Bridging cognitive screening tests in neurologic disorders: A crosswalk between the short Montreal Cognitive Assessment and Mini-Mental State Examination.

INTRODUCTION: To provide a crosswalk between the recently proposed short Montreal Cognitive Assessment (s-MoCA) and Mini-Mental State Examination (MMSE) within a clinical cohort. METHODS: A total of 791 participants, with and without neurologic conditions, received both the MMSE and the MoCA at the same visit. s-MoCA scores were calculated and equipercentile equating was used to create a crosswalk between the s-MoCA and MMSE. RESULTS: As expected, s-MoCA scores were highly correlated (Pearson r = 0.82, P < .001) with MMSE scores. s-MoCA scores correctly classified 85% of healthy older adults and 91% of individuals with neurologic conditions that impair cognition. In addition, we provide an easy to use table that enables the conversion of s-MoCA score to MMSE score. DISCUSSION: The s-MoCA is quick to administer, provides high sensitivity and specificity for cognitive impairment, and now can be compared directly with the MMSE.

Revised Medical Criteria for Evaluating Neurological Disorders. Final rule.

We are revising the criteria in the Listing of Impairments (listings) that we use to evaluate disability claims involving neurological disorders in adults and children under titles II and XVI of the Social Security Act (Act). These revisions reflect our program experience; advances in medical knowledge, treatment, and methods of evaluating neurological disorders; comments we received from medical experts and the public at an outreach policy conference; responses to an advance notice of proposed rulemaking (ANPRM); and public comments we received in response to a Notice of Proposed Rulemaking (NPRM) and a Federal Register notice that reopened the NPRM comment period.

Measuring complexity in neurological rehabilitation: the Oxford Case Complexity Assessment Measure (OCCAM).

OBJECTIVE: To investigate validity and reliability of a new measure of case complexity, the Oxford Case Complexity Assessment Measure (OCCAM). DESIGN: Data collection on inpatients and outpatients attending for rehabilitation. In subsets, repeat assessments were undertaken two weeks apart, by clinicians unaware of initial data, and on admission and on discharge from inpatient rehabilitation. SETTING: Specialist neurological rehabilitation service. SUBJECTS: Patients receiving rehabilitation after acute onset disability. INTERVENTIONS: Assessment by clinical staff as part of routine care. MEASURES: OCCAM, the INTERMED, Rehabilitation Complexity Scale - Extended (RCS-E), clinical judgement of complexity (0-10 numerical rating scale), length of stay and discharge destination (for inpatients). RESULTS: For the OCCAM, the Cronbach's α coefficient was 0.69 and item-total correlations were moderate to high except for pathology and time. The correlation coefficients with OCCAM were: INTERMED (ρ = 0.694), RCS-E (ρ = 0.736), and team judgement (ρ = 0.796). Inter-rater agreement was excellent (Weighted κ = 0.95). Correlation between admission and discharge scores was ρ = 0.917. Test-retest agreement was good (intraclass correlation coefficient 0.86). Higher mean admission scores were associated with prolonged stays (38.6 ± 12.2 versus 32.9 ± 13.7, P = 0.04) and failure to return home (48.0 ± 13.7 versus mean 32.1 ± 10.7, P < 0.001). The optimal cut-off of OCCAM to detect patients not discharged home was ≥ 34, with corresponding sensitivity and specificity of 84.6% and 62.8%, respectively. CONCLUSIONS: This preliminary evidence suggests that the OCCAM may measure case complexity reliably, and may predict rehabilitation resource used and outcome. Further research is warranted.

Neurological aspects of neglected tropical diseases: an unrecognized burden.

