A neurological disorder called Tourette syndrome causes repetitive and involuntary movements or sounds. Tics can affect any part of the body, including the face, eyes, head, shoulders, arms, legs, or vocal cords. The severity, frequency, and type of tics can vary. A person with Tourette syndrome may also suffer from attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, depression, or learning difficulties.
Tourette syndrome is not known to have an exact cause, but it is believed to be influenced by genetic, developmental, and environmental factors. A problem in the brain's communication system, such as dopamine and serotonin, may cause Tourette syndrome. Nerve cells communicate with each other through these chemicals, which control their movements, emotions, and behaviors. People with Tourette syndrome are more likely to develop the condition if they have a close relative who suffers from it. Some environmental factors, such as infections, stress, trauma, or drugs, may trigger or worsen tics in some people, even if they inherit the genes for Tourette syndrome.
The main symptom of Tourette syndrome is having tics, which are involuntary and uncontrollable movements or sounds. Tics can be classified as:
Simple tics: These involve a limited number of muscles or sounds, such as blinking, sniffing, grunting, or shrugging.
Complex tics: These involve more coordinated and elaborate movements or sounds, such as touching objects, repeating words or phrases, making gestures, or saying inappropriate or offensive things.
Boys are more likely to suffer from tics between the ages of 2 and 15, and the type, location, frequency, and severity of tics may change over time. Occasionally, people may experience periods when tics increase or decrease, or even periods when they are tic-free. While some people may be able to suppress their tics for a short period of time, they may also feel an urge to perform the tic, which relieves them of their tension or urge. In addition to stress, anxiety, excitement, fatigue, or illness, tics may also be influenced by external factors, such as temperature, light, sound, or medication. Tics may also occur during sleep, but they are usually less frequent and less intense.
There is no specific test for Tourette syndrome. The diagnosis is based on the history and symptoms of the person. To be diagnosed with Tourette syndrome, a person must have:
Both motor and vocal tics
Tics that occur many times a day, nearly every day, or intermittently, for more than a year
Tics that start before the age of 18
No other medical condition or substance that can explain the tics
The doctor may also ask about the family history, the onset and course of the tics, whether they interfere with the person's daily life, and if any other conditions are present, such as ADHD, OCD, anxiety, or depression. In addition to performing a physical examination, a doctor may order some tests to rule out other possible causes of the symptoms, including blood tests, urine tests, and brain imaging.
There is no cure for Tourette syndrome, but there are treatments that can help reduce the severity and frequency of the tics, and improve the quality of life of the person. The treatment options include:
A variety of drugs can be used to control tics by affecting neurotransmitter levels in the brain. These include antipsychotics, stimulants, alpha-2 adrenergic agonists, antidepressants, and antianxiety medications. However, these drugs may cause side effects, such as weight gain, sedation, mood changes, or movement problems. Consequently, the doctor prescribes the lowest effective dose and monitors the patient's response and tolerance.
The goal of behavioral therapy is to manage the tics and premonitory urges by learning habit reversal, exposure and response prevention, or relaxation techniques. A person can use these techniques to become more aware of their tics, replace them with less noticeable or harmful behaviors, or cope with stress or anxiety that may trigger or worsen them.
Talking to a therapist can help with emotional and social issues related to Tourette syndrome, such as low self-esteem, depression, anxiety, anger, or isolation. Through psychotherapy, a person can understand and accept their condition, cope with the challenges and stigma associated with it, and improve their relationships and functioning as a whole.
Education and support: This involves learning more about Tourette syndrome, its causes, symptoms, and treatments, as well as how to deal with it in different situations, such as school, work, or social settings. In addition to education and support, individuals can join a support group to share their experiences and feelings with others with Tourette syndrome, and receive help and encouragement from others.
There is no known way to prevent Tourette syndrome, as it is largely determined by genetic factors. However, some steps that may help reduce the risk or severity of the tics include:
Avoiding or minimizing exposure to environmental triggers, such as infections, stress, trauma, or drugs
Maintaining a healthy lifestyle, such as eating a balanced diet, getting enough sleep, exercising regularly, and avoiding alcohol and tobacco
Seeking early diagnosis and treatment, as this may help prevent or delay the onset of more severe or complex tics, and reduce the impact of the condition on the person’s life
Seeking professional help and support, as this may help the person cope with the emotional and social challenges of having Tourette syndrome, and improve their self-esteem and well-being
