The effect of repeated concussions on clinical and neurocognitive symptom severity in different contact sports.

INTRODUCTION: The potential consequences of repeated concussions in sport are well documented. However, it remains unclear whether the cumulative impact of sports-related concussions differs between different contact sports. Therefore, the aim of the current study was to investigate the cumulative effects of sports-related concussions on clinical and neurocognitive health in different contact sports. MATERIALS AND METHODS: In a prospective multicenter study, we examined 507 (74 females) active professional athletes between 18 and 40 years of age from five different contact sports (soccer, handball, American football, basketball, and ice hockey). Data collection involved concussion history, clinical symptom evaluation, neurocognitive assessment, and the collection of other sports-related information. Composite scores were built for clinical symptoms (such as neck pain and balance disturbances) and for neurocognitive symptoms (such as memory and attention impairments). RESULTS: Athletes having suffered 3+ concussions in the past showed disproportionally higher clinical symptom severity than athletes with less than three concussions across all sports. The level of clinical symptom burden in athletes with 3+ concussions indicated mild impairment. The number of past concussions did not affect neurocognitive performance. DISCUSSION: Repeated sports-related concussions appear to have a cumulative impact on clinical-but not cognitive-symptom severity. Although clinical symptom burden in athletes with 3+ concussions in the past was not alarmingly high yet in our sample, increased caution should be advised at this point. Despite few exceptions, results are similar for different contact sports, suggesting a similar multidisciplinary concussion management across all types of sport.

The magnitude of neurocognitive impairment is overestimated in depression: the role of motivation, debilitating momentary influences, and the overreliance on mean differences.

BACKGROUND: Meta-analyses agree that depression is characterized by neurocognitive dysfunctions relative to nonclinical controls. These deficits allegedly stem from impairments in functionally corresponding brain areas. Increasingly, studies suggest that some performance deficits are in part caused by negative task-taking attitudes such as poor motivation or the presence of distracting symptoms. A pilot study confirmed that these factors mediate neurocognitive deficits in depression. The validity of these results is however questionable given they were based solely on self-report measures. The present study addresses this caveat by having examiners assess influences during a neurocognitive examination, which were concurrently tested for their predictive value on performance. METHODS: Thirty-three patients with depression and 36 healthy controls were assessed on a battery of neurocognitive tests. The examiner completed the Impact on Performance Scale, a questionnaire evaluating mediating influences that may impact performance. RESULTS: On average, patients performed worse than controls at a large effect size. When the total score of the Impact on Performance Scale was accounted for by mediation analysis and analyses of covariance, group differences were reduced to a medium effect size. A total of 30% of patients showed impairments of at least one standard deviation below the mean. CONCLUSIONS: This study confirms that neurocognitive impairment in depression is likely overestimated; future studies should consider fair test-taking conditions. We advise researchers to report percentages of patients showing performance deficits rather than relying solely on overall group differences. This prevents fostering the impression that the majority of patients exert deficits, when in fact deficits are only true for a subgroup.

Therapeutic alliance and dropout in patients with borderline pathology receiving residential dialectical behavior therapy.

BACKGROUND: This study focused on the impact of therapeutic alliance on therapy dropout in a naturalistic sample of patients with borderline pathology receiving dialectical behavior therapy (DBT) in a residential setting. We assumed that low therapeutic alliance shortly after admission would be associated with elevated dropout. METHODS: 44 participants with borderline pathology (≥ 3 DSM-5 borderline personality disorder criteria) in a residential DBT program completed a quality assurance questionnaire set assessing demographic information, pretreatment psychopathology and therapeutic alliance during the first seven days of their residential stay. Predictors of dropout were investigated using binary logistic regression analyses. RESULTS: The dropout rate was 34.1% (n = 15). In binary logistic regression analyses with variables covering demographic and clinical characteristics, comorbidities and childhood trauma history, only the therapeutic alliance significantly predicted dropout (z = -2.371, p = .018). CONCLUSIONS: This study supports the importance of therapy process variables, here the therapeutic alliance at the beginning of treatment, as predictors of therapy dropout in borderline pathology. If this finding is replicated, it shows the potential importance of monitoring the therapeutic relationship throughout the therapeutic process.

