Cognitive self-consciousness, implicit learning and obsessive-compulsive disorder.

The negative appraisal of commonly experienced intrusive thoughts is posited to play an important role in obsessive-compulsive disorder (OCD), although why some people focus on thought experiences and have difficulties dismissing intrusions is not well understood. To elucidate how intrusive thoughts might become obsessional problems, relations between thought-focused attention (cognitive self-consciousness; CSC), implicit sequence learning and OCD were evaluated in individuals with OCD (n=43) and in a nonclinical comparison group (n=41). Impaired performance on a serial reaction time test, but enhanced recognition of the embedded stimulus pattern, was predicted for the OCD group based on hypothesized nonconscious processing differences. Predicted differences were found and CSC score predicted reaction time and pattern recognition. CSC might be a consequence of conscious processing gating problems that increase thought salience and the likelihood of the negative appraisal of intrusive thoughts. Implications for theory and treatment are discussed.

Screening for dementia in community-based memory clinics.

PROBLEM: Dementia is a significant public health problem that is underrecognized in primary care settings. This study examined the usefulness of 3 brief screening tests in detecting dementia and mild cognitive impairment (MCI) in persons seeking consultation for memory complaints within a network of memory diagnostic clinics in Wisconsin. METHODS: This prospective study of consecutive referrals for memory diagnostic evaluation analyzed data for 364 patients > or = 50 years. Scores on 3 cognitive screening measures-the Mini-Mental State Examination (MMSE), Clock Drawing, and Animal Naming--were compared to clinical diagnosis of normal cognitive aging, MCI, or dementia. RESULTS: Using the standard cut score of <24, the MMSE identified only 60% of persons diagnosed with dementia. By contrast, using a recommended cut score of <14 words per minute, Animal Naming identified 85% of persons with dementia with a relatively low (12%) false positive rate. Clock Drawing was intermediate to the other 2 measures in screening effectiveness. CONCLUSIONS: Animal Naming was moderately to highly effective in identifying dementia. The naming procedure is easy to administer and may have value as a brief initial dementia screen in busy practice settings. More demanding cognitive measures may be needed to improve screening accuracy for MCI.

Age-related functional recruitment for famous name recognition: an event-related fMRI study.

Recent neuroimaging research shows that older adults exhibit recruitment, or increased activation on various cognitive tasks. The current study evaluated whether a similar pattern also occurs in semantic memory by evaluating age-related differences during recognition of Recent (since the 1990s) and Enduring (1950s to present) famous names. Fifteen healthy older and 15 healthy younger adults performed the name recognition task with a high and comparable degree of accuracy, although older adults had slower reaction time in response to Recent famous names. Event-related functional MRI showed extensive networks of activation in the two groups including posterior cingulate, right hippocampus, temporal lobe and left prefrontal regions. The Recent condition produced more extensive activation than the Enduring condition. Older adults had more extensive and greater magnitude of activation in 15 of 20 regions, particularly for the Recent condition (15 of 15; 7 of 15 also differed for Enduring); young adults did not show greater activation magnitude in any region. There were no group differences for non-famous names, indicating that age differences are task-specific. The results support and extend the existing literature to semantic memory tasks, indicating that older adult brains use functional recruitment to support task performance, even when task performance accuracy is high.

Medical students' exposure to and attitudes about drug company interactions: a national survey.

