Neuropsychology Abstract of the Day: Neurodegeneration in Alzheimer Disease

de Jong LW, van der Hiele K, Veer IM, Houwing JJ, Westendorp RG, Bollen EL, de Bruin PW, Middelkoop HA, van Buchem MA, & van der Grond J. Strongly reduced volumes of putamen and thalamus in Alzheimer's disease: An MRI study. Brain. 2008 Nov 20. Department of Radiology, Section Neuropsychology of the Department of Neurology, Department of Medical Statistics, Department of Geriatrics and Department of Neurology of the Leiden University Medical Center, Leiden, The Netherlands. Atrophy is regarded a sensitive marker of neurodegenerative pathology. In addition to confirming the well-known presence of decreased global grey matter and hippocampal volumes in Alzheimer's disease, this study investigated whether deep grey matter structure also suffer degeneration in Alzheimer's disease, and whether such degeneration is associated with cognitive deterioration. In this cross-sectional correlation study, two groups were compared on volumes of seven subcortical regions: 70 memory...

The GEM Study

From an NIH press release earlier today: Ginkgo Evaluation of Memory (GEM) Study Fails To Show Benefit in Preventing Dementia in the Elderly The dietary supplement Ginkgo biloba was found to be ineffective in reducing the development of dementia and Alzheimer's disease in older people, according to a study published in the Journal of the American Medical Association1. Researchers led by Stephen T. DeKosky, M.D., formerly of the University of Pittsburgh, vice president and dean of the School of Medicine at the University of Virginia in Charlottesville, conducted the trial known as the Ginkgo Evaluation of Memory (GEM) study at four clinical sites over the course of 8 years. GEM is the largest clinical trial ever to evaluate ginkgo's effect on the occurrence of dementia. This research was co-funded by five components of the National Institutes of Health (NIH): National Center for Complementary and Alternative Medicine (NCCAM); National Institute on Aging (NIA); National Heart, Lu...

Neuropsychology Abstract of the Day: Alzheimer's Disease Drug Development

Becker RE & Greig NH. Alzheimer's disease drug development in 2008 and beyond: Problems and opportunities. Current Alzheimer Research . 2008 Aug; 5(4): 346-357. Drug Design & Development Section, Laboratory of Neurosciences, Intramural Research Program, National Institute on Aging, National Institutes of Health, Baltimore, MD 21224, USA. Recently, a number of Alzheimer's disease (AD) multi-center clinical trials (CT) have failed to provide statistically significant evidence of drug efficacy. To test for possible design or execution flaws we analyzed in detail CTs for two failed drugs that were strongly supported by preclinical evidence and by proven CT AD efficacy for other drugs in their class. Studies of the failed commercial trials suggest that methodological flaws may contribute to the failures and that these flaws lurk within current drug development practices ready to impact other AD drug development [1]. To identify and counter risks we considered the relevance...

Internet Use Good For Brain Circuitry, As Well As For The WWW

From The BBC: Internet use 'good for the brain' Read the full article [snip] Lead researcher Professor Gary Small said: "The study results are encouraging, that emerging computerized technologies may have physiological effects and potential benefits for middle-aged and older adults. "Internet searching engages complicated brain activity, which may help exercise and improve brain function." The latest study was based on 24 volunteers aged between 55 and 76. Half were experienced internet users, the rest were not. Each volunteer underwent a brain scan while performing web searches and book-reading tasks. Both types of task produced evidence of significant activity in regions of the brain controlling language, reading, memory and visual abilities. However, the web search task produced significant additional activity in separate areas of the brain which control decision-making and complex reasoning - but only in those who were experienced web users. The researchers ...

Neuropsychology Abstract of the Day: Post-operative Pain, Cognition, and PCA Techniques

Benzion Beilin; Dan Hoofien; Ravit Poran; Inbal Gral; Galina Grinevich; Berta Butin; Eduard Mayburd; & Yehuda Shavit. Comparison of two patient-controlled analgesia techniques on neuropsychological functioning in the immediate postoperative period. Journal of Clinical and Experimental Neuropsychology, Volume 30, Issue 6, August 2008, 674-682. Pain may contribute to cognitive decline, which is a common complication in the early postoperative period. We compared the effects of two common pain management techniques, intravenous patient-controlled analgesia (PCA-IV) and patient-controlled epidural analgesia (PCEA), on cognitive functioning in the immediate postoperative period. Patients hospitalized for elective surgery were randomly assigned to one of the treatment groups (30 patients per group). A battery of objective, standardized neuropsychological tests was administered preoperatively and 24 hours after surgery. Pain intensity was also evaluated. Nonoperated volunteers se...