Impaired Color Discrimination in Alzheimer Disease Dementia.

OBJECTIVE: Patients with Alzheimer disease dementia (ADD) often show impaired orientation and navigation. Signage offers an opportunity to compensate for these deficits, communicate information efficiently and facilitate wayfinding. Certain properties of signs such as colors and contrasts may beneficially affect the uptake and processing of information particularly in ADD patients. METHODS: Thirty-six healthy older adults and 30 ADD patients performed a computerized color perception task that required discriminating different color combinations. The effects of different contrast features on performance accuracy and speed in the 2 experimental groups were examined by nonparametric mixed analysis of variances. RESULTS: Analyses revealed a significant effect of contrast polarity on reaction times, significant effects of group on reaction times and errors as well as a marginally significant interaction of group×color on errors. All participants benefitted from positive contrast polarity (ie, dark target on lighter background) as indicated by increased performance speed. Furthermore, ADD patients reacted slower and less accurate than healthy controls, but showed higher accuracy at black-white and red-yellow than at blue-green color combinations. CONCLUSIONS: Our findings suggest the implementation of signs with positive contrast polarity to ensure faster reactions. In addition, certain color combinations may enhance accuracy, particularly in patients with ADD.

Effectiveness of supported housing versus residential care in severe mental illness: a multicenter, quasi-experimental study.

PURPOSE: Up to now there are only few studies and no RCT comparing efficacy or effectiveness of supported housing (SH) versus residential care (RC) in severe mental illness (SMI) without homelessness. Here we present an observational follow-up study in SMI subjects, who entered SH or RC, to compare clinical and functional outcomes 2 years later. METHODS: In this prospective study in more than 30 locations throughout a German federal state, we included SMI subjects, who entered SH (n = 153) or RC (n = 104). About one quarter suffered from each substance use, psychotic, affective, or other disorders. To avoid sampling bias, we used the propensity score matching method to establish a quasi-experimental design. Outcome measures were social functioning (SFS), the number of psychiatric hospitalisations, psychopathology (SCL-9-K), and quality of life (MANSA). Apart from descriptive methods we analysed primarily using repeated-measures ANOVAS. RESULTS: Our analyses revealed significant effects of time for all outcomes in both study groups. However, there were not any group differences of outcome measures, i.e., not any significant effects of group or interactional effects of group x time. Moreover, these results hold true for intent-to-treat and per-protocol sample analyses. CONCLUSION: The results show, that SH and RC for non-homeless people with SMI achieve the same clinical and psychosocial outcomes across a 2-year period. Taking into account the users' preferences, the present findings should give reason to ensure the availability of affordable housing and to support the expansion of supported housing approaches.

[Collaborative Assessment and Management of Suicidality: An Effective Brief Intervention for the Treatment of Suicidal Patients]. / Das "Collaborative Assessment and Management of Suicidality" (CAMS) ­ Eine wirksame (Kurz-) Intervention zur Behandlung von suizidalen Patienten.

