ObjectivePeripheral neuropathy (PN) is one of the most common diseases of the peripheral nervous system. Symptoms range from mild sensory signs to severe neuropathic pain. Untreated PN is progressive and can lead to complications and impair quality of life (QoL). However, PN prevalence is underestimated in the general population and affected individuals often remain undiagnosed. This study aimed to contribute to the global generation of prevalence data and determine sociodemographic and disease-related characteristics of PN sufferers.MethodsThis cross-sectional study collected information on PN prevalence and associated factors in the adult population (40-65 years) of the Mexico City area. Participants were recruited in public places and screened for PN using the Michigan Neuropathy Screening Instrument (MNSI). Subjects with PN answered the Neuropathy Total Symptom Score-6 (NTSS-6), the Short Form-36 Health Survey (SF-36), and the QoL Pharmacoeconomic Questionnaire. Statistical analysis included descriptive methods and calculation of PN prevalence with 95% confidence intervals.ResultsOf 3066 participants, 448 had PN based on the MNSI physical examination. The overall PN prevalence was 14.6%, with the highest (18.9%) seen in subjects aged 61-65 years. PN was undiagnosed in 82.6%, and 62.9% had never heard of PN. Although half of all subjects had only mild PN symptoms, QoL was impacted in 91.8%.ConclusionsThe results confirm that PN prevalence in the general population is high. Despite the disease burden, most affected persons are undiagnosed and unaware of the disease. Almost all felt their QoL was impacted. The data highlight the need to raise awareness and identify undiagnosed individuals to prevent complications.
