Aberrant protein processing with tissue deposition is associated with many common neurodegenerative disorders; however, the complex interplay of genetic and environmental factors has made it difficult to decipher the sequence of events linking protein aggregation with clinical disease. Substantial progress has been made toward understanding the(More)
We report on a new familial neurodegenerative disease with associated dementia that has presented clinically in the fifth decade, in both genders, and in each of several generations of a large family from New York State-a pattern of inheritance consistent with an autosomal dominant mode of transmission. A key pathological finding is the presence of neuronal(More)
BACKGROUND The aggregation of specific proteins is a common feature of the familial dementias, but whether the formation of neuronal inclusion bodies is a causative or incidental factor in the disease is not known. To clarify this issue, we investigated five families with typical neuroserpin inclusion bodies but with various neurological manifestations. (More)
OBJECTIVE To provide item analyses, estimates of temporal reliability and internal consistency, and examination of the sensitivity and specificity of a traumatic brain injury-screening tool. PARTICIPANTS Five hundred veterans of the wars in Iraq and Afghanistan enrolled in the study, approximately half of whom (248) volunteered. The remaining 252(More)
The Department of Veterans Affairs (VA) uses the Neurobehavioral Symptom Inventory (NSI) to measure postconcussive symptoms in its comprehensive traumatic brain injury (TBI) evaluation. This study examined the NSI's item properties, internal consistency, and external validity. Data were obtained from a federally funded study of the experiences of combat(More)
A number of studies have shown that HIV infection is associated with decreased olfactory ability. Additionally, it has been hypothesized that a reduced odorant identification may precede the advent of AIDS Dementia Complex (ADC). However, it is not known whether changes in olfactory ability are a manifestation of neurocognitive decline which may precede the(More)
BACKGROUND We recently discovered an autosomal dominant disease causing a progressive dementia. The disease is caused by a point mutation in the gene coding for the serine protease inhibitor (ie, serpin) neuroserpin. The mutation results in an unstable neuroserpin protein that readily aggregates into intraneuronal inclusions that we identify as Collins(More)
Few studies have measured combat exposure during deployment to a war zone. Valid, reliable, and specific measurement is needed to broaden existing knowledge of combat experiences to accurately answer clinically important questions regarding postcombat treatment and recovery, particularly with the recognition of new kinds of combat and resulting(More)
Traumatic brain injury (TBI) in Iraq and Afghanistan war veterans is frequently associated with a variety of complaints, including cognitive problems and posttraumatic stress disorder. In this study, the authors explored the predictive impact of premilitary cognitive abilities on postdeployment cognitive functioning, as mitigated by posttraumatic stress(More)