Das "Collaborative Assessment and Management of Suicidality" (CAMS) ist einer von mehreren Interventionsansätzen zur Behandlung von suizidalen Patienten und Patientinnen und wurde weltweit seit 3 Jahrzehnten untersucht und weiterentwickelt. Das CAMS ist auf die Etablierung einer tragenden therapeutischen Beziehung auf Augenhöhe zu einer suizidalen Person ausgerichtet. Der Patient wird aktiv an der Einschätzung seines Suizidrisikos beteiligt und zum "Mitverfasser" seines eigenen suizidspezifischen Behandlungsplans. Das konkrete therapeutische Vorgehen wird durch ein vielseitig anwendbares Instrument, die sogenannte Suizidstatusform (SSF), strukturiert und geleitet. Das CAMS kann von verschiedenen therapeutischen Berufsgruppen sowie bei Patienten und Patientinnen mit unterschiedlichen Diagnosen angewandt werden. Die Wirksamkeit im Hinblick auf eine Verringerung von Suizidgedanken, der allgemeinen psychischen Belastung und Depressivität sowie auf eine Zunahme von Hoffnung und Zuversicht ist mittlerweile empirisch gut belegt.The "Collaborative Assessment and Management of Suicidality" (CAMS) is an intervention approach for the treatment of suicidal patients that has been studied and developed for three decades around the world. CAMS is focused on establishing a continuing therapeutic relationship at eye level with a suicidal person. The patient is actively involved in assessing his or her suicide risk and becomes the "co-author" of his or her own suicide-specific treatment plan. The specific therapeutic procedure is structured and guided by a versatile instrument called the Suicide Status Form (SSF). CAMS can be applied by different therapeutic professional groups to patients with different diagnoses. Its effectiveness in reducing suicidal ideation, general psychological distress and depressiveness, and increasing hope and confidence is now empirically well established.

Borderline personality disorder and childhood trauma: Exploring the buffering role of self-compassion and self-esteem.

OBJECTIVES: The aim of the present study was to investigate whether patients with borderline personality disorder (BPD) show lower self-compassion and self-esteem than healthy controls and whether patients' self-compassion and self-esteem moderate the association between childhood trauma and the severity of their BPD symptoms. METHOD: Self-reported self-compassion, self-esteem, and the current severity of BPD symptoms were assessed in 35 female patients with BPD and 35 age-matched control participants. Further, traumatic childhood experiences were recorded in the patient group. RESULTS: Patients with BPD reported significantly lower self-compassion and self-esteem compared to healthy controls. In addition, self-compassion but not self-esteem moderated the positive correlation between childhood trauma and the severity of BPD symptoms. DISCUSSION: Self-compassion appears to buffer the negative consequences of childhood traumatization. Therefore, cultivating self-compassion may be an important therapeutic aim for patients with BPD.

Symbol Comprehension in Patients With Alzheimer Disease Dementia, Mild Cognitive Impairment, and Major Depressive Disorder.

INTRODUCTION: Previous research suggests that specific symbol features attenuate symbol comprehension deficits in seniors suffering from Alzheimer disease dementia (ADD). However, it remains unclear whether these findings also apply to other disorders associated with cognitive dysfunctions. METHODS: Ninety healthy controls, 30 patients with major depressive disorder (MDD), 35 patients with mild cognitive impairment (MCI), and 55 patients with ADD performed a Symbol Processing Task with 4 different symbol categories. Nonparametric between×within subjects analyses were conducted to examine the impact of different symbol categories on performance accuracy in all experimental groups. RESULTS: Analyses revealed a higher symbol comprehension accuracy in healthy seniors than in MDD, MCI, and ADD patients, with the lowest accuracy rates shown by ADD patients. Although the type of symbol hardly affected performance accuracy in healthy seniors and MDD patients, different symbol categories influenced the performance of MCI and ADD patients significantly. CONCLUSIONS: Our findings indicate that symbols with distracting features impede symbol comprehension in ADD and MCI. Symbols with visual cues, by contrast, facilitate symbol comprehension in ADD and may even be advantageous over standardized symbols used in public life.

Collaborative Assessment and Management of Suicidality (CAMS) compared to enhanced treatment as usual (E-TAU) for suicidal patients in an inpatient setting: study protocol for a randomized controlled trial.

