Dissociating spatial and spatiotemporal aspects of navigation ability in chronic stroke patients.

Objective: The notion of distinguishable processing mechanisms for spatial and spatiotemporal information has largely been neglected in the context of navigation. Only a recent neuropsychological case study has provided initial evidence for the idea that these elements can be differentiated at a functional level. The aim of the current study was therefore to critically verify this double dissociation by adopting a systematic, large-scale approach.

Navigation strategy training using virtual reality in six chronic stroke patients: A novel and explorative approach to the rehabilitation of navigation impairment.

Recent studies have shown that navigation impairment is a common complaint after brain injury. Effective training programmes aiming to improve navigation ability in neurological patients are, however, scarce. The few reported programmes are merely focused on recalling specific routes rather than encouraging brain-damaged patients to use an alternative navigation strategy, applicable to any route.

Severe fatigue and reduced quality of life in children with hereditary motor and sensory neuropathy 1A.

Severe fatigue and low quality of life are reported by a majority of adult patients with hereditary motor and sensory neuropathy 1A. In children with hereditary motor and sensory neuropathy 1A, the prevalence and impact of fatigue have not been studied yet. In this questionnaire survey, 55 Dutch children (response rate 77%) with genetically confirmed hereditary motor and sensory neuropathy 1A participated (mean age 15 years [standard deviation 2.
