Gender, aggression and serotonergic function are associated with response to sertraline for behavioral disturbances in Alzheimer's disease
Bibliographic record
Abstract
BACKGROUND: Indications for serotonergic medications in the treatment of behavioral disorders associated with Alzheimer's disease (AD) remain to be established. METHOD: Sertraline (100 mg OD) was evaluated in a double-blind, randomized, placebo-controlled cross-over study in 22 nondepressed patients with severe probable AD and significant behavioral disturbance. Each subject was given a fenfluramine challenge to evaluate central serotonergic tone. RESULTS: Eight of 21 (38%) completers responded to sertraline. Drug responsive behaviors included aggression/agitation, irritability and aberrant motor behavior. Low aggression, female gender and large prolactin increase were associated with a better response. There was a trend for decreased aggression during sertraline versus placebo (p = 0.08). CONCLUSION: Aggression, gender and serotonergic function were associated with sertraline response. Larger randomized controlled trials are needed to clarify the profile of responders.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
