The B cell-depleting IgG1 monoclonal antibody rituximab can persistently suppress disease progression in some patients with autoimmune diseases. However, the mechanism underlying these long-term beneficial effects has remained unclear. Here, we evaluated Ig gene usage in patients with anti-myelin-associated glycoprotein (anti-MAG) neuropathy, an autoimmune disease of the peripheral nervous system that is mediated by IgM autoantibodies binding to MAG antigen. Patients with anti-MAG neuropathy showed substantial clonal expansions of blood IgM memory B cells that recognized MAG antigen. The group of patients showing no clinical improvement after rituximab therapy were distinguished from clinical responders by a higher load of clonal …

Cosmetic Neurology: Enhancement Of The Mind And Attention Deficit Hyperactive Disorder Medication Abuse Among College Students, Mary M. Huff Apr 2012

Cosmetic Neurology: Enhancement Of The Mind And Attention Deficit Hyperactive Disorder Medication Abuse Among College Students, Mary M. Huff

Senior Honors Theses

Cosmetic neurology is becoming increasingly popular, and it is not just sleep deprived, over worked college students who are interested. People are beginning to seek off-label prescriptions for medications that are typically used to treat disorders such as attention deficit hyperactive disorder (ADHD) or narcolepsy, while researchers are trying to create drugs used solely for mind enhancement purposes. Along with these drugs come many legal and ethical quandaries relating to the regulation of current use as well as the what ifs of future possibilities. A survey was conducted among college students regarding the diagnosis of ADHD, the abuse of ADHD …

Section of Neurology

Environmental manganese (Mn) toxicity causes an extrapyramidal, parkinsonian-type movement disorder with characteristic magnetic resonance images of Mn accumulation in the basal ganglia. We have recently reported a suspected autosomal recessively inherited syndrome of hepatic cirrhosis, dystonia, polycythemia, and hypermanganesemia in cases without environmental Mn exposure. Whole-genome mapping of two consanguineous families identified SLC30A10 as the affected gene in this inherited type of hypermanganesemia. This gene was subsequently sequenced in eight families, and homozygous sequence changes were identified in all affected individuals. The function of the wild-type protein and the effect of sequence changes were studied in the manganese-sensitive yeast strain …

Old Remedies For Epilepsy: Avicenna's Medicine., A A Asadi-Pooya, A R Nikseresht, E Yaghoubi

Department of Neurology Faculty Papers

BACKGROUND: The history of epilepsy and its treatments dates back to at least 4 millennia. Avicenna, c. 980 AD in Bukhara, Khorasan-1037 in Hamedan was a Persian-speaking Iranian physician, who has many recommendations and suggested various therapies for epilepsy in his book, The Canon of Medicine.

METHODS: We first reviewed the most important ancient treatments for epilepsy mentioned by Avicenna and considered those as the key words for our next step. Then, we made a literature search (medline and scopus) with those key words to find out new scientific findings in modern medicine about the Avicenna's suggestions.

RESULTS: Among the …

Massicotte, Stephen Lewis, Raja Rampersaud

Department of Neurosurgery Faculty Papers

Background: There is convincing preclinical evidence that early decompression in the setting of spinal cord injury (SCI) improves neurologic outcomes. However, the effect of early surgical decompression in patients with acute SCI remains uncertain. Our objective was to evaluate the relative effectiveness of early (,24 hours after injury) versus late ($24 hours after injury) decompressive surgery after traumatic cervical SCI.

Methods: We performed a multicenter, international, prospective cohort study (Surgical Timing in Acute Spinal Cord Injury Study: STASCIS) in adults aged 16–80 with cervical SCI. Enrolment occurred between 2002 and 2009 at 6 North American centers. The primary outcome was …

College of Population Health Lectures, Presentations, Workshops

Background:

• Neuroimaging is a diagnostic tool that may be used to rule out a serious condition when a patient presents with head pain. It is not typically warranted for patients who have a normal neurologic exam, and may be over utilized despite established practice parameters set by the American Academy of Neurology.

•A decision to use neuroimaging should consider the type of headache and presence of any clinical features that suggest a serious condition.

Over-utilization of neuroimaging has cost and safety implications.

The United States Headache Consortium, a panel of experts on migraine, set the guidelines for diagnosis and …

College of Population Health Lectures, Presentations, Workshops

Background

Safety concerns exist when using triptansto treat patients with cardiac contraindications.

–Triptans cause vasoconstriction, a safety concern for migraineurswith cardiovascular (CV) disease or other cardiac risk factors.

–All triptans contain contraindications in their package inserts to avoid use in patients with cardiac conditions.

