Closing the neurology–psychiatry gap in tardive dyskinesia care in the Asia–Pacific region: consensus recommendations for educational initiatives to improve prevention, recognition, and shared care

Imagine a person taking medication to manage a serious mental health condition. The medicine helps them think clearly and feel stable, but over time, it causes an unwanted side effect: their face, lips, or tongue begin to move in ways they cannot control. These involuntary movements are not a sign that the mental illness has returned; they are a physical reaction to the drug itself. In the medical world, this condition is known as tardive dyskinesia. It is a preventable problem, yet it often goes unnoticed until it becomes severe, leaving patients struggling with movements that can be embarrassing, painful, and difficult to stop. The challenge is that the doctors who prescribe the medication are often specialists in the mind, while the doctors who treat movement disorders are specialists in the body. These two groups of experts frequently work in separate worlds, rarely speaking to one another, which means the patient often falls through the cracks.

A new set of recommendations from a group of doctors across the Asia-Pacific region aims to bridge this gap. The authors, who include both psychiatrists and neurologists from Thailand, Japan, South Korea, and China, have come together to propose a unified way of teaching and treating this condition. Their work suggests that the current system, where care is split between two disciplines, is failing patients. Instead, they argue for a shared approach where doctors from both fields learn from each other, starting from their very first days of medical school and continuing throughout their careers. The goal is simple: to ensure that every doctor, regardless of their specialty, can recognize the early signs of these involuntary movements, understand the risks of the medications that cause them, and know exactly when to call a colleague for help.

The problem is widespread and often hidden. Tardive dyskinesia is caused by drugs that block dopamine, a chemical in the brain that helps control movement. While these drugs are essential for treating conditions like schizophrenia and bipolar disorder, they can sometimes trigger these unwanted movements. In many parts of the world, newer medications that carry a lower risk are available, but in the Asia-Pacific region, access varies greatly. Furthermore, the condition is often missed because patients may not realize their movements are a side effect, or they may be too embarrassed to mention them. In some Asian countries, the widespread use of face masks can also hide the tell-tale signs of facial twitching, making it even harder for doctors to spot the problem during a routine visit.

The researchers found that the way doctors are trained contributes significantly to this issue. Psychiatrists, who are usually the first to prescribe the medication, often receive very little training on how to spot movement disorders. They may not know how to use specific tools to measure the severity of the movements or may not realize that a simple change in the medication could help. On the other hand, neurologists, who are experts in movement, often do not see these patients until the condition is advanced. They may be less familiar with the complexities of the mental illness that requires the medication in the first place, making them hesitant to suggest changes that could upset the patient's mental stability. This disconnect means that patients often wait too long for the right kind of help, and the condition can become permanent.

To fix this, the group of experts has proposed a detailed plan for education that brings psychiatrists and neurologists together. They suggest that medical students and residents should not just learn about their own specialty in isolation. Instead, they should participate in joint training sessions where they learn to manage patients with both mental and movement issues side by side. This would involve shared classroom time, joint case discussions, and even working together in the clinic under the supervision of mentors from both fields. The idea is to build a habit of collaboration early on, so that when a doctor encounters a patient with these symptoms, they instinctively know to reach out to a colleague rather than trying to solve the problem alone.

The recommendations also call for a change in how doctors think about the condition. It is not enough to just treat the symptoms; doctors need to understand the whole picture. This includes knowing which patients are at the highest risk, how to talk to them about the side effects without causing fear, and how to monitor them regularly. The authors emphasize that doctors should not blame themselves if a patient develops these movements, as the medications are often necessary for the patient's survival. Instead, the focus should be on shared responsibility, where the entire medical team works together to prevent the condition or manage it effectively if it does occur.

A key part of this new approach is the creation of clear pathways for when a doctor should refer a patient to a specialist. Currently, referrals often happen too late, only when the movements are severe or confusing. The new guidelines suggest that a referral should happen much earlier, as soon as there are new or troubling movements, or if the doctor feels unsure about how to proceed. This early connection allows for a quicker diagnosis and a better chance of reversing the symptoms before they become permanent. The plan also includes developing educational materials in local languages, recognizing that English-only resources are not enough for the diverse populations across Asia. These materials would help doctors in remote areas access the same knowledge as those in major cities.

The authors are careful to note that their recommendations are based on the collective experience and expertise of eight doctors who have worked together in this field. They acknowledge that these are proposals, not proven facts from a large-scale clinical trial, but they argue that the need for change is urgent. The current system is fragmented, and patients are suffering as a result. By aligning the knowledge and skills of psychiatrists and neurologists, the region can create a safety net that catches these problems early. The ultimate goal is to ensure that no patient has to choose between their mental health and their physical well-being, and that the doctors treating them are equipped to handle both with confidence and care.

This work represents a significant step forward in how medical care is organized in the region. It moves away from the idea that a doctor must be an expert in everything, and instead embraces the power of teamwork. By teaching doctors to work together, the recommendations aim to create a system where the right expertise is available at the right time. The proposed framework covers everything from the first day of medical school to the ongoing training of experienced specialists, ensuring that the lessons learned today will shape the care of tomorrow. If these ideas are adopted, they could transform the lives of countless people who currently live with the burden of these preventable movements, offering them a future where their treatment is safe, effective, and coordinated.
