Some research suggests that tics are more common among children with learning disabilities and are seen more in special education classrooms. Children within the autism spectrum are also more likely to have tics. Tics that appear before the age of 18 and last for 1 year or more may be classified as a chronic tic disorder. These tics can be either motor or vocal, but not both. Chronic tic disorder is less common than transient tic disorder, with less than 1 percent of children affected. If the child is younger at the onset of a chronic motor or vocal tic disorder, they have a greater chance of recovery, with tics usually disappearing within 6 years.
People who continue to experience symptoms beyond age 18 are less likely to see their symptoms resolved. It is characterized by multiple tics — both motor and vocal. It is the most severe and least common tic disorder. CDC research suggests that half of all children with the condition are not diagnosed. Currently, 0. The defining symptom of tic disorders is the presence of one or more tics.
These tics can be classified as:. Tics are usually preceded by an uncomfortable urge, such as an itch or tingle. While it is possible to hold back from carrying out the tic, this requires a great deal of effort and often causes tension and stress. Relief from these sensations is experienced upon carrying out the tic. The exact cause of tic disorders is unknown. Brain chemistry also seems to be important, especially the brain chemicals glutamate, serotonin , and dopamine. Tics that have a direct cause fit into a different category of diagnosis.
These include tics due to:. Other complications associated with tic disorders are related to the effect of the tics on self-esteem and self-image. Some research has found that children with TS or any chronic tic disorder experience a lower quality of life and lower self-esteem than those without one of these conditions.
In addition, the Tourette Association of America say that people with TS often experience difficulties with social functioning due to their tics and associated conditions, such as ADHD or anxiety. Tic disorders are diagnosed based on signs and symptoms.
The child must be under 18 at the onset of symptoms for a tic disorder to be diagnosed. Also, the symptoms must not be caused by other medical conditions or drugs. Some kids, Dr. Nash says, may be practicing a version of this when they try to turn attention-drawing tics into something that seems more natural — for example, turning a grimace into a yawn, or a hand flip into what looks like a stretch.
As part of HRT children may also be taught relaxation techniques like breathing or mindfulness exercises that can help decrease the frequency of their tics. Medication options for tics and tic disorders vary widely, depending on the severity of the tics and other disorders a child may have. Some medications for other disorders, such as ADHD, are suspected of triggering or exacerbating tics.
But, says Dr. Nash, the evidence is unclear as to whether medications can either improve or worsen tics because of their cyclical nature. The same is true for habit reversal therapy, Dr. Nash explains. Get this as a PDF. Enter email to download and get news and resources in your inbox. Share this on social.

Movements may include eye blinking, shoulder shrugging, neck twisting, facial grimacing, sticking out tongue, flaring nostrils, clenching fists, jerking arms, kicking, and curling toes. Tics can also be vocal. These vocal tics may include throat-clearing, sniffing or snorting, grunting, dry coughs, clicking, hissing, barking, or even words or phrases.
They tend to increase under excitement, physical or social stress, anxiety, or if the individual is very tired. Some medications are also believed to exacerbate tics. Tics do not occur during sleep. Treatment for an individual with a tic disorder may include medication to help control the symptoms. Clonidine and guanfacine, types of anti-hypertensive agents, may also be used for mild to moderate tics and may be better tolerated than the neuroleptics.
The most common tic disorder is called provisional tic disorder PTD , which was previously known as transient tic disorder, which is common in children. Approximately one in five children age years old may develop a tic, but may sometimes start as early as two years of age.
Chronic tic disorders affect about one percent of children and may indicate a more serious disorder called Tourette Syndrome TS. Tourette syndrome is a genetic, neurological disorder whose primary manifestations are the presence of motor and vocal tics. Tourettes is commonly associated with ADHD, obsessive-compulsive disorder, behavior problems, and learning disabilities.
The National Institute of Neurological Disorders and Stroke report that approximately , Americans have the most severe form of Tourettes, while as many as one in display Tourette syndrome and other chronic tic disorders.
Though Tourettes is a lifelong condition, symptoms tend to peak during the early teenage years with improvement in later adolescence and adulthood. Tourettes affects males approximately three to four times more often than females. There has been some controversy over whether stimulants, the most common form of medication therapy for ADHD , worsen or even cause tics.
Studies indicate that most children with co-occurring tics and ADHD do not experience an increase in tic severity while on low to moderate doses of stimulants. However, there does appear to be a small proportion of children for whom this is a problem.
