Abstract

fetched live from OpenAlex

Introduction Diagnosis of behaviors in advanced neurocognitive disorders (aNCD) is one of exclusion, and the framework has been laid out in DSM-V. However, clinical assessments in aNCD become increasingly unreliable, and commonly used psychometric tools for clinical assessments lack reliability and validity, thereby making outcomes unreliable. Consequently, the syndromic and symptom management approaches for behaviors in aNCD behaviors have yielded poor results. To address this, the focus has shifted towards understanding the ‘meaning’ of behaviors in aNCD, recognizing them as a ‘mode of communication’. To date, there are no existing frameworks to ascribe ‘meaning’ to behaviors in aNCD. Objectives LuBAIR™ paradigm is the first step in offering such a framework for understanding the ‘purpose’ and ‘meaning’ of behaviors in NCD. The ‘meaning’ ascribed to each behavioral category was used to guide the use of atypical antipsychotics in their management. De-prescribing was attempted on patients who qualified to enter this retrospective study. De-prescribing was defined as successful if individuals were completely withdrawn from AAP and remained off them for 60 days without the re-emergence of behaviors. Methods The data collected on the second occasion, in the successful and failed de-prescribed groups, were compared in this retrospective study. MANOVA, Chi-Square paired t-test statistical analyses were used to detect the differences in the behavioral categories between the two cohorts. Cohen d was used to measure effect size. Results Patients who did not have Mis-Identification and Goal-Directed Expressions were more likely to successfully de-prescribe: X2 (1, N = 40) = 29.119 p < 0.0001 and X2 (1, N = 40) = 32.374, p < 0.0001, respectively. Alternatively, the same behavioral categories were more likely present in patients who failed de-prescribing: MANOVA and paired t-test (p < 0.0001). Atypical antipsychotics, in their role as an antipsychotic and mood stabilizer, may be used to manage Mis-Identification and Goal-Directed Expressions, respectively. Conclusions LuBAIR paradigm has the potential to guide the development of specific behavioral care plans and the use of AAP in managing individual behavioral categories. AAP use can be justified for managing Misidentification and Goal-Directed Expressions. Vocal expressions may warrant the use of AAP, pending further study. The LuBAIR paradigm offers guidance for de-prescribing AAP for all other behavioral categories in the LuBAIR Inventory. This study is also a preliminary step in validating the psychological theories used to support the individual categories. This workshop will educate the participants on the LuBAIR paradigm and its application in developing person-centered interventions for behaviors in a NCD. Disclosure of Interest None Declared

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
