轻度认知功能障碍与颈动脉狭窄的相关性研究

为了探讨颈动脉狭窄与轻度认知功能障碍(MCI)的关系,选取轻度认知功能障碍病例89例,健康对照组100例,全部行颈动脉彩超检查及简易智能状态量表(MMSE),蒙特利尔认知量表(MoCA),临床痴呆量表(CDR),日常生活能力量表(ADL),汉密尔顿抑郁量表(HAMD)测评.结果发现轻度认知功能障碍组颈动脉狭窄发生率明显高于对照组,左侧发生率明显高于右侧.其中随着狭窄的严重程度增加,患者在延迟回忆、视空间与执行功能、计算力与注意力、语言能力方面评分显著下降.从这一结果可以看出轻度认知功能障碍与颈动脉狭窄密切相关.     

Presleep Suggestion Related to a Phobic Object: Successful Manipulation of Reported Dream Affect

Twenty-four female subjects with a strong dislike of snakes slept for four nonconsecutive nights in the laboratory. They were divided into four groups of six, each group receiving a different presleep suggestion on Nights 3 and 4. On Nights 2, 3, and 4, before sleep, the subjects saw but did not have to touch a live snake and their dreams were collected for each REM period. The results showed that, when compared with the subjects who received the negative affect suggestions, subjects who received positive affect suggestions had significantly higher levels of positive emotions in their dreams, rated their own dreams as more pleasant, and had significantly lower levels of anxiety, sadness, and aggression. These results support the hypothesis that presleep suggestion can be an effective technique in influencing the affective dimension of the dream.     

Exposure to Repetitive Tasks Induces Motor Changes Related to Skill Acquisition and Inflammation in Rats

The authors elucidate exposure-response relationships between repetitive tasks, inflammation, and motor changes with work-related musculoskeletal disorders. Using a rat model of reaching and handle pulling, they examined effects of performing a high-repetition, low-force (HRLF); low-repetition, high-force (LRHF); or high-repetition, high-force (HRHF) task (2 hr/day, 3 days/week, 12 weeks) on reach rate and force, percentage of successful reaches, duration of participation, and grip strength. Reach rate and reach force improved with HRLF, and percentage success increased in all groups in Week 9, and in HRLF and HRHF in Week 12, indicative of skill acquisition. Duration and grip strength showed force-dependent declines with task performance. A subset of HRHF rats received ibuprofen in Weeks 5–12. Ibuprofen significantly improved reach rate, reach force, and duration in treated rats, indicative of an inflammatory influence on reach performance. Ibuprofen improved percentage of successful reaches in Week 9, although this increase was not sustained. However, declines in grip strength, a nocifensive behavior, were not prevented by ibuprofen. Examination of cervical spinal cords of untreated and ibuprofen treated HRHF rats showed increased IL-1beta, an inflammatory cytokine, in neurons. These findings suggest that only a preventive intervention could have addressed all motor declines.     

False Memories in Individuals at Risk for Developing an Eating Disorder

In the present study, the authors used the Roediger and McDermott paradigm (H. L. Roediger & K. B. McDermott, 1995) to examine the creation of false memories in individuals at risk for developing an eating disorder. Thirty-three controls and 34 individuals at risk for eating disorders studied 6 word lists taken from the paradigm. Three lists were food related (bread, fruit, sweet), and 3 were not food related (king, doctor, black). Both groups produced false memories (i.e., recalled or recollected words that were not presented in the lists), and controls actually produced more false memories than the at-risk individuals produced in the recall of the food-related items. Groups did not differ in their recall of items not related to food.     

Occupational Therapy Intervention in the Treatment of Alcoholics

The first section of this article will provide the rationale for all occupational therapists to learn extensively about the isease of alcoholism regardless of area of practice or type of agency where employed. It will offer su estions on how this learning can take place. The second section will take an historic look at occupational therapy literature documenting the use of occupational therapy in alcoholism rehabilitation from 1941 to the present. It will describe modalities currently being used by occupational therapists in alcoholism rehabilitation and discuss expansion of occupational therapy in this practice area.     

Project ABLE

This paper describes a proposed model for the management of Army soldiers rendered ineffective due to inadequate skills in coping with life stress. The history of Army mental health programs is reviewed to establish the rationale for program development. The proposed treatment methods and staffing are discussed. The application of this peacetime treaetment model in the management of combat psychiatric casualties is presented. Emphasis is placed on the role of the Army occupational therapist as a professional skilled in the use of task-directed behavior to enhance daily living skills.     

Neuroticism,BIS, and reactivity to discrete negative mood inductions

Research has established relationships between the personality dimensions of neuroticism and BIS and broad negative emotional reactivity. However, few researchers have examined the relationships among neuroticism, BIS, and discrete negative emotional reactivities. The present study examined whether individuals scoring high on neuroticism and BIS were more reactive across four discrete negative mood inductions, relative to those scoring low on these traits. Participants (n = 166) completed personality questionnaires, measures of current mood, viewed a specific mood-inducing film clip (sadness, anger, fear or disgust) and then reported their moods a second time. Results revealed that neuroticism/BIS was associated with high reactivity to the fear and sadness inductions. Neuroticism/BIS did not predict anger or disgust reactivity, but neuroticism/BIS and extraversion/BAS interacted in predicting anger. Although further research is needed to extend generalizability, it appears that neuroticism and BIS predict negative emotional reactivity broadly, but not ubiquitously.
