In this video, Dr. Casey Halpern discusses the biology of compulsive eating and behaviors, how to treat them with deep brain stimulation, and how OCD may be related. She emphasizes that as a neurosurgeon, she is obligated to better understand the origins of OCD and how to treat it.

00:00:00 Today's podcast is about the latest research on eating disorders and obsessive-compulsive behaviors, and how brain surgery and other treatments are being developed to help people. Dr. Casey Halpern is the chief of neurosurgery at the University of Pennsylvania School of Medicine and his laboratory focuses on bulimia binge eating disorder and other forms of obsessive-compulsive behaviors. They embrace pharmacologic and behavioral and talk therapy interventions, but their main focus is the development and application of engineered devices to go directly into the brain and stimulate the neurons. This is an area of neuroscience that is going to expand in the years to come.
00:05:00 Neurosurgeons are experts in surgeries that involve the stimulation of specific areas of the brain. Casey Halpern is a neurosurgeon who has spent a lot of time studying the brain and its functions. He is also a nurse surgeon, which means that he has a deep understanding of the way the body works as a whole.
00:10:00 Dr. Casey Halpern is a neurosurgeon who specializes in treating compulsive eating and behaviors with deep brain stimulation and focus ultrasound. He has observed that some of the information in textbooks about the brain is incorrect, and that by stimulating certain regions of the brain, one can cause temporary side effects like laughter or panic.
00:15:00 Dr. Casey Halpern discusses the biology of compulsive eating and behaviors, how to treat them with deep brain stimulation, and how OCD may be related. She emphasizes that as a neurosurgeon, she is obligated to better understand the origins of OCD and how to treat it.
00:20:00 Dr. Casey Halpern discusses how deep brainstimulation surgery can be used to treat obsessive-compulsive disorder (OCD). She discusses the risks and benefits of the surgery, and notes that there is still about a third of patients who suffer from OCD. She recommends exposure response prevention (ERP) as one of the most effective treatments for OCD.
00:25:00 The video discusses how neuroimaging studies have found that areas of the cortex, specifically the frontal lobe, are dysregulated in patients with OCD, and suggest that treating the disorder with stimulations to these areas may be more effective than simply treating the symptoms. research is still in its early stages, and it is important to approach animal models of OCD thoughtfully in order to identify potential treatment options.
00:30:00 Dr. Casey Halpern discusses the similarities and differences between obsessive-compulsive disorder (OCD) and addiction, and how superstition and compulsion can play a role in the crossover between the two conditions. He also discusses a personal anecdote in which he developed a superstition around knocking on wood while studying and found that the compulsion went away when he stopped taking a stimulant.
00:35:00 The video discusses the role of the nucleus accumbens in healthy brain behavior, and how it may be involved in compulsion and reward addiction.
00:40:00 In this video, Dr. Casey Halpern discusses the role of the nucleus accumbens in reward behavior. He highlights the importance of distinguishing between normal urges and those that pose a risk to oneself or others. He also discusses the role of obesity in the development of eating disorders. Finally, he discusses the potential benefits of using deep brain stimulation to target this area in patients with obesity-related problems.
00:45:00 The Huberman Lab video discusses common to eating disorders and obesity, and how exposure to a high fat diet can disrupt normal function in a mouse's nucleus accumbens, leading to uncontrolled behavior. The goal of a human trial is to restore normal function to the same circuit in people with binge eating disorder.
00:50:00 In this video, Dr. Casey Halpern discusses the prevalence of compulsive eating and behaviors, and how these disorders may be related to anxiety disorders. He also discusses the different symptoms that may be present in individuals with compulsive eating and disorders, and how to determine if a brain area is being affected by the disorder.
00:55:00 In this video, Dr. Casey Halpern discusses how eating disorders may develop and how a predisposition to unhealthy eating coupled with a stressful life can lead to an eating disorder. Halpern also discusses how a concussion may lead to an eating disorder, noting that the two hits of a predisposition and a stressor are often cumulative.

