Tardive Dyskinesia (TD) is a neurological syndrome characterized by involuntary, repetitive movements. It develops after prolonged exposure to certain medications, most commonly those that block dopamine receptors, and may manifest months or even years after starting a drug. The movements often involve the face (such as lip smacking, grimacing, or tongue thrusting), but can also affect the limbs and trunk. Finding the right medical professional is important for managing this condition.
The Doctors Who Identify Tardive Dyskinesia
Psychiatrists are the physicians who frequently first recognize the signs of Tardive Dyskinesia, as the condition is most commonly associated with the long-term use of antipsychotic medications. These drugs are prescribed to manage psychiatric disorders like schizophrenia and bipolar disorder. Other mental health prescribers and primary care providers who manage patients on certain anti-nausea or antidepressant medications may also encounter TD.
Because the onset of TD is often subtle, regular monitoring is a necessary part of ongoing medication therapy. Clinicians use standardized tools like the Abnormal Involuntary Movement Scale (AIMS) to screen for and track the severity of these movements. The AIMS evaluates orofacial, extremity, and truncal movements, helping to objectively assess for dyskinesia. This routine assessment by the prescribing physician is crucial for early detection, which can help lessen the condition’s severity.
The Specialists Who Treat Movement Disorders
When involuntary movements are confirmed, the specialist for treatment is a Neurologist, particularly one with subspecialty training in Movement Disorders. A Movement Disorder Specialist (MDS) completes an additional one to two years of fellowship training, focusing on complex involuntary movement conditions. This specialized expertise is important for accurately diagnosing TD and differentiating it from other movement disorders that may present similarly.
The MDS confirms the diagnosis, rules out other neurological conditions such as Huntington’s disease, and formulates a targeted treatment plan. They are knowledgeable about the latest advancements in TD treatment, specifically the use of selective vesicular monoamine transporter 2 (VMAT2) inhibitors. Medications like valbenazine and deutetrabenazine regulate dopamine activity to reduce the involuntary movements characteristic of TD. The specialist guides the initiation and titration of these therapies to achieve symptom control.
Coordinating Care for Long-Term Management
The management of Tardive Dyskinesia requires collaboration between the psychiatrist and the movement disorder specialist. The psychiatrist focuses on maintaining stability for the underlying psychiatric condition that necessitated the original medication. The neurologist or MDS simultaneously manages the movement disorder itself. This dual focus ensures that treating the dyskinesia does not destabilize the patient’s mental health.
Collaboration is important when adjusting the psychiatric medication regimen. While discontinuing the causative medication is often considered, an abrupt stop can sometimes worsen TD symptoms or lead to a relapse of the psychiatric illness. The psychiatrist and the movement specialist work together to determine the most balanced approach for the patient, whether it involves a gradual taper, a switch to a different class of medication, or the addition of a VMAT2 inhibitor. This integrated approach is the foundation for successful long-term outcomes.