Brain Banks

From the CBC : Brain banks: Crucial for research, clamouring for donors Last Updated: Monday, September 22, 2008 | 7:56 AM ET By Gloria Troyer CBC News Read the full article [snip] Brain banks. The work they do is not widely publicized — most people who consider signing donor cards think along the lines of organs such as the hearts and kidneys for transplant — but it's crucial for many researchers trying to understand the causes and characteristics of myriad diseases. "Brain donations and brain banks are absolutely essential to neurological and psychiatric research," says Dr. Margaret Fahnestock, professor of neuroscience in the department of psychiatry and behavioural neurosciences at McMaster University in Hamilton. "One of the main reasons is that there are few to no good cellular or animal models of most neuropsychiatric conditions — schizophrenia and autism, for example," she says. "This is because we currently have a poor understanding of the cellular...

Neuropsychology Abstract of the Day: Epilepsy

Frings L, Wagner K, Maiwald T, Carius A, Schinkel A, Lehmann C, & Schulze-Bonhage A. Early detection of behavioral side effects of antiepileptic treatment using handheld computers. Epilepsy and Behavior. 2008 Aug; 13(2) :402-406. Epilepsy Center, University Hospital of Freiburg, Freiburg, Germany. OBJECTIVE: Treatment-emergent side effects are frequent events, particularly during the uptitration of antiepileptic drugs. So far, monitoring of such adverse events in outpatients has often been limited to intervals of weeks or months. We here report the application of a new device for temporally fine-grained assessment of objective well-being and cognitive performance using personal digital assistants (PDAs). METHODS: Twenty adult patients with epilepsy participated in this pilot study. Ten received add-on treatment with levetiracetam. Ten patients with constant medication served as a control group. Differences between groups with respect to self-rated cognitive condition, psychophysi...

The Quality Assurance Program also establishes benchmarks to monitor the...

Obit: Robert Katzman

Dr. Robert Katzman dies at 82; neuroscientist identified Alzheimer's disease as a 'major killer' By Thomas H. Maugh II, Los Angeles Times Staff Writer Los Angeles Times September 20, 2008 Link Dr. Robert Katzman, the UC San Diego neuroscientist who pushed Alzheimer's disease into the public consciousness as a "major killer" and who co-founded the activist Alzheimer's Assn., died Tuesday at his home in La Jolla after a long illness. He was 82. Katzman played a major role in making San Diego one of the major centers for Alzheimer's research in the United States, if not the world, bringing prominent neuroscientists and major funding to a program that had been virtually nonexistent before his arrival in 1984. "His pioneering and, really, revolutionary work in Alzheimer's disease for more than three decades paved the way for clinical trials of potential treatments to delay the onset or progression of the disease being done today," said neuros...

Neuropsychology Abstract of the Day: Pain Assessment

Jensen MP, Mardekian J, Lakshminarayanan M, & Boye ME. Validity of 24-h recall ratings of pain severity: Biasing effects of "Peak" and "End" pain. Pain. 2008 Jul 15; 137(2): 422-427. Department of Rehabilitation Medicine, Box 356490, University of Washington School of Medicine, Seattle, WA 98195-6490, USA. Despite the frequent use of pain recall ratings in clinical research, there remains doubt about the ability of individuals to accurately recall their pain. In particular, previous research indicates the possibility that the most pain experienced during a recall period and the most recent pain experienced (known as peak and end effects, respectively) might bias recall ratings. The current study used data from a published clinical trial to determine the relative validity of a 24-h recall rating of average post-operative pain and the nature and extent of any biasing influence of peak and end effects on nine separate 24-h recall ratings. The results supported a...

