total omissions in target cancellations (P < .001) and inferior baseline performance on visual processing speed (P = .008). Conclusion About one of ten individuals exhibited signs of lateralized inattention 7 years after stroke. Baseline performance in perceptual processing speed and target omissions independently predicted presence of late signs of lateralized inattention. This is the first time processing speed is recognized as a significant predictor of lateralized inattention several years after the stroke incidence, indicating that the longitudinal course of processing speed following stroke is a critical subject for future research.

- A growing body of research highlights the importance of cognition for prediction of falls in Parkinson's disease (PD). However, a previously proposed prediction model for future near falls and falls in PD, which includes history of near falls, tandem gait, and retropulsion, was developed without considering cognitive impairment. Therefore, by using a sample of 64 individuals with relatively mild PD and not excluding those with impaired cognition we aimed to externally validate the previously proposed model as well as to explore the value of additional predictors that also consider cognitive impairment. Since this validation study failed to support the proposed model in a PD sample including individuals with impaired global cognition, extended analyses generated a new model including dyskinesia (item 32 of Unified PD Rating Scale) and frontal lobe impairment (Frontal Assessment Battery—FAB) as significant independent predictors for future near falls and falls in PD. The discriminant ability of this new model was acceptable (AUC, 0. 80; 95% CI 0.68-0.91). Replacing the continuous FAB scores by a dichotomized version of FAB with a cut-off score ≤14 yielded slightly lower but still acceptable discriminant ability (AUC, 0. 79; 95% CI 0.68-0.91). Further studies are needed to test our new model and the proposed cut-off score of FAB in additional samples. Taken together, our observations suggest potentially important additions to the evidence base for clinical fall prediction in PD with concomitant cognitive impairment.

- OBJECTIVES: To investigate the prevalence of visual neglect and its relationship to cognitive impairment and dementia in elderly stroke patients 20 months after stroke. METHODS: Of 243 stroke patients aged 70-91 years, 149 underwent neuropsychiatric testing, 138 with the Star Cancellation Test for visual neglect. RESULTS: Fifteen per cent (n = 21) had visual neglect, 9% (n = 12) severe and 9% (n = 12) lateralized. Cognitive impairments were twice as common in patients with neglect as in patients without it and threefold more common when the neglect was severe. Neglect was related to apraxia, impaired visual field, and a previous stroke. Severe neglect was related to dementia, amnesia and impaired visual field. CONCLUSIONS: Chronic neglect is common after stroke in elderly patients. So are cognitive impairments, especially in those with neglect. This calls for high alertness to impairments in spatial attention when treating patients with dementia and other cognitive impairments.

- Objective The purpose of the present study was to examine if there was a negative effect of caudal Zona Incerta deep brain stimulation (cZI DBS) on pharyngeal swallowing function in Parkinson’s patients (PD). There are no former reports on swallowing and cZI DBS.Methods Eight patients (aged 49 to 71 years; median 62) were evaluated pre- and postoperatively, at six and 12 months after DBS surgery. Evaluation tools were Fiberoptic Endoscopic Evaluation of Swallowing examinations and patients’ self-assessments of the swallowing function including a visual analogue scale and quality of life related questions. The swallowing protocol included Rosenbeck’s Penetration-Aspiration Scale, Secretion Severity Scale and parameters for pre-swallow spillage, pharyngeal residue and pharyngeal clearance.Results There was no clear-cut effect of neurostimulation postoperatively at six and 12 months on any of the swallowing parameters except for pre-swallow spillage which was slightly worsened in the stimulation on condition 12m postoperatively. The answers to the self assessment questions did not vary significantly.Conclusions The effect of the stimulation on swallowing function varied among individuals but the overall outcome was that cZI DBS did not seem to have a negative influence on swallowing function in the eight patients studied.

- ObjectivesWe compare various aspects in the early chain of care among patients with haemorrhagic stroke and ischaemic stroke. Materials & methodsThe Emergency Medical Services (EMS) and nine emergency hospitals, each with a stroke unit, were included. All patients hospitalised with a first and a final diagnosis of stroke between 15 December 2010 and 15 April 2011 were included. The primary endpoint was the system delay (from call to the EMS until diagnosis). Secondary endpoints were: (i) use of the EMS, (ii) delay from symptom onset until call to the EMS; (iii) priority at the dispatch centre; (iv) priority by the EMS; and (v) suspicion of stroke by the EMS nurse and physician on admission to hospital. ResultsOf 1336 patients, 172 (13%) had a haemorrhagic stroke. The delay from call to the EMS until diagnosis was significantly shorter in haemorrhagic stroke. The patient's decision time was significantly shorter in haemorrhagic stroke. The priority level at the dispatch centre did not differ between the two groups, whereas the EMS nurse gave a significantly higher priority to patients with haemorrhage. There was no significant difference between groups with regard to the suspicion of stroke either by the EMS nurse or by the physician on admission to hospital. ConclusionsPatients with a haemorrhagic stroke differed from other stroke patients with a more frequent and rapid activation of EMS.
