Clients suffering from Borderline Personality Disorder show a high dropout rate in psychotherapy. The understanding of what occurs during the sessions between therapist and client suffering from this type of personality disorder may contribute to prevent future errors and failures, increasing chances of completing the therapeutic process and reducing drop-out probability. The current study had the objective of identifying the variables related to the dropout in a case of Borderline Personality Disorder. Participated a female behavioranalytic therapist, with 12 years of clinical experience and a female client, 30 years old, married, no children, with a college degree. 13 complete sessions were recorded in video, transcribed and categorized according to the Multidimensional System for Categorization of Behaviors in Therapeutic Interaction. A lag sequential analysis was carried out. Data of this study refer to the 9th through the 22nd sessions, although the 14 th session was excluded, since it was a couple session. Outcomes showed that the therapist"s categories in higher percentages were `Facilitation`, `Request of Report` and `Empathy` and the less frequent percentages were `Request of Reflection`, `Approval` and `Recommendation`. `Disapproval` was the therapist"s category appearing with lower frequency. Although `Interpretation` occurred in low frequency, it had a long duration. The client"s categories with higher percentages were `Report` and `Establishment of Relationship between Events`. The lower percentages of occurrences were: `Request`, `Agreement`, `Opposition` and `Improvement`. The category `Aims` did not occur at any time. Throughout the sessions a decrease in percentage of the client"s categories `Establishment of Relationship between Events` and an increase in "Report" were observed. At the same time a decrease in the therapist"s categories `Empathy`, `Request for Reflection` and `Interpretation` was noted. Sequences which occurred more frequently were `Report` followed by `Facilitation` and `Facilitation` followed by `Report`. The therapy drop-out seemed to be related to several factors: a) loss of opportunities by the therapist to approve, to request reflection and to interpret; b) lack of attention to reports on complaints of diseases, having an invalidation effect; c) therapist"s extended vacation and d) therapist"s refusal to attend an additional home session, in a critical moment, thus repeating the invalidation.

Anticholinergic burden has a significant impact on patients' ability to participate in and benefit from psychosocial treatment programmes. Physicians need to be mindful of the cumulative effect that medications can have on patient cognition, functional capacity and ability to benefit from psychosocial treatments.

O cenário da pandemia de COVID-19 representa um desafio sem precedentes para a sociedade. Em que pese a importância das medidas imediatas visando à prevenção da propagação da doença, cuidados com os indivíduos acometidos e medidas para minimizar os impactos econômicos e sociais, a abordagem de temas relacionados à saúde mental da população em geral é também crucial. As contribuições interdisciplinares relacionadas à saúde mental envolvem a compreensão dos mecanismos cognitivos e comportamentais que sustentam hábitos, atitudes e crenças. Essa compreensão é fundamental para maximizar a eficácia das estratégias que implicam em mudanças significativas na forma de comportar, conceber e planejar atividades quotidianas. O presente artigo discute abordagens da psiquiatria, psicologia e ciências relacionadas no manejo de questões relacionadas à mudança de comportamento, hábitos de nutrição e atividade física, trabalho e grupos etários vulneráveis.
