Nervous System Diseases

The grounding supports a broad, multifactorial aetiology rather than a single cause. Literature is indexed to genetic, epigenetic, metabolic, inflammatory, infectious, and toxic mechanisms, and to specific processes such as oxidative stress, aging, and brain-gut axis-related influences. Some reviews also link nervous system disease to SARS-CoV-2 infection and to ferroptosis-related cell death.

The literature describes several overlapping biological processes, including altered signal transduction, neuronal plasticity, oxidative stress, and ferroptosis. Co-studied mediators include cytokines, autoantibodies, amyloid beta-peptides, neurofilament proteins, microRNAs, long noncoding RNA, circular RNA, and receptor- and kinase-related pathways. Neurofilament light chain is highlighted as a marker of axonal damage across inflammatory, neurodegenerative, traumatic, and cerebrovascular disorders.

Supported risk factors or associated influences include aging, genetic factors, oxidative stress-related biology, and disturbances of the gastrointestinal microbiome and brain-gut axis. The grounding also supports association with SARS-CoV-2 infection and with inflammatory or autoimmune processes reflected by cytokines and autoantibodies. No single universal risk factor is supported for all nervous system diseases.

Treatment is heterogeneous and depends on the specific nervous system disorder. The grounding supports therapy and drug therapy at a broad level, including biologic and immunologic approaches in some contexts, but does not provide enough detail to specify standard modalities for the category as a whole. Diagnostic imaging and biomarker-based monitoring are also covered in the literature.
