Neuroepidemiology

To describe the epidemiology of spinal cord injury (SCI) in the developing world. ⋯ Through an understanding of the epidemiology of SCI in developing countries, appropriate preventative strategies and resource allocation may decrease the incidence and improve the care of these injuries.

Atrial fibrillation (AF) is a major risk factor for stroke, especially in the elderly. Increased life expectancies mean that AF-related stroke is a growing global public health concern. Improvements in the detection, treatment and prevention of the consequences of AF have occurred in recent years. ⋯ Evidence on changes in the prevalence of AF, the risk of stroke associated with AF and the excess cost of AF-related stroke over the last 30 years was summarised. The results provide evidence that the age-adjusted prevalence of AF and the relative risk of stroke associated with AF has remained relatively constant. Unless action is taken to improve detection of AF and reduce its consequences, a considerable increase in the social and economic burden associated with AF-related stroke is likely.

Meta Analysis
Prevalence of traumatic brain injury in the general adult population: a meta-analysis.
Traumatic brain injury (TBI) is a significant public-health concern. To understand the extent of TBI, it is important to assess the prevalence of TBI in the general population. However, the prevalence of TBI in the general population can be difficult to measure because of differing definitions of TBI, differing TBI severity levels, and underreporting of sport-related TBI. ⋯ Across 15 studies, all originating from developed countries, which included 25,134 adults, 12% had a history of TBI. Men had more than twice the odds of having had a TBI than did women, suggesting that male gender is a risk factor for TBI. The adverse behavioral, cognitive and psychiatric effects associated with TBI coupled with the high prevalence of TBI identified in this study indicate that TBI is a considerable public and personal-health problem.

The clinical diagnosis of Parkinson's disease (PD) is proposed to be too late for the application of beneficial neuroprotective treatment. Thus, it is important to identify and follow individuals at risk for PD in order to gain knowledge about the prodromal course of the disease. Substantia nigra hyperechogenicity (SN+) has been confirmed as a risk factor for PD and appears promising as a predictor of PD, particularly in combination with other putative PD markers. We present the design and initial data of a 2-year longitudinal investigation of subjects proposed to be at high risk of developing PD (HRPD), compared to early PD patients and control subjects. The aim of the presented study is to monitor progression of the neurodegenerative process to motor PD. ⋯ Here, we describe the recruitment of a highly enriched-risk cohort and a promising study design to assess progression to motor PD. Whether the HRPD group indeed suffers from early, PD-specific neurodegeneration remains to be verified in the ongoing follow-up examinations.

Severity of acute vascular illness may have changed in the last decades due to improvements in primary and secondary prevention. Population-based data on the severity of acute ischemic cerebrovascular disease are sparse. We aimed to examine incidence, characteristics and severity of acute ischemic cerebrovascular disease in a well-defined population. ⋯ Minor events are the most common in ischemic cerebrovascular disease, and may constitute a larger proportion than previously reported. TIA and stroke patients share many characteristics; however, TIA patients are younger and have fewer manifestations of atherosclerotic diseases, indicating a high potential for secondary prevention.
