Our Summary
This research paper discusses the use of two types of neurosurgery – bilateral anterior capsulotomy and deep brain stimulation of the nucleus accumbens – as experimental treatments for severe anorexia nervosa, a type of eating disorder that is resistant to other treatments. The study looked at brain scans of patients before they had these surgeries between 2019 and 2023, to see if there were any differences between them and healthy controls, and to see if any specific brain areas were linked to changes in body mass index (BMI) after the surgery.
The study found that, on average, patients’ BMI increased significantly after surgery, which suggests that these surgical treatments can help severely anorexic patients gain weight. The brain scans revealed that patients with anorexia nervosa had smaller volumes of gray matter in several areas of the brain compared to healthy controls.
The researchers also found links between the volume of certain brain areas and changes in BMI after surgery. However, these links were not strong enough to survive correction for multiple comparisons, meaning they could be due to chance.
In conclusion, the study suggests that these types of neurosurgery can help patients with severe anorexia nervosa to gain weight. The researchers also suggest that the structure of certain brain areas may influence the increase in BMI after surgery, although more research is needed to confirm this. The research could also potentially help to predict which patients will respond best to these surgical treatments.

Doctor’s Tip
One helpful tip a doctor might tell a patient about brain surgery is to follow all post-operative care instructions carefully to ensure a successful recovery. This may include taking prescribed medications, attending follow-up appointments, and avoiding certain activities that could impact the healing process. It is also important to communicate any concerns or changes in symptoms to your healthcare team promptly.
Suitable For
Overall, patients who are typically recommended for brain surgery are those who have conditions that are resistant to other forms of treatment and are significantly impacting their quality of life. In the case of this study, patients with severe anorexia nervosa who have not responded to traditional therapies were considered for bilateral anterior capsulotomy and deep brain stimulation of the nucleus accumbens.
It is important to note that brain surgery is a highly invasive and risky procedure, so patients must undergo a thorough evaluation process to determine if they are suitable candidates. This evaluation process typically involves a comprehensive assessment of the patient’s medical history, current symptoms, and imaging studies to identify the specific areas of the brain that may be causing the symptoms.
In general, patients with conditions such as brain tumors, epilepsy, movement disorders (such as Parkinson’s disease), and certain psychiatric disorders (such as severe depression or obsessive-compulsive disorder) may be recommended for brain surgery if other treatments have not been effective.
Ultimately, the decision to undergo brain surgery is made on a case-by-case basis, taking into consideration the individual patient’s unique circumstances, risks, and potential benefits of the procedure. It is important for patients to work closely with a multidisciplinary team of healthcare professionals, including neurosurgeons, psychiatrists, and other specialists, to determine the best course of treatment for their specific condition.
Timeline
Before brain surgery, a patient typically undergoes a series of evaluations and tests to determine the best course of treatment. This may include physical exams, neurological exams, imaging tests such as MRI or CT scans, and psychological evaluations. The patient and their medical team will discuss the risks and benefits of the surgery, as well as potential alternative treatments.
After brain surgery, the patient will typically stay in the hospital for a period of time to recover and be monitored for any complications. They may experience pain, swelling, and changes in cognitive function. Physical therapy and rehabilitation may be recommended to help the patient regain strength and function. The patient will have follow-up appointments with their medical team to monitor their progress and make any necessary adjustments to their treatment plan.
Overall, the timeline of a patient’s experience before and after brain surgery can vary depending on the specific procedure and individual circumstances. It is important for patients to follow their healthcare provider’s recommendations and communicate any concerns or changes in symptoms during their recovery process.
What to Ask Your Doctor
