Sleep disorders are a relatively common occurrence after brain injury. Sleep disturbances often result in a poor daytime performance and a poor individual sense of well-being. Unfortunately, there has been minimal attention paid to this common and often disabling sequela of brain injury. This study attempts to define and to correlate the incidence and type(More)
Prospective studies establish cognitive status as an important determinant of post-stroke rehabilitation success. The Neurobehavioral Cognitive Status Examination (NCSE) briefly assesses cognition in the ability areas of language, constructions, memory, calculation and reasoning. The NCSE, as well as the commonly used Mini-Mental State Examination and(More)
Communicating normal pressure hydrocephalus (NPH) is an important remote complication of traumatic brain injury (TBI). The diagnosis of this hydrocephalus depends largely on clinical signs and symptoms, including cognitive deterioration, gait changes and incontinence. However, many of these signs are also seen during post-traumatic amnesia, making early(More)
We have observed five individuals who appear to represent a unique subgroup of patients with traumatic brain injury (TBI). Because of the prominence of severe ataxia, this group has been labelled the 'ataxic subgroup'. These individuals are distinguished by both clinical course and outcome, including severe ataxia, prolonged coma and prolonged(More)
Transcranial magnetic stimulation has generated extensive interest within the traumatic brain injury (TBI) rehabilitation community, but little work has been done with repetitive protocols, which can produce prolonged changes in behavior. This is partly because of concerns about the safety of repetitive transcranial magnetic stimulation (rTMS) in subjects(More)
The impact of a traumatic brain injury on the family of the injured person is just beginning to be explored. In the current study, 61 primary caregivers were contacted at 1 year following injury. They completed the Relative and Friend Support Index, Social Support Index, Trauma Complaints List and the Life Change Question. The majority of caregivers(More)
During the early phases of recovery from traumatic head injury, the level of functional cognition and the presence of agitation in patients appear to co-vary. However, it has been observed that there appears to be some temporal disassociation in the recovery of cognition and agitation. The purpose of this study was to investigate the degree to which(More)
The case of a traumatic brain injury (TBI) patient with dramatic cognitive deterioration in the absence of medical aetiology other than simultaneous decline in serum sodium led to an investigation of the association between declines in sodium levels and cognitive status. In a population of 50 persons undergoing TBI rehabilitation, 12 (24%) had relative (3(More)
Posttraumatic agitation is perhaps the most dramatic behavioral consequence of severe traumatic brain injury. The mechanism for this behavior remains to be determined. The development of effective management strategies has been hampered at least in part by the lack of a consensus definition for posttraumatic agitation. The diagnosis of posttraumatic(More)
The F-response is a valuable tool for evaluating the functional integrity of proximal nerve segments. Although many studies have focused on the various F-response characteristics observed (e.g., latency, amplitude, duration, persistence, etc.), few have examined the significance of stimulus parameters on the resultant F-response. In this study, we examined(More)
