Sleep problems in children.

Background: Childhood sleep problems are common, and frequently reduce the wellbeing and functioning of both child and family. The majority of childhood sleep problems are behavioural in origin.

Objective: This article outlines the aetiology and features of sleep difficulties in children, from infants to teenagers, and provides a corresponding 'toolkit' of evidence-based behavioural management strategies.

Caudate nucleus volume in individuals at ultra-high risk of psychosis: a cross-sectional magnetic resonance imaging study.

The aim of the present study was to investigate whether volumetric abnormalities of the caudate nuclei predate the onset of psychotic illness. Caudate nuclei volume (CNVs), excluding the tail, were measured using region-of-interest (ROI) tracing of magnetic resonance imaging (MRI) scans acquired on a 1.5T scanner.
