TASK-SPECIFIC METACOGNITIVE ACCURACY DECLINES ACROSS THE DEMENTIA-ALZHEIMER’S TYPE SPECTRUM.

Annalise M Rahman-Filipiak, Arijit Bhaumik, Bruno Giordani, Henry Paulson, Benjamin M Hampstead,

AbstractSubjective cognitive complaints (SCCs) remain part of the diagnostic criteria for amnestic mild cognitive impairment (aMCI), the prodromal stage of dementia - Alzheimer’s type (DAT), despite weak relationships between self-reported and objectively-measured functioning. Most metacognitive measures focus on ratings of global retrospective memory rating only; greater subtlety in measurement of ... Read more >>

Variable symptomatic and neurophysiologic response to HD-tDCS in a case series with posttraumatic stress disorder.

Benjamin M Hampstead, Nathan Mascaro, Stephen Schlaefflin, Arijit Bhaumik, Julia Laing, Scott Peltier, Brian Martis,

Chronic Posttraumatic stress disorder (PTSD), characterized by symptoms of re-experiencing, hyperarousal, and avoidance, is challenging to treat as a significant proportion of patients remain symptomatic following even empirically supported interventions. The current case series investigated the effects of up to 10 sessions of high definition transcranial direct current stimulation (HD-tDCS) ... Read more >>

The structural dynamics of the kinesin-2 stalk heterodimer and its biological relevance.

Zoheb Ahmed, Harinath Doodhi, Arijit Bhaumik, Shyamalava Mazumdar, Krishanu Ray,

Association between two motor subunits through the rod/stalk domain enables molecular motors to walk processively on protein filaments. Previous studies suggested that structural flexibility in the coiled-coil stalk of kinesins is essential for processive runs. The stalk of heterotrimeric kinesin-2, a comparatively less processive motor, is unstable at ambient temperature. ... Read more >>

Self- and Informant-Reported Memory Complaints: Frequency and Severity in Cognitively Intact Individuals and those with Mild Cognitive Impairment and Neurodegenerative Dementias.

Annalise M Rahman-Filipiak, Bruno Giordani, Judith Heidebrink, Arijit Bhaumik, Benjamin M Hampstead,

BACKGROUND:Subjective memory complaints (SMCs) are incorporated into the diagnosis of mild cognitive impairment (MCI) and neurodegenerative dementias; however, the relative frequency of SMCs in cognitively intact older adults and those with different types of dementia is poorly understood. Similarly, the concordance between self- versus informant-reported SMCs has not been compared ... Read more >>

Translational MRI Volumetry with NeuroQuant: Effects of Version and Normative Data on Relationships with Memory Performance in Healthy Older Adults and Patients with Mild Cognitive Impairment.

Julija Stelmokas, Lance Yassay, Bruno Giordani, Hiroko H Dodge, Ivo D Dinov, Arijit Bhaumik, K Sathian, Benjamin M Hampstead,

NeuroQuant (NQ) is a fully-automated program that overcomes several existing limitations in the clinical translation of MRI-derived volumetry. The current study characterized differences between the original (NQ1) and an updated NQ version (NQ2) by 1) replicating previously identified relationships between neuropsychological test performance and medial temporal lobe volumes, 2) evaluating ...

Prevalence of REM sleep behavior disorder in multiple system atrophy: a multicenter study and meta-analysis.

Jose-Alberto Palma, Clara Fernandez-Cordon, Elizabeth A Coon, Phillip A Low, Mitchell G Miglis, Safwan Jaradeh, Arijit K Bhaumik, Praveen Dayalu, Elena Urrestarazu, Jorge Iriarte, Italo Biaggioni, Horacio Kaufmann,

Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia frequently affecting patients with synucleinopathies, but its exact prevalence in multiple system atrophy (MSA) is unclear. Whether questionnaires alone are sufficient to diagnose RBD is also unknown.We performed a cross-sectional study of patients with probable MSA from six academic ... Read more >>

A large repertoire of gene-centric data has been generated in the field of zebrafish biology. Although the bulk of these data are available in the public domain, most of them are not readily accessible or available in nonstandard formats. One major challenge is to unify and integrate these widely scattered ... Read more >>

Can anchor models explain inverted-U effects in facial judgments?

Alain Mignault, Arijit Bhaumik, Avi Chaudhuri,

Researchers in a variety of disciplines have found that participants take less time and generate less diversity of responses when judging stimuli towards the ends of a scale than when judging those near the center. Three types of models, connectionist, exemplar, and anchor models, can account for these inverted-U effects. ... Read more >>

Caregiver support service needs for patients with mild cognitive impairment and Alzheimer disease.

Kelly A Ryan, Annie Weldon, Nicole M Huby, Carol Persad, Arijit K Bhaumik, Judith L Heidebrink, Nancy Barbas, Nancy Staffend, Lindsay Franti, Bruno Giordani,

Little is known about the service needs for persons caring for individuals with mild cognitive impairment (MCI). In this study, the level of support service need for caregivers of individuals diagnosed with Alzheimer disease (AD; N=55) and MCI (N=25) was compared with normal controls (N=44). Study partners (ie, caregivers) completed ... Read more >>
