#1
Meneka Kaur Sidhu, John S Duncan, Josemir W Sander
PURPOSE OF REVIEW: Epilepsy neuroimaging is important for detecting the seizure onset zone, predicting and preventing deficits from surgery and illuminating mechanisms of epileptogenesis. An aspiration is to integrate imaging and genetic biomarkers to enable personalized epilepsy treatments. RECENT FINDINGS: The ability to detect lesions, particularly focal cortical dysplasia and hippocampal sclerosis, is increased using ultra high-field imaging and postprocessing techniques such as automated volumetry, T2 relaxometry, voxel-based morphometry and surface-based techniques...

Jennifer L Whitwell
PURPOSE OF REVIEW: The aim of this study was to discuss the contribution of neuroimaging studies to our understanding of Alzheimer's disease. We now have the capability of measuring both tau and beta-amyloid (Aβ) proteins in the brain, which together with more traditional neuroimaging modalities, has led the field to focus on using neuroimaging to better characterize disease mechanisms underlying Alzheimer's disease. RECENT FINDINGS: Studies have utilized tau and Aβ PET, as well as [18F]fluorodeoxyglucose PET, and structural and functional MRI, to investigate the following topics: phenotypic variability in Alzheimer's disease , including how neuroimaging findings are related to clinical phenotype and age; multimodality analyses to investigate the relationships between different neuroimaging modalities and what that teaches us about disease mechanisms; disease staging by assessing neuroimaging changes in the very earliest phases of the disease in cognitively normal individuals and individuals carrying an autosomal dominant Alzheimer's disease mutation; and influence of other comorbidities and proteins to the disease process...

PURPOSE OF REVIEW: We focus on new insights in the pathophysiology of Parkinson's disease tremor, essential tremor, tremor in dystonia, and orthostatic tremor. RECENT FINDINGS: Neuroimaging findings suggest that Parkinson's disease resting tremor is associated with dopaminergic dysfunction, serotonergic dysfunction, or both. Not all tremors in Parkinson's disease have the same pathophysiology: postural tremor in Parkinson's disease can be subdivided into pure postural tremor, which involves nondopaminergic mechanisms, and re-emergent tremor, which has a dopaminergic basis...

#5
Irene H Flønes, Charalampos Tzoulis
PURPOSE OF REVIEW: The scope of this review is to give an updated account of movement disorders associated with mitochondrial disease, with a particular focus on recently discovered clinicopathological correlations. RECENT FINDINGS: Movement disorders are common clinical manifestations of mitochondrial diseases, in part because of the high vulnerability of neurons controlling motor circuits to mitochondrial respiratory dysfunction and energy failure. Intriguingly, the clinicopathological correlations of movement disorders in mitochondrial disease do not always conform to established neurophysiological knowledge...

Peter Bede, Giorgia Querin, Pierre-François Pradat
PURPOSE OF REVIEW: Neuroimaging in motor neuron disease (MND) has traditionally been seen as an academic tool with limited direct relevance to individualized patient care. This has changed radically in recent years as computational imaging has emerged as a viable clinical tool with true biomarker potential. This transition is not only fuelled by technological advances but also by important conceptual developments. RECENT FINDINGS: The natural history of MND is now evaluated by presymptomatic, postmortem and multi-timepoint longitudinal imaging studies...

Massimo Filippi, Federica Agosta
PURPOSE OF REVIEW: The correct classification of non-Alzheimer's dementia is crucial to study disease mechanisms, predict disease progression and test disease-specific treatments. Brain atrophy assessment with morphometric MRI is currently the gold standard for in-vivo localization of neurodegeneration. Structural and functional connectivity biomarkers are becoming increasingly available. This review emphasizes the potential applications of MRI in the main non-Alzheimer's dementia such as dementia with Lewy bodies (DLB) and frontotemporal dementia (FTD)...
