Several studies indicate that, in individuals infected with herpes simplex virus and/or varicella zoster virus, antiviral therapy reduces the subsequent risk of Alzheimer disease and other types of dementia. As highlighted in this article, the preventative potential of antiviral therapy would probably be maximized by treating asymptomatic as well as symptomatic infected individuals.
A recent clinical trial found no effect of chronic intranasal oxytocin on social behaviour in children with autism spectrum disorders. The result is not surprising, as oxytocin facilitates social learning but does not directly cause prosocial behaviour. In future trials, oxytocin should be paired with behavioural therapy to enhance learning and improve social behaviour.
Rare neurological complications can occur after COVID-19 vaccination, but recent studies show that such complications are much more common after SARS-CoV-2 infection. Novel approaches to risk–benefit analysis such as Bayesian network models can integrate the latest global evidence with local factors to inform decision-making and support the global vaccination effort.
In this Review, the authors consider how current understanding of four genetic generalized epilepsy syndromes that commonly occur in adults challenges traditional concepts about these conditions and suggests that they are not distinct but sit on a neurobiological continuum.
In this Review, the authors give an overview of the genetics of common small vessel disease, and provide insights into causal genes and the biological pathways involved, the overlap with monogenic small vessel disease, and the therapeutic implications of these factors.
Here, the authors summarize the evidence concerning the neurological health of individuals affected by the 11 September 2001 terrorist attacks and present the outcome of a meeting convened by the US National Institute for Occupational Safety and Health that aimed to generate recommendations for future research in this population.
Traditionally, CNS diseases have been classified into early-onset neurodevelopmental disorders and late-onset neurodegenerative disorders. However, as this article highlights, we now recognize that developmental and neurodegenerative disorders can involve shared mechanisms, with some classic neurodegenerative diseases also having a neurodevelopmental component.
