Gender differences in the treatment of patients with borderline personality disorder.

It is debated whether men with borderline personality disorder (BPD) are less often treated for their disorder, compared to women, even when they have sought care. Here, the aim was to examine gender differences in the treatment of patients with BPD. Through linkage to Swedish health and administrative registers, we identified all patients diagnosed with BPD (n = 5530) in Stockholm County from 2012 to 2016. We ascertained information on sociodemographic characteristics, comorbid psychiatric diagnoses, and all mental health care utilization within inpatient and outpatient mental health care, including receipt of psychiatric medication and various psychological therapies. We identified 802 men and 4,728 women with BPD during the study period. Men with BPD were less likely than their female counterparts to be treated with psychotherapy as well as psychiatric medication. Most of the differences in treatment with psychological therapies were nonsignificant in the multivariate model, indicating they are likely the result of differences in sociodemographic variables and comorbidity between men and women with BPD. Men with BPD were in average 4 years older than women at the time of the first BPD diagnosis, had lower education, and were also more likely to receive social welfare support. In conclusion, few men are diagnosed with BPD and those who are diagnosed are likely to receive somewhat less psychiatric medication and psychological therapies compared to women. Researchers and clinicians need to focus more on men with BPD to improve help-seeking and recognition of this disabling condition in men and enable equal treatment.

Core executive functions are associated with success in young elite soccer players.

Physical capacity and coordination cannot alone predict success in team sports such as soccer. Instead, more focus has been directed towards the importance of cognitive abilities, and it has been suggested that executive functions (EF) are fundamentally important for success in soccer. However, executive functions are going through a steep development from adolescence to adulthood. Moreover, more complex EF involving manipulation of information (higher level EF) develop later than simple executive functions such as those linked to simple working memory capacity (Core EF). The link between EF and success in young soccer players is therefore not obvious. In the present study we investigated whether EF are associated with success in soccer in young elite soccer players. We performed tests measuring core EF (a demanding working memory task involving a variable n-back task; dWM) and higher level EF (Design Fluency test; DF). Color-Word Interference Test and Trail Making Test were performed on an exploratory level as they contain a linguistic element. The lower level EF test (dWM) was taken from CogStateSport computerized concussion testing and the higher level EF test (DF) was from Delis-Kaplan Executive Function System test battery (D-KEFS). In a group of young elite soccer players (n = 30; aged 12-19 years) we show that they perform better than the norm in both the dWM (+0.49 SD) and DF (+0.86 SD). Moreover, we could show that both dWM and DF correlate with the number of goals the players perform during the season. The effect was more prominent for dWM (r = 0.437) than for DF (r = 0.349), but strongest for a combined measurement (r = 0.550). The effect was still present when we controlled for intelligence, length and age in a partial correlation analysis. Thus, our study suggests that both core and higher level EF may predict success in soccer also in young players.

Event related potential and response time give evidence for a physiological reserve in cognitive functioning in relapsing-remitting multiple sclerosis.

Cognitive dysfunction is common in multiple sclerosis (MS). Different factors may moderate the degree of cognitive deficit. The aim of the present study was to distinguish different mechanisms for cognitive reserve in relapsing-remitting MS (RRMS). The effects of clinical variables (physical disability, depression), premorbid intelligence (years of education, vocabulary knowledge), visual event-related potential measures (P300) and response time (RT) were studied in RRMS patients (n=71) and healthy subjects (n=89). Patients with high P300 amplitude and short RT had better cognitive performance. This effect was significantly weaker in controls. High P300 and short RT may be physiological markers of a cognitive reserve in RRMS. In contrast, the association between cognitive scores and premorbid intelligence was similar in patients and in control subjects. The effects of physiological reserve and clinical variables were studied in a hierarchical linear regression model of cognitive performance in RRMS. P300 amplitude and RT explained a considerable amount of variance in global cognitive performance (34%, p<0.001). The effects of P300 and RT were not moderated by premorbid intelligence. Physical disability and depression added significantly to explained variance, and the final model accounted for 44% (p<0.001) of the variation. We conclude that physiological reserve is the strongest moderator of cognitive impairment in RRMS.

P300 amplitude and response speed relate to preserved cognitive function in relapsing-remitting multiple sclerosis.