•Previous research indicates that clinicians are less likely to prescribe triptansin patients with CV disease or CV risk factors.

Limited research has examined the proportion of migraine patients with cardiovascular disease or those individuals who were concurrently treated with triptans.

Surgical Outcome In Pet-Positive, Mri-Negative Patients With Temporal Lobe Epilepsy, Carla Lopinto-Khoury, Michael R. Sperling, Christopher Skidmore, Maromi Nei, James Evans, Ashwini Sharan, Scott Mintzer

Department of Neurology Faculty Papers

PURPOSE:

Fluorodeoxyglucose positron emission computed tomography (FDG-PET) hypometabolism is important for surgical planning in patients with temporal lobe epilepsy (TLE), but its significance remains unclear in patients who do not have evidence of mesial temporal sclerosis (MTS) on magnetic resonance imaging (MRI). We examined surgical outcomes in a group of PET-positive, MRI-negative patients and compared them with those of patients with MTS.

METHODS:

We queried the Thomas Jefferson University Surgical Epilepsy Database for patients who underwent anterior temporal lobectomy (ATL) from 1991 to 2009 and who had unilateral temporal PET hypometabolism without an epileptogenic lesion on MRI (PET+/MRI-). We compared …

Purging Of Memories From Conscious Awareness Tracked In The Human Brain, Benjamin Levy, Michael C. Anderson Jan 2012

Purging Of Memories From Conscious Awareness Tracked In The Human Brain, Benjamin Levy, Michael C. Anderson

Psychology

Understanding the neural basis of conscious experience and its regulation are fundamental goals of science. While recent research has made substantial progress in identifying the neural correlates of conscious experiences, it remains unclear how individuals exert control over the contents of awareness. In particular, can a memory that has entered the aware state be purged from consciousness if it is not currently desired? Here we tracked the correlates of consciousness in humans using functional magnetic resonance imaging and demonstrated the involvement of a downregulation mechanism that purges contents from conscious awareness. When individuals tried to prevent the retrieval of a …


Ensembles Of Human Mtl Neurons "Jump Back In Time" In Response To A Repeated Stimulus, M. W. Howard, Indre Viskontas, K. H. Shankar, I. Fried Jan 2012

Ensembles Of Human Mtl Neurons "Jump Back In Time" In Response To A Repeated Stimulus, M. W. Howard, Indre Viskontas, K. H. Shankar, I. Fried

Psychology

Episodic memory, which depends critically on the integrity of the medial temporal lobe (MTL), has been described as ‘‘mental time travel’’ in which the rememberer ‘‘jumps back in time.’’ The neural mechanism underlying this ability remains elusive. Mathematical and computational models of performance in episodic memory tasks provide a specific hypothesis regarding the computation that supports such a jump back in time. The models suggest that a representation of temporal context, a representation that changes gradually over macroscopic periods of time, is the cue for episodic recall. According to these models, a jump back in time corresponds to a stimulus …

Manifestations Of Rheumatoid Arthritis: Epidural Pannus And Atlantoaxial Subluxation Resulting In Basilar Invagination., Adam L Schreiber, Do, Ma Jan 2012

Manifestations Of Rheumatoid Arthritis: Epidural Pannus And Atlantoaxial Subluxation Resulting In Basilar Invagination., Adam L Schreiber, Do, Ma

Department of Rehabilitation Medicine Faculty Papers

Presented in part at the AAPMR 71st Annual Assembly Meeting, Seattle, WA, November 4-7, 2010.

Atlantoaxial instability results from cartilaginous destruction, periarticular erosions, and ligament and tendon attenuation. Instability affects 19%-70% of patients, and basilar invagination from vertical odontoid subluxation through the foramen magnum occurs in 38% of patients. This phenomenon occurs twice as often in women than men, whose age at diagnosis typically ranges from 30-50 years. Along with bony compression, the pannus further decreases the space available for the cord by 3mmor more in approximately 66% of patients (Figures 1-7). The earliest and most common symptom of cervical …


Receptor Antagonism And Dyskinesia In Parkinson’S Disease, Micaela Morelli, Fabio Blandini, Nicola Simola, Robert A. Hauser Jan 2012

Receptor Antagonism And Dyskinesia In Parkinson’S Disease, Micaela Morelli, Fabio Blandini, Nicola Simola, Robert A. Hauser

Neurology Faculty Publications

Dyskinesia, a major complication of treatment of Parkinson’s disease (PD), involves two phases: induction, which is responsible for dyskinesia onset, and expression, which underlies its clinical manifestation. The unique cellular and regional distribution of adenosine receptors in basal ganglia areas that are richly innervated by dopamine, and their antagonistic role towards dopamine receptor stimulation, have positioned receptor antagonists as an attractive nondopaminergic target to improve the motor deficits that characterize PD. In this paper, we describe the biochemical characteristics of receptors and the effects of adenosine antagonists in rodent and primate models of PD on L-DOPA-induced dyskinesia, together with relevant …


