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.

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.

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 Multicenter Study Meta Analysis
Deep brain stimulation plus best medical therapy versus best medical therapy alone for advanced Parkinson's disease (PD SURG trial): a randomised, open-label trial.
Surgical intervention for advanced Parkinson's disease is an option if medical therapy fails to control symptoms adequately. We aimed to assess whether surgery and best medical therapy improved self-reported quality of life more than best medical therapy alone in patients with advanced Parkinson's disease. ⋯ At 1 year, surgery and best medical therapy improved patient self-reported quality of life more than best medical therapy alone in patients with advanced Parkinson's disease. These differences are clinically meaningful, but surgery is not without risk and targeting of patients most likely to benefit might be warranted.
