ABSTRACT
Introduction
Metabolomics is an emerging approach providing new insights into the metabolic changes and underlying mechanisms involved in the pathogenesis of neurological disorders.
Areas covered
Here, the authors present an overview of the current knowledge of metabolic profiling (metabolomics) to provide critical insight on the role of biochemical markers and metabolic alterations in neurological diseases.
Expert opinion
Elucidation of characteristic metabolic alterations in neurological disorders is crucial for a better understanding of their pathogenesis, and for identifying potential biomarkers and drug targets. Nevertheless, discrepancies in diagnostic criteria, sample handling protocols, and analytical methods still affect the generalizability of current study results.
Article highlights
Metabolomics is an emerging approach providing new insights into individual metabolic profile.
The investigation of characteristic metabolic alterations in neurological disorders is crucial for a better understanding of their pathogenesis.
Metabolomics markers hold the potential of improving diagnosis, follow-up of patients, and clinical trial outcomes.
Discrepancies in the phenotyping/classification of the neurological diseases and their subtypes, the mixed cohorts of patients and uncontrolled sampling conditions, have, to date, prevented identification of clear metabolic profiles and pathways.
