This lecture intends to highlight an important diagnostic challenge for clinicians, namely DPN, along with clinical insights for enabling its accurate diagnosis. Complications w.r.t delayed diagnosis of DPN and vital screening tools like Semmes-Weinstein monofilament examination, tuning fork test, ankle reflex and questionnaires like MNSI, TSS etc. are elaborately discussed. Important diagnostics like QST, sudomotor function testing, NCS, skin punch biopsy and corneal confocal microscopy are also discussed.
