Premonitory Urge and Tic Severity, Comorbidities, and Quality of Life in Chronic Tic Disorders

BACKGROUND: Tics are intimately associated with premonitory urges (PU) but knowledge about urges is still limited, with small sample sizes often limiting the generalizability of findings. OBJECTIVES: This study addressed the following open questions: (1) is tic severity associated with urge severity, (2) how common is relief, (3) which comorbidities are associated with urges, (4) are urges, tics, and comorbidities associated with lower quality of life, and (5) can complex and simple, motor and vocal tics be differentiated based on PU? METHODS: N = 291 patients who reported a confirmed diagnosis of chronic primary tic disorder (age = 18–65, 24% female) filled out an online survey assessing demographic data, comorbid conditions, location, quality and intensity of PU, as well as quality of life. Every tic was recorded, and whether the patient experienced a PU, the frequency, intensity, and quality of that urge. RESULTS: PU and tic severity were significantly associated, and 85% of urge‐related tics were followed by relief. A diagnosis of attention deficit/hyperactivity disorder (ADHD) or depression, female gender, and older age increased the likelihood of experiencing PU, while more obsessive compulsive (OCD) symptoms and younger age were associated with higher urge intensities. PU, complex vocal tics, ADHD, OCD, anxiety, and depression were related to lower quality of life. Motor and vocal, complex and simple tics did not differ regarding PU intensity, frequency, and quality, or relief. CONCLUSIONS: The results shed light on the relationship between PU, tics, comorbidities, age, gender, and quality of life in tic disorders.
