Brain injury; Brain lesions; Disease burden; Lesion load; Volume loss; White matter lesions, WML
Lesion burden, a phrase sometimes used interchangeably with lesion load, is a term that may be similar to the idea in medicine of disease burden but in the neuroimaging literature often refers to the overall cumulative effect or burden of brain lesions identified by magnetic resonance imaging (MRI).
Lesion burden has been studied extensively in the field of multiple sclerosis (MS) and typically refers to white matter lesions (WML). Studies in MS may analyze both T1- and T2-weighted MRI identified lesion burden, for example, as well as concomitant brain volume, as they are associated with clinical outcomes such as health-related quality of life (Mowry et al. 2009), cognitive dysfunction (Patti et al. 2015), and even fatigue (Tedeschi et al. 2009, 2007). The idea of lesion burden or load has also been used with other populations such as stroke in terms...