Neglected tropical diseases are a group of mostly infectious diseases that thrive among poor populations in tropical countries. A significant proportion of the conditions affecting the neurological system in such countries can be attributed to neglected tropical diseases of helminth, protozoan, bacterial, or viral origin. The neurological burden of neglected tropical diseases has not been thoroughly investigated yet, but is expected to be significant; its full appreciation, estimation, and recognition present significant challenges, as shown by the case of the "silent epidemic" of epilepsy. While tropical infections involving the nervous system are today largely preventable or treatable, as vaccines or chemotherapeutic agents are available to kill or neutralize the responsible agents, associated morbidity - when established - cannot be cured. In resource-poor settings it is likely that many infections will not be treated and will therefore progress into their advanced and severe stages, thus being increasingly associated with irreversible morbidity; this is also the case for neurological morbidity, which often entails permanent disability. Public health should aim at reducing the burden of tropical neurological diseases through interventions addressing the infection, the associated morbidity, and the disability deriving from it.

[Potentially addictive drugs on reimbursable prescription for chronic severe pain]. / Potensielt vanedannende legemidler på blåresept ved kroniske sterke smerter.

BACKGROUND: Changes in the Norwegian drug reimbursement system in 2008 included the establishment of a new reimbursement code (-71) which authorises coverage of expenditures for potentially addictive drugs in patients with severe, predominantly non-malignant, chronic pain. This reform has hitherto not been evaluated. MATERIAL AND METHOD: We assessed national data on drug reimbursements in accordance with code -71 for the period 2008-2011, and anonymised copies of all confirmation letters granting reimbursements according to code -71 in Central Norway (three counties) for 2010. Approximately 1300 individual applicants' gender and age, diagnosis, potentially addictive drug applied for, drug dose, and identity and specialty of the prescribing physician, were recorded. RESULTS: From the time of establishment, reimbursement code -71 has been utilised by an increasing number of individuals, encompassing close to 10,000 subjects in 3rd quarter 2011. Almost one-third of the approved applications were for pregabalin, and the rest were for various opioids. The diagnoses were most often derived from the musculoskeletal and nervous systems, and were often nonspecific. A considerable number of treatment regimens were not in accordance with current principles for the management of chronic non-malignant pain, and drug doses were at times remarkably high. INTERPRETATION: Aspects of this drug reimbursement regulation should be closely monitored, and may be in need of changes.

Child neurology practice and neurological disorders in East Africa.

Neurological disorders, including neurodevelopmental disorders, have been identified by the World Health Organization (WHO) as one of the greatest threats to global public health. It is generally believed that these conditions are more prevalent in the developing than the developed world because of multiple known risk factors such as infections, malnutrition, and limited resources for obstetric and neonatal management. In East Africa, few investigations have been conducted to obtain data on the magnitude and description of neurological disorders among children, and the practice of child neurology is faced with challenges cutting across areas of health personnel, patient diagnosis, management, and rehabilitation. This article reviews the burden, types, and causes of neurological disorders in the East African region. The challenges and successes in the practice of child neurology and recommendations for the future are discussed.

Assessment scale of the oral motor performance of children and adolescents with neurological damages.

Among the conditions that classify individuals as special needs patients are those resulting from neurological sequelae, particularly cerebral palsy (CP), which is a disorder of high prevalence. Innumerable alterations can be found in individuals with CP but the inability to control striated muscles, due to damages suffered by the central nervous system, should be emphasized. Changes in tonus, speed and strength of oral muscles, reduction of mandibular mobility amplitude and difficulty to passively seal the lips are characteristics observed in such individuals. Categorization of the individual's mastication pattern is important in order to establish diagnosis and treatment protocols and prognosis. The aim of this study was to develop an Oral Motor Assessment Scale (OMAS) and evaluate its performance in terms of construct validity and reliability in a cohort of 53 children and individuals with CP. Two dentists examined the same patients on two different occasions. Good interexaminer (kappa > 0.85) and intra-examiner (kappa > 0.90) agreement was obtained for the majority of the OMAS items. This study shows that the OMAS is an accurate and valid method of assessment of oral motor skills in children and adolescents with neurological damages.

[Coding in neuropediatrics based on the International Classification Diseases, 9th revision (ICD-9), 5th edition (2006)]. / Codificación en neurología pediátrica basada en la Clasificación Internacional de Enfermedades, 9.(a) revisión (CIE-9), 5.(a) edición (2006).