CONTEXT: While exposure to and attitudes about drug company interactions among residents have been studied extensively, relatively little is known about relationships between drug companies and medical students. OBJECTIVE: To measure third-year medical students' exposure to and attitudes about drug company interactions. DESIGN, SETTING, AND PARTICIPANTS: In 2003, we distributed a 64-item anonymous survey to 1143 third-year students at 8 US medical schools, exploring their exposure and response to drug company interactions. The schools' characteristics included a wide spectrum of ownership types, National Institutes of Health funding, and geographic locations. In 2005, we conducted a national survey of student affairs deans to measure the prevalence of school-wide policies on drug company-medical student interactions. MAIN OUTCOME MEASURES: Monthly frequency of students' exposure to various activities and gifts during clerkships, and attitudes about receiving gifts. RESULTS: Overall response rate was 826/1143 (72.3%), with range among schools of 30.9%-90.7%. Mean exposure for each student was 1 gift or sponsored activity per week. Of respondents, 762/818 (93.2%) were asked or required by a physician to attend at least 1 sponsored lunch. Regarding attitudes, 556/808 (68.8%) believed gifts would not influence their practices and 464/804 (57.7%) believed gifts would not affect colleagues' practices. Of the students, 553/604 (80.3%) believed that they were entitled to gifts. Of 183 students who thought a gift valued at less than $50 was inappropriate, 158 (86.3%) had accepted one. The number of students who simultaneously believed that sponsored grand rounds are educationally helpful and are likely to be biased was 452/758 (59.6%). Students at 1 school who had attended a seminar about drug company-physician relationships were no more likely than the nonattending classmates to show skepticism. Of the respondents, 704/822 (85.6%) did not know if their school had a policy on these relationships. In a national survey of student affairs deans, among the 99 who knew their policy status, only 10 (10.1%) reported having school-wide policies about these interactions. CONCLUSIONS: Student experiences and attitudes suggest that as a group they are at risk for unrecognized influence by marketing efforts. Research should focus on evaluating methods to limit these experiences and affect the development of students' attitudes to ensure that physicians' decisions are based solely on helping each patient achieve the greatest possible benefit.

Medial temporal lobe activity for recognition of recent and remote famous names: an event-related fMRI study.

Previous neuroimaging studies examining recognition of famous faces have identified activation of an extensive bilateral neural network [Gorno Tempini, M. L., Price, C. J., Josephs, O., Vandenberghe, R., Cappa, S. F., Kapur, N. et al. (1998). The neural systems sustaining face and proper-name processing. Brain, 121, 2103-2118], including the medial temporal lobe (MTL) and specifically the hippocampal complex [Haist, F., Bowden, G. J., & Mao, H. (2001). Consolidation of human memory over decades revealed by functional magnetic resonance imaging. Nature Neuroscience, 4, 1139-1145; Leveroni, C. L., Seidenberg, M., Mayer, A. R., Mead, L. A., Binder, J. R., & Rao, S. M. (2000). Neural systems underlying the recognition of familiar and newly learned faces. Journal of Neuroscience, 20, 878-886]. One model of hippocampal functioning in autobiographical, episodic memory retrieval argues that the hippocampal complex remains active in retrieval tasks regardless of time or age of memory (multiple trace theory, MTT), whereas another proposal posits that the hippocampal complex plays a time-limited role in retrieval of autobiographical memories. The current event-related fMRI study focused on the medial temporal lobe and its response to recognition judgments of famous names from two distinct time epochs (1990s and 1950s) in 15 right-handed healthy older adults (mean age=70 years). A pilot study with an independent sample of young and older subjects ensured that the stimuli were representative of a recent and remote time period. Increased MR signal activity was observed on a bilateral basis for both the hippocampus and parahippocampal gyrus (PHG) during recognition of familiar names from both the recent and remote time periods when compared to non-famous names. However, the impulse response functions in the right hippocampus and right PHG demonstrated a differential response to stimuli from different time epochs, with the 1990s names showing the greatest MR signal intensity change, followed by the 1950s names, followed by foils. The finding that recognition of famous names produced significant bilateral MTL activation regardless of time epoch relative to foils provides support for the MTT model. However, the finding of a temporal gradient in the right MTL also provides support for the HC model, given the greater MTL response associated with recently famous names relative to remotely famous names.

Screening for major depression in epilepsy with common self-report depression inventories.

PURPOSE: Major depression is a common psychiatric comorbidity in chronic epilepsy that is frequently unrecognized and untreated. A variety of self-report mood inventories are available, but their validity as well as ability to detect major depression in epilepsy remains uncertain. The purpose of this study was to determine the ability of two common depressive symptom inventories to identify major depression in people with epilepsy. METHODS: In total, 174 adult patients with epilepsy underwent standardized psychiatric interview techniques [Mini International Neuropsychiatric Interview (MINI) and Mood Disorders module of the Structured Clinical Interview for DSM-IV Axis I Disorders-Research Version (SCID-I)] to determine the presence of current major depression. Subjects completed two self-report depression inventories [Beck Depression Inventory-II (BDI-II), Center for Epidemiological Study of Depression (CES-D)]. The ability of these self-report measures to identify major depression as identified by the gold standard structured interviews was examined by using diagnostic efficiency statistics. RESULTS: Both the BDI-II and the CES-D exhibited significant ability to identify major depression in epilepsy. All ROC analyses were highly significant (mean area under the curve, 0.92). Mean sensitivity (0.93) and specificity (0.81) were strong, with excellent negative predictive value (0.98) but lower positive predictive value (0.47). CONCLUSIONS: Common self-report depression measures can be used to screen for major depression in clinical settings. Use of these measures will assist in the clinical identification of patients with major depression so that treatment can be initiated.

