Introduction:
Many people, at some point in their life, experience spasm-like movements of certain muscles. These types of movements, called tics and twitches, often affect the eyelids or face. They can, however, occur anywhere in the body. In most cases, tics and twitches are harmless and temporary. In some cases, though, they may be caused due to a tic disorder. Tic disorders can generally be managed with treatment and lifestyle changes.
What Is Chronic Motor Tic Disorder?
A chronic motor tic disorder is a condition that involves small, uncontrolled, spasm-like movements or vocal outbursts (referred to as phonic tics), but not both. If an individual experiences both a physical tic and a vocal outburst, the condition is known as Tourette syndrome.
A chronic motor tic disorder is much more common than Tourette syndrome but less common than transient tic disorder. A chronic motor tic disorder is a temporary and self-limited disorder expressed in the form of tics. Another type is called dystonic tics, which presents as abrupt bursts of movement later followed by a sustained contraction.
Chronic motor tic disorder starts appearing before 18 years of age and usually resolves within four to six years. Treatment can help reduce the effect of this condition on school or work life.
What Causes Chronic Motor Tic Disorder?
Doctors are not completely sure what leads to chronic motor tic disorder or why some kids develop it before others. Some suggest chronic motor tic disorder may be caused due to the result of physical or chemical abnormalities in the brain.
The chemicals that carry signals throughout the brain are called neurotransmitters. Sometimes they may not be working properly or not communicating correctly. This results in the same message being sent over and over again. It causes a physical tic.
Who Has a Risk of Chronic Motor Tic Disorder?
Children who have a family history of chronic tics or twitches are more predisposed to develop chronic motor tic disorder. In addition, boys are at higher risk of having chronic motor tic disorder than girls.
What Are the Symptoms of Chronic Motor Tic Disorder?
Individuals with a chronic motor tic disorder may exhibit the following symptoms:
-
Grimacing of the face (frowned appearance on the face).
-
Involuntary uncontrollable eye and face movements, such as repeatedly blinking, twitching of the nose, or jerking or clenching of the jaw.
-
Involuntary jerking of the arms, legs, or body muscles, but rarely the torso.
-
Producing certain sounds that can include grunts, coughs, sniffling, throat clearing, and contractions of the abdomen and diaphragm.
Some individuals experience strange sensations in the body before a tic occurs. They are usually capable of restraining their symptoms for short periods, but this requires effort. Giving in to a tic allows a sense of relief. They describe it as a response to an inner urge.
Tics may get worse due to:
-
Distress, anxiety, or embarrassment.
-
Lack of proper sleep.
-
Intense emotions.
-
Fever or illness.
-
Heat.
-
Excitement.
How to Diagnose Chronic Motor Tic Disorders?
Tics are generally diagnosed during a regular appointment at a doctor’s office. Out of the following listed requirements, you or your child must meet two of the requirements to receive a diagnosis of chronic motor tic disorder:
-
Having an age less than 18 years when the tics began appearing.
-
Show one or more motor tics.
-
Have tics that often occur throughout the day, every single day, or occasionally sometimes as on and off for a minimum of a year.
-
Have not been diagnosed with Tourette syndrome.
-
Have tics that do not occur as a result of taking certain medications or other drugs and are not caused due to other medical issues.
Chronic motor tics are diagnosed only by physical examination, and no tests are generally needed.
How Is Chronic Motor Tic Disorder Treated?
The treatment that a person receives for chronic motor tic disorder will depend mainly on the severity of the disorder and how it is affecting their life. Medications and talk therapy (behavioral therapy) are the treatment options when the tics have a significant effect on the daily activities of the child or an adult.
Cognitive Behavioral Therapy
Cognitive behavioral therapy can prove helpful for a child to learn to restrain or control a tic for a short period of time. According to a study that was published in the journal of the American Medical Association in 2010, a treatment approach known as a comprehensive behavioral intervention for tics (CBIT) significantly improved symptoms of chronic motor tics in children.
In CBIT, children with chronic motor tics are trained and educated to recognize the urge of a tic and the use of a competing or replacement response instead of the tic.
Medications
Certain medications can help to control or reduce the tics. Medicines that doctors sometimes prescribe to control tics include the following:
-
Haloperidol (Haldol).
-
Risperidone (Risperdal).
-
Pimozide.
-
Topiramate (Topamax).
-
Aripiprazole (Abilify).
-
Guanfacine.
-
Clonidine.
-
Cannabis-based medications.
Cannabis-based products must not be given to children, adolescents, or pregnant, or lactating mothers. Other medical treatments may include a surgical procedure that involves the implantation of an electrical device in the brain. In addition, some individuals may get relief from the implantation of electrodes in the brain.
What Can Be Expected as the Long-Term Outlook (Prognosis) Of Chronic Motor Tic Disorder?
Those children who develop chronic motor tic disorder between six and eight years of age often do very well. However, symptoms of this disorder may last for four to six years and then stop showing in the early teens without the need for any treatment. When the condition starts in older children and gets carried on into the 20s, then it may turn into a lifelong condition.
Conclusion:
A chronic motor tic disorder is a condition characterized by small, fast, uncontrollable muscle movements that can occur anywhere in the body but most commonly affects the eyelids, face, arms, and legs. These movements are spasm-like and are brief and temporary. It usually affects young children but sometimes may also occur in adults. Medications and behavioral therapy are the recommended treatment of choice for this disorder.