AIMS: To analyze International Classification Diseases, 9th revision (ICD-9) coding and adapt it, on a consensus basis, to 'reasons for medical consultation', 'diagnoses' and 'procedures' in child neurology. MATERIALS AND METHODS: The most frequent reasons for medical consultation, diagnoses and procedures in neuropediatrics were selected and assigned the most appropriate ICD-9, Clinical Modification (5th ed.) (ICD-9-CM) codes in accordance with this system's coding rules. Disorders were grouped by sections, and allocated to the various members of the working group (13 child neurologists from 10 hospitals in Madrid and environs). RESULTS: Available on the web www.neurologia.com/cie-9. ICD-9-CM codes were assigned to: 158 reasons for medical consultation; 886 diagnoses; 73 diagnostic procedures; and 53 therapeutic procedures. In every case, the most appropriate ICD-9 code was sought for the respective diagnosis. No codes were invented but the working group did take certain liberties with interpretation, which nevertheless showed respect for general ICD-9-CM philosophy and are described in full in the text. CONCLUSIONS: The creation of this ICD-9 adaptation will not only enhance diagnostic coding in child neurology departments, but will also provide them with a useful tool for setting up databases to enable information to be retrospectively analyzed and shared by the different health centers.

Care burden and depression in caregivers caring for patients with intractable neurological diseases at home in Japan.

OBJECTIVES: The aims of this study are to describe the care burden on caregivers of individuals with intractable neurological diseases and to clarify the prevalence of depression in caregivers and factors related to the presence of depression. METHODS: A cross-sectional survey was conducted among caregivers who provide home care to patients with neurological diseases such as Parkinson disease (PD), spinocerebellar degeneration (SCD), multiple system atrophy (MSA), and amyotrophic lateral sclerosis (ALS), using a mailed, self-administered questionnaire. We used the Burden Index of Caregivers to measure multi-dimensional care burden and the Center for Epidemiologic Studies Depression scale to determine the presence of depression among caregivers. RESULTS: A total of 418 questionnaires were analyzed. Although several domains of care burden for caregivers were significantly different among the four diseases, the intensity of caregiving and hours spent caregiving were the main definitive variables. In addition, we described different aspects of the care burden using the multi-dimensional care burden scale. The prevalence of depression in caregivers was high (PD, 46%; SCD, 42%; MSA, 63%; ALS, 61%). Hours required for close supervision of the patient (P=0.015), intensity of caregiving (P=0.024), and low household income (P=0.013) were independently-related variables for depression in caregivers. CONCLUSIONS: The care burden of caregivers was mainly explained by the intensity of caregiving and hours spent caregiving per day, not only according to the disease. The high prevalence of depression indicates the need for effective interventions, especially for caregivers of patients with MSA and ALS.

Access to special care dentistry, part 2. Communication.

This article considers what communication is, its elements, what helps and what hinders it, and why it matters. It also considers managing people with communication differences and when communication is affected in special care dentistry (SCD). The article focuses on patients with hearing and visual impairments and considers how communication is affected and what techniques can be used to improve the situation. It offers recommendations for communicating with patients with neurological impairments typically seen after stroke, such as aphasia and dysarthria, with tips for the listener including the use of communication aids where appropriate. Finally it will consider communicating with patients who have autistic spectrum conditions and discuss how effective techniques and a tailored approach to their specific needs and anxieties can increase the likelihood of a successful dental visit.

Frequency of abnormal scores on the Neuropsychological Assessment Battery Screening Module (S-NAB) in a mixed neurological sample.

