Presentation
Genetic counseling ICCA syndrome can present as sporadic or familial; in the latter case, it is transmitted as an autosomal dominant trait that can be variably expressed within the same family. [orpha.net]
Since the first report similar clinical presentations have been published which confirm the specificity of the ICCA syndrome. [en.wikipedia.org]
On the opposite side of the spectrum, the group of benign epilepsy syndromes presented in this book is clearly more prevalent in childhood than the intractable epilepsies. [books.google.com]
At age of9 years, he presented episodes with pallor, sweating,and proximal, irregular, not-stereotyped and arrhythmicinvoluntary movements resembling ballism, followed bychoreiform movements and dystonic postures of thetrunk. [docslide.com.br]

Infantile convulsions and choreoathetosis (ICCA) syndrome is a neurological genetic disorder with an autosomal dominant mode of inheritance. [en.wikipedia.org]
- Seizure
Typical seizures are brief with motor arrest, deviation of the head and eyes to one side, generalised hypertonia, cyanosis, and limb jerks. Seizures are focal with or without secondary generalisation and usually occur in clusters. [doi.org]
Some individuals may experience both PKD and seizures while others exhibit PKD or seizures only. [genedx.com]
Clinical description Benign familial infantile epilepsy begins at 3 to 12 months of age with a family history of the same type of seizures. Seizures are afebrile, partial or sometimes generalized, and normally disappear after the first year of life. [orpha.net]

Clinical features can include dystonia, parkinsonism, gait abnormalities, psychosis, dementia, and chorea. [mendelian.co]
Studies have begun, and in cerebral palsy patients affected with dystonia- choreoathetosis, it has been demonstrated that neurostimulation has been an effective treatment in lessening symptoms in patients. [eng.ichacha.net]
Differential diagnosis Differential diagnosis includes other paroxysmal dystonias such as paroxysmal exertion-induced dyskinesia and paroxysmal non-kinesigenic dyskinesia (see these terms) triggered by drugs or food intake (such as caffeine and alcohol [orpha.net]
They are characterised by episodes of involuntary abnormal movements (dyskinesia) that correspond to attacks of choreoathetosis or dystonia. [doi.org]
- Ataxia
The association with other paroxysmal disorders such as migraine, with or without aura, hemiplegic migraine, episodic ataxia and tics has also been described. Psychomotor development is normal. [orpha.net]

Examples include: mutations of the KCNA1 potassium channel subunit gene in epilepsy with episodic ataxia type 1 39 ; rare mutations within the ATP1A2 sodium/potassium pump subunit gene in familial hemiplegic migraine, associated or not with infantile [doi.org]
Episodic ataxias Episodic ataxias are rare autosomal dominant disorders divided into two major categories: episodic ataxia type 1 (EA1) and 2 (EA2) both of which are channelopathies in which a movement disorder and epilepsy may co-exist. [epilepsydiagnosis.org]

Treatment

Treatment with anticonvulsants is usually effective in controlling the attacks. BFIS results in generalized tonic-clonic and complex partial seizures that typically occur in clusters between 3-24 months of age. [genedx.com]

Prognosis
Prognosis ICCA has a good outcome. Without treatment, dyskinetic attacks tend to disappear during adulthood. The documents contained in this web site are presented for information purposes only. [orpha.net]
Neurologists and paediatricians should be familiar with these conditions because accurate diagnosis, and its consequent good prognosis, may save much suffering to the family. [books.google.com]

Accurate diagnosis is very important as it is amenable to low-dose anticonvulsant treatment and in general of good prognosis. In agreement with other studies, our family may not be related to SLC5A11 gene mutation. [ashg.org]
Etiology
Etiology The genetic loci of ICCA syndrome have been described on chromosomes 16p11.2-q12.1, 16q13-q22.1 and 3q29-29. [orpha.net]
Considering our findings and those reported in literature, 23 PRRT2 mutations explain similar to 56% of the families analyzed.Conclusions: PRRT2 mutations are the major cause of PKD or ICCA, but they do not seem to be involved in the etiology of febrile [rug.nl]

Common clinical features, epidemiological studies, shared therapeutic strategies, and familial co-inheritance all argue in favour of close relationships between various epileptic syndromes and other paroxysmal disorders of the brain, 35 such as migraine [doi.org]
Pathophysiology
The pathophysiology of PD remains largely unknown. [doi.org]
Alterations of ion channel and ion pump subunits could provide a simple, albeit probably non-unique, explanation for the pathophysiology of the link between epilepsy and PD. [ncbi.nlm.nih.gov]

Evidence for shared pathophysiologic mechanisms underlying the concurrence of benign infantile convulsions (IC) and of PKD in the same patients or families was obtained [ 8, 13 ]. [mdpi.com]
It is considered a migraine variant as there is often a family history of migraine headache, though the pathophysiology is not well understood. Usually no trigger to a particular episode can be defined. [epilepsydiagnosis.org]
Prevention
The retained awareness and history of triggers should prevent misdiagnosis as focal seizures. [epilepsydiagnosis.org]
