Mansur, Roger C. Ho, Joshua D. Rosenblat, Kamilla W. Miskowiak, Maj Vinberg, Vladimir Maletic, Roger S. McIntyre

Summary: Post-COVID-19 syndrome, characterized by persistent symptoms after resolution of acute infection, is associated with significant fatigue and cognitive impairment. This study aimed to quantify the proportion of individuals experiencing fatigue and cognitive impairment 12 or more weeks after COVID-19 diagnosis, and to explore the inflammatory and functional consequences of post-COVID-19 syndrome. The results showed that a significant proportion of individuals continue to experience fatigue and cognitive impairment even after 12 or more weeks of COVID-19 diagnosis. Additionally, some individuals showed elevated levels of inflammatory markers and significant functional impairment.

Summary: Microglial research has made significant progress, but the current classification system fails to accurately describe their diversity, leading to misconceptions about their functions. To address this issue, a group of multidisciplinary experts has proposed a naming framework and recommendations to help researchers better understand and describe the different states and functions of microglia.

The generalizability crisis

Tal Yarkoni

Summary: Most theories and hypotheses in psychology are verbal in nature, yet their evaluation overwhelmingly relies on inferential statistical procedures. However, many applications of statistical inference in psychology fail to meet the basic condition of closely aligning verbal and statistical expressions, which results in limited generalizability of results, increased false-positive rates, and researchers drawing sweeping verbal generalizations without meaningful connection to statistical quantities.

The role of prefrontal cortex in cognitive control and executive function

Naomi P. Friedman, Trevor W. Robbins

Summary: Concepts of cognitive control and executive function are defined in relation to goal-directed behavior versus habits, controlled versus automatic processing, and the functions of the prefrontal cortex and related regions and networks. There is unity and diversity in cognitive control constructs, including general cognitive control and components specific to mental set shifting and working memory updating. The relationships of cognitive control with psychopathology, impulsivity, genetic studies, and psychiatric classification are also explored.

The serotonin theory of depression: a systematic umbrella review of the evidence

Summary: The serotonin hypothesis of depression, which suggests that depression is caused by lowered serotonin activity or concentrations, lacks consistent evidence based on the synthesis and evaluation of research in this field. This umbrella review found no substantial association between serotonin and depression, while suggesting that long-term antidepressant use may reduce serotonin concentration.

Summary: Neurological and neuropsychiatric symptoms that persist or develop three months after the onset of COVID-19 pose a significant threat to the global healthcare system. A systematic review analyzed data from multiple studies and found that fatigue, cognitive dysfunction, and sleep disturbances were key features of post-COVID-19 syndrome. Psychiatric manifestations such as anxiety and depression were also common and increased in prevalence over time.

Summary: Alzheimer's disease is a global health crisis, and there are numerous clinical trials and drugs in development to treat and improve the symptoms and progression of the disease. The pipeline of drug development includes a diverse array of treatments, including disease-modifying therapies, cognitive enhancing treatments, and drugs for neuropsychiatric symptoms. Advances in drug design, outcome measures, biomarker use, and trial conduct show promise in accelerating the delivery of new and improved treatments for Alzheimer's disease patients.

The probabilistic model of Alzheimer disease: the amyloid hypothesis revised

Giovanni B. Frisoni, Daniele Altomare, Dietmar Rudolf Thal, Federica Ribaldi, Rik van der Kant, Rik Ossenkoppele, Kaj Blennow, Jeffrey Cummings, Cornelia van Duijn, Peter M. Nilsson, Pierre-Yves Dietrich, Philip Scheltens, Bruno Dubois

Summary: The amyloid hypothesis has long been the leading model for the pathogenesis of Alzheimer's disease, but a probabilistic model is proposed as an alternative due to the increasing understanding of the complex biology of Alzheimer's disease. This new model suggests that genetic factors, environmental exposures, and lower-risk genes play significant roles in different types of Alzheimer's disease, leading to a better understanding of disease pathophysiology and potentially accelerating the development of prevention and treatment strategies.

Summary: This study reveals unique autophagy dysregulation within neurons in Alzheimer's disease mouse models, particularly deficient autolysosome acidification, leading to the accumulation of autophagic vacuoles and the formation of flower-like structures called "PANTHOS," which may contribute to the development of senile plaques in Alzheimer's disease.

SARS-CoV-2 Infectivity and Neurological Targets in the Brain

Walter J. Lukiw, Aileen Pogue, James M. Hill

Summary: The novel coronavirus SARS-CoV-2 enters human host cells through the ACE2 receptor, allowing it to attack multiple cell types simultaneously and cause harm to various tissues and organ systems. This study found that ACE2 is highly expressed not only in respiratory, digestive, renal-excretory, and reproductive cells, but also in regions of the brain such as the amygdala, cerebral cortex, and brainstem. The high expression of ACE2 in the brainstem, particularly in the respiratory centers, may explain the susceptibility of COVID-19 patients to severe respiratory distress.

Pathological mechanisms and therapeutic strategies for Alzheimer's disease

Yaojun Ju, Kin Yip Tam

Summary: Alzheimer's disease is a complex neurodegenerative disease characterized by synaptic dysfunctions and neurotransmitter deficiencies. The pathological features of Alzheimer's disease include changes in β-amyloid and tau proteins. Aging and other factors are also risk factors for the disease. Therefore, developing treatment strategies that target different pathological factors is crucial.

The past, present and future of Registered Reports

Christopher D. Chambers, Loukia Tzavella

Summary: Registered Reports were introduced a decade ago to improve the rigour and credibility of confirmatory research by peer reviewing study proposals before research is undertaken. While they are not a universal solution for irreproducibility, early evidence suggests that Registered Reports are working as intended and are promoting reproducibility, transparency, and self-correction across disciplines. The policies and practices surrounding Registered Reports are evolving to address limitations and adapt to new challenges.
