[Stereotaxic brain operations in erethitic imbecility (author's transl)]

Area of Science:

• Neurosurgery
• Psychiatry
• Neurology

Background:

• Severe erethitic (aggressive-destructive) imbecility presents significant behavioral challenges.
• Limited effective long-term therapeutic options exist for this condition.

Purpose of the Study:

• To evaluate the long-term efficacy of stereotaxic thalamotomy in patients with severe erethitic imbecility.
• To assess the impact of surgical intervention on patient behavior and long-term outcomes.

Main Methods:

• Stereotaxic thalamotomy targeting the dorsomedial nucleus and internal medullary lamina of the thalamus.
• Bilateral electrocoagulation of target areas in 23 patients.
• Evaluation of long-term behavioral changes and outcomes, including pneumoencephalography.

Main Results:

• Over 75% of patients experienced a positive effect, with 50% achieving definite tranquilization and 27% showing acquiescence.
• Long-term outcomes included a "static course" (25%), an "undulant course" with improvement and stabilization (50%), and no improvement (25%).
• Observed pneumoencephalographic changes included increased thalamic height and decreased ventricular width.

Conclusions:

• Stereotaxic thalamotomy is a therapeutic method with 75% long-term effectiveness for erethitic imbeciles.
• The procedure should be considered a proven therapeutic alternative for managing severe aggressive-destructive behaviors.
• Adjunctive therapies like psychopharmacotherapy and occupational therapy may support surgical outcomes.
