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.
