Summary: This study examined cognitive trajectories in late life using two independent datasets and identified four similar trajectories in the decade before death. Factors associated with declining trajectories included death age, Braak neurofibrillary tangles stage, TDP-43, and alpha-synuclein. Multiple pathologies were most common in trajectories with cognitive decline.

Summary: According to Alzheimer's Disease International, there are 55 million people worldwide living with dementia, which is a set of symptoms resulting from brain damage. The symptoms involve progressive impairments in memory, thinking, and behavior, often accompanied by emotional problems, language difficulties, and decreased motivation. Although attempts to treat dementia by addressing symptoms have failed, this narrative review aims to explain the etiology of dementia and Alzheimer's disease through the perspective of energy and cognitive metabolism dysfunction in an aging brain.

Summary: This study found that individuals with high blood pressure exhibited impaired performance in domains such as immediate and delayed word recall, animal naming, number series, and numeracy tasks. Clinicians should incorporate these tasks into the neuropsychological assessment of individuals with high blood pressure and explore strategies to improve their cognitive performance.

Summary: As people age, they often face cognitive deterioration, which can develop into dementia. The presence of neuropathological signs does not always accurately reflect the degree of clinical symptoms. The concept of reserve capacity suggests that the brain has the ability to buffer changes associated with aging and cope with damage. Prenatal and early postnatal factors shape the reserve capacity of the brain and cognitive reserve. The early environment can influence the risk of neurodegenerative diseases by programming the reserve capacity.

Summary: This study aimed to provide a more accessible way to detect sarcopenia by comparing the traditional method of DXA lean mass estimation versus the tongue and masseter muscle mass assessed in a standard brain MRI. The results showed a significant correlation between tongue and masseter muscle mass with DXA lean mass, and the prevalence of sarcopenia calculated using head muscles did not differ from sarcopenia calculated using DXA. Almost all participants were correctly classified using both methods.

Summary: By studying the effects of manipulating the olfactory bulb and its cortex efferents, researchers found that reducing gamma oscillations in the limbic areas of the brain can induce depression-like behaviors in rodents. However, enhancing gamma oscillations can alleviate these behaviors. The findings suggest that restoring gamma oscillations may be a potential treatment for depressive symptoms.

Summary: This study reveals a genetic overlap and causal relationship between primary open-angle glaucoma (POAG) and neurodegenerative disorders, but does not find strong evidence of a causal association between these traits. It also identifies some genetic overlaps and shared risk loci, suggesting a potential shared genetic risk between glaucoma and neurodegenerative disorders. Despite some similarities at the genetic level, the neurodegenerative process of glaucoma appears to be distinct from that of neurodegenerative diseases.

Summary: Alzheimer's disease (AD) is a concern for the aging population and prevention is a key focus due to the lack of cure or reliable treatments. Various dietary patterns, including the Mediterranean, DASH, MIND, ketogenic, and modified Mediterranean-ketogenic diets, have been studied for their preventive effects on AD and related dementia. Plant-based dietary patterns have consistently shown positive correlation with preventing and reducing the odds of ADRD. These patterns not only directly impact the brain but also indirectly reduce the effects of risk factors through decreasing diabetes, obesity, and cardiovascular diseases. Psychosocial factors, such as social connection, also play a role in dietary intake and ADRD risk.

Summary: A standardized blood collection device combined with an automated elution system was used to test illegal gold miners in French Guiana for HIV, HBV, HCV, and syphilis. The results showed that the Ser-Col method allows automated dried blood testing with performances comparable to dried blood spot sampling. This method facilitates large-scale surveys and improves testing in remote areas.

Summary: Psychiatric disorders are prevalent brain pathologies. Reliable animal models are needed for effective treatment. Zebrafish show complex behaviors similar to rodents and humans, making them suitable for modeling psychiatric disorders. However, there are challenges and the field needs further discussion and consideration of clinical prevalence and pathological complexity. Recent developments in molecular biology might pave the way for wider use of zebrafish in CNS disease modeling.

Summary: Depression and schizophrenia are common and debilitating neuropsychiatric disorders, for which current pharmacotherapies have limited efficacy and significant side effects. This highlights the need for novel drug targets. Recent advancements in translational research, research tools, and approaches have provided potential avenues for innovative drug discovery. This article provides a comprehensive overview of current treatments and outlines potential molecular targets for these disorders, while also addressing translational challenges and unanswered questions to encourage further research.

Summary: Epilepsy is a neurological disorder characterized by seizures and neuronal hyperactivity. The exact pathogenesis is not fully understood, but genetic factors are known to play a key role. In this study, a computational approach was used to generate a comprehensive network of molecular pathways associated with epilepsy. The study identified potential key interactors and revealed functional molecular pathways, highlighting the importance of targeting downstream pathways for more effective treatments.

Summary: This study investigated the behavioral effects of GBR 12909, a selective dopamine transporter (DAT) blocker, in zebrafish. The results showed that acute treatment with GBR 12909 resulted in hypolocomotion, anxiety-like state, and impaired spatial cognition in zebrafish. These behavioral effects are similar to those observed in DAT knockout rodents and zebrafish, as well as other DAT-inhibiting drugs of abuse such as cocaine and D-amphetamine.

Summary: Music therapy has positive effects on improving cognitive function and mood in humans and animals. This study examines the impact of solfeggio-frequency music exposure on behavior, cognition, and endocrine parameters in adult zebrafish that were subjected to a disturbance in circadian rhythm. It was found that continuous exposure to music for 24 hours or intermittent exposure for 2 or 6 hours twice daily reversed the cognitive deficits and elevated cortisol levels caused by 24-hour light exposure. These findings highlight the positive modulation of cognitive and endocrine responses in adult zebrafish through long-term music exposure.

Summary: The link between bio-metals, Alzheimer's disease, and A beta protein is very complex, and copper plays a crucial role in amyloid-beta toxicity and AD development. High levels of copper accumulation in the AD brain result in modulation of toxic A beta peptide levels, and the interaction between copper and A beta contributes to the pathophysiology of AD.

Summary: Previous studies on error processing have primarily focused on the posterior medial frontal cortex, but the role of other brain regions has been underestimated. This study used activation likelihood estimation meta-analyses to explore brain activity related to committing errors and responding successfully in interference tasks. It was found that the salience network and the temporoparietal junction were commonly involved in both correct and incorrect responses, indicating their general involvement in coping with situations that require increased cognitive control. Error-specific convergence was observed in the dorsal posterior cingulate cortex, posterior thalamus, and left superior frontal gyrus, while successful responding showed stronger convergence in the dorsal attention network and lateral prefrontal regions. Underrecruitment of these regions in error trials may reflect failures in activating the appropriate stimulus-response contingencies necessary for successful response execution.
