Infantile Convulsions And Choreoathetosis
Disease Details
Family Health Simplified
- Description
- Infantile convulsions and choreoathetosis (ICCA) is a genetic disorder characterized by the onset of seizures in infancy followed by involuntary, irregular movements typically developing in later childhood.
- Type
- Infantile convulsions and choreoathetosis (ICCA) is a genetic disorder. The type of genetic transmission for ICCA is autosomal dominant.
- Signs And Symptoms
-
Infantile convulsions and choreoathetosis (ICCA) syndrome is a rare genetic disorder characterized by the following signs and symptoms:
1. **Infantile Convulsions**: These are seizures that typically begin in the first year of life. They may present as:
- Generalized tonic-clonic seizures (involving the whole body).
- Focal seizures (affecting one part of the body).
2. **Choreoathetosis**: This refers to the presence of both chorea and athetosis:
- **Chorea**: Rapid, involuntary, and irregular movements.
- **Athetosis**: Slow, writhing movements, often affecting the hands and feet.
In ICCA syndrome, the infantile convulsions usually remit by the age of 2 or 3, but the choreoathetosis can persist and may fluctuate in severity throughout life. - Prognosis
- Infantile convulsions and choreoathetosis (ICCA syndrome) is a rare genetic disorder. Prognosis for individuals with ICCA can vary but is generally considered favorable as seizures typically decrease in frequency with age and often remit by late childhood or adolescence. Choreoathetosis symptoms may also improve over time. However, close medical follow-up is essential to manage symptoms and monitor developmental progress.
- Onset
- For Infantile Convulsions and Choreoathetosis (ICCA) syndrome, the onset typically occurs in infancy or early childhood.
- Prevalence
- The prevalence of infantile convulsions and choreoathetosis is not well documented. It is considered a rare neurological disorder, and precise data on its prevalence are currently unavailable. If you suspect this condition, consulting a medical professional for evaluation and diagnosis is important.
- Epidemiology
- Infantile convulsions and choreoathetosis (ICCA) is a rare genetic disorder. Its exact prevalence is not well-defined due to the rarity and potential underdiagnosis of the condition. ICCA is primarily reported in families of Japanese and Chinese descent, suggesting a higher incidence in these populations. The disorder typically exhibits autosomal dominant inheritance with incomplete penetrance.
- Intractability
- Infantile convulsions and choreoathetosis (ICCA) syndrome often involves episodes of seizures and abnormal involuntary movements. While the condition can be challenging to manage, it is not necessarily intractable. Many individuals respond well to anti-seizure medications and other therapeutic interventions. However, the prognosis can vary widely depending on the specific characteristics of the syndrome in each patient.
- Disease Severity
- Infantile Convulsions and Choreoathetosis (ICCA) is generally considered to be a benign condition. The disease severity is typically mild to moderate, with most affected individuals experiencing manageable symptoms through appropriate medical treatment. The condition is characterized by episodes of convulsions and choreoathetosis that usually improve with age.
- Pathophysiology
- Infantile convulsions and choreoathetosis (ICCA) is a rare genetic disorder. Pathophysiologically, it is primarily associated with mutations in the PRRT2 gene. The PRRT2 gene is involved in the regulation of neuronal excitability and synaptic function. Mutations in this gene lead to abnormal neuronal activity, which manifests as convulsions (seizures) often occurring in infancy, and later, in childhood or adolescence, as choreoathetosis, which includes involuntary, irregular movements. The exact mechanisms by which PRRT2 mutations disrupt neuronal activity are still being researched, but they are thought to affect neurotransmitter release and synaptic transmission. This disorder is inherited in an autosomal dominant pattern.
- Carrier Status
-
Infantile convulsions and choreoathetosis (ICCA) syndrome is a rare genetic disorder. ICCA is often linked to mutations in the PRRT2 gene.
For carrier status:
- Carrier status typically refers to individuals who have one copy of a mutated gene but do not display symptoms of the disorder. Carriers can, however, pass the mutated gene to their offspring.
- ICCA typically follows an autosomal dominant inheritance pattern. This means that having just one copy of the mutated gene can cause the disorder.
- Therefore, the concept of being a "carrier" is not generally applicable in the traditional sense. If an individual has the mutation, they are usually affected by the disorder.

-
Infantile convulsions and choreoathetosis (ICCA) syndrome is primarily characterized by the occurrence of benign infantile seizures and paroxysmal choreoathetosis (a type of involuntary movement disorder).
**Mechanism:**
The exact mechanisms underlying ICCA are not fully understood, but it often follows an autosomal dominant inheritance pattern. The condition manifests early in infancy with seizures and evolves into movement disorders later in life.
