Importance The risk of developing Parkinson disease (PD) after objective hearing loss is unknown. PD studies using self-reported are insensitive, and data lacking. Objective To examine the association with incident in US veterans its effect modification by well-established prodromal conditions aids. Design, Setting, Participants This cohort study analyzed electronic health record from Department Veterans Affairs for who had an audiogram January 1, 1999, to December 30, 2022. Individuals missing or a preexisting diagnosis were excluded. Exposure Audiogram-confirmed loss. Main Outcomes Measures Cumulative incidence was calculated adjustment competing death.

Abstract Development of Parkinson’s Disease (PD) is linked with a history traumatic brain injury (TBI), although the mechanisms driving this remain unclear. Of note, many key parallels have been identified between pathologies PD and TBI; in particular, characterised by loss dopaminergic neurons from substantia nigra (SN), accompanied broader changes to signalling, disruption Locus Coeruleus (LC) noradrenergic system, accumulation aggregated α-synuclein Lewy Bodies, which spreads stereotypical pattern throughout brain. Widespread disruptions systems, including progressive neuronal SN LC, observed acutely following injury, some also chronically TBI patients preclinical models . Furthermore, expression are seen both brain, detailed characterisation these spread pathology limited. In review, we detail current literature regarding particular focus on how may predispose individuals prolonged neurodegeneration, particularly development PD. While it increasingly clear that risk factor for PD, significant gaps understanding neurodegenerative TBI, chronic manifestations injury.

The research criteria for prodromal Parkinson disease (pPD) depends on prospectively validated clinical inputs with large effect sizes and/or high prevalence. Neither traumatic brain injury (TBI), post-traumatic stress disorder (PTSD), nor chronic pain are currently included in the calculator, despite recent evidence of association pPD. These conditions widely prevalent, co-occurring, and already known to confer risk REM behavior (RBD) PD. Few studies have examined PD context TBI PTSD; none pain. This study aimed measure pPD caused by TBI, PTSD, 216 US Veterans were enrolled who had self-reported recurrent or persistent at least three months. Of these, 44 met 39 41 all conditions.

Abstract Background Electronic medical record (EMR)–based studies hold great potential for epidemiologic investigations of Parkinson's disease (PD) causal factors and phenomenology, but diagnostic misclassification may obscure or bias inferences. Objectives The aims were to determine the validity PD codes in Veterans Administration (VA) national electronic databases develop recommendations maximizing ascertainment accuracy. Methods We investigated a cohort 146,776 veterans who utilized VA healthcare between 1999 2021. reviewed records individuals with International Classification Diseases (ICD) code outpatient, inpatient, community care encounters assign gold‐standard diagnosis. determined accuracy based on provider type, coding frequency, medications, potentially exclusionary ICD overall by race. Results A total 377 810 (46.5%) had PD. whose was coded PD‐specialist neurologist most likely have (83.6%), sensitivity low (15.0%). Diagnostic decreased any (66.9%), improved (69.4%). Requiring two more combination levodopa prescriptions accuracy, particularly among nonneurologists. Neuroleptic‐induced parkinsonism frequent diagnosis those without (15.6%). Accuracy lower Black (29.0%) than White (50.5%) regardless type (miscoding odds ratio 2.5, 95% confidence interval 1.7–3.6). Conclusions These results highlight limitations EMR‐based ascertainment. Researchers can maximize considering specialty, pharmacy data, diagnoses, some degree review is required ensure high Higher miscoding warrants further study. © 2024 Author(s).

Background: Parkinson's disease (PD) is a heterogeneous with many non-motor manifestations that often precede motor symptom onset. While other sensory disturbances such as loss of sense smell or visual problems have been well-characterized, it unknown how hearing may influence PD incidence.Methods: We undertook large Electronic Health Record-based cohort study over 3 million US military Veterans objective audiogram data. Stratifying by severity, we determined cumulative incidence in each stratum. also analyzed this varied when combined several known comorbid conditions and receiving aid.Findings: Our major finding loss, defined pure tone audiometry, associated significant increased risk developing later life dose-dependent manner, worse more risk. Moreover, found synergized prodromal disorders constipation, resulting greater-than-additive incident they co-occurred. Additionally, report dispensing aid following an abnormal attenuated the observed PD. The Number Needed to Treat was estimated at 462 10 years after audiogram, striking effect given high prevalence low PD.Interpretation: Hearing appears be independent factor for development aids attenuate risk, therefore widespread screening appropriate use reduce PD.Funding: This work supported VA BLR&D CDA2 IK2 BX005760-01A1, John Tami Marick Family Foundation, Collins Medical Trust Award, OHSU MRF New Investigator PCO Pilot Award (to G.D.S.), CSR&D CX00253-01A1 L.E.N.).This National Center Rehabilitative Auditory Research (Center #C2361C/I50 RX002361) Disease Research, Education, Clinical Portland Care System. acknowledge assistance Oregon & Translational Institute, which through Grant UL1TR002369.Declaration Interest: declare no competing interests.Ethical Approval: Data were obtained from Administration under institution review board approval (MIRB #04744) using waiver participant consent.
