Traumatic brain injury (TBI) is identified as a risk factor for Parkinson's disease (PD), which is a neurodegenerative disease characterized by the loss of dopaminergic neurons in the substantia nigra (SN). However, the precise mechanism by which chronic TBI initiates PD pathogenesis is not yet fully understood. In our present study, we assessed the chronic progression and pathogenesis of PD-like behavior at different intervals in TBI mice.

The ADNI is detailed in Supplemental Acknowledgments.
Background: α-Synuclein (α-Syn) pathology is present in 30-50 % of Alzheimer's disease (AD) patients, and its interactions with tau proteins may further exacerbate pathological changes in AD. However, the specific role of different aggregation forms of α-Syn in the progression of AD remains unclear.
Objectives: To explore the relationship between various aggregation types of CSF α-Syn and Alzheimer's disease progression.

Parkinson's disease (PD) is characterized by a slow, short-stepping, shuffling gait pattern caused by a combination of motor control limitations due to a reduction in dopaminergic neurons. Gait disorders are indicators of global health, cognitive status, and risk of falls and increase with disease progression. Therefore, the use of quantitative information on the gait mechanisms of PD patients is a promising approach, particularly for monitoring gait disorders and potentially informing therapeutic interventions, though it is not yet a well-established tool for early diagnosis or direct assessment of disease progression.

Parkinson's disease (PD) is one of the most prevalent neurodegenerative disorders among older adults, yet its long-term impact on mortality within population-based cohorts remains insufficiently characterized. This study leverages data from the Neurological Disorders in Central Spain (NEDICES) cohort to provide a comprehensive 23-year mortality analysis in a Spanish population. In this prospective cohort study, 5278 individuals aged 65 years and older were evaluated across two waves: baseline (1994-1995) and follow-up (1997-1998).

: Inflammation is reportedly related to Parkinson's disease (PD). However, the relationship between the systemic immune-inflammation index (SII) and PD remains unexplored. This study aimed to explore the potential relationship between the SII and PD.
