Tic Disorders

Tics are sudden, rapid, recurrent movements or vocalizations: blinking, grimacing, head jerking, shoulder shrugging, sniffing, throat clearing, or more complex sequences of movement and speech. When multiple motor tics and at least one vocal tic have been present for more than a year with onset before age 18, the diagnosis is Tourette syndrome. When tics occur in only one channel, movement or voice, the diagnosis is persistent motor or vocal tic disorder.

Tics typically begin in childhood and improve for many people by early adulthood, but they do not always fade on schedule. Adults who still have tics often carry them through their most demanding professional and social years, and they routinely discover that the clinics, therapists, and treatment programs built around childhood tics have little to offer them. Adult tic expertise is scarce, and patients are frequently told, in effect, that they have aged out of a condition they still have.

Adult tics usually take one of three forms: tics that have persisted since childhood, tics that re-emerge in adulthood after years of quiet, and, least commonly, tics appearing for the first time in adult life. Most adults with tics describe a premonitory urge, a rising sensation of tension that the tic briefly relieves. Tics can be suppressed for a time at real cognitive cost, which is why a patient may look nearly tic-free in a meeting and then release a flurry of tics alone in the car. Stress, fatigue, illness, and excitement reliably make tics worse; absorbed concentration often quiets them.

Obsessive-compulsive symptoms, ADHD, anxiety, and depression commonly co-occur with tic disorders, and in many adults the comorbid condition causes more day-to-day impairment than the tics themselves. The boundary with OCD deserves particular care: complex tics and compulsions can look nearly identical, and tic-related OCD responds differently to treatment than OCD without tics.

Genuinely new tics in adulthood warrant a careful diagnostic workup. The differential includes medication-induced movement disorders, other neurological conditions, and functional tic-like behaviors, a distinct presentation that can emerge rapidly in adulthood and responds to different treatment. When the picture suggests a functional tic, the diagnosis itself belongs to a neurologist, and we coordinate that referral; much of the treatment that follows is psychiatric, and our functional neurological disorder program provides it.

Comprehensive Behavioral Intervention for Tics (CBIT), built around habit reversal training, is the first-line treatment for most patients with bothersome tics. It teaches awareness of premonitory urges and trains competing responses, and it has been validated in adults. We help patients access CBIT and coordinate with behavioral therapists who provide it.

When tics are painful, socially costly, or occupationally impairing, medication has a real role. Alpha-2 agonists such as guanfacine and clonidine are often the starting point, particularly when ADHD co-occurs. Dopamine-modulating medications can be meaningfully effective for more severe tics and are weighed carefully against their side-effect profiles. For certain focal tics, we coordinate referral for interventional options such as botulinum toxin. And because many adults arrive on regimens started years ago for tics that have since changed or quieted, we bring a deprescribing lens: the right dose of a medication for a condition that has evolved may be a lower one, or none.

Treating the conditions around the tics is often where patients gain the most. ADHD in a patient with tics can usually still be treated with stimulants, prescribed carefully and monitored. OCD with tics has its own treatment logic. We manage all of it in one place.

Adults with tics get passed back and forth. The psychiatrist calls it a movement disorder and refers out to neurology; the neurologist quiets the movements and refers the OCD and ADHD back to psychiatry. We meet patients who have been making that round trip for years while the condition doing the most damage to their life goes unmanaged.

Neuropsychiatry exists for exactly this kind of condition. Dr. Lodhi and Dr. Patel both trained in the evaluation and treatment of tic disorders during their neuropsychiatry fellowships at Stanford, and tics in adults are core neuropsychiatric territory: one physician managing the movements, the comorbidities, and the interactions between the medications that treat them.