BACKGROUND: The Collaborative Assessment and Management of Suicidality (CAMS) is a therapeutic framework that has been shown to reduce suicidal ideation and overall symptom distress. CAMS has not been previously evaluated in a standard acute inpatient mental health care setting with only short treatment times for suicidal patients. In this randomized controlled trial (RCT) we are investigating whether CAMS is more effective than Enhanced-Treatment as Usual (E-TAU) in reducing suicidal thoughts as primary outcome variable. We are also investigating depressive symptoms, general symptom relief, and the quality of the therapeutic alliance as secondary outcomes. METHODS/DESIGN: This RCT is designed as a single-center, two-armed, parallel group observer-blinded clinical effectiveness investigation. We are recruiting and randomizing 60 participants with different diagnoses, who are admitted as inpatients because of acute suicidal thoughts or behaviors into the Clinic for Psychiatry and Psychotherapy, Ev. Hospital Bethel in Bielefeld, Germany. The duration of treatment will vary depending on patients' needs and clinical assessments ranging between 10 and 40 days. Patients are assessed four times, at admission, discharge, 1 month, and 5 months post-discharge. The primary outcome measure is the Beck Scale for Suicide Ideation. Other outcome measures are administered as assessment timepoints including severity of psychiatric symptoms, depression, reasons for living, and therapeutic relationship. DISCUSSION: This effectiveness study is being conducted on an acute ward in a psychiatric clinic where patients have multiple problems and diagnoses. Treatment is somewhat limited, and therapists have a large caseloads. The results of this study can thus be generalizable to a typical inpatient psychiatric hospital settings. TRIAL REGISTRATION: This clinical trial has been retrospectively registered with the German Clinical Trials Register; registration code/ DRKS-ID: DRKS00013727 (on January 12, 2018). In addition, the study was also registered with the International Clinical Trials Registry Platform of the World Health Organization (identical registration code). Registry Name: "Evaluation von CAMS versus TAU bei suizidalen Patienten - Ein stationärer RCT".

Nonacceptance of negative emotions in women with borderline personality disorder: association with neuroactivity of the dorsal striatum

Background: Emotion dysfunction is a key symptom in patients with borderline personality disorder (BPD) and is considered a consequence of dysfunctional emotion regulation (e.g., reduced emotion acceptance). In the present functional MRI (fMRI) study, we investigated the neural correlates of habitual emotion acceptance in individuals with BPD. Methods: Female patients with BPD and female healthy controls passively viewed negative and neutral movie clips of faces during fMRI. We assessed emotion acceptance using the Emotion Acceptance Questionnaire (EAQ). To examine brain activation associated with habitual emotional acceptance of negative stimuli, the EAQ score was included as a regressor of interest in brain data analyses of activation intensity during negative compared with neutral movies. Results: We included 20 women with BPD and 20 heatlhy controls in our analysis. Compared with healthy controls, patients with BPD showed significantly more activation in frontostriatal brain regions (i.e., left superior frontal gyrus, right caudate) as well as in the left precuneus, left precentral gyrus, left posterior cingulate cortex and left hippocampus when confronted with negative (v. neutral) stimuli. Patients with BPD reported decreased emotion acceptance compared with healthy controls, and habitual emotion acceptance was inversely associated with activation of striatal areas (i.e., left putamen, left caudate) in patients with BPD. Limitations: Causal conclusions are not possible. Comorbid diagnoses were not excluded, and only female participants were investigated. Stimuli were not rated immediately and may not be generalizable to all negative emotions. We cannot make any statements about other emotion-regulation strategies that may have been applied here. Conclusion: Data indicate that striatal hyperactivation during the processing of negative stimuli in women with BPD is related to their decreased disposition to accept unpleasant emotional states. Thus, individuals with BPD may benefit from therapy approaches that focus on emotion acceptance in order to normalize emotional reactions.

Effectiveness and feasibility of Narrative Exposure Therapy (NET) in patients with borderline personality disorder and posttraumatic stress disorder - a pilot study.

