Teva Study Finds Only 23% of Younger Adults with Mood Disorders and Tardive Dyskinesia (TD) Symptoms Are Formally Diagnosed with TD Despite Widespread Impact

• New analysis from the IMPACT-TD Registry confirms tardive dyskinesia (TD) causes a significant burden for most individuals with concomitant mood disorders, impacting their lives regardless of age
• The data shows that 85% of young adults with mood disorders living with TD movements, ages 18-29 (n=13), experience moderate to severe TD impact, yet only 23% received a formal diagnosis of TD, revealing a gap in disease identification
• Teva is dedicated to advancing research and initiatives that deepen clinical understanding, identify diagnostic gaps and improve outcomes for patients with TD
  
  
  
  

PARSIPPANY, N.J. and TEL AVIV, Israel, May 18, 2026 (GLOBE NEWSWIRE) -- Teva Pharmaceuticals, a U.S. affiliate of Teva Pharmaceutical Industries Ltd. (NYSE and TASE: TEVA), today announced new data from the ongoing, real-world IMPACT-TD Registry, highlighting a significant gap in diagnosing tardive dyskinesia (TD) in patients with underlying mood disorders. While the findings demonstrate that most patients across all age groups experience multidimensional impact from the condition, young adults (aged 18-29, n=13) had the lowest rate of formal diagnosis (23%) despite having one of the highest rates of personal impact (85%). The data were presented at the 2026 American Psychiatric Association Annual Meeting, taking place May 16 – 20, 2026 in San Francisco, California.

"The latest data from the IMPACT-TD Registry underscores the profound, multidimensional impact of tardive dyskinesia on individuals, extending far beyond any single demographic. Despite its widespread impact, we are still confronted with meaningful diagnostic gaps, leaving many patients undiagnosed and untreated," said Verena Ramirez Campos, MD-MBA, Vice President U.S. Medical Affairs and Global Innovative Strategy at Teva. "We are committed to grasping the complete human experience of TD, and working to help close those gaps and bring forth innovations that make a meaningful difference in the day-to-day lives of people living with TD."

The IMPACT-TD Registry, the largest TD study to date, is a 3-year, prospective, non-interventional, Phase 4 study examining how TD progresses over time and the impact it has on patients' lives.^1-3 The study, which includes a broad representation of people affected by TD (age, sex, race/ethnicity, underlying conditions, movement severity and treatment status), evaluates 611 participants aged ≥18 years who, at enrollment, had either a score of ≥2 on at least one item of the Abnormal Involuntary Movement Scale (AIMS) and probable TD, or were receiving vesicular monoamine transporter 2 (VMAT2) inhibitor therapy for TD. The present analysis of the IMPACT-TD Registry evaluated 211 adults with TD who were not receiving VMAT2 inhibitor therapy at enrollment and had concomitant mood disorders, such as bipolar disorder (60%) or depression (54%), reflecting a diverse, real-world patient population. Multidimensional impact of TD was measured using the clinician-reported IMPACT-TD scale, while TD severity was assessed by AIMS.

The IMPACT-TD findings revealed:

• A majority of participants, regardless of age, reported a moderate to severe global impact from TD. This burden was particularly high for those aged 18-29 (85%) and 50-59 (87%, n=57), demonstrating that TD significantly affects daily life across the adult lifespan.
• The psychological impact of TD was most pronounced in adults aged <60. Over three-quarters (77%) of those aged 18-29 experienced moderate to severe psychological effects despite lower AIMS scores (6.4) on average compared to older adults aged 60-69 (8.4, n=56) and >69 (9.9, n=28).
• Despite the high impact, formal TD diagnosis rates were lowest among adults <40 years old. The rate was 23% for participants aged 18-29 and 35% for participants aged 30-39 (n=20), well below the peak of 57% seen in adults aged 40-49 (n=37) and 47% average in the 50+ age subgroups.
• A significant delay in diagnosis was also identified, with patients waiting an average of more than 3.5 years to be formally diagnosed after their involuntary movements were first recognized.
  
  
  
  

"Beyond the visible symptoms, tardive dyskinesia impacts every aspect of daily living, from personal independence to social interaction and emotional wellbeing," said Richard Jackson, MD, an Assistant Clinical Adjunct Professor in the University of Michigan School of Medicine's Department of Psychiatry and IMPACT-TD principal investigator. "What remains a critical unknown is how this debilitating condition uniquely impacts those already struggling with mood disorders, especially at different ages. The IMPACT-TD study is designed to bridge this crucial knowledge gap, giving us the insights we urgently need to offer targeted, meaningful support to every TD patient, no matter their background."

Teva is committed to assisting in addressing these significant diagnostic gaps, which could improve the lives of those living with tardive dyskinesia.