Factors affecting medical student career choice of psychiatry from 1999 to 2001.

OBJECTIVE: The proportion of students matching into psychiatry (PMP) at each medical school results from a complex interplay between extrinsic (e.g., national trends, geographic region) and intrinsic factors (e.g., the quality of psychiatric education). The goal of the study was to learn the extent to which regional and local extrinsic factors (and one intrinsic factor) influenced PMP at medical schools in the U.S. from 1999 to 2001. METHODS: The authors obtained data about these factors from deans of student affairs, the National Resident Matching Program (NRMP), American Medical Association (AMA), Association of American Medical Colleges (AAMC), American Psychiatric Association (APA), and Harvard University's HealthSystem Consortium. RESULTS: The best predictor of a school's PMP is the PMP of the prior year for that particular school. Local and regional extrinsic factors were not significantly associated with PMP. There was a modest inverse correlation between PMP and the proportion of international medical graduates (IMGs) in psychiatry residency. CONCLUSIONS: The authors infer that intrinsic factors are most important for recruitment, and they make recommendations for addressing these factors.

Who seeks genetic susceptibility testing for Alzheimer's disease? Findings from a multisite, randomized clinical trial.

PURPOSE: Alzheimer's disease, for which one form of the apolipoprotein E (APOE) genotype is a risk factor, provides a paradigm in which to examine response to susceptibility testing for common, complex diseases. This study's main purposes were to estimate interest in such testing and to examine demographic predictors of study participation. METHODS: In this 3-site, randomized clinical trial (RCT), the intervention was a risk assessment program wherein genetic counselors educated adult children of AD patients about lifetime risk of disease based on their gender, family history, and APOE genotype. Two groups of participants were followed from initial contact to RCT enrollment: those who were systematically contacted through research registries, and those who were self-referred. RESULTS: Of 196 systematically contacted participants, 47, or 24%, progressed from initial contact to RCT enrollment. These participants were more likely to be below age 60 (adjusted OR = 3.83, P < 0.01) and college educated (adjusted OR = 3.48, P < 0.01). Of 179 self-referred participants, 115, or 64%, progressed from initial contact to RCT enrollment. Most self-referred participants had a college education and were female (79%). CONCLUSIONS: In the first RCT to examine genetic susceptibility testing for AD, uptake rates were sufficiently high to merit concern that future test demand may strain available education and counseling resources. Findings suggest that susceptibility testing for AD may be of particular interest to women, college educated persons, and persons below age 60.

Use of clerkship learning objectives by members of the Association of Directors of Medical Student Education in Psychiatry.

OBJECTIVE: The authors aimed to determine the extent and use of the 1995 psychiatry clerkship goals and objectives published by the Association of Directors of Medical Student Education in Psychiatry (ADMSEP) and to obtain members' guidance regarding their proposed revision. METHODS: ADMSEP members were surveyed regarding their awareness and current use of the objectives, their advantages and disadvantages, and suggestions for revision. RESULTS: Fifty-four of approximately 130 members returned surveys, including 60% of members who identified as clerkship directors. Ninety percent of respondents were aware of the objectives and 48% used them. Use was significantly related to years of ADMSEP membership. Those who used the objectives did so moderately or extensively, and 84% found them moderately to very useful. Reasons for nonuse were the employment of other objectives, unawareness of them, too lengthy/not user-friendly, and lack of resources to implement them. Comprehensiveness and specificity were cited as both their most useful aspects and their least useful aspects. The most frequently suggested revisions included prioritization, adding more clinical competencies, decreasing the total number, and developing supporting documents such as clinical cases, references, sample examinations, and a resource manual. Respondents held strongly favorable attitudes regarding the utility of learning objectives. CONCLUSION: The ADMSEP psychiatry clerkship learning objectives were widely but not uniformly used among members surveyed, and use is significantly related to years of membership. Respondents strongly favor using learning objectives and desire that a new iteration of the document be more user-friendly, oriented to competencies, and supported by resource materials.
