Research on epilepsies in 2012 has substantially advanced our knowledge of these often devastating conditions. From important discoveries that revealed causative factors and the molecular basis of disease, to major implications for surgical decision-making, these studies set the scene for future advances in the field.

Several clinical trials and experimental studies that could have a major impact on the treatment of patients with ischaemic stroke were published in 2012. The studies cover all therapeutic options, including stroke prevention, recanalization and thrombolysis, neuroprotection, and promising new therapeutic approaches focused on neurorepair.

Research in movement disorders in 2012 has improved our understanding of the pathogenic mechanisms of disease and led to development of potential novel therapeutic approaches. Key advances were linked to mechanisms underlying spread of neurodegenerative pathology, immunotherapy, stem cells, genetics and deep brain stimulation in parkinsonism and related disorders.

Transient amnesic syndromes, such as transient global amnesia and transient epileptic amnesia, are often difficult to diagnose. Recent studies, however, have examined the structural and functional underpinnings of these disorders. In this Review, Bartsch and Butler discuss how these studies have improved our understanding of transient amnesic syndromes, summarizing the key clinical aspects of different amnesic disorders and providing recommendations for diagnosis and patient management.

The ε4 allele of the apolipoprotein E (APOE) gene is the strongest genetic risk factor for Alzheimer disease (AD). Guojun Bu and colleagues describe the pathogenic links between Apo-E4 and neurodegeneration, including amyloid-β-dependent mechanisms and impairment of neurovascular function. The authors suggest potential strategies to target Apo-E, which could provide important additions to therapeutic options for AD.