01:00:00 - 02:00:00

In this video, Dr. Casey Halpern discusses the biology and treatments for compulsive eating and behaviors, including how the nucleus accumbens is involved in these behaviors and how non-invasive brain stimulation can be used to treat them. He also discusses the potential risks and benefits of these treatments.

01:00:00 The first step in treating compulsive eating and behaviors is understanding the underlying biology. A study has been approved for research to study how the nucleus accumbens is involved in these behaviors.
01:05:00 The video discusses how, in the case of Parkinson's disease, the tremors that patients experience are thought to be caused by a disruption in a circuit in the brain called the nucleus accumbens. This circuit is related to cravings and obsessions, so by stimulating this area, a Tremor can be induced and the cravings will dissipate. This is one of the goals of a clinical trial being conducted by the researchers, which is to identify where in the brain these craving cells are located.
01:10:00 The Huberman Lab studies how to stop compulsive eating and behaviors by identifying craving cells and triggering stimulation only when they are present.
01:15:00 The video discusses the challenges of treating compulsive eating and behaviors, and how certain brain vulnerabilities might be more similar than different. The video also discusses how anorexics and people with obesity may share similar compulsions, and how this might be due to societal pressures.
01:20:00 Dr. Casey Halpern discusses the use of non-invasive brain stimulation and blocking activity in the brain to treat anorexia nervosa and other psychiatric conditions. She discusses the current state of the technology and how it is being used to treat these conditions. She also discusses the potential risks and benefits of these treatments.
01:25:00 In this video, Dr. Casey Halpern discusses how surgery and non-invasive treatments for compulsive eating and behaviors can be minimally invasive. He also discusses how TMS (transcranial magnetic stimulation) is FDA approved for depression and nicotine addiction and how it is being used in an invasive trial to try to pull patients from a previous TMS trial.
01:30:00 In this video, Dr. Casey Halpern discusses how recent advances in neuroscience have allowed for the exploration of how the human brain works, with particular focus on how to treat conditions like compulsive eating and behaviors. She also discusses how ultrasound may be a useful tool in treating these conditions.
01:35:00 Dr. Casey Halpern, a champion for compulsive eating and behaviors, discusses the use of focus ultrasound in the treatment of these conditions. He notes that without FDA approval, these treatments are still experimental and that more work needs to be done to determine where best to target treatments. He also talks about epilepsy and how stereotactic brain surgery using tiny electrodes can be used to study mental health disorders.
01:40:00 In this video, Dr. Casey Halpern discusses the importance of awareness in treating compulsive eating and behaviors, and how it can be improved with pre-behavioral states. He also discusses how pharmacologic treatments work due to their systemic impact. Finally, he highlights the problem of resistant patients, and how awareness can be a powerful tool in overcoming them.
01:45:00 The video introduces a technology called a "mood provocation device," which is used to help patients with compulsive eating and other behaviors. The device detects signals related to cravings and bingeing, and can be used to help patients understand their behavior and predict when they are most likely to engage in harmful behaviors. The technology is still in its early stages, but has the potential to play a role in the treatment of compulsive eating disorders.
01:50:00 In this YouTube video, Dr. Casey Halpern explains the biology and treatments for compulsive eating and behaviors, including how impulsivity is related to overeating and how exercise can help to counteract these impulses. He also discusses the importance of hand-motor activity and how neurosurgeons avoid activities that could injure them.
01:55:00 Dr. Casey Halpern discusses how calm neurosurgeons may be due to their training, and how this trait may be advantageous in their profession. He also discusses how resistance training can help protect muscles from deterioration and improve skeletal function.

02:00:00 - 02:10:00

The video discusses how neurosurgery residents experience high stress and long hours, which can lead to unhealthy habits such as overeating. The speaker recommends self-care measures such as exercise and good sleep habits, and states that these have helped him in the past and will continue to do so in the future.