OBJECTIVE: To explore if cognitive impairment in relapsing-remitting multiple sclerosis (RRMS) is associated with abnormal neural function and if there is evidence of neural compensatory mechanisms. METHODS: Seventy-two RRMS patients and 89 healthy control subjects were included in a cross-sectional study. Event-related brain potential (P300) and response time (RT) were recorded with visual and auditory choice reaction tasks. Cognitive function was evaluated with an 18 item test battery. RESULTS: Patients had a decrease in cognitive function (p<0.001 for global score) and increased visual P300 amplitude frontally. P300 amplitude was normal in other brain areas and RT was normal. P300 latency was normal except for an increase in auditory latency occipitally. Cognitive performance correlated positively with parietal P300 amplitude in patients but not in controls. Cognition had stronger correlation (negative) with RT in patients than in controls. CONCLUSIONS: Patients with low P300 amplitude and long RT were more often cognitively impaired. This indicates that general factors such as signal amplitude and speed are limiting for cognitive function in RRMS patients. The increase in frontal P300 amplitude may be a compensatory effect. SIGNIFICANCE: Our findings suggest that high amplitude and fast speed may be protective against cognitive impairment.

Cognitive impairment has a strong relation to nonsomatic symptoms of depression in relapsing-remitting multiple sclerosis.

It is unclear how cognitive impairment in multiple sclerosis (MS) is influenced by physical disability, fatigue, and depression. Our aim was to identify the strongest clinical predictors for cognitive impairment in relapsing-remitting MS (RRMS) patients. The clinical risk factors included in the analysis were physical disability (EDSS), fatigue (FSS), the somatic and nonsomatic components of depression (BDI), disease progression rate [Multiple Sclerosis Severity Score (MSSS)], and psychotropic medication. Cognitive impairment had a prevalence of 30.5% in patients affecting preferentially attention, executive functions, processing speed and visual perception/organization. MSSS was not associated with cognitive impairment, depression, or fatigue. In regression models, cognitive performance was best predicted by the nonsomatic symptoms of depression alone or in combination with physical disability. Exclusion of patients with any psychotropic medication did not influence the results. Our results underscore the importance of evaluating depressive symptoms when suspecting cognitive impairment in patients with RRMS.

Executive functions predict the success of top-soccer players.

While the importance of physical abilities and motor coordination is non-contested in sport, more focus has recently been turned toward cognitive processes important for different sports. However, this line of studies has often investigated sport-specific cognitive traits, while few studies have focused on general cognitive traits. We explored if measures of general executive functions can predict the success of a soccer player. The present study used standardized neuropsychological assessment tools assessing players' general executive functions including on-line multi-processing such as creativity, response inhibition, and cognitive flexibility. In a first cross-sectional part of the study we compared the results between High Division players (HD), Lower Division players (LD) and a standardized norm group. The result shows that both HD and LD players had significantly better measures of executive functions in comparison to the norm group for both men and women. Moreover, the HD players outperformed the LD players in these tests. In the second prospective part of the study, a partial correlation test showed a significant correlation between the result from the executive test and the numbers of goals and assists the players had scored two seasons later. The results from this study strongly suggest that results in cognitive function tests predict the success of ball sport players.

Social problem solving, autobiographical memory, trauma, and depression in women with borderline personality disorder and a history of suicide attempts.

OBJECTIVES: The primary aim of this study was to compare the retrieval of autobiographical memory and the social problem-solving performance of individuals with borderline personality disorder (BPD) and a history of suicide attempts, with and without concurrent diagnoses of depression and/or post-traumatic stress disorder (PTSD), to that of controls. Additionally, the relationships between autobiographical memory, social problem-solving skills, and various clinical characteristics were examined in the BPD group. DESIGN: Individuals with BPD who had made at least two suicide attempts were compared to controls with regard to specificity of autobiographical memory and social problem-solving skills. Autobiographical memory specificity and social problem-solving skills were further studied in the BPD group by comparing depressed participants to non-depressed participants; and autobiographical memory specificity was also studied by comparing participants with and without PTSD. METHOD: A total of 47 women with a diagnosis of BPD and 30 controls completed the Autobiographical Memory Test, assessing memory specificity, and the means-end problem solving-procedure, measuring social problem-solving skills. The prevalence of suicidal/self-injurious behaviour, and the exposure to violence, was also assessed in the BPD group. RESULTS: Compared to controls, participants with BPD showed reduced specificity of autobiographical memory, irrespective of either concurrent depression, previous depression, or concurrent PTSD. The depressed BPD group displayed poor problem-solving skills. Further, an association between unspecific memory and poor problem-solving was displayed in the BPD group. CONCLUSION: Our results confirmed that reduced specificity of autobiographical memory is an important characteristic of BPD individuals with a history of suicide attempt, independent of depression, or PTSD. Reduced specificity of autobiographical memory was further related to poor social problem-solving capacity in the BPD group.

