Donepezil and memantine have similar modest clinical and spectroscopic effect on mild to moderate AD. MRS could be useful to monitor progression of the disease.
BackgroundAdherence to interferon β-1b (INFβ-1b) therapy is essential to maximize the beneficial effects of treatment in multiple sclerosis (MS). For that reason, the main objectives of this study are to assess adherence to INFβ-1b in patients suffering from MS in Spain, and to identify the factors responsible for adherence in routine clinical practice.Methodology/Principal FindingsThis was an observational, retrospective, cross-sectional study including 120 Spanish patients with MS under INFβ-1b treatment. Therapeutic adherence was assessed with Morisky-Green test and with the percentage of doses received. The proportion of adherent patients assessed by Morisky-Green test was 68.3%, being indicative of poor adherence. Nevertheless, the percentage of doses received, which was based on the number of injected medication, was 94.3%. The main reason for missing INFβ-1b injections was forgetting some of the administrations (64%). Therefore, interventions that diminish forgetfulness might have a positive effect in the proportion of adherent patients and in the percentage of doses received. In addition, age and comorbidities had a significant effect in the number of doses injected per month, and should be considered in the management of adherence in MS patients.Conclusion/SignificanceAmong all the available methods for assessing adherence, the overall consumption of the intended dose has to be considered when addressing adherence.
The aim of this work was to investigate the efficacy of the GABAergic drug gabapentin in the treatment of the cerebellar signs caused by cortical cerebellar atrophy (CCA). Ten patients with CCA received gabapentin in single doses of 400 mg in an open-label study; thereafter, daily administration of 900–1,600 mg of gabapentin was continued during at least 4 weeks. An ataxia scale based on clinical findings was used to evaluate the cerebellar signs at baseline and after administration of the drug. A statistically significant improvement of the ataxia scores was found after single doses of 400 mg of gabapentin and after the administration of 900–1,600 mg of this drug during 4 weeks, as compared to the results obtained at baseline. An important clinical amelioration was also evident. Gabapentin has been demonstrated to be capable of improving the cerebellar signs in cases of CCA, after single doses and after continued administration of the drug during 4 weeks. GABAergic enhancement or supplementation could play an important role in the treatment of diseases of the cerebellar cortex associated with a deficit of GABA.
There have been few reports about the frequency of multiple sclerosis (MS) in Spain. We undertook a prevalence study in the province of Teruel, which is served by two hospitals as referral centres for a population of 143,680. We found a total of 46 patients who fulfilled Poser's criteria for clinically definite or probable MS with a prevalence rate of 32/100,000 [95% confidence interval (CI): 22.8-41.3]. The prevalence rates for males and females were 23.5 (95% CI: 12.3-34.7) and 40.6 (95% CI: 25.8-55.4) respectively. We found an incidence rate of 2.2/year per 100,000 in the last 5 years. The sex ratio (females/males) was 1.7. The mean age on prevalence day was 40.6 years (range: 15-76). The clinical course was relapsing-remitting in 82% of patients, progressive in 9% and secondary progressive in the other 9%. The mean EDSS score was 3.73 (range: 1-8.5). Our results confirm the hypothesis that Spain is an area at high risk for MS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
