OBJECTIVE: FDG PET/MRI examination of the body is routinely performed from the skull base to the mid thigh. Many types of brain abnormalities potentially could be detected on PET/MRI if the head was included. The objective of this study was therefore to identify and characterize brain findings incidentally detected on PET/MRI of the body with the head included. MATERIALS AND METHODS: We retrospectively identified 269 patients with FDG PET/MRI whole-body scans that included the head...

Prenatal exposure to maternal stress and depression has been identified as a risk factor for adverse behavioral and neurodevelopmental outcomes in early childhood. However, the molecular mechanisms through which maternal psychopathology shapes offspring development remain poorly understood. We applied transcriptome-wide screens to 149 umbilical cord blood samples from neonates born to mothers with posttraumatic stress disorder (PTSD; n=20), depression (n=31) and PTSD with comorbid depression (n=13), compared to carefully matched trauma exposed controls (n=23) and healthy mothers (n=62)...

The neuropsychiatric examination includes standard neurological and cognitive examination techniques with several additional observations and tasks designed to capture abnormalities common among patients with neuropsychiatric disorders or neurocognitive complaints. Although useful as a screening tool, a single standardized rating scale such as the Mini Mental State Examination (MMSE) or the Montreal Cognitive Assessment (MoCA) is insufficient to establish a neuropsychiatric diagnosis. Extra attention is paid to findings commonly seen in the setting of psychiatric disorders, dementias, movement disorders, or dysfunction of cortical or subcortical structures...

BACKGROUND: Dystonia-deafness syndrome is a well-known clinical entity, with sensorineural deafness typically manifesting earlier than dystonia. ACTB p.Arg183Trp heterozygosity has been reported in six patients to cause combined infant-onset deafness and dystonia manifesting in adolescence or young adulthood. Three of these have received beneficial pallidal stimulation. Brain imaging to assess striatal function has not been reported previously, however. Nor has a comprehensive hypothesis been presented for how the pleiotropic manifestations of this specific beta-actin gene mutation originate developmentally...

BACKGROUND/AIMS: The utility of β-site amyloid-β precursor protein (AβPP) cleaving enzyme 1 (BACE1) activity and soluble AβPP β (sAβPPβ) levels in cerebrospinal fluid (CSF) in detecting Alzheimer's disease (AD) is still elusive. METHODS: BACE1 activity and sAβPPβ concentration were measured in patients with AD dementia (n = 56) and mild cognitive impairment (MCI) due to AD (n = 76) with abnormal routine AD CSF markers, in patients with MCI with normal CSF markers (n = 39), and in controls without preclinical AD (n = 48)...

Neurodevelopmental outcomes are impaired in survivors of critical congenital heart disease (CHD) in several developmental domains including motor, cognitive and sensory outcomes. These deficits can extend into the adolescent and early adulthood years. The cause of these neurodevelopmental impairments is multi-factorial and includes patient specific risk factors, cardiac anatomy and physiology as well as brain changes seen on MRI. Advances in imaging techniques have identified delayed brain development in the neonate with critical CHD as well as acquired brain injury...

In addition to the role of planning and executing movement, the cerebellum greatly contributes to cognitive process. Numerous studies have reported structural and functional abnormalities in the cerebellum for HIV-infected patients, but little is known about the altered functional connectivity of particular cerebellar subregions and the cerebrum. Therefore, this study aimed to explore the resting-state functional connectivity (rsFC) changes of the cerebellum and further analyze the relationship between the rsFC changes and the neuropsychological evaluation...

Copper (Cu) plays key roles in catalytic and regulatory biochemical reactions essential for normal growth, development, and health. Dietary Cu deficiencies or mutations in Cu homeostasis genes can lead to abnormal musculoskeletal development, cognitive disorders, and poor growth. In yeast and mammals, Cu is acquired through the activities of the Ctr1 family of high-affinity Cu transporters. However, the mechanisms of systemic responses to dietary or tissue-specific Cu deficiency remain unclear. Here, taking advantage of the animal model Caenorhabditis elegans for studying whole-body Cu homeostasis, we investigated the role of a C...

 The aberrant accumulation of the amyloid protein is a critical and early event in the Alzheimer's disease (AD) cascade. Given the early involvement of this pathological process, it is not surprising that many clinically normal (CN) older individuals demonstrate evidence of abnormal Aβ at postmortem examination and in vivo using either CSF or PET imaging. Converging evidence across multiple research groups suggests that the presence of abnormal Aβ among CN individuals is associated with elevated risk of future clinical impairment and cognitive decline...

Individuals with schizophrenia demonstrate broad impairments in neurocognitive functioning as measured through laboratory-based tasks. Neuropsychological measures depend on rapid instruction-based task learning (RITL), the ability to rapidly translate task instruction into goal-directed behavior. Here, the authors present the first known investigation of RITL in schizophrenia and aim to test whether RITL deficits exist in schizophrenia, are associated with abnormal brain activation, and contribute to the generalized cognitive deficit...

BACKGROUND: Emerging evidence suggests that children with fragile X syndrome (FXS) exhibit abnormal gesture use early in development, although few studies have investigated the emergence of gesture use in this population or the impact of autism spectrum disorder (ASD) features on these behaviours. The present study examined the longitudinal development of gesture use in infants with FXS relative to low-risk controls and infant siblings of children with ASD (high-risk siblings), with the goal of establishing potentially unique patterns of gesture development in infants with FXS and understanding the relative impact of ASD symptom severity on these patterns...

Introduction: Medial temporal lobe (MTL) uptake on tau-positron emission tomography (PET) is seen not only in Alzheimer's disease (AD) dementia but also in the aging population. The relationship of these findings to the development of AD dementia needs to be better understood. Methods: Tau-PET with AV-1451 was performed on 576 cognitively unimpaired (CU) participants aged 50-94 years. The number of CUs with and without abnormal MTL regions and those with or without extra-MTL abnormalities was determined...

This is a 10-year follow-up study of a family with ferroportin disease A. The proband, a 59-year-old man showed no noteworthy findings with the exception of an abnormal iron level. The proband's 90-year-old father showed reduced abilities in gait and cognition; however, with the exception of his iron level, his biochemistry results were almost normal. Brain imaging showed age-matched atrophy and iron deposition. In both patients, the serum levels of ferritin and hepcidin25, and liver CT scores declined over a 10-year period...

Inability to accurately diagnose Lewy type alpha-synucleinopathy (LTS) pre-mortem has been a major obstacle to clinical care and research. Probable REM sleep behavior disorder (PRBD) diagnosed with support of instruments such as the Mayo Sleep Questionnaire (MSQ) may provide a cost effective means of predicting LTS. Since 2007, 602 subjects in the Arizona Study of Aging and Neurodegenerative Disorders had clinician assessment for PRBD (298 with, 304 without support of the MSQ), completed cognitive and movement examinations, and had neuropathological assessment...
