Tics can be reduced and often well-controlled through a combination of behavioral therapy, medication, and lifestyle adjustments, though completely eliminating them isn’t always realistic. For many children, tics fade significantly or disappear entirely by adulthood. For those whose tics persist and interfere with daily life, the most effective first-line treatment is a specific type of behavioral therapy called habit reversal training, sometimes paired with medication.
Why Tics Happen in the First Place
Tics originate in a circuit connecting deep brain structures to the motor cortex. Normally, a set of brain regions called the basal ganglia act as a gatekeeper, selectively releasing certain movements while keeping others suppressed. In people with tic disorders, excess dopamine in a key part of this circuit (the striatum) disrupts the gatekeeper function. The result is an unwanted “release” of motor patterns, meaning movements or sounds fire off without being intentionally triggered.
This is why tics feel semi-voluntary. Most people with tics describe a building urge right before one happens, similar to the urge to sneeze. You can hold it back briefly, but the pressure builds until it releases. Understanding this sensation is actually central to the most effective treatment.
Habit Reversal Training
Habit reversal training, or HRT, is the behavioral therapy with the strongest evidence for reducing tics. It’s a core component of a broader approach called Comprehensive Behavioral Intervention for Tics (CBIT), and it works by teaching you to recognize the urge that precedes a tic and then perform a “competing response” that physically prevents the tic from completing.
The therapy has three main steps. First, you build awareness of the specific tic and the sensation that comes just before it. Many people tic without fully noticing, so this step alone can change the pattern. Second, you learn a competing response: a deliberate movement or muscle contraction that blocks the tic. This replacement behavior needs to be something you can hold for at least a minute, something that looks normal to others, and something you can do anywhere without needing a prop. For a head-jerking tic, that might mean gently tensing your neck muscles in a neutral position. For a shoulder-shrugging tic, it could be pressing your arms down against your sides. Third, the therapist helps you practice the competing response in situations where tics are most likely to occur.
CBIT typically involves eight sessions over about ten weeks. It doesn’t cure tics permanently, but it gives you a reliable tool to reduce their frequency and intensity, often by 30 to 50 percent.
Medications That Reduce Tics
When tics are moderate to severe and behavioral therapy alone isn’t enough, medication can help. Only three drugs are FDA-approved specifically for tics: haloperidol, pimozide, and aripiprazole. All three work by blocking dopamine receptors, which addresses the excess dopamine activity driving the tic circuit. They’re effective, but they carry a significant side-effect burden, including weight gain, drowsiness, and movement-related side effects like stiffness or restlessness.
Because of those side effects, many doctors start with off-label options that are gentler. Clonidine and guanfacine, originally developed for high blood pressure, are moderately effective at reducing tics and tend to be much better tolerated. They work through a different mechanism, calming the norepinephrine system rather than blocking dopamine directly. These are often the first medications tried, especially in children.
A newer class of drugs called VMAT2 inhibitors is gaining attention. These medications reduce dopamine signaling from a different angle: instead of blocking the receptor where dopamine lands, they limit how much dopamine gets packaged and released in the first place. Early evidence suggests they can match the effectiveness of traditional antipsychotics without causing the same degree of weight gain. Some clinicians are already using them off-label for tics, and research into combining low-dose antipsychotics with VMAT2 inhibitors suggests the pairing could maintain tic control while lowering overall side effects.
Supplements With Actual Evidence
Two supplements have clinical trial data supporting their use for tics: magnesium and vitamin B6. In a randomized, double-blind trial of children aged 7 to 14 experiencing tic flare-ups, daily magnesium supplementation cut tic counts roughly in half compared to a control group. The magnesium group’s average total tic count dropped to 12.9, versus 26.7 in the control group.
Vitamin B6 shows similar promise. A double-blind trial found that daily B6 supplementation reduced both motor and vocal tics in children, with average tic severity scores dropping by about 43 percent. A separate study combining magnesium and B6 over 90 days showed progressive tic reduction, with overall severity scores falling from 58.1 to 18.8. These aren’t miracle cures, but the effect sizes are meaningful, and the side-effect risk is low. Both supplements appear most helpful during periods when tics are flaring up.
Stress, Sleep, and Daily Triggers
The conventional wisdom is that stress makes tics worse, but the reality is more nuanced. In an experimental study that measured tics in children during induced stress, relaxation, and concentration tasks, tics were actually lowest during acute stress and highest during relaxation. The likely explanation: when your brain is intensely focused or flooded with adrenaline, it temporarily suppresses the tic circuit. The tics then rebound when you relax afterward.
This matters practically. If you notice tics spike when you finally sit down after a long day, it’s not that relaxation causes tics. It’s that the suppression lifts. The broader pattern of tic “waxing and waning” over weeks and months is well documented but still not fully understood. What does help is maintaining consistent sleep, since fatigue is one of the most commonly reported triggers for worse tic periods, and reducing chronic background stress through regular exercise and structured downtime.
When Tics Don’t Respond to Standard Treatment
For the small percentage of people whose tics remain severe despite therapy and multiple medications, deep brain stimulation (DBS) is an option. This involves surgically implanting electrodes in the thalamus, one of the relay stations in the tic circuit, to regulate the abnormal signaling. In a study of 18 patients with treatment-resistant Tourette syndrome who received bilateral thalamic DBS, all showed significant reduction in tic severity at two-year follow-up. Beyond tics, 15 of the 18 patients also experienced improvements in anxiety, depression, and overall quality of life.
DBS is reserved for cases where tics cause serious disability and nothing else has worked. The surgery carries standard neurosurgical risks, and the implanted device requires ongoing adjustments. But for people who qualify, the outcomes are consistently positive.
Provisional Tics vs. Tourette Syndrome
Not all tics need aggressive treatment. If tics have been present for less than a year, the diagnosis is provisional tic disorder, and many of these cases resolve on their own, especially in children. Tourette syndrome requires at least two motor tics and one vocal tic persisting for a year or more. The distinction matters because it determines how urgently you need to pursue treatment. A child who started blinking or throat-clearing a few months ago may simply outgrow it. If tics persist beyond a year and interfere with school, social life, or comfort, that’s when the full treatment toolkit becomes relevant.