Neuropsychology Abstract of the Day: Parkinson's Disease and Olfaction

Landis BN & Burkhard PR. Phantosmias and Parkinson disease. Archives of Neurology . 2008 Sep; 65(9): 1237-1239. BACKGROUND: Impaired olfaction is a common, nonmotor manifestation of Parkinson disease (PD). However, to our knowledge, qualitative olfactory disturbances, such as odor distortions, have not been extensively reported in this condition. OBJECTIVE: To describe 2 patients who reported positive olfactory symptoms preceding typical PD, which were consistent with olfactory hallucinations (phantosmias) in the absence of major smell deficit. DESIGN: Case series. SETTING: University hospital. Patients We describe 2 patients, both seen in 2007, who reported pleasant olfactory hallucinations for several years. MAIN OUTCOME MEASURES: Iodine I 123-labeled ioflupane single-photon emission computed tomography and olfactometric testing results.

Neuropsychology Abstract of the Day: Verbal Fluency and MCI

Nutter-Upham KE, Saykin AJ, Rabin LA, Roth RM, Wishart HA, Pare N, Flashman LA. Verbal fluency performance in amnestic MCI and older adults with cognitive complaints. Archives of Clinical Neuropsychology . 2008 May; 23(3): 229-241. Neuropsychology Program, Department of Psychiatry, Dartmouth Medical School/DHMC, Lebanon, NH, USA. Verbal fluency tests are employed regularly during neuropsychological assessments of older adults, and deficits are a common finding in patients with Alzheimer's disease (AD). Little extant research, however, has investigated verbal fluency ability and subtypes in preclinical stages of neurodegenerative disease. We examined verbal fluency performance in 107 older adults with amnestic mild cognitive impairment (MCI, n=37), cognitive complaints (CC, n=37) despite intact neuropsychological functioning, and demographically matched healthy controls (HC, n=33). Participants completed fluency tasks with letter, semantic category, and semantic switching constrain...

On the New York Times website: Earlier diagnosis giving Alzheimer's a new voice By THE ASSOCIATED PRESS Published: June 2, 2008 Filed at 4:26 p.m. ET "WASHINGTON (AP) -- Don Hayen has a handy way of deflecting the instant pity that comes when he reveals his Alzheimer's disease: "But I haven't lost my keys all day," he quickly jokes. Hayen is part of a growing new movement in Alzheimer's: Patients diagnosed early enough to still be articulate and demand better care and better research. They are giving a voice to a disease whose victims until now have remained largely silent, and powerless. It's a shift with big ramifications." [ ... Read the full article ... ]

Three Brainy General-Readership Books

Just finished reading three excellent books with neuro themes, one a work of fiction and the other two are narrative accounts: "Still Alice" by Lisa Genova (available in paperback by iUniverse Press), is a very accurate dramatic fictional account of early-onset Alzheimer's disease. "Insomniac" by Gayle Greene is a great account of the world of insomnia, from the vantage point of individuals living with sleep disorders (including the author) and from the vantage point of the clinical researchers who study the condition and who work on drug development and other facets of diagnosis, understanding, and treatment. Finally, "Can't Remember What I Forgot" by Sue Halpern , self described as a "behind-the-scenes foray into the world of cutting-edge memory research." It lives up to that description and does so in a very readable manner. "Insomniac" is published by the University of California Press and "Can't Remember ......

Analysis of the Neurotechnology Industry

The Ultimate Cure by David Ewing Duncan CondeNast Portfolio May 2008 "The neurotech industry is engaged in a $2 trillion race to fix your brain. Many players will fail, but the payoff will be huge for those who succeed." [snip] "Neurotech’s returns are already enormous. In 2006, the industry brought in more than $120 billion—about $101 billion from drugs and the rest from neurodevices ($4.5 billion) and neurodiagnostics ($15 billion)—up 10 percent from the previous year, reports NeuroInsights, a market research and investment advisory firm. But industry analysts insist that this figure hardly begins to suggest the potential. For Alzheimer’s, a disease currently without an effective treatment for about 4.5 million sufferers in the U.S., 40 companies—including behemoths like Eli Lilly, GlaxoSmithKline, and Wyeth, as well as Targacept and a gaggle of similar upstarts—are testing 48 new drugs in human trials in a quest for the Prozac of dementia. The push has brought many ...

