The Relationship Between Personality and Neurocognition Among the American Elderly: An Epidemiologic Study.

BACKGROUND: Although different personality traits have often been associated with different levels of mental activity and cognitive functioning, no previous studies have evaluated the association in a sample that mirrors a nationally-representative sample of elderly individuals. OBJECTIVE: To evaluate the association between personality traits and neurocognitive functioning among individuals 51 years and older using the Cognition and Aging in the USA (CogUSA) database. METHODS: We analyzed the association between personality traits and neurocognitive scores derived from Waves I and II of the study. Neurocognitive functions were modeled as an outcome variable using the Big Five Personality Traits as predictors. RESULTS: All personality traits were associated with higher education except Conscientiousness. Older age was associated with higher levels of the Agreeableness and Openness traits. Extraversion, Conscientiousness and Openness were positively associated with increased neurocognitive function and self-rated present memory. Extraversion and Openness also had a positive association with long-term retrieval. Agreeableness was negatively associated with several neurocognitive functions, while Neuroticism was negatively associated with memory and cognitive effort. CONCLUSION: Extraversion, Conscientiousness and Openness personality traits are associated with good cognitive health. Individuals scoring high in Neuroticism and Agreeableness might benefit from tailored cognitive interventions to prevent age-related cognitive decline.

[Dissociative phenomena in a sample of outpatients]. / Fenomeni dissociativi in un campione di pazienti ambulatoriali.

AIM: The study describes the frequency and the quality of dissociative phenomena and their relationship with axis I disorders and the psychopathological severity in outpatients. METHODS: The sample (N=383) was subjected to MINI diagnostic interview and self-assessment scales DES and SCL-90. The data were analysed using SPSS. RESULTS: The 11,0% of subjects has a score ≥20 on DES. The 5,2% has no dissociative symptoms. The absorption images is the most frequent dissociative phenomenon, the less common is the dissociation amnesia. A relationship between dissociative phenomena and conditions unemployment, marital separation and single parties and an inverse relationship with age founded. Dissociative phenomena are more frequent in participants who have been diagnosed at least one axis I disorder and their severity is positively correlated with the number of diagnosed diseases and scores to the General Symptomatic Index. DISCUSSION: Our results point towards the existence of three types of dissociative experiences. The first type, represented by the factor absorption/imaginative involvement, is expressed along a continuum from normal to pathological; a second type, represented by the factor depersonalization/derealization, occurs in a significantly more intense and specific among subjects with axis I disorders; the latest manifestation dissociative, described by the dissociation amnesia, seems to have a predominantly typological feature that qualifies it as an experience not commonly distributed in the general population. The identifying of dissociative symptoms is necessary for the psychopathologic evaluation and to improve the effectiveness of treatment programs.

Keep moving without hurting: The interaction between physical activity and pain in determining cognitive function at the population level.

BACKGROUND: A number of studies have evaluated the association between cognitive function, pain, and physical activity. To our knowledge, however, no previous studies have evaluated these factors at the population level. AIMS: To evaluate the association between cognitive function in the elderly with pain, physical activity, and the interaction between these variables. Estimates are generated for the United States population. METHODS: We made use of the NHANES database (1999-2002), making adjustments so that our results represent the United States population. Cognitive function was evaluated through the Digit Symbol Substitution Test. Our main predictors were (1) pain, defined as soreness of either the shoulder, neck, lower back and joint, or a severe headache (2) physical activity, measured as the performance while performing tasks at home, physical activity intensity, walking, bicycle riding, and muscle strengthening. RESULTS: Most individual pain sites were not significantly associated with cognitive function, while all physical activity factors were associated with an increase in cognitive function. When evaluating the sample subset of those with cognitive scores lower than the median, a combination of more pain and less physical activity was consistently associated with lower cognitive scores when compared to those performing more physical activity with or without pain. When evaluating individuals with cognitive scores above the median, a similar association pattern was perceived. CONCLUSIONS: Among the population of individuals above the age of 60, higher cognitive levels are associated with more physical activity and less with pain, although both factors might impact cognition. Public policy resources should be commensurate with these findings when targeting cognitive function among the aging population.

[Causes and psychosocial consequences of schizophrenia: opinions of mental health personnel]. / Cause e conseguenze psicosociali della schizofrenia: le opinioni degli operatori dei SSM.

OBJECTIVE: Description of the opinions about causes and psychosocial consequences of schizophrenia in a sample of psychiatric professionals, recruited in 29 Italian Mental Health Centres (MHC). DESIGN: Each professional was asked to read a case-vignette describing a patient who met the ICD-10 criteria for schizophrenia. Referring to case-vignette, he/she was asked to fill the Questionnaire on the Opinions about Mental Illness--Professionals' version (QO-P). Professionals' opinions were explored in relation to: a) their socio-demographic variables and professional background; b) geographic location of the MHC. SETTING: 29 MHC stratified by geographic area (Northern, Central, Southern Italy) and population density of their catchment areas (> 100,000 inhabitants; between 100,000 and 25,000 inhabitants; < 25,000 inhabitants) and randomly selected. RESULTS: Data on 465 professionals were collected. 75% of the sample identified in the vignette a case of schizophrenia, 22% of depression/anxiety disorder. Factors most frequently mentioned as causes of the detected disorder were heredity (68%), stress (61%), family difficulties (46%). More pessimistic opinions about psychosocial consequences of schizophrenia were found among nurses and among professionals of Southern Italy, among those with lower educational level, older age and among those working longer in psychiatry. No statistical difference in the opinions about psychosocial consequences of schizophrenia was found among staff who referred the case-vignette to schizophrenia and those who did not. CONCLUSIONS: The results of this study outline the need to: a) include issues such as disability and psychosocial consequences of mental disorders in the basic training of professionals; b) increase the number of professionals trained in evidence-based psychosocial interventions.
