Stereotactic lesioning combined with long-term Risperidone maintenance for life-threatening refractory suicidal command hallucinations in major depressive episode with psychotic features: a case report.
Article in BMC psychiatry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundRefractory suicidal command hallucinations in major depressive episode with psychotic features constitute an acute clinical emergency, often unresponsive to multiple antipsychotics and electroconvulsive therapy (ECT), leaving clinicians with limited life-saving options. Stereotactic lesioning, as a last-resort intervention, may have some utility in such case; however, its long-term efficacy and the extent to which it depends on postoperative pharmacotherapy are not yet fully understood. CASE PRESENTATION: A 20-year-old female with major depressive episode with psychotic features experienced 10-12 daily suicidal command hallucinations (with 4 suicide attempts within 1 week), refractory to 3 antipsychotics (Aripiprazole, Olanzapine, Risperidone) and 12 sessions of ECT (Montgomery-Asberg Depression Rating Scale [MADRS]: 30, Hoffman auditory hallucination score [Hoffman]: 25). Stereotactic bilateral lesioning of the anterior limb of the internal capsule and cingulate gyrus (SALIC-CG) resulted in a marked alleviation of symptoms within 1 week (MADRS: 7, Hoffman: 0). Notably, symptoms recurred 1 month postoperatively following antipsychotic discontinuation (MADRS: 22, Hoffman: 20) but resolved rapidly upon reintroducing Risperidone, with sustained remission at 6 months (MADRS: 6, Hoffman: 0) under continuous pharmacotherapy.
conclusionsThis case offers preliminary evidence that stereotactic lesioning may act as a key intervention for alleviating symptoms in patients with psychotic major depressive episode-specifically those with intractable suicidal command hallucinations that do not respond to all conventional treatments. Critically, it underscores that postoperative long-term antipsychotic maintenance is not merely adjunctive but essential to preserve surgical benefits, establishing a "surgery + long-term pharmacotherapy" paradigm with direct implications for managing high-risk refractory cases. CLINICAL TRIAL NUMBER: It is not a clinical trial, clinical trial number: not applicable.
