SenseCam

Microsoft's research project: SenseCam SenseCam and memory functioning Here is a recently published research study: SenseCam improves memory for recent events and quality of life in a patient with memory retrieval difficulties. Memory . 2011 Sep 26; Browne G, Berry E, Kapur N, Hodges S, Smyth G, Watson P, Wood K Abstract A wearable camera that takes pictures automatically, SenseCam, was used to generate images for rehearsal, promoting consolidation and retrieval of memories for significant events in a patient with memory retrieval deficits. SenseCam images of recent events were systematically reviewed over a 2-week period. Memory for these events was assessed throughout and longer-term recall was tested up to 6 months later. A written diary control condition followed the same procedure. The SenseCam review procedure resulted in significantly more details of an event being recalled, with twice as many details recalled at 6 months follow up compared to the written diary method. Self-...

Neuropsychology Abstract of the Day: When Participants Abort a Test Performance

Correlates of quitting the Paced Auditory Serial Addition Test in cognitively normal older adults participating in a study of normal cognitive aging Journal of Clinical and Experimental Neuropsychology. 2011 Oct;33(8):937-43. Epub 2011 Jun 27. Locke DE, Stonnington CM, Thomas ML, Caselli RJ. Abstract Our study of cognitive aging involves a comprehensive battery of neuropsychological measures. The Paced Auditory Serial Addition Test (PASAT) is the only test that some of our participants will refuse to complete. We explored variables related to quitting versus completing the PASAT in this sample of normal older adults. We hypothesized that quitting would be related to personality features, subclinical anxiety symptoms, demographics, and/or Wechsler Adult Intelligence Scale-Revised (WAIS-R) Arithmetic performance. A logistical regression model including NEO Personality Inventory-Revised (NEO-PI-R) depression and excitement seeking, age, and WAIS-R Arithmetic classified participants with...

Neuropsychology Abstract of the Day: Cognitive Correlates of Impulsive Behavior in Mlld Alzheimer's Disease

A multidimensional approach to impulsivity changes in mild Alzheimer's disease and control participants: Cognitive correlates Cortex . 2011 Sep 2; Rochat L, Billieux J, Juillerat Van der Linden AC, Annoni JM, Zekry D, Gold G, Van der Linden M Abstract INTRODUCTION: Impulsive behaviors are frequently described in brain-damaged patients, including patients with Alzheimer's disease (AD). However, few studies have examined impulsivity changes and associated cognitive impairments in AD and healthy controls. Consequently, the first aim of this study was to compare patients with mild AD and matched controls on four dimensions of impulsivity (urgency, lack of premeditation, lack of perseverance, and sensation seeking) recently highlighted in the literature. The second objective was to examine the association between impulsivity changes and cognitive performances on executive/attentional tasks in mild AD and healthy controls. METHODS: Thirty patients with mild AD and 30 matched controls...

Prescribed Stimulant Use for ADHD Continues to Rise Steadily

A press release from the NIH: Prescribed stimulant use for ADHD continues to rise steadily NIH and AHRQ study finds pace of the rise has slowed in recent years "The prescribed use of stimulant medications to treat attention deficit hyperactivity disorder (ADHD) rose slowly but steadily from 1996 to 2008, according to a study conducted by the National Institutes of Health (NIH) and the Agency for Healthcare Research and Quality (AHRQ). The study was published online ahead of print Sept. 28, 2011, in the American Journal of Psychiatry . "ADHD is one of the most common childhood disorders, and can continue through adolescence and adulthood. Symptoms include difficulty staying focused and paying attention, difficulty controlling behavior, and hyperactivity (over-activity). The condition is frequently treated with stimulants such as methylphenidate (e.g., Ritalin), amphetamines (e.g., Adderall) or other types of medications. Behavioral therapies can also be effective. "During...

Neuropsychology Abstract of the Day: Aphasia Screening for Stroke Patients

Validation of the language component of the Addenbrooke's Cognitive Examination - Revised (ACE-R) as a screening tool for aphasia in stroke patients. Australas J Ageing . 2011 Sep;30(3):156-8 Authors: Gaber TA, Parsons F, Gautam V Abstract Aim:  Several tests are available for aphasia screening following stroke. However, some of them have shortcomings such as need of specialist knowledge, low sensitivity and/or specificity and lengthy administration time. Our study aims to evaluate the language component of the Addenbrooke's Cognitive Examination - Revised (ACE-R) as a screening tool for aphasia in stroke patients. Methods:  The language component of ACE-R was administered to consecutive patients admitted to a post-acute stroke unit. Patients who were medically unstable or had a significant history of sensory impairment or mental health issues were excluded. The test was administered by two junior doctors with basic training in ACE-R administration. Patients recruited were also...

Neuropsychology Abstract of the Day: Assessment of Social Cognition in TBI

An active area of test development and research in contemporary clinical neuropsychology: Social Cognition Impairments in Relation to General Cognitive Deficits, Injury Severity and Prefrontal Lesions in Traumatic Brain Injury Patients. Journal of Neurotrauma . 2011 Sep 20; Authors: Spikman JM, Van der Naalt J, Timmerman ME, Milders MV, Veenstra WS Abstract Impairments in social behavior are frequently found in moderate to severe TBI patients and are associated with an unfavorable outcome with regard to return to work and social reintegration. Neuropsychological tests measuring aspects of social cognition are thought to be sensitive to these problems. However, little is known about the effect of general cognitive problems on these tests, nor about their sensitivity to injury severity and frontal lesions. In the present study 28 chronic TBI patients with a moderate to severe TBI were assessed with tests for social cognition (emotion recognition, Theory of Mind and empathy) and for gener...

