What are the relative merits of interventions used to reduce the occurrences of disruptive vocalisation in persons with dementia? - a systematic review.

Introduction: Dementia is a major health issue, and many people who have the progressive disease express disruptive vocalisation. These behaviours place large burdens on carers, family and on the individual themselves.

Background: This systematic review explored the use of interventions that could be used within practice to reduce the occurrences of disruptive vocalisation in people with dementia.

GAMMA simulations of stray field responses: slice thickness and pulse calibration.

A stray field (STRAFI) module has been added to the GAMMA magnetic resonance simulation platform in order to facilitate computational investigations of NMR experiments in large static field gradients that are on the order of 50 T/m. The package has been used to examine system response during echo trains generated by the application of shaped pulses. The associated echo amplitude maxima and effective slice thickness are presented.