The Neuropsychological Assessment Battery (NAB; Stern & White, 2003; White & Stern, 2003) is a comprehensive, modular battery of tests comprised of the following six modules: (a) Screening, (b) Attention, (c) Language, (d) Memory, (e) Spatial, and (f) Executive Functions. The Screening Module is an abbreviated version of the full NAB. The purpose of this descriptive study was to present index and primary test score information for the Screening Module in a mixed sample of patients with known neurological conditions. Participants were 37 outpatients with clear evidence of neurological damage or disease. Performance decrements were found on the Attention Index, most notably on the Numbers and Letters tests. Decrements were also found on the Executive Functions Index, most notably on the Word Generation test. Somewhat surprisingly, patients performed well across most of the individual test scores. This mixed clinical sample showed less neuropsychological compromise than the clinical samples presented in the NAB manual.

Validation of the Burden Index of Caregivers (BIC), a multidimensional short care burden scale from Japan.

BACKGROUND: We constructed a concise multidimensional care burden scale that reflects circumstances unique to Japan, with a focus on intractable neurological diseases. We surveyed 646 family caregivers of patients with intractable neurological diseases or stroke using 28 preliminary care burden scale items obtained from qualitative research. The results were used to finalize the feeling of care burden scale (BIC: burden index of caregivers), and verify its reliability and validity. METHODS: The survey was conducted among caregivers providing home health care to patients with intractable neurological diseases (PD [Parkinson's disease], SCD [spinocerebellar degeneration], MSA [multiple system atrophy], and ALS [amyotrophic lateral sclerosis]) or CVA (cerebrovascular accident) using a mailed, self-administered questionnaire between November, 2003 and May, 2004. RESULTS: Response rates for neurological and CVA caregivers were 50% and 67%, respectively, or 646 in total (PD, 279; SCD, 78; MSA, 39; ALS, 30; and CVA, 220). Item and exploratory factor analyses led to a reduction to 11 items, comprising 10 items from the 5 domains of time-dependent burden, emotional burden, existential burden, physical burden, and service-related burden; and 1 item on total burden. Examination of validity showed a moderate correlation between each domain of the BIC and the SF-8 (Health related quality of life scale, Short Form-8), while the correlation coefficient of the overall BIC and CES-D was 0.62. Correlation between the BIC and ZBI, a preexisting care burden scale, was high (r = 0.84), while that with the time spent on providing care was 0.47. The ICC (Intraclass correlation coefficient) by test-retest reliability was 0.83, and 0.68 to 0.80 by individual domain. CONCLUSION: These results show that the BIC, a new care burden scale comprising 11 items, is highly reliable and valid.

[Diagnosis versus code]. / Diagnose versus kode.

BACKGROUND: As a result of information about coding practice in a regional hospital, the Norwegian Board of Health carried out a special supervision of ear, nose and throat (ENT) departments and neurological departments during the autumn of 2003 and the spring of 2004. The aim was to investigate whether there was accordance between information in the patient records and the chosen diagnoses and codes. MATERIAL AND METHOD: Three hospitals were examined. Information in 100 selected patient records from each department was compared with diagnoses and codes. The codes reported to the Norwegian Patient Register (NPR) from two hospitals were compared with codes in the patient records. RESULTS: Incorrect diagnoses had been systematically recorded in one ENT department. Incorrect codes had been recorded in all the departments, especially the neurological departments. Many inconsistencies between codes in the patient records and those reported to NPR were found. INTERPRETATION: Wrong diagnoses were seldom made, but many diagnoses were unprecise because only ICD-10 diagnoses were used. The rules of coding hospital stays were frequently not used. Many of the codes reported to NPR had been altered, without medical basis and without being noted in the patients' records.

Medicolegal aspects of neurodiagnostic tests.

Legal issues that may arise in neurodiagnostic testing are reviewed briefly. This article focuses on applications of medical malpractice law with respect to negligence in selection, conduct, and interpretation of tests. The impact of the doctrine of informed consent is considered both in the context of malpractice law and human subjects research. The article concludes with a short exposition on enterprise liability and diagnostic tests, indicating the ways in which the growing role of corporations in medical practice may prompt changes in how claims for test-related medical injuries are processed. This article aims to convey an appreciation of how the law attempts to reduce test-related harms by imposing liability on individuals and organizations.
