New guidelines for designing controlled clinical trials for idiopathic intracranial hypertension (IIH) have been published. The design of such trials remains a challenge, as the heterogeneity of IIH necessitates different outcome measures for specific clinical presentations.
The limited success of amyloid-β-targeting therapies for Alzheimer disease has led to a shift in focus towards the tau protein. This Review provides an update on the initial trials of tau-targeting therapies, focusing particularly on immunotherapies, and considers future directions for these therapies.
The underlying cause of sporadic Alzheimer disease (AD) remains enigmatic, but an increased risk among spouses of people with AD has led to speculation of transmissibility. A mouse study now suggests that the transfer of microbiota could underlie this potential transmissibility, but the findings leave many questions unanswered.
Understanding of the pathogenetic mechanisms underlying cerebral malaria remains incomplete despite intense scrutiny. Hadjilaou et al. discuss potential treatment strategies targeting pathogen replication and clearance, host–pathogen interactions at the cerebrovasculature or leveraging host innate and adaptive immunity.
The term amyotrophic lateral sclerosis (ALS)–frontotemporal spectrum disorder encompasses a spectrum ranging from pure motor ALS to ALS with frontotemporal dementia. This Review focuses on the cognitive and behavioural impairments that are found in the mid-range of this spectrum.
Acquired neurocognitive impairment affects 30–50% of the 38 million people living with HIV worldwide. Here, the authors provide an overview of the proposed mechanisms of HIV-associated neurocognitive impairment and describe potential and emerging therapeutics and non-pharmacological interventions.
Here, the authors discuss evidence for the involvement of the cerebellum in Parkinson disease. They cover the anatomical connections between the cerebellum and basal ganglia and how functional and connectivity alterations observed in the cerebellum of people with the disease relate to specific clinical symptoms.
Researchers in China and South Korea have developed a rapid immunodot assay to detect aquaporin 4-targeting IgG autoantibodies in the serum of individuals with neuromyelitis optica spectrum disorder.
A new study indicates that although men and women are equally likely to experience cognitive impairment after acute ischaemic stroke, there are sex differences in particular cognitive domains. Whether these differences are directly linked to biological sex is uncertain, as many factors, including age and pre-stroke factors, could contribute to cognitive outcomes.
The amyotrophic lateral sclerosis exposome is the lifetime accumulation of environmental exposures that increase disease risk and affect progression. This Review summarizes the literature that has sought to characterize aspects of the amyotrophic lateral sclerosis exposome and considers potential mechanisms of exposure-induced toxicity.
The TRACK-TBI LONG study has shown that outcomes are highly variable in the 7 years after traumatic brain injury (TBI). Although many patients remain stable, almost one-third experience declines in cognitive, psychiatric and functional state. These findings suggest that TBI is a chronic disease and that its management should change accordingly.
