Although the interaction between comorbidities and chronic diseases is strong, the effect of comorbidities receives little attention in many chronic diseases. In multiple sclerosis (MS), an increasing amount of evidence suggests that physical and mental comorbidities, and adverse health factors such as smoking and obesity, are common and can affect the disease. These comorbid diseases and lifestyle factors affect clinical phenotype, the diagnostic delay between symptom onset and diagnosis, disability progression, and health-related quality of life. ⋯ Studies of the frequency of comorbidities in patients with MS should be population based, incorporating appropriate comparator groups. These studies should expand the range of comorbidities assessed, and examine how the frequency of comorbidities is changing over time. Further research is needed to answer many other questions about comorbidities and their associations with MS, including the best way to measure and analyse comorbidities to understand these associations.

Multiple sclerosis (MS) is a common, complex neurological disease. The precise aetiology of MS is not yet known, although epidemiological data indicate that both genetic and environmental factors are important. The evidence that the environment acts long before MS becomes clinically evident is well established and suggests the existence of a prodromal phase for the disease. ⋯ Studying a prodrome requires techniques other than clinical observation such as monitoring endophenotypes that result from associated risk factors. However, our current knowledge of causal pathways and endophenotypes in MS is limited. Identifying and studying individuals with a high risk of developing the disease provides a powerful opportunity to understand the MS causal cascade and is highly relevant to strategies that are aimed at preventing this debilitating disease.

Randomized Controlled Trial Multicenter Study
Methylprednisolone in combination with interferon beta-1a for relapsing-remitting multiple sclerosis (MECOMBIN study): a multicentre, double-blind, randomised, placebo-controlled, parallel-group trial.
Interferon beta is commonly used to treat patients with relapsing-remitting multiple sclerosis; however, the treatment is only partially effective in reducing relapses and progression of disability. Corticosteroids are used to treat relapses in patients with multiple sclerosis. We therefore aimed to investigate the combination of cyclic methylprednisolone and interferon beta for the treatment of relapsing-remitting multiple sclerosis. ⋯ Biogen Idec.

The term cerebral small vessel disease refers to a group of pathological processes with various aetiologies that affect the small arteries, arterioles, venules, and capillaries of the brain. Age-related and hypertension-related small vessel diseases and cerebral amyloid angiopathy are the most common forms. The consequences of small vessel disease on the brain parenchyma are mainly lesions located in the subcortical structures such as lacunar infarcts, white matter lesions, large haemorrhages, and microbleeds. ⋯ This classification, however, restricts the definition of small vessel disease to ischaemic lesions and might be misleading. Small vessel disease has an important role in cerebrovascular disease and is a leading cause of cognitive decline and functional loss in the elderly. Small vessel disease should be a main target for preventive and treatment strategies, but all types of presentation and complications should be taken into account.

Randomized Controlled Trial Clinical Trial
Lamotrigine for neuroprotection in secondary progressive multiple sclerosis: a randomised, double-blind, placebo-controlled, parallel-group trial.
Partial blockade of voltage-gated sodium channels is neuroprotective in experimental models of inflammatory demyelinating disease. In this phase 2 trial, we aimed to assess whether the sodium-channel blocker lamotrigine is also neuroprotective in patients with secondary progressive multiple sclerosis. ⋯ Multiple Sclerosis Society of Great Britain and Northern Ireland.
