A prospective evaluation of open prefrontal leucotomy

Area of Science:

• Neurosurgery
• Psychiatry
• Psychology

Background:

• Severe and intractable psychiatric illnesses pose significant treatment challenges.
• Open prefrontal leucotomy has been used as a treatment option for such conditions.

Purpose of the Study:

• To evaluate the efficacy and safety of open prefrontal leucotomy for severe psychiatric illnesses.
• To compare outcomes with alternative psychosurgery techniques.

Main Methods:

• An open prefrontal leucotomy procedure was performed on 43 patients.
• Patient outcomes were assessed over a six-month follow-up period.
• Standardized psychological scales (Hamilton Anxiety, Hamilton Depression, Beck Depression, Eysenck Personality Inventory) were used for evaluation.

Main Results:

• Mortality rate was 6.9% (3/43), with adverse events including personality changes (3 patients) and seizures (1 patient).
• Clinical improvement was observed in 57.5% (marked) and 30.0% (mild to moderate) of 40 followed patients.
• Significant reductions in anxiety, depression, and neuroticism scores were noted post-operation.
• Extroversion scores significantly increased after the procedure.

Conclusions:

• Open prefrontal leucotomy demonstrated significant clinical improvement in a majority of patients but carried substantial risks.
• Stereotactic or electrode implantation techniques are suggested as safer alternatives.
• Psychosurgery should be centralized in specialized units for improved safety and outcomes.
