Diffusion-weighted imaging changes in cerebral watershed distribution following neonatal encephalopathy are not invariably associated with an adverse outcome.
Patterns of injury in term-born infants with neonatal encephalopathy following hypoxia-ischaemia are seen earlier and are more conspicuous on diffusion-weighted magnetic resonance imaging (DW-MRI) than on conventional imaging. Although the prognostic value of DW-MRI in infants with basal ganglia and thalamic damage has been established, data in infants in whom there is extensive injury in a watershed distribution are limited. The aim of this study was to assess cognitive and functional motor outcome in a cohort of infants with changes in a predominantly watershed distribution injury on neonatal cerebral MRI, including DWI. ⋯ Extensive DWI changes in a watershed distribution in term-born neonates are not invariably associated with adverse sequelae, even in the presence of cystic evolution. Associated lesions of the basal ganglia and thalami are a better predictor of adverse sequelae than the extent and severity of the watershed abnormalities seen on DW-MRI.

Characteristics of post-traumatic headaches in children following mild traumatic brain injury and their response to treatment: a prospective cohort.
Post-traumatic headaches (PTHs) following mild traumatic brain injury (mTBI) are common; however, few studies have examined the characteristics of PTHs or their response to treatment. The aims of this study were (1) to describe the clinical characteristics of PTH in a prospective cohort of children presenting to a paediatric emergency department with mTBI, and (2) to evaluate the response of PTH to treatment. ⋯ This is the first prospective cohort study to describe the clinical characteristics of PTHs following mTBI in children. Migraine was the most common headache type seen; other headaches included tension-type, cervicogenic, and occipital neuralgias, and 64% responded to treatment. Referral to a headache specialist should be considered, especially when the features are not typical of one of the primary headache disorders.
