Dementia is one of the fastest emerging global public health concerns today, as the World Health Organisation has predicted that the number of cases will triple from 55 million in 2023 to 152 million by 2050. Current evidence indicates that approximately 45% of dementia cases can be prevented or delayed by acting on potentially modifiable risk factors. However, public knowledge regarding this remains unknown in numerous poorly resourced countries, including Nepal, where the prevalence of dementia continues to increase.

Neuropsychiatric and neurodevelopmental disorders are complex conditions that arise from a variety of interacting genetic and environmental factors. Among these factors, altered serotonergic signalling and mitochondrial dysfunction are strongly implicated, with a growing body of evidence to suggesting that serotonergic signalling is an important regulator of mitochondrial biogenesis. The serotonin transporter (SERT) functions to regulate synaptic 5-HT, and human allelic variants of the serotonin reuptake transporter-linked polymorphic region (5-HTTLPR) are associated with reduced SERT expression and increased susceptibility for developing neuropsychiatric disorders.

Next generation brain health: transforming global research and public health to promote prevention of dementia and reduce its risk in young adult populations.

Lancet Healthy Longev

December 2024

Global Brain Health Institute (GBHI), Trinity College Dublin, Dublin, Ireland; Centre for Dementia Research, School of Health, Leeds Beckett University, Leeds, UK.

Efforts to prevent dementia can benefit from precision interventions delivered to the right population at the right time; that is, when the potential to reduce risk is the highest. Young adults (aged 18-39 years) are a neglected population in dementia research and policy making despite being highly exposed to several known modifiable risk factors. The risk and protective factors that have the biggest effect on dementia outcomes in young adulthood, and how these associations differ across regions and groups, still remain unclear.

Stressful life events and glucocorticoid (stress) hormones appear to increase the risk of Alzheimer's disease and hasten its progression, but the reasons for this remain unclear. One potential explanation is that when amyloid β (Aβ) pathology is accumulating in the preclinical disease stage, glucocorticoid receptor signalling during stressful events exacerbates cellular dysfunction caused by Aβ. Alternatively, Aβ may disrupt glucocorticoid receptor signalling.

From the day we are born, the nervous system is subject to insult, disease and degeneration. Aberrant phosphorylation states in neurofilaments, the major intermediate filaments of the neuronal cytoskeleton, accompany and mediate many pathological processes in degenerative disease. Neuronal damage, degeneration and death can release these internal components to the extracellular space and eventually the cerebrospinal fluid and blood.

Article Synopsis
  • CLN3 Batten disease is a lysosomal storage disorder characterized by retinal degeneration, seizures, motor decline, and early death, with defects in photoreceptor outer segment (POS) phagocytosis observed in patient-derived cells.
  • Researchers used CRISPR to create stem cell lines and a transgenic pig model to explore the effect of CLN3 mutations on POS phagocytosis.
  • Results showed that mutant RPE cells exhibit reduced POS uptake, leading to less efficient phagocytosis and subsequent loss of photoreceptor cells, indicating that both RPE dysfunction and mutant POS contribute to the disease's progression.

Article Synopsis
  • Chronic musculoskeletal pain frequently occurs alongside Parkinson's disease (PD), and this study aims to determine if chronic pain increases the risk of developing PD or other neurodegenerative disorders like multiple system atrophy (MSA) and progressive supranuclear palsy (PSP).
  • The research analyzed data from nearly 356,000 participants over a median of 13 years, identifying a clear link between the number of pain sites and the risk of developing PD: those with multiple pain locations had a significantly higher risk.
  • While chronic pain was notably associated with an increased risk of PD, there was no similar correlation found with MSA or PSP, suggesting that recognizing chronic pain could help identify individuals at risk for PD.

Vulnerability of neurofilament-expressing neurons in frontotemporal dementia.

Mol Cell Neurosci

December 2024

Wicking Dementia Research and Education Centre, University of Tasmania, Hobart, Tasmania, Australia.

Article Synopsis
  • Frontotemporal dementia (FTD) is a group of early-onset dementias caused by the degeneration of frontal and temporal brain lobes, leading to neuron loss, but specific vulnerabilities among different neuron types are not well understood.
  • This study investigates whether neurofilament-expressing neurons are particularly vulnerable in two types of FTD: FTLD-TDP and FTLD-Tau, by analyzing post-mortem brain tissue from affected individuals and controls.
  • The findings highlight a significant loss of neurofilament-expressing neurons in both FTD types compared to controls, suggesting these neurons are particularly susceptible to degeneration, while axonal neurofilament changes were found to be linked to age rather than FTD itself.

Dual decline in gait and cognition is associated with an increased risk of dementia, with combined gait and memory decline exhibiting the strongest association. To better understand the underlying pathology, we investigated the associations of baseline brain structure with dual decliners using three serial gait speed and cognitive assessments in memory, processing speed-attention, and verbal fluency. Participants (n=267) were categorized based on annual decline in gait speed and cognitive measures.

Neurons are central to lifelong learning and memory, but ageing disrupts their morphology and function, leading to cognitive decline. Although epigenetic mechanisms are known to play crucial roles in learning and memory, neuron-specific genome-wide epigenetic maps into old age remain scarce, often being limited to whole-brain homogenates and confounded by glial cells. Here, we mapped H3K4me3, H3K27ac, and H3K27me3 in mouse neurons across their lifespan.

The loss of upper and lower motor neurons, and their axons is central to the loss of motor function and death in amyotrophic lateral sclerosis (ALS). Due to the diverse range of genetic and environmental factors that contribute to the pathogenesis of ALS, there have been difficulties in developing effective therapies for ALS. One emerging dichotomy is that protection of the neuronal cell soma does not prevent axonal vulnerability and degeneration, suggesting the need for targeted therapeutics to prevent axon degeneration.