Neuropsychology Abstract of the Day: Parkinson's Disease and Olfaction

Kranick SM, & Duda JE. Olfactory dysfunction in Parkinson's disease. Neurosignals. 2008; 16(1): 35-40. Department of Neurology, University of Pennsylvania School of Medicine, Philadelphia, PA, USA. Prior to the onset of the cardinal motor features of idiopathic Parkinson's disease (PD), other manifestations of neurodegeneration such as olfactory dysfunction are often apparent. Characterizing these potential biomarkers of preclinical PD is particularly important in identifying individuals who will go on to develop disabling symptoms, and thus be good candidates for new neuroprotective strategies. As shown by the Braak neuropathologic staging of PD, the olfactory system is among the first neuronal populations to display Lewy body pathology. Clinically, loss of smell can be easily tested in the office using several validated techniques and is often helpful to the physician in distinguishing idiopathic PD from other forms of parkinsonism. Recent findings have indicated that a...

Neuropsychology Abstract of the Day: Parkinson's Disease

Pagonabarraga J, Kulisevsky J, Llebaria G, García-Sánchez C, Pascual-Sedano B, & Gironell A. Parkinson's disease-cognitive rating scale: A new cognitive scale specific for Parkinson's disease. Movement Disorders. 2008 Mar 31 [Epub ahead of print]. Movement Disorders Unit, Neurology Department, Sant Pau Hospital, Autonomous University of Barcelona, and Centro de Investigación Biomédica en Red sobre Enfermedades Neurodegenerativas (CIBERNED), Spain. Cognitive defects associated with cortical pathology may be a marker of dementia in Parkinson's disease (PD). There is a need to improve the diagnostic criteria of PD dementia (PDD) and to clarify the cognitive impairment patterns associated with PD. Current neuropsychological batteries designed for PD are focused on fronto-subcortical deficits but are not sensitive for cortical dysfunction. We developed a new scale, the Parkinson's Disease-Cognitive Rating Scale (PD-CRS), that was designed to cover the full spectrum of...

Neuropsychology Abstract of the Day: Frontotemporal Dementia

Wittenberg D, Possin KL, Rascovsky K, Rankin KP, Miller BL, & Kramer JH. The Early Neuropsychological and Behavioral Characteristics of Frontotemporal Dementia. Neuropsychological Review. 2008 Feb 29 [Epub ahead of print] Memory and Aging Center, University of California—San Francisco Medical Center, San Francisco, CA, USA. Frontotemporal lobar degeneration (FTLD) represent a constellation of disorders that may be overlooked or misdiagnosed, despite being fairly common presenile neurodegenerative diseases. Although the cognitive disorder can be difficult to document, particularly early in the dementia course, neuropsychological evaluation can assist in the diagnosis. Neuropsychologists are in an excellent position to draw from related disciplines like personality theory and social psychology to better assess the types of changes that characterize the prodromal and early phases of the disease. This review summarizes the current state of the field in the diagnosis of FTLD and disc...

Neuropsychology Abstract of the Day: Mild Cognitive Impairment (MCI)

Bondi MW, Jak AJ, Delano-Wood L, Jacobson MW, Delis DC, & Salmon DP. Neuropsychological Contributions to the Early Identification of Alzheimer's Disease. Neuropsychological Review. 2008 Mar 18. A wealth of evidence demonstrates that a prodromal period of Alzheimer's disease (AD) exists for some years prior to the appearance of significant cognitive and functional declines required for the clinical diagnosis. This prodromal period of decline is characterized by a number of different neuropsychological and brain changes, and reliable identification of individuals prior to the development of significant clinical symptoms remains a top priority of research. In this review we provide an overview of those neuropsychological changes. In particular, we examine specific domains of cognition that appear to be negatively affected during the prodromal period of AD, and we review newer analytic strategies designed to examine cognitive asymmetries or discrepancies between higher-order ...

