Among the 40 million people with epilepsy worldwide, 80% reside in low-income regions where human and technological resources for care are extremely limited. Qualitative and experiential reports indicate that people with epilepsy in Africa are also disadvantaged socially and economically, but few quantitative systematic data are available. We sought to assess the social and economic effect of living with epilepsy in sub-Saharan Africa. ⋯ People with epilepsy in Zambia have substantially poorer social and economic status than do their peers with non-stigmatised chronic medical conditions. Suboptimum housing quality differentially exposes these individuals to the risk of burns and drowning during a seizure. Vulnerability to physical violence is extreme, especially for women with epilepsy.

Meningiomas account for up to 30% of all primary intracranial tumours. They are histologically classified according to the World Health Organization (WHO) classification of tumours of the nervous system. ⋯ With increase in tumour grade, additional progression-associated molecular aberrations can be found; however, most of the relevant genes are yet to be identified. High-throughput techniques of global genome and transcriptome analyses and new meningioma models provide increasing insight into meningioma biology and will help to identify common pathogenic pathways that may be targeted by new therapeutic approaches.

Caring for elderly people with dementia is associated with well-documented increases in burden, distress, and decrements in mental health and wellbeing. More severe behavioural, cognitive, and functional impairments in a patient are associated with higher levels of burden and distress. Distress increases with care hours per week, number of tasks, and declining coping and support resources. ⋯ Promising, evidence-based interventions exist, but substantial economic and policy barriers preclude their widespread dissemination. Health-care policy makers should consider addressing these barriers; clinicians and families must campaign for reimbursement; and clinical researchers must develop more potent preventive interventions. In this article we review how dementia care affects the mental health of the carer and identify interventions that might be useful in mitigating carer burden and distress.

Comparative Study
Lack of replication of thirteen single-nucleotide polymorphisms implicated in Parkinson's disease: a large-scale international study.
A genome-wide association study identified 13 single-nucleotide polymorphisms (SNPs) significantly associated with Parkinson's disease. Small-scale replication studies were largely non-confirmatory, but a meta-analysis that included data from the original study could not exclude all SNP associations, leaving relevance of several markers uncertain. ⋯ Our results do not lend support to the finding that the 13 SNPs reported in the original genome-wide association study are genetic susceptibility factors for Parkinson's disease.