BACKGROUND: This pilot study focused on the feasibility and potential effectiveness of a protocol based on Narrative Exposure Therapy (NET) that was integrated into a standard inpatient program to treat patients with comorbid Borderline Personality Disorder (BPD) and Posttraumatic Stress Disorder (PTSD). METHODS: Eleven patients (1 male, 10 female) without previous stabilization periods or the absence of intentional self-injury received NET during a ten-week inpatient program. Patients were assessed again at post-treatment and a 12-month follow-up. RESULTS: Drop-out rates during treatment were low, with 90.9 % completing NET. Furthermore, acceptance of NET was high, with only one patient rejecting treatment. The program was safe because it did not lead to aggravations in symptom severity at either the post-treatment or 12-month follow-up. Additionally, the rate of self-harming behaviors throughout the treatment phase was low (18.2 %). In fact, treatment was associated with positive effects on PTSD and BPD symptom severity as well as secondary outcome measures, including depression, dissociation and quality of life. CONCLUSIONS: The present study found that NET is feasible and safe in an inpatient setting for treating highly burdened patients with BPD and PTSD. There is also evidence for the potential effectiveness of NET in this highly burdened population. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT02517723 . Registered 6 January 2014.

Deficient symbol processing in Alzheimer disease.

Symbols and signs have been suggested to improve the orientation of patients suffering from Alzheimer disease (AD). However, there are hardly any studies that confirm whether AD patients benefit from signs or symbols and which symbol characteristics might improve or impede their symbol comprehension. To address these issues, 30 AD patients and 30 matched healthy controls performed a symbol processing task (SPT) with 4 different item categories. A repeated-measures analysis of variance was run to identify impact of different item categories on performance accuracy in both the experimental groups. Moreover, SPT scores were correlated with neuropsychological test scores in a broad range of other cognitive domains. Finally, diagnostic accuracy of the SPT was calculated by a receiver-operating characteristic curve analysis. Results revealed a global symbol processing dysfunction in AD that was associated with semantic memory and executive deficits. Moreover, AD patients showed a disproportional performance decline at SPT items with visual distraction. Finally, the SPT total score showed high sensitivity and specificity in differentiating between AD patients and healthy controls. The present findings suggest that specific symbol features impede symbol processing in AD and argue for a diagnostic benefit of the SPT in neuropsychological assessment.

Subjective memory complaints and memory performance in patients with borderline personality disorder.

BACKGROUND: It is still a matter of debate as to whether patients with Borderline Personality Disorder (BPD) suffer from memory deficits. Existing studies indicate no or small impairments in memory test performance. However, it was shown in patients with related disorders, such as depression, that self-reported impairment exceeds test malfunction. In the present study we assessed memory performance of BPD patients through the use of memory tests and a questionnaire for subjective memory complaints (SMC) in everyday life. METHODS: Thirty-two patients with BPD and 32 healthy control subjects were included in the study. The groups of subjects were comparable with respect to age, education, and gender. Subjects completed verbal and nonverbal memory tests, as well as the everyday memory questionnaire (EMQ). RESULTS: BPD patients reported severe SMC but did not show memory test impairment. The results remained stable even when all BPD patients with acute or lifetime depression comorbidity were excluded from analyses. In both groups, SMC and test performances were not related but in BPD patients SMC were related to BPD symptoms. CONCLUSIONS: Our data indicate memory impairment of BPD patients in everyday life. However, it cannot be ruled out that increased memory complaints result from patients' negative self-perception. Future research needs to clarify the reasons for memory complaints of BPD patients.

The impact of self-reported childhood trauma on emotion regulation in borderline personality disorder and major depression.

Early life stress is said to play a critical role in the development of borderline personality disorder (BPD) and major depressive disorder (MDD), but the underlying mediating factors remain uncertain. This study aimed to investigate self-reported childhood trauma, emotion regulation difficulties, and their associations in a sample of BPD (n = 49) and MDD (n = 48) patients and healthy control participants (n = 63). Multiple regressions were used to evaluate the impact of the quality and severity of self-reported childhood trauma on self-reported emotion regulation. The results supported an association between self-reported maltreatment experiences, especially emotional abuse and neglect, and emotion regulation difficulties. Additional analyses showed that emotion regulation difficulties influence the association between self-reported emotional abuse and acute symptomatology in the BPD subgroup. Emotion regulation difficulties may be 1 pathway through which early life stress, particularly emotional abuse, increases the risk for developing BPD symptomatology.

