My daughter is 12 years old.
Last summer, her right leg started to shake involuntarily.
The duration varies; sometimes it stops after 5 minutes, and other times it can last for 25 hours.
All physical examinations have come back normal.
Could this be Tourette syndrome?

Dr. Chen Shunsheng reply Rare Disease
The following conditions can cause tremors in the hands and feet: 1.
Tourette syndrome 2.
Focal motor epilepsy 3.
Peripheral nerve dysfunction: Often seen in various early peripheral neuropathies, commonly accompanied by muscle cramps or twitching symptoms 4.
Essential tremor: A familial tremor of unknown origin, rare in children 5.
Parkinson's disease: Caused by degeneration of the substantia nigra leading to dopamine deficiency, typically starting with limb tremors, common in the elderly 6.
Other basal ganglia disorders: Requires diagnosis by a neurologist 7.
Certain metabolic diseases: Such as liver disease, kidney disease, etc., requiring medical diagnosis 8.
Insufficient energy supply to muscles: Such as hunger, hypoglycemia, energy deficiency myopathy, etc.
9.
Increased cardiac output: Such as in hyperthyroidism or other conditions, where significant blood ejection from the heart can cause muscle contractions and tremors 10.
Certain medications can induce tremors 11.
Anxiety and stress: Resulting from muscle tension and contractions.

More Info
Tourette Syndrome (TS) is a neurological disorder characterized by repetitive, involuntary movements and vocalizations called tics. It typically manifests in childhood, with symptoms often appearing between the ages of 5 and 10. The tics can be motor (such as blinking, head jerking, or shoulder shrugging) or vocal (such as throat clearing, grunting, or repeating words). While the exact cause of Tourette Syndrome is not fully understood, it is believed to involve a combination of genetic and environmental factors.
In your daughter's case, the involuntary shaking of her right leg could potentially be a tic, especially if it occurs in bursts and varies in duration. However, it is essential to consider that not all involuntary movements are indicative of Tourette Syndrome. Other conditions, such as myoclonus (sudden muscle jerks), essential tremors, or even anxiety-related movements, could also explain her symptoms. A thorough evaluation by a healthcare professional, preferably a neurologist or a psychiatrist specializing in movement disorders, is crucial for an accurate diagnosis.
Regarding the hereditary aspect of Tourette Syndrome, there is evidence suggesting a genetic component. Studies have shown that TS can run in families, and individuals with a family history of TS or other tic disorders are at a higher risk of developing the condition. However, the inheritance pattern is complex and not strictly Mendelian, meaning that multiple genes and environmental factors likely contribute to the risk.
It's also important to note that while TS is a lifelong condition, many individuals experience a reduction in symptoms as they reach adulthood. Treatment options vary depending on the severity of the tics and their impact on daily life. Behavioral therapies, such as Comprehensive Behavioral Intervention for Tics (CBIT), and medications may be recommended if the tics are causing significant distress or impairment.
In your daughter's situation, since she is only 12 years old and has been experiencing these symptoms for a relatively short time, it would be beneficial to monitor her condition closely. Keeping a diary of her tics, noting their frequency, duration, and any potential triggers, can provide valuable information for her healthcare provider.
Additionally, you mentioned that your daughter is reluctant to discuss her condition. This is not uncommon among adolescents, who may feel embarrassed or anxious about their symptoms. Encouraging open communication and providing a supportive environment can help her feel more comfortable sharing her experiences when she is ready.
In summary, while your daughter's symptoms could potentially align with Tourette Syndrome, a comprehensive evaluation by a medical professional is necessary for an accurate diagnosis. Understanding the nature of her movements, their frequency, and any associated factors will be crucial in determining the appropriate course of action. If TS is diagnosed, there are effective management strategies available to help her cope with the condition and lead a fulfilling life.