Neuroangiogenesis: A Vascular Basis For Alzheimer's Disease And Cognitive Decline During Aging, Charles T. Ambrose Jan 2012

Neuroangiogenesis: A Vascular Basis For Alzheimer's Disease And Cognitive Decline During Aging, Charles T. Ambrose

Microbiology, Immunology, and Molecular Genetics Faculty Publications

Angiogenesis directs development of the brain's microcirculation during antenatal and postnatal development, but its role later in life is less well recognized. I contend that during senescence a reduced cerebral capillary density accounts in part for the vascular cognitive impairment observed in many older persons and possibly for some forms of Alzheimer's disease. I propose that neuroangiogenesis is essential throughout adult life for maintaining the microcirculation of the cerebral cortex and elsewhere in the brain and that it commonly declines with old age. To support this hypothesis I have examined the neurological literature for relevant studies on cerebral capillary density …

Bickerstaff’S Brainstem Encephalitis, Miller Fisher Syndrome And Guillain-Barré Syndrome Overlap In An Asthma Patient With Negative Anti-Ganglioside Antibodies, Chongyu Han, Yuan Wang, Jianping Jia, Xunming Ji, Vance Fredrickson, Yuchuan Ding, Wei Sun, Jia Xu, Yong-Xin Sun

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

Bickerstaff’s brainstem encephalitis (BBE), together with Miller Fisher syndrome (MFS) and Guillain-Barré syndrome (GBS) were considered to form a continuous clinical spectrum. An anti-GQ1b antibody syndrome has been proposed to underlie the common pathophysiology for the three disorders; however, other studies have found a positive anti-GM1 instead of anti-GQ1b antibody.

Case presentation

Here we report a 20-year-old male patient with overlapping BBE, MFS and GBS. The patient had a positive family history of bronchial asthma and had suffered from the condition for over 15 years. He developed BBE symptoms nine days after an asthma exacerbation. During the course …

Wayne State University Associated BioMed Central Scholarship

Abstract

Background

This paper presents a three-dimensional (3D) method for segmenting corpus callosum in normal subjects and brain cancer patients with glioblastoma.

Methods

Nineteen patients with histologically confirmed treatment naïve glioblastoma and eleven normal control subjects underwent DTI on a 3T scanner. Based on the information inherent in diffusion tensors, a similarity measure was proposed and used in the proposed algorithm. In this algorithm, diffusion pattern of corpus callosum was used as prior information. Subsequently, corpus callosum was automatically divided into Witelson subdivisions. We simulated the potential rotation of corpus callosum under tumor pressure and studied the reproducibility of the …


Multimodal Imaging Evidence For Axonal And Myelin Deterioration In Amnestic Mild Cognitive Impairment, Brian T. Gold, Yang Jiang, David K. Powell, Charles D. Smith Jan 2012

Multimodal Imaging Evidence For Axonal And Myelin Deterioration In Amnestic Mild Cognitive Impairment, Brian T. Gold, Yang Jiang, David K. Powell, Charles D. Smith

Neuroscience Faculty Publications

White matter (WM) microstructural declines have been demonstrated in Alzheimer's disease and amnestic mild cognitive impairment (aMCI). However, the pattern of WM microstructural changes in aMCI after controlling for WM atrophy is unknown. Here, we address this issue through joint consideration of aMCI alterations in fractional anisotropy, mean diffusivity, axial diffusivity, and radial diffusivity, as well as macrostructural volume in WM and gray matter compartments. Participants were 18 individuals with aMCI and 24 healthy seniors. Voxelwise analyses of diffusion tensor imaging data was carried out using tract-based spatial statistics (TBSS) and voxelwise analyses of high-resolution structural data was conducted using …


Elderly Onset Of Weakness In Facioscapulohumeral Muscular Dystrophy, Dominic B. Fee Jan 2012

Elderly Onset Of Weakness In Facioscapulohumeral Muscular Dystrophy, Dominic B. Fee

Neurology Faculty Publications

A 77-year-old male is presented. He had onset of proximal weakness 10 years earlier. His course was slowly progressive. Despite having phenotypic features of facioscapulohumeral muscular dystrophy (FSH), genetic testing for this was delayed because of his age of onset, lack of family history, and benign appearing muscle biopsy. This case is one of the oldest onset of weakness in genetically confirmed FSH and highlights the recognized expansion in phenotype that has occurred since the advent of genetic testing.