Neuropsychology Abstract of the Day: Art and Neuroscience

Today's recommended paper reflects one of my research interests when I was an undergraduate: Experiencing Art: The Influence of Expertise and Painting Abstraction Level. Frontiers in Human Neuroscience. 2011;5:94 Authors: Pihko E, Virtanen A, Saarinen VM, Pannasch S, Hirvenkari L, Tossavainen T, Haapala A, Hari R Abstract How does expertise influence the perception of representational and abstract paintings? We asked 20 experts on art history and 20 laypersons to explore and evaluate a series of paintings ranging in style from representational to abstract in five categories. We compared subjective esthetic judgments and emotional evaluations, gaze patterns, and electrodermal reactivity between the two groups of participants. The level of abstraction affected esthetic judgments and emotional valence ratings of the laypersons but had no effect on the opinions of the experts: the laypersons' esthetic and emotional ratings were highest for representational paintings and lowest for...

Neuropsychology Abstract of the Day: Amnestic Mild Cognitive Impairment (aMCI)

Outcome of Mild Cognitive Impairment Comparing Early Memory Profiles. American Journal of Geriatric Psychiatry . 2011 Sep 19; Authors: Gómez-Tortosa E, Mahillo-Fernández I, Guerrero R, Montoya J, Alonso A, Sainz MJ Abstract BACKGROUND:: Finding variables that predict decline or stability in persons with amnestic mild cognitive impairment (aMCI) is an important step in identifying subjects in prodromal stages of dementia. This study tests a clinical observation suggesting that aMCI cases with better-preserved recognition skills, despite similar delayed recall deficits, are more likely to remain functionally stable. METHODS:: A cohort of 210 cases with aMCI, diagnosed with standardized criteria that had been followed up for 48 ± 12 months (range: 36-100), were divided into two groups according to their initial recognition memory discrimination index (DI) on the Hopkins Verbal Learning Test (DI ≥ or PMID: 21934475 [PubMed - as supplied by publisher]

A phase 2 randomized trial of ELND005, scyllo-inositol, in mild to moderate Alzheimer disease. Neurology . 2011 Sep 14; Authors: Salloway S, Sperling R, Keren R, Porsteinsson AP, van Dyck CH, Tariot PN, Gilman S, Arnold D, Abushakra S, Hernandez C, Crans G, Liang E, Quinn G, Bairu M, Pastrak A, Cedarbaum JM. Abstract OBJECTIVE:This randomized, double-blind, placebo-controlled, dose-ranging phase 2 study explored safety, efficacy, and biomarker effects of ELND005 (an oral amyloid anti-aggregation agent) in mild to moderate Alzheimer disease (AD). METHODS:A total of 353 patients were randomized to ELND005 (250, 1,000, or 2,000 mg) or placebo twice daily for 78 weeks. Coprimary endpoints were the Neuropsychological Test Battery (NTB) and Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL) scale. The primary analysis compared 250 mg (n = 84) to placebo (n = 82) after an imbalance of infections and deaths led to early discontinuation of the 2 higher dose groups. ...

Neuropsychology Abstract of the Day: Disability Scale for DM1

Development of a disability scale for myotonic dystrophy type 1. Acta Neurol Scand. 2011 Sep 8; Authors: Contardi S, Pizza F, Falzone F, D'Alessandro R, Avoni P, Di Stasi V, Montagna P, Liguori R Abstract Objectives -  Myotonic dystrophy type 1 (DM1) is a multisystem disorder. Many tests in the literature have evaluated single aspects of DM1 patients, mainly focusing on muscular impairment, without an overall quantification of the different disease-specific neurological features. We developed and validated a new functional scale for DM1 patients based on neuromuscular impairment (NI) and disability. Materials and methods -  Thirty-three patients were tested in basal condition, 18 were re-evaluated after therapeutic intervention with mexiletine, and 13 at one year follow-up without treatment. The scale includes 21 ordinal items in four areas: neuropsychology, motricity, myotonia and daily life activities. We evaluated inter- and intra-observer reliability (intraclass correlation c...

"Autobiographer": Theatre Production on Alzheimer's Theme

New show, ‘Autobiographer’, to tour the UK and Ireland this autumn 02 September 2011 From the website: "A new production from award-winning theatre artist Melanie Wilson begins a tour of the UK and Ireland this autumn. Part sound installation, part theatre performance, ‘Autobiographer’ reveals a curious and evocative portrait of a life refracted through the lens of dementia. "Autobiographer is about memory: the memory of a 76-year-old woman, Flora. Flora has a dementia, but the piece is not about dementia itself - rather, it is about how she recalls her full and long life as her memories unravel and become unreliable. Voiced by multiple performers, four actors play the role of Flora at different ages, creating a multilayered portrayal of her life. "With a lyrical text, immersive staging and an enigmatic and compelling performance style, Wilson uses space and sound to create a warm but disorientating experience that grips the audience in Flora's fracture...
