Evidence about differences in processing speed (PS) performance between men and women with schizophrenia is inconclusive. Moreover, PS deconstruction into its subcomponents has not been compared among sexes. The aim of this study was to compare PS and its subcomponents (i.e., response processing – RP; accuracy – AC; and psychomotor speed - PmS) performance between men and women with schizophrenia and to explore its associations with clinical variables. Fiftysix patients (36 men, 20 women) were recruited. The PS domain tasks from the MATRICS Consensus Cognitive Battery were used. Women outperformed men in RP and AC but were slower in PmS. For men, correlations were found between functionality, RP and AC; age of onset was associated with AC; in women, illness duration and symptomatology correlated with AC. Sex-related differences regarding PS performance in schizophrenia resemble those observed in healthy individuals. Remediation strategies should consider sex differences in PS for more accurate interventions.

The review of the latest foreign literature on the issue of sex differences in ADHD carriers is presented. The analysis of theories on the causes of the prevalence of the disorder among boys and girls is presented, and minor sex differences are highlighted. Therefore, ADHD is more common among boys than among girls, which leads to arguments about the difference valid in the prevalence of the disorder among men and women. Also, many researchers have noticed certain differences in the symptoms and behaviour of girls compared to boys, both in childhood and adulthood. Boys and girls with ADHD appear to be more similar than different, and usually the symptoms are not sex specific, but still there is a difference. In general, these differences are manifested in the fact that girls have problems with the emotional sphere and the predominant inattentive symptoms of ADHD, while boys have problems with the behavioural sphere and the predominant impulsive and hyperactive type of ADHD. Moreover, boys are more aggressive in behaviour than girls, although girls are more likely to manifest verbal aggression than their female peers, who do not have the disorder. It has been found that the difference in the prevalence of the disorder among males and females can be described by the Cognitive Endophenotype Theory, which assumes the influence of generally accepted endophenotypes on the severity of ADHD, that means processing speed, inhibition and working memory. This theory does not preclude theories such as the Mean Difference Model and the Variance Difference Model, which state that men on the average have more severe symptoms than women, and thus the scale of the severity of the ADHD among boys is much wider than among women.

AbstractMovement disorders such as Parkinson's disease (PD), restless legs syndrome (RLS), chorea, essential tremor, and Tourette syndrome, occur in men and women of all ages. Yet, considerable sex differences in epidemiology, clinical features, and treatment exist in these disorders. In this review, we highlight key differences in the evaluation and management of women with movement disorders, addressing sex-specific complications of treatment and unique challenges surrounding the management of movement disorders during pregnancy. We review the complex relationship between estrogen and movement disorders, including the putative neuroprotective effects of estrogen in PD and the modulatory effects on RLS and chorea associated with autoimmune disease. Further understanding of sex-specific and hormonal effects on clinical features will be important to optimize the management of women with movement disorders in the future.

Blood Pressure Responses

Sex differences in cardiovascular reactivity to stress are well documented, with some studies showing women having greater heart rate responses than men, and men having greater blood pressure responses than women, while other studies show conflicting evidence. Few studies have attended to the gender relevance of tasks employed in these studies. This study investigated cardiovascular reactivity to two interpersonal stressors consistent with different gender roles to determine whether response differences exist between men and women. A total of 26 men and 31 women were assigned to either a traditional male-oriented task that involved interpersonal conflict (Conflict Task) or a traditional female-oriented task that involved comforting another person (Comfort Task). Results demonstrated that women exhibited greater heart rate reactions than men independent of the task type, and that men did not display a higher reactivity than women on any measure. These findings indicate that sex of participant was more important than gender relevance of the task in eliciting sex differences in cardiovascular responding.

Summary: The Gudjonsson Compliance Scale (GCS), the COPE Scale, and the Rosenberg Self-Esteem Scale were administered to 212 men and 212 women. Multiple regression of the test scores showed that low self-esteem and denial coping were the best predictors of compliance in both men and women. Significant sex differences emerged on all three scales, with women having lower self-esteem than men, being more compliant, and using different coping strategies when confronted with a stressful situation. The sex difference in compliance was mediated by differences in self-esteem between men and women.

Individual differences in time production should indicate differences in the rate of functioning of an internal clock, assuming the existence of such a clock. And sex differences in time production should reflect a difference in the rate of functioning of that clock between men and women. One way of approaching the data is to compute individual regressions of produced duration (P) on target duration (T), after log transformation, and to derive estimates for the intercept and the slope. One could investigate a sex difference by comparing these estimates for men and women; one could also contrast them by looking at mean log(P). Using such indices, we found a sex difference in time production, female participants having a relatively faster internal clock, making shorter time productions, and having a smaller exponent. The question is whether a sex difference in time production would be found using other methods for analyzing the data: (1) the P/T ratio; (2) an absolute discrepancy (|P-T|) score; and (3) an absolute error (|P-T|/T) score. For the P/T ratio, female participants have a lower mean ratio in comparison to the male participants. In contrast, the |P-T| and |P-T|/T indices seem to be seriously compromised by wide individual differences.

Beliefs and feelings about death are excerpted from interviews conducted with elderly English men and women, who were viewed as spiritually mature by those in their community. Respondents reported a wide range of beliefs about death, reflecting their personal experience, but none reported fear of death. Subtle sex differences were noted: men tended to picture death in spatial terms, of moving into a new dimension, while women tended to describe death in terms of relationships. Overall the respondents indicated that they placed a positive value on death, viewing it as a continuation of, and source of meaning for their present life.

Outcome Differences

Sex differences have been well identified in many brain tumors. Even though glioblastoma (GBM) is the most common primary malignant brain tumor in adults and has the worst outcome, well-established differences between men and women are limited to incidence and outcome. Little is known about sex differences in GBM at the disease phenotype and genetical/molecular level. This review focuses on a deep understanding of the pathophysiology of GBM, including hormones, metabolic pathways, the immune system, and molecular changes, along with differences between men and women and how these dimorphisms affect disease outcome. The information analyzed in this review shows a greater incidence and worse outcome in male patients with GBM compared with female patients. We highlight the protective role of estrogen and the upregulation of androgen receptors and testosterone having detrimental effects on GBM. Moreover, hormones and the immune system work in synergy to directly affect the GBM microenvironment. Genetic and molecular differences have also recently been identified. Specific genes and molecular pathways, either upregulated or downregulated depending on sex, could potentially directly dictate GBM outcome differences. It appears that sexual dimorphism in GBM affects patient outcome and requires an individualized approach to management considering the sex of the patient, especially in relation to differences at the molecular level.