Emotionally controlled decision-making and a gene variant related to serotonin synthesis in women with borderline personality disorder.

The Iowa Gambling Task (IGT) was used to examine (i) social decision-making in women with borderline personality disorder (BPD), and (ii) the relationship between impaired decision-making and the tryptophan hydroxylase-1 (TPH-1) gene, involved in serotonin synthesis. Forty-two women with BPD and a history of suicide attempts were genotyped, and the frequency of a TPH-1 haplotype previously uniquely associated with BPD was calculated. The BPD group scored significantly lower than a control group in the IGT. Furthermore, the TPH-1 haplotype displayed a significantly higher frequency in BPD participants with impaired decision making, compared to BPD participants with normal scores. These findings suggest that impaired decision-making as determined by the IGT is a feature of BPD and may be (i) associated with serotonin dysfunction, and (ii) possibly relevant for suicidal behavior.

Cognitive impairment correlates to low auditory event-related potential amplitudes in type 1 diabetes.

Type 1 diabetes may be associated with a mild decline in cognitive function and mostly in mental speed. In order to study the pathophysiology of this, we have investigated auditory event-related potentials (AERP) and their relation to cognitive function in diabetes patients. AERP was recorded in patients with type 1 diabetes (n=119) and in a healthy control group (n=61). AERP was obtained with an odd-ball and a two-stimulus paradigm. Cognitive function was evaluated in 10 domains in the patients. Patients had normal N100 latency, but a highly significant decrease in auditory N100 amplitude (p<10(-6)), which correlated with a decrease in psychomotor speed but not with function in other domains. Psychomotor speed also correlated with P300 amplitude, although P300 amplitude was only slightly decreased in the patients. Even stronger correlations were found with the parietal N100-P300 peak-to-peak amplitude, which correlated both to psychomotor speed (rho=0.61, p<10(-7)) and processing speed (p<0.005). P300 latency was increased in patients, and this correlated to low global cognitive score and older age. We conclude that the decline in psychomotor speed in type 1 diabetes is associated with a highly significant decrease in the auditory N100 peak amplitude. This association and the relatively small abnormality in P300 latency is quite different from those generally found in dementia, and suggest that the underlying defect is located in the brain stem or the white matter. Presumably small conduction defects in ascending fibers can distort the firing synchrony necessary for signal generation in the cortex.

Predictors of cognitive impairment in type 1 diabetes.

A decline in cognitive function has been reported in type 1 diabetes, but its relation to different disease factors such as hypoglycemic events and peripheral neuropathy is controversial. The objective of the present study was to identify factors that are important for cognitive impairment in type 1 diabetes. A cross-sectional study was performed in adult patients (N=150) with type 1 diabetes (duration 26.6+/-11.4 years). Function in different cognitive domains was evaluated by the same trained examiner, in order to eliminate inter-rater variability. Peripheral nerve function was tested quantitatively. Predictors of cognitive impairment were identified using multiple regression analysis. The major finding was that long diabetes duration and young age of diabetes onset were the strongest predictors of low scores in psychomotor speed, memory, processing speed, attention, working memory, verbal ability, general intelligence, executive functions and a low global score. The number of previous hypoglycemic events had no defined effect upon cognitive functioning. Other significant predictors were low compound muscle action potential (CMAP) (for visual perception-organization), old age (for visual-spatial ability), short stature, high BMI and hypertension. Presence of retinopathy and long-term metabolic control correlated with nerve conduction defects, but not with cognitive impairment. Although a history of hypoglycemic events was not a predictor of cognitive impairment, we cannot exclude the possibility that the influence of young age of diabetes onset depends on the effect of hypoglycemic events early in life. The clinical relationships of cognitive impairment differ from those of peripheral neuropathy, indicating a different pathogenesis. The influence of diabetes duration, BMI, height, age and CMAP may suggest that loss of the neuroprotective effects of insulin or insulin-like growth factors plays a role.