Somatic Factors Predict On-Road Driving Skills in Older Drivers and Drivers with Mild Cognitive Impairment.

BACKGROUND: On-road driving skills can be impaired in older drivers and drivers with mild cognitive impairment (MCI) due to different driving-relevant deficits. Among these deficits, somatic factors have received little attention so far. METHODS: In a prospective observational on-road driving study, we examined whether somatic factors can predict on-road driving skills in a mixed sample of healthy older drivers and drivers with MCI (n = 99) and whether the inclusion of age explains additional variance. Somatic factors included the number of prescribed drugs, visual acuity, peripheral visual field integrity, mobility of the cervical spine, and hearing impairment. A hierarchical regression analysis was used to predict on-road driving skills by adding the somatic factors in the first step and age in the second step. RESULTS: Results revealed that the combination of somatic factors significantly predicted on-road driving skills (R2adjusted = 0.439). The inclusion of age led to a significant increase of explained variance (R2adjusted = 0.466). CONCLUSIONS: Our results suggest that somatic factors can accurately predict on-road driving skills in healthy older drivers and drivers with MCI. In addition, our results suggest that there is a significant but rather small effect of age beyond somatic changes.

Two Sides of the Same Coin in Female Borderline Personality Disorder: Self-Reported Guilt and Shame and Their Neurofunctional Correlates.

OBJECTIVE: Patients with borderline personality disorder (BPD) report to be especially prone to social emotions like shame and guilt. At the same time, these emotions seem to play an important role in BPD pathology. The present study aimed to deepen the knowledge about the processes behind shame and guilt in patients with BPD. METHODS: Twenty patients with BPD and twenty healthy controls (HCs) took part in an experiment that induced shame and guilt by imagining scenarios during scanning using functional brain imaging. Participants also filled out self-report questionnaires and took part in diagnostic interviews. RESULTS: BPD patients reported more proneness to guilt but not to shame than the HCs. There was no difference in the self-reported intensity rating of experimentally induced emotions between the groups. Between-group contrast of neural signals in the shame condition revealed a stronger activation of cingulate and fusiform gyrus for the BPD patients compared to the controls, and a more pronounced activation in the lingual gyrus and cuneus for the HCs. In the guilt condition, activation in the caudate nucleus, the fusiform gyrus, and the posterior cingulate cortex was stronger in BPD patients, while HC showed stronger activations in cuneus, lingual gyrus, and fronto-temporal regions. CONCLUSIONS: Differences in the neuro-functional processes between BPD patients and HC were found, even though the two groups did not differ in their self-report of subjective proneness to guilt and emotional intensity of shame and guilt during the experiment. While the HCs may be engaged more by the emotional scenarios themselves, the BPD patients may be more occupied with cognitive regulatory and self-referential processing.

Two Sides of Theory of Mind: Mental State Attribution to Moving Shapes in Paranoid Schizophrenia Is Independent of the Severity of Positive Symptoms.

BACKGROUND: Theory of Mind (ToM) impairment has repeatedly been found in paranoid schizophrenia. The current study aims at investigating whether this is related to a deficit in ToM (undermentalizing) or an increased ToM ability to hyperattribute others' mental states (overmentalizing). METHODS: Mental state attribution was examined in 24 patients diagnosed with schizophrenia (12 acute paranoid (APS) and 12 post-acute paranoid (PPS)) with regard to positive symptoms as well as matched healthy persons using a moving shapes paradigm. We used 3-T-functional magnetic resonance imaging (fMRI) to provide insights into the neural underpinnings of ToM due to attributional processes in different states of paranoid schizophrenia. RESULTS: In the condition that makes demands on theory of mind skills (ToM condition), in patients with diagnosed schizophrenia less appropriate mental state descriptions have been used, and they attributed mental states less often to the moving shapes than healthy persons. On a neural level, patients suffering from schizophrenia exhibited within the ToM network hypoactivity in the medial prefrontal cortex (MPFC) and hyperactivity in the temporo-parietal junction (TPJ) as compared to the healthy sample. CONCLUSIONS: Our results indicate both undermentalizing and hypoactivity in the MPFC and increased overattribution related to hyperactivity in the TPJ in paranoid schizophrenia, providing new implications for understanding ToM in paranoid schizophrenia.

