Intracranial hypotension masquerading as nonconvulsive status epilepticus: report of 3 cases.

Intracranial hypotension (IH) has been a known entity in neurocritical care since 1938. Even though many cases are spontaneous, the incidence of intracranial hypotension in the neurocritical care setting is increasing by virtue of the increased number of neurosurgical interventions. Whether spontaneous or secondary in etiology, diagnosis of IH usually requires the presence of orthostatic symptoms, including headaches and nausea with low opening CSF pressure.

TBI surveillance using the common data elements for traumatic brain injury: a population study.

Background: To characterize the patterns of presentation of adults with head injury to the Emergency Department.

Methods: This is a cohort study that sought to collect injury and outcome variables with the goal of characterizing the very early natural history of traumatic brain injury in adults. This IRB-approved project was conducted in collaboration with our Institution's Center for Translational Science Institute.

Parkinsonism and neurological manifestations of influenza throughout the 20th and 21st centuries.

Purpose: Given the recent paper by Jang et al. on "A Highly Pathogenic H5N1 Influenza Virus" which reported a novel animal model of parkinsonism, we aimed to perform a complete historical review of the 20th and 21st century literature on parkinsonism and neurological manifestations of influenza.

Scope: There were at least twelve major flu pandemics reported in the literature in the 20th and 21st century.

Relative frequencies of Alzheimer disease, Lewy body, vascular and frontotemporal dementia, and hippocampal sclerosis in the State of Florida Brain Bank.

Alzheimer disease (AD) is the most common dementing illness in the elderly, but there is equivocal evidence regarding the frequency of other disorders such as Lewy body disease (LBD), vascular dementia (VaD), frontotemporal dementia (FTD), and hippocampal sclerosis (HS). This ambiguity may be related to factors such as the age and gender of subjects with dementia. Therefore, the objective of this study was to calculate the relative frequencies of AD, LBD, VaD, FTD, and HS among 382 subjects with dementia from the State of Florida Brain Bank and to study the effect of age and gender on these frequencies.