Neuropsychology Abstract of the Day: Schizophrenia Clinical Trials

Hill SK, Sweeney JA, Hamer RM, Keefe RS, Perkins DO, Gu H, McEvoy JP, & Lieberman JA. Efficiency of the CATIE and BACS neuropsychological batteries in assessing cognitive effects of antipsychotic treatments in schizophrenia. Journal of the International Neuropsychological Society. 2008 Mar; 14(2): 209-221. Center for Cognitive Medicine, Department of Psychiatry, University of Illinois at Chicago, Chicago, Illinois. Efficient and reliable assessments of cognitive treatment effects are essential for the comparative evaluation of procognitive effects of pharmacologic therapies. Yet, no studies have addressed the sensitivity and efficiency with which neurocognitive batteries evaluate cognitive abilities before and after treatment. Participants were primarily first episode schizophrenia patients who completed baseline (n = 367) and 12-week (n = 219) assessments with the BACS (Brief Assessment of Cognition in Schizophrenia) and CATIE (Clinical Antipsychotic Trials of Intervention Effe...

Memory

A press release rom the NIH: Genetic Tags Reveal Secrets of Memories’ Staying Power in Mice A better understanding of how memory works is emerging from a newfound ability to link a learning experience in a mouse to consequent changes in the inner workings of its neurons. Researchers, supported in part by the National Institutes of Health's National Institute of Mental Health (NIMH), have developed a way to pinpoint the specific cellular components that sustain a specific memory in genetically-engineered mice. "Remarkably, this research demonstrates a way to untangle precisely which cells and connections are activated by a particular memory," said NIMH Director Thomas Insel, M.D. "We are actually learning the molecular basis of learning and memory." For a memory to last long-term, the neural connections holding it need to be strengthened by incorporating new proteins triggered by the learning. Yet, it's been a mystery how these new proteins — born deep inside...

Neuropsychology Abstract of the Day: Aphasia

Baldo JV, Klostermann EC, & Dronkers NF. It's either a cook or a baker: Patients with conduction aphasia get the gist but lose the trace. Brain and Language . 2008 Feb 1 [Epub ahead of print] VA Northern California Health Care System, Center for Aphasia and Related Disorders, 150 Muir Road (126s), Martinez, CA 94553, USA. Patients with conduction aphasia have been characterized as having a short-term memory deficit that leads to relative difficulty on span and repetition tasks. It has also been observed that these same patients often get the gist of what is said to them, even if they are unable to repeat the information verbatim. To study this phenomenon experimentally, patients with conduction aphasia and left hemisphere-injured controls were tested on a repetition recognition task that required them to listen to a sentence and immediately point to one of three sentences that matched it.

From today's New York Times : A Medical Mystery Unfolds in Minnesota By DENISE GRADY Published: February 5, 2008 [snip] By then, November 2007, other cases had begun to turn up. Ultimately, there were 12 — 6 men and 6 women, ranging in age from 21 to 51. Doctors and the plant owner, realizing they had an outbreak on their hands, had already called in the Minnesota Department of Health, which, in turn, sought help from the federal Centers for Disease Control and Prevention. Though the outbreak seemed small, the investigation took on urgency because the disease was serious, and health officials worried that it might indicate a new risk to other workers in meatpacking. “It is important to characterize this because it appears to be a new syndrome, and we don’t truly know how many people may be affected throughout the U.S. or even the world,” said Dr. Jennifer McQuiston, a veterinarian from the disease centers. In early November, Dr. Aaron DeVries, a health department epidemiologist, vi...

Progressive Inflammatory Neuropathy (PIN)

From the CDC's Morbidity and Mortality Weekly Report (MMWR) on 31 January 2008: Investigation of Progressive Inflammatory Neuropathy Among Swine Slaughterhouse Workers --- Minnesota, 2007---2008 [snip] "This report summarizes an ongoing investigation of PIN, a syndrome that appears to be associated with swine slaughterhouse workers who process pig heads. Several clinical and laboratory features of this illness and the distinctive epidemiology associated with patients appear unique. Pigs slaughtered at plant A have passed inspection by the U.S. Department of Agriculture Food Safety and Inspection Service, and the investigation has not identified any foodborne risk to the general population. "The investigation in Minnesota indicates that PIN appears associated with having worked at the head table, where a compressed-air device was used to extract pig brains. In the process of blowing compressed air into the pig skull, brain material might have been splattered or even aeros...