Everyday memory in patients with depression: An explorative pilot study using an ecological assessment paradigm.

BACKGROUND: People with major depressive disorder (MDD) often experience significant memory problems in their daily lives, which, however, frequently do not correspond to standardized memory test (SMT) results. The present pilot study aimed to examine the everyday memory performance of people with MDD by means of an ecological assessment paradigm (EAP). METHODS: Participants were unexpectedly called one week after their neuropsychological test assessment and asked about their memories of specific details of the former test situation. Associations of this EAP with SMT, subjective everyday memory problems, and symptom coping were exploratively analyzed. RESULTS: The study involved 22 MDD inpatients (M = 42.5 years, 64% female) and 22 comparable healthy control persons. MDD patients showed a significantly reduced performance in the EAP as well as in the SMT and they reported more memory problems in their daily lives. However, the EAP was not related to SMT results assessed a week before. Moreover, only the EAP was significantly associated with subjective daily memory problems and (distraction) coping style in the MDD group. CONCLUSIONS: The EAP appears to better reflect the everyday memory problems of persons with depression than standardized test procedures. However, the findings need to be validated by further research with larger samples.

Combined physical activity training versus aerobic activity training in unipolar depressive disorder: a quasi-randomised evaluation study.

OBJECTIVE: The positive effect of sport and exercise interventions on the treatment of unipolar depressive disorder (UDD) is well documented with respect to aerobic exercise. However, few studies have determined the effectiveness of other types of interventions (e.g., weight training, body and mind oriented, qigong or progressive muscle relaxation). Additionally, the effectiveness of specific combined sport and exercise approaches has rarely been investigated. Therefore, recommendations for the use of sport and exercise therapy to treat UDD have been developed. METHODS: This quasi-randomised study used a pretest/posttest design to compare the effectiveness of two different interventions (aerobic activity training vs. combined physical activity training) on psychiatric outcome parameters in a day clinic psychiatric setting. A total of 62 participants were quasi-randomised to one of the two conditions. Affective, cognitive, psychosocial and neuropsychological changes were assessed by a battery of questionnaires before (t1) and after (t2) treatment. Accelerometers were used to assess energy consumption. RESULTS: The results show that both training interventions have similar effects on the treatment of UDD. CONCLUSION: These findings highlight the effectiveness of different physical activities in the treatment of UDD and provide further information for good clinical practice.

Give Me a Sign: Concrete Symbols Facilitate Orientation in Alzheimer's Disease Dementia.

OBJECTIVES: Persons with Alzheimer's disease dementia (ADD) often show impaired orientation, particularly in unknown environments. Signs may offer an opportunity to compensate for these deficits and thus improve participation. METHODS: We assessed 30 persons with ADD and 36 healthy controls by using a sign comprehension paradigm (SCP) in a real-life environment. Nonparametric mixed model analyses of variance were used to analyze the effect of different symbols and additional scripture (coding condition) on SCP performance speed and accuracy. RESULTS: Analyses revealed a significant main effect of symbol design on SCP speed as well as an interaction effect of group × symbol, indicating a benefit of concrete, optimized signs for persons with ADD. Furthermore, analyses of SCP error rates revealed the main effects of group and coding condition as well as an interaction effect of group × coding. Persons with ADD made more errors than healthy controls, but SCP error rates decreased significantly in ADD in the double-coding condition. DISCUSSION: Our findings revealed an advantage of concrete double-coded symbols over conventional symbols and therefore strongly suggest the implementation of concrete double-coded signs to support older people living with ADD.