**Molecular Mechanisms:**
Mutations in the proline-rich transmembrane protein 2 (PRRT2) gene have been identified in many individuals with ICCA syndrome. PRRT2 is involved in synaptic functions and is thought to play a role in the regulation of neurotransmitter release, particularly at synaptic junctions. A malfunction in PRRT2 can disrupt neural communication, leading to the episodic hyperexcitability observed in seizures and abnormal movement patterns.
Additionally, PRRT2 mutations may affect the interaction with other synaptic proteins, which can disrupt the synaptic vesicle cycle and neuronal signaling pathways, thereby contributing to the clinical manifestations of ICCA.
Understanding these mechanisms is essential for developing targeted therapies and improving the management of ICCA syndrome. - Treatment
-
Infantile convulsions and choreoathetosis (ICCA) syndrome treatment primarily focuses on managing symptoms. Treatment typically includes:
1. **Antiepileptic medications:** To control seizures. Common choices may include valproate, carbamazepine, or phenobarbital.
2. **Physical therapy:** To help manage involuntary movements associated with choreoathetosis.
3. **Regular monitoring:** Regular follow-up with a neurologist to adjust treatment as needed.
Specific treatment plans should be tailored to the individual patient's needs and clinical presentation. - Compassionate Use Treatment
-
Compassionate use treatment for infantile convulsions and choreoathetosis (ICCA) may involve off-label or experimental therapeutics when standard treatments are ineffective or unavailable. Potential treatments can include:
1. **Antiepileptic Drugs (AEDs)**: Off-label use of AEDs like topiramate, levetiracetam, or zonisamide might be considered.
2. **Genetic Therapies**: For cases linked to genetic mutations, experimental gene therapies or precision medicine approaches may be used.
3. **Cannabidiol (CBD)**: Emerging evidence supports its use in refractory epilepsies, though it's experimental for ICCA and requires careful medical supervision.
4. **Ketogenic Diet**: High-fat, low-carbohydrate diets have shown benefits in various epileptic conditions and might be tried on an experimental basis for ICCA.
5. **Deep Brain Stimulation (DBS)**: Although generally used for movement disorders, DBS in experimental settings could be considered for severe cases unresponsive to other treatments.
Each case should be managed individually, and these treatments should only be pursued under the guidance of a specialist and within a framework ensuring patient safety and informed consent. - Lifestyle Recommendations
-
For infantile convulsions and choreoathetosis (ICCA), lifestyle recommendations aim to support overall well-being and manage symptoms. Here are some general suggestions:
1. **Regular Medical Follow-Up:** Ensure consistent appointments with pediatric neurologists to monitor the condition.
2. **Medication Adherence:** Follow prescribed treatments and medications rigorously.
3. **Balanced Diet:** Provide a nutritious diet to support overall health and brain function.
4. **Adequate Sleep:** Ensure the child gets sufficient rest, as sleep can influence neurological health.
5. **Safe Environment:** Create a safe home environment to prevent injury during seizures or involuntary movements.
6. **Physical Therapy:** Engage in physical therapy to improve motor skills and manage choreoathetosis.
7. **Stress Reduction:** Minimize stress as it may exacerbate symptoms.
8. **Education:** Educate family members and caregivers about the condition for better support.
9. **Support Groups:** Consider joining support groups for emotional and practical guidance. - Medication
- Infantile Convulsions and Choreoathetosis (ICCA syndrome) is a rare genetic disorder characterized by the occurrence of benign familial infantile seizures and paroxysmal kinesigenic dyskinesia. Currently, no specific medication is indicated as a cure. Treatment focuses on managing symptoms. Antiepileptic drugs (AEDs) like carbamazepine, oxcarbazepine, or valproate are often used to control seizures. For managing choreoathetosis, options such as anticonvulsants or medications like tetrabenazine, which help reduce involuntary movements, might be considered. Consultation with a neurologist is essential for individualized treatment plans.
- Repurposable Drugs
- There are currently no established repurposable drugs specifically indicated for infantile convulsions and choreoathetosis (ICCA). ICCA is a rare genetic disorder and treatment options typically focus on managing symptoms rather than curing the underlying condition. Standard treatments may include anti-epileptic drugs (AEDs) to control convulsions. Consulting with a specialist for the most appropriate management plan is essential.

-
There is limited specific information on the use of nutraceuticals for infantile convulsions and choreoathetosis. Nutraceuticals typically refer to products derived from food sources that offer extra health benefits. In general, a balanced diet including essential nutrients like vitamins (e.g., vitamin B6), minerals (e.g., magnesium), and omega-3 fatty acids may support overall neurological health. However, any supplementation should be discussed with a healthcare provider to ensure safety and appropriateness for the specific condition.
Nanotechnology-based interventions (nanomedicine) are still mostly in research phases for these conditions. The potential use of nanoparticles could involve targeted drug delivery systems to enhance the effectiveness of medications, reduce side effects, and cross biological barriers like the blood-brain barrier more efficiently. Currently, these applications are not widely available as standard treatments and are subject to ongoing research and clinical trials. - Peptides
