Mortality Attributed to Central and Peripheral Nervous System Disorders: A Five-years Comprehensive Review from Turkey

Objective: This study aims to provide a comprehensive overview of deaths related to central and peripheral nervous system (CNS and PNS, respectively) disorders in Turkey over a 5-year period. The objective is to identify patterns in mortality rates, investigate regional prevalence, and analyze demographic factors contributing to fatal outcomes. Additionally, we aim to critique existing data collection methodologies. Materials and Methods: Utilizing cross-sectional analysis, data were obtained from the Turkish Statistical Institute (TUIK). Mortality rates were calculated using population estimates from the TUIK, with age- and sex-specific rates, and age-standardized rates (ASRs) derived from the world standard population. Causes of death were classified according to the World Health Organization's International Classification of Diseases, Tenth Revision (ICD-10). Results: The data revealed distinct patterns in mortality rates for CNS and PNS disorders from 2018 to 2022, with significant variations between male and female populations. A prominent upward trend in deaths attributed to CNS and PNS diseases was observed after 2018, despite a decline in the population growth rate. The highest mortality rates were particularly notable in 2020 and 2021. Conclusion: This study identified a significant increase in deaths related to CNS and PNS disorders amid the backdrop of the COVID-19 pandemic. A potential correlation between COVID-19 and the prevalence of neurological disorders has been suggested. With potential underdiagnosis due to the absence of routine post-mortem diagnostic autopsies, this study underscores the need for improved diagnostic capabilities and medical practices.
