This paper concludes that findings suggest that 1) long-term omega-3 fatty acid supplementation may reduce risk of Alzheimer’s disease (AD); 2) dietary omega-3 fatty acid intake, especially DHA, may lower risk of dementia or cognitive decline; and 3) peripheral biomarkers of omega-3 fatty acids may serve as predictors of cognitive decline. However, further investigation is needed to understand the gene–environment interactions involved in the intake of omega-3 fatty acids.

This Viewpoint supports Sustainable Development Goal 3 by estimating the potential financial cost of lecanemab, a drug for early Alzheimer's disease, if it were to be approved in Europe at the same price as in the USA. The authors suggest that pricing would be unsustainable and that new payment models will be needed to address affordability and inequalities in access.

This Article supports Sustainable Development Goal 3 by highlighting differential effects of sleep disturbances on resting-state neural activity in patients on the Alzheimer's disease spectrum relative to healthy adults, suggesting a key role of sleep disturbances in the neurophysiological changes seen in Alzheimer's disease, with implications for basic research and clinical intervention.

This Article supports Sustainable Development Goal 3 by describing a cohort characterization model for Alzheimer’s Disease built on medications and diagnoses data that are widely available in a structured format in electronic health records (EHRs), showing that standard machine learning applied to sequences of EHR data can produce scalable computational characterization of Alzheimer’s disease cohorts.

This Article supports Sustainable Development Goal 3 by estimating the proportion of dementia attributable to hypertension, finding an overall global population attributable fraction of 15.8%. Results were also broken down by region and age. The authors note that the estimates from this study could help to inform public health policy at global and national levels.

This Comment article supports SDG 3 and 16 by highlighting how complex humanitarian settings have become fertile environments for spreading misinformation, disinformation, and malinformation, and how the 2021 release of the Oxford Statement on International Law Protection in Cyberspace, which touches on sovereignty, incitement, human rights, criminal law, general rules of international humanitarian law, and international criminal law, is an important first step to address this type of disinformation.

This News item supports SDG 3 by describing the work of the PAHO Commission on Mental Health and COVID-19, which was created in order to improve mental health care in the Latin America and Caribbean region in light of the mental health crisis resulting from the pandemic. The article describes the 10 recommendations set forth by the Commission, and the opportunities and implications of these recommendations.

This Review supports SDG 3 by assessing the availablility of data for reporting elimination targets of mother-to-child transmission of HIV, hepatitis B, and syphilis, and reports on progress towards these targets in Pacific Island countries and territories.

This review supports SDG 3 as despite available antiviral therapy, hepatitis C virus (HCV) remains a global health burden and a prophylactic vaccine would help to eliminate the risk to develop chronic liver diseases. This paper uses data to draw a simplified model of virus entry, which highlights gaps in our current knowledge that warrant further research to fully understand this process at the atomic level.

This Article supports SDG 3 by evaluating shared-care models with hepatitis B virus testing in China, including an analysis of the cost-effectiveness and the impact on quality of life and mortality.
