Alzheimer's disease is a progressive condition that results in brain wasting and eventual death. With its increasing diagnosis rate, counselors will likely acquire clients with Alzheimer's disease or their caregivers. Important background information and several practical counseling methods are provided that may assist counselors working with this population. 相似文献

The mammalian tachykinins are a family of closely related peptides including substance P, neurokinin A, neurokinin B and, recently, also hemokinin-1. They are present in the peripheral and central nervous systems, and bind to three known neurokinin (NK) receptors, the NK(1)-, NK(2)- and NK(3) receptors. In both rodents and humans, NK(3) receptors are expressed in brain structures which have been associated with learning and memory. Evidence for a role of NK(3) receptors in learning and memory has been found in NK(3) receptor knockout mice. Here, we investigated the influence of the NK(3) receptor agonist, senktide (0.1, 0.2 and 0.4 mg/kg), on the performance of C57BL/6 mice in a recently developed episodic-like memory task. Since a promnestic effect of senktide was expected, we employed an experimental protocol that provided sub-optimal learning conditions for episodic-like memory. The results indicate that senktide promotes episodic-like memory in mice in a dose-dependent manner, providing, for the first time, evidence for an involvement of NK(3) receptors in episodic-like memory. 相似文献

The triarchic model of psychopathy encompasses different conceptions of psychopathic personality characterized by three phenotypic components: boldness, disinhibition, and meanness. Psychopathy is a complex construct at both emotional and behavioral level. The aim of this study was to determine the core elements of psychopathic personality in a community sample and analyze the relation between these elements and other personality traits such as aggression, and certain specific behavioral manifestations such as substance use. The study sample comprised 1,159 participants aged between 17 and 74 years, who were administered the Triarchic Psychopathy Questionnaire, the Impulsive‐Premeditated Aggression Scale, and the Aggression Questionnaire. The results show that the constructs of meanness and disinhibition are more highly associated with different forms of both impulsive and premeditated aggression. Furthermore, men scored higher on all three components of the triarchic model compared to women. Finally, higher substance use (tobacco and drugs) was associated with higher scores in meanness, boldness, and disinhibition. These findings demonstrate the importance of assessing psychopathy in a community sample, and the detection of possible risk factors for the disorder. 相似文献

Acquired behavioral changes have essentially been described in advanced multiple sclerosis (MS). The present study was designed to determine whether behavioral modifications specifically related to the MS pathological process could be identified in the initial phase of the disease, as compared to control patients with chronic, relapsing and progressive inflammatory disorders not involving the central nervous system (CNS). Eighty-eight early MS patients (Expanded Disability Status Scale score 相似文献

Presymptomatic testing for spinocerebellar ataxia type 2 (SCA2) in Cuba started five years ago. We have now investigated the
psychological impact of test results on 150 individuals at 50% risk for SCA2. In a prospective study, psychological instruments
were used to evaluate depression, anxiety and family functioning (1) before testing and (2) one year after disclosure of the
test result. One year after, anxiety and depression levels decreased both in carriers and non-carriers, but anxiety decreased
significantly more in carriers. Pathological levels of anxiety were seen mostly in members of dysfunctional families, but
decreased more in them than in other consultands. Presymptomatic testing thus seems to have been especially beneficial for
these testees, possibly due to a greater gain from the psychosocial support received. It would be pertinent to evaluate now
the impact of other psychosocial variables and perform longer-term longitudinal studies. 相似文献

The importance of optimal visual function in demanding interceptive tasks is far from established. The aim of the study was to determine whether induced myopic blur and hence sub-optimal visual function would give rise to a detrimental effect on performance in the execution of an interceptive task. The batting performance of grade level cricket players was assessed facing a bowling machine whilst wearing contact lenses of four different refractive conditions (plano (nil), +1.00, +2.00 and +3.00D over-refraction), inducing increasing amounts of myopic blur. Performance for each condition was assessed based both on the shot quality against each delivery judged by a qualified cricket coach blind to each condition, along with an evaluation of the quality of ball-bat contact for each delivery. No significant change was found in batting performance with the introduction of +1.00 and +2.00D of induced myopic blur. A +3.00D over-correction was required before any significant decrease in batting performance was detected, demonstrating that batters needed to be essentially legally blind (as simulated through the use of the +3.00D over-refraction) before there was any significant measurable decrement in batting performance. We concluded that optimal visual correction is not necessarily required for optimal performance in a demanding interceptive task, and that the human perceptual-motor system is capable of compensating for marked alterations in input. 相似文献

The association among items of the self-reported version of the Hamilton Depression Scale (Carroll Rating Scale), answered according to a memory of a maximally disturbing event experienced, and respondents' sex was examined in a nonclinical sample of 320 college students, 164 women (M age=21.7 yr., SD=3.6) and 156 men (M age=23.5 yr., SD=5.8). An assessment of sex bias was also evaluated. Multiple regression analysis showed that statements regarding unhappiness, urge to cry, dizziness and faintness, and waking in the middle of the night were significantly associated with women. Removal of these items from the Carroll Rating Scale Total scores eliminated the sex differences in depression rates. Items that displayed significant sex bias were those regarding behavior and emotions commonly attributed to women within the general population. 相似文献

We studied the effects of delayed constructed-response identity matching on spelling with 6 first graders with histories of school failure. After training, the children learned to spell words to dictation and their cursive writing improved. These results replicate studies showing that delayed constructed-response matching establishes spelling. For 2 children, spelling of generalization words--words formed by recombining the syllables of training words--also improved. These results extend studies that have shown recombinative generalization in reading and spelling. 相似文献

The goal of the present study was to compare the relative distress of homosexual and heterosexual Brazilian men and women on scenarios in which they imagined their partners sexually or emotionally involved with another person, using a forced-choice paradigm and continuous measures. Participants were 68 heterosexual men, 72 heterosexual women, 42 homosexual men, and 35 homosexual women. On the forced-choice questions heterosexual men (39 on one question and 37 on the other) were more upset than their female counterparts (21 on one question and 15 on the other) by scenarios of sexual infidelity than those of emotional infidelity. On questions using continuous measures no significant difference was found between pleasurable sex and attachment scenarios for heterosexual women or heterosexual men. On the highly upsetting scenarios heterosexual men discriminated between flirting and both pleasurable sex and attachment scenarios, being less disturbed by the former. In contrast, heterosexual women were equally distressed by the three scenarios. Scores for the homosexual men and homosexual women fell in between those of the heterosexual men and heterosexual women and did not show a clear cut preference for the sexual infidelity or the emotional alternative on the forced-choice paradigm. However, on the continuous measures of jealousy homosexuals resembled heterosexuals of the opposite sex. There was no evidence that jealousy would be less intense among homosexuals although reproductive outcomes were not at risk. 相似文献
