- We describe eight subjects from two consanguineous families segregating with autosomal recessive childhood onset spastic ataxia, peripheral neuropathy and intellectual disability. The degree of intellectual disability varied from mild to severe and all four affected individuals in one family developed aggressive behavior and epilepsy. Using exome sequencing, we identified two novel truncating mutations (c.2656C>T (p.Gln886*)) and (c.4756_4760delAATCA (p.Asn1586Tyrfs*3)) in the SACS gene responsible for autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). MRI revealed typical cerebellar and pontine changes associated with ARSACS as well as multiple supratentorial changes in both families as likely contributing factors to the cognitive symptoms. Intellectual disability and behavioral abnormalities have been reported in some cases of ARSACS but are not a part of the characteristic triad of symptoms that includes cerebellar ataxia, spasticity and peripheral neuropathy. Our combined findings bring further knowledge to the phenotypic spectrum, neurodegenerative changes and genetic variability associated with the SACS gene of clinical and diagnostic importance.

- BACKGROUND: Even though it is well known that disability due to MS is highly associated with employment status, the long-term longitudinal perspective on sickness absence and disability pension over the MS trajectory is lacking. In addition, further knowledge of risk factors for future disability pension is needed.OBJECTIVES: To explore long-term longitudinal changes in the prevalence of sickness absence and disability pension in people with MS (PwMS), as well as to explore associations between disease-specific factors, contextual factors and functioning, and the outcome of future full-time disability pension.METHODS: A prospective, population-based survival cohort study, with a nine year follow-up, including 114 PwMS was conducted by combining face-to-face collected data and register-based data.RESULTS: The prevalence of full-time disability pension increased from 20% to 50%, however 24% of the PwMS had no disability pension at all at end of follow-up. Sex, age, disease severity and impaired manual dexterity were associated with future full-time disability pension.CONCLUSIONS: The large increase in prevalence of PwMS on full-time disability pension during the MS trajectory, calls for the development and implementation of evidence-based interventions, aiming at keeping PwMS in the work force. Modifiable factors, such as manual dexterity should be targeted in such interventions.

- To evaluate coping strategies among patients with Amyotrophic lateral sclerosis starting with diagnosis and during the disease progression, as well as investigate changes and correlations between coping strategies, emotional well-being and physical function. A total of 36 patients participated in the study. The patients filled out the Hospital Anxiety and Depression Scale and the Motor Neuron Disease Coping Scale. Physical function was measured using the revised ALS functional rating scale. Data were collected regularly from diagnosis and over a two years period. As a way to cope with the disease patients relied on both problem focused and emotional focused strategies. The use of coping strategies remained stable. Both physical disabilities and emotional well-being was related to some coping strategies, with some variation during the disease progression. Moreover, some coping strategies were related to symptoms of anxiety and depression. Irrespective of whether the coping strategies affect the emotional well-being or vice versa, the results show the importance of early and continuous evaluation of coping and emotional well-being to ease the emotional distress and provide support to the patient so that he/she can cope with the disease during the disease progression.

- Objective: Aneurysmal subarachnoid hemorrhage (aSAH) is a common cause of long-term disability and death. After primary hemorrhage, secondary brain injury is the main cause of mortality and morbidity. Despite extensive research, reliable prognostic biomarkers are lacking. We measured ubiquitin carboxy-terminal hydrolase L1 (UCH-L1) levels in aSAH patients to evaluate its prognostic potential. This is the first time that plasma UCH-L1 has been studied as a potential prognostic biomarker in patients with aSAH. Methods: In this prospective population-based study, UCH-L1 levels were measured in aSAH patients (n = 47) for up to five days. UCH-L1 was measured at 0, 12 and 24 h after the admission to the intensive care unit (ICU) and daily thereafter until the patient was transferred from the ICU. Only patients whose UCH-L1 was measured within 24 h from aSAH were included in the study. The patients' neurological outcome was evaluated with the modified Rankin Scale (mRS) at six months after aSAH. Results: UCH-L1 levels during the first 24 h after aSAH were not significantly different between the groups with favorable (mRS 0-2) and unfavorable (mRS 3-6) neurological outcome. In 22 patients, UCH-L1 levels were obtained for up to five days. In this subgroup, UCH-L1 measured at day five showed significant elevation from baseline levels in patients with unfavorable outcome (p = 0.026). Elevated UCH-L1 levels at day five were higher in patients with unfavorable outcome than in patients with favorable outcome (p = 0.001). Conclusions: Elevated UCH-L1 levels during the five-day follow-up were associated with unfavorable neurological outcome. Repetitive measurements of UCH-L1 concentrations with an emphasis on change relative to the individual baseline could be the optimal approach for future clinical studies.
