1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Diabetes mellitus (DM) and neurological disorders are rapidly converging global health burdens, driven by population ageing, the growing prevalence of metabolic syndrome, and limited early detection and disease-modifying therapies for many neurological syndromes. Beyond its established role in diabetes-related peripheral neuropathy, DM is increasingly implicated as a modifier of risk, phenotype, and prognosis across a wide range of central and peripheral nervous system diseases. In this narrative review, we synthesize current epidemiological, clinical, genetic, and mechanistic evidence examining the relationship between DM and 10 clinically important neurological disorders: Alzheimer's disease (AD), vascular dementia (VaD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multiple sclerosis (MS), myasthenia gravis (MG), and neuromyelitis optica spectrum disorder (NMOSD). Across these conditions, DM acts as a context-dependent disease modifier, increasing risk in some disorders, appearing protective or delaying onset in others, and influencing disease phenotype, progression, and treatment response. We highlight potential areas of mechanistic convergence, such as insulin resistance, inflammation, disrupted energy homeostasis, and genetic predisposition, alongside important divergences shaped by disease-specific pathology. We also discuss the clinical and translational implications of this interface, including diagnostic challenges, opportunities for improved risk stratification, and growing interest in repurposing antidiabetic therapies, particularly metformin, glucagon-like peptide-1 receptor agonists, and sodium-glucose cotransporter-2 inhibitors, for neurological benefit. As the global burden of diabetes and neurological disease escalates, it is crucial to better understand the interplay between metabolic dysfunction, neurodegeneration, and neuro-immune pathways. The integration of insights across diseases may inform prevention strategies and support the development of therapeutic interventions at the metabolic-neurological interface.