Neuropsychology Abstract of the Day: Mild Cognitive Impairment (MCI)

Unverzagt FW, Sujuan Gao , Lane KA, Callahan C, Ogunniyi A, Baiyewu O, Gureje O, Hall KS, & Hendrie HC. Mild cognitive dysfunction: An epidemiological perspective with an emphasis on African Americans. Geriatrics Psychiatry & Neurology. 2007 Dec; 20(4): 215-226. Department of Psychiatry, Indiana University School of Medicine, Indianapolis, IN 46202, USA. This review begins with a historical accounting of the evolution of the concept of mild cognitive dysfunction, including nomenclature and criteria from Kral to Petersen. A critical analysis of the main elements relating to assessment and diagnosis of mild cognitive dysfunction is provided. Methodological limitations in design, measurement, and characterization, especially as they relate to older African Americans, are identified. Data from a 15-year longitudinal study of community-dwelling African Americans in Indianapolis, Indiana, indicate a 23% prevalence of all-cause mild cognitive dysfunction, with approximately 25% pr...

Neuropsychology Abstract of the Day: Mild Cognitive Impairment (MCI)

Fleisher AS, Sun S, Taylor C, Ward CP, Gamst AC, Petersen RC, Jack CR, Aisen PS, & Thal LJ. Volumetric MRI vs clinical predictors of Alzheimer disease in mild cognitive impairment. Neurology. 2008 Jan 15; 70(3): 191-199. OBJECTIVE: To compare volumetric MRI of whole brain and medial temporal lobe structures to clinical measures for predicting progression from amnestic mild cognitive impairment (MCI) to Alzheimer disease (AD). METHODS: Baseline MRI scans from 129 subjects with amnestic MCI were obtained from participants in the Alzheimer's Disease Cooperative Study group's randomized, placebo-controlled clinical drug trial of donepezil, vitamin E, or placebo. Measures of whole brain, ventricular, hippocampal, and entorhinal cortex volumes were acquired. Participants were followed with clinical and cognitive evaluations until formal criteria for AD were met, or completion of 36 months of follow-up. Logistic regression modeling was done to assess the predictive value of all ...

Neuropsychology Abstract of the Day: Stroke Rehab Outcome Assessment

Salter KL, Teasell RW, Foley NC, & Jutai JW. Outcome assessment in randomized controlled trials of stroke rehabilitation. American Journal of Physical Medicine and Rehabilitation. 2007 Dec ;86(12): 1007-1012. Department of Physical Medicine and Rehabilitation, St. Joseph's Healthcare London, London, Canada. The lack of a unified approach to outcome assessment in stroke rehabilitation limits our ability to interpret evidence provided by randomized controlled trials (RCTs). The purpose of this review was to identify outcomes and assessment tools reported in RCTs of stroke rehabilitation interventions as a first step toward consistent assessment of outcomes. Given that the validity of research is linked to reliability and validity of measurement, the relationship between the use of previously developed outcome measures and the methodological quality of RCTs was explored.Electronic literature searches identified RCTs examining stroke rehabilitation therapies from 1968 to 2005. Th...

Neuropsychology Abstract of the Day: Desires for Caffeine

Okay, sitting in a coffeehouse right now, how could I not choose this abstract! West O, & Roderique-Davies G. Development and initial validation of a caffeine craving questionnaire. Journal of Psychopharmacology. 2008 Jan; 22(1):80-91. Department of Psychology, HaSS, University of Glamorgan, Pontypridd, CF37 1DL, UK. Craving for caffeine has received little empirical attention, despite considerable research into the potential for caffeine dependence. The main aim of this study was to develop, and initially validate, a multi-item, multidimensional instrument to measure cravings for caffeine. Participants were 189 caffeine consumers who completed the Questionnaire of Caffeine Cravings, which was based on the Questionnaire of Smoking Urges (QSU), in one of five naturally occurring periods of abstinence; 1-15 min; 16-120 mins; 3-7 h; 12-48 h and +48 h. Exploratory factor analysis suggested a three-factor solution best described the data; Factor 1 reflected strong desires, intention...
