Impaired awareness of movement disorders in Parkinson’s disease

Background

This study analyzed the presence of awareness of movement disorders (dyskinesias and hypokinesias) in 25 patients with Parkinson’s disease (PD) and motor fluctuations (dyskinesias, wearing off, on–off fluctuations). Of the few studies that have dealt with this topic, none have analyzed the differences in the awareness of motor deficits by comparing the on and off states using motor scales and an extensive battery of tests to assess cognitive and behavioral functioning.

Methods

PD patients were compared on three different scales that we have devised to measure awareness of movement disorders: Global Awareness of Movement (GAM) Disorders, dyskinesia/hypo-bradykinesia rating scales.

Results

Data showed that PD patients had greater awareness and psychological suffering in the off state than in the on state. In particular, they were troubled by motor disabilities related to hypokinesias and had mood-related symptoms and a perception of disability in activities of daily living. Interestingly, patients only showed a selective reduction of awareness of movement disorders associated with executive functions and related to dyskinesias in the on state, compared to a preserved awareness of hypokinesias in the off state. On the contrary, no association with executive functions was found in the off state.

Conclusion

Our findings suggest that the dopaminergic overstimulation of mesocorticolimbic pathways may cause a dysfunction of prefrontal–subcortical connections related to the impaired insight.     

Expressed emotion and Milan systemic intervention: a pilot study on families of people with a diagnosis of schizophrenia

This article presents the results of a pilot study carried out on families of people with a diagnosis of schizophrenia (high‐frequency users of psychiatric services) using a standardized version of systemic family intervention based on the Milan Approach (‘Circular Interview’). We used expressed emotion (EE) to compare and assess two homogeneous samples of families, a treatment group (n = 10) and a control group (n = 8). We found that families participating in circular interviews showed a reduction in criticism, while 30% of their members with a diagnosis of schizophrenia relapsed. Families not receiving treatment showed no changes in EE levels, while 62.5% of their members with a diagnosis of schizophrenia relapsed. Although the difference in relapse rates is not statistically significant, these results justify further studies on the use of nondirective systemic intervention with families of people with a diagnosis of schizophrenia.     

Group Cancellation and Resolution

We establish a connection between the geometric methods developed in the combinatorial theory of small cancellation and the propositional resolution calculus. We define a precise correspondence between resolution proofs in logic and diagrams in small cancellation theory, and as a consequence, we derive that a resolution proof is a 2-dimensional process. The isoperimetric function defined on diagrams corresponds to the length of resolution proofs.     

Being seen or being watched? A psychoanalytic perspective on body dysmorphia

The focus of this paper is on individuals who present as excessively preoccupied with their body, perceiving some aspect(s) to be 'ugly' such that they feel compelled to alter and/or conceal this 'ugly' body part. These difficulties are understood as symptoms of an underlying narcissistic disturbance. The author suggests that the relative pervasiveness of an identification with a 'super'-ego accounts for the degree of severity of the disturbance (increasing the compulsion to alter and/or conceal the hated body part) and that it has implications for the patient's accessibility in analytic treatment. Understanding the vicissitudes of the development of the body–self in the context of the earliest relationship with the 'object of desire' is core to helping these patients because of the quality of the identifications that ensue and that are then enacted the transference.     

The aggression test as a possible taxonomic tool in the Formica rufa group

The intra- and interspecific aggressive behavior of Formica polyctena, a species of the Formica rufa group, was analyzed and quantified both in the laboratory and in the field. This behavior was used as a potential taxonomic tool for gaining a better understanding of the phyletic relationships among the species within the group. No overt aggression was recorded toward members of the same species. To examine interspecific relationships, F. polyctena was first confronted with F. cunicularia, to ascertain its aggressiveness toward a distantly related species. All such encounters led immediately to overt and prolonged attacks with virtually no initial mutual inspection. This suggests that recognition of strangeness of the unrelated species is almost immediate in F. polyctena, as previously observed in F. lugubris and F. rufa toward the same antagonist. Subsequently, F. polyctena was contrasted with F. lugubris and F. rufa (also belonging to the F. rufa group) in order to compare these related species. Fierce attacks accompanied by all the elements of conflict behavior were observed in all encounters. Moreover, the degree of aggression in the field was higher than in laboratory-paired ants, possibly because of a territorial effect. These data and our previous and similar research indicate that the relationships between F. lugubris and F. rufa are closer than between these two species and F. polyctena. In considering different viewpoints on this problem, the validity of the aggression test is discussed and the opportunity to compare levels of aggressiveness among strictly sympatric samples of red wood ant species gathered from the same ecological environment are considered.     

Intellectual Humility as Attitude

Intellectual humility, I argue in this paper, is a cluster of strong attitudes (as these are understood in social psychology) directed toward one's cognitive make‐up and its components, together with the cognitive and affective states that constitute their contents or bases, which serve knowledge and value‐expressive functions. In order to defend this new account of humility I first examine two simpler traits: intellectual self‐acceptance of epistemic limitations and intellectual modesty about epistemic successes. The position defended here addresses the shortcomings of both ignorance and accuracy based accounts of humility.     

IMPACT OF PARENTAL BINGE EATING DISORDER: EXPLORING CHILDREN'S EMOTIONAL/BEHAVIORAL PROBLEMS AND THE QUALITY OF PARENT–CHILD FEEDING INTERACTIONS

This study examines psychopathological problems in children of parents with binge eating disorder (BED), particularly the effect of parental diagnosis on their offspring's psychopathology and the mediating power of the quality of parent–infant feeding interactions. Two hundred parents and their offspring were administered a questionnaire for the assessment of their children's psychopathology at 18 (T1) and 36 (T2) months of age. An observational measure to evaluate feeding interactions was administered at T1. Children with both parents with BED showed the highest affective, anxiety, oppositional/defiant, and autism spectrum problems, but no influence of paternal diagnosis was found on the offspring's psychopathology. Maternal BED had an influence on children's affective and autism spectrum problems, and diagnosis of BED in both parents had an effect on infants’ affective problems. Paternal BED had an effect on oppositional/defiant problems through the quality of father–infant interactions, and maternal BED had an effect on the offspring's affective and anxiety problems through the mediation of mother–infant interactions. These results suggest the importance of intervention programs focusing both on parental psychopathology and on mother–child and father–child feeding interactions in families with parents with BED.     

Family Exploration: The Contribution of Stability and Change Processes

Building upon the redefinition of exploration as a family process, this study analyses how the processes of family stability and change may favour exploration by members of multiple family relational contexts. Sixty non-clinical family triads (mother, father, child) participated in an experimental observational study and were video-recorded while playing in different interactive configurations. The children (37 females and 23 males) were 4–5 years old (M?=?55 months). The mothers’ ages ranged from 29 to 45 (M?=?38) and the fathers’ ages ranged from 29 to 46 (M?=?39). All the parents were employed and were living together. All participants were Caucasians of Italian nationality. Using the Triadic Interactions Analytical Procedure (TIAP), the family morphostatic processes and the family morphogenetic processes were analysed in relation to the family members’ exploration. Data analyses showed that family stability continual construction (morphostasis) and family change (morphogenesis) involve different interactive and relational dynamics (χ²(8)?=?13.84, p?>?.05; CFI?=?.97, TLI?=?.94, SRMR?=?.06), even if they are intertwined processes (p?<?.001). Both morphostatic and morphogenetic processes were correlated to the level of exploration showed by family members (respectively r?=?.32, p?<?.05, and r?=?.59, p?<?.001), even if the morphogenetic processes had a stronger relation with family exploration (z?=?1.85, p _one-tailed ?<?.05).
