Bilateral hypothalamotomy plus dominant amygdalotomy with Gamma Knife radiosurgery. A non-invasive alternative when everything has failed in the management of aggressive behavior disorder.
Article in Surgical neurology international, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Background: Impulsive aggression is the core symptom of intermittent explosive disorder, which can be a feature of several psychiatric disorders. There is a subset of individuals who do not respond adequately to medical treatment; they are treatment refractory. The objective of this report is to describe a case of a patient with a background of schizophrenia and concomitant refractory aggressiveness disorder, treated with two-stage bilateral hypothalamotomy and unilateral amygdalotomy with Gamma Knife radiosurgery (GKR). Case Description: A 36-year-old male presented with a background of paranoid schizophrenia. Episodes of self- and hetero-aggressiveness were present at the initial diagnosis. High dosages of psychotropic medication were taken, and 70 sessions of electroconvulsive therapy were performed; however, no adequate response was obtained. Bilateral hypothalamotomy plus left amygdalotomy through GKR was performed. After 25 months of follow-up, a marked decrease in the frequency, degree, severity of aggressiveness and the requirement for psychotropic medications was observed. Conclusion: Hypothalamotomy plus amygdalotomy with Gamma Knife may be an effective ablative technique for the management of refractory aggressive disorder in patients with mental illness.
