Paroxysmal dystonic choreoathetosis (PDC) is an unusual hyperkinetic movement disorder characterized by attacks of chorea, dystonia, and ballism with onset in childhood. We report a large British family with dominantly inherited PDC linked to chromosome 2q and describe the clinical features in 20 affected family members. Attacks were precipitated by a variety of factors, including caffeine, alcohol, or emotion, and could be relieved by short periods of sleep in most subjects. The clinical features in the family are compared with those of 11 other PDC families in the literature and a core phenotype for PDC suggested. CSF monoamine metabolites measured at baseline and during an attack in one subject were found to increase during the attack. Magnetic resonance spectroscopy of brain and basal ganglia performed both during and between attacks was normal. Positron emission tomography using the D2 receptor ligand, 11C-raclopride, showed no abnormalities. 相似文献

The paroxysmal dyskinesias 总被引:17,自引:0,他引:17

The clinical, pathophysiological and genetic features of some of the paroxysmal movement disorders are reviewed. Paroxysmal
kinesigenic choreoathetosis/dyskinesias (PKC/PKD) is a condition in which brief and frequent dyskinetic attacks are provoked
by sudden movement. PKC is more common in men and can be idiopathic (commonly familial) or due to a variety of causes. The
pathophysiology of PKC is uncertain but it could be an ion-channel disorder. Antiepileptic drugs particularly carbamazepine
are very helpful in a large proportion of cases. Paroxysmal exercise induced dystonia (PED) is a rare disorder manifesting
as episodes of dystonia mostly affecting the feet induced by continuous exercise like walking or running. Although the initial
cases were familial, there is a higher proportion of sporadic cases. The pathophysiology of PED is unknown and antiepileptic
drugs are generally unhelpful. In paroxysmal dystonic choreoathetosis/ non-kinesigenic dyskinesias (PDC/ PNKD) the attacks
are of long duration and induced by variety of factors including coffee, tea, alcohol and fatigue but not by sudden movement.
PDC can be idiopathic (familial or sporadic) or symptomatic due to a variety of causes. The gene for familial PDC has been
linked in 2 families to chromosome 2 q close to a cluster of ion channel genes again suggesting that this disorder may also
be a channelopathy. Other paroxysmal disorders include paroxysmal nocturnal dyskinesia, a form of frontal lobe epilepsy in
some cases which may be familial with autosomal dominant inheritance (ADNFLE). The gene for ADNFLE in one family has been
found to be a mutation in the neuronal acetylcholine receptor gene (CHRNA4) on chromosome 20q. Tonic spasms in multiple sclerosis and Sandiffers syndrome producing intermittent torticollis in infants
and children are other paroxysmal movement disorders.

The clinical, pathophysiological and genetic features of some of the familial (idiopathic) paroxysmal movement disorders are reviewed. The paroxysmal dyskinesias share features and therefore may have the same pathophysiological mechanisms as other episodic neurological disorders which are known to be channelopathies. Paroxysmal kinesigenic choreoathetosis/dyskinesias (PKC/PKD) is a condition in which brief and frequent dyskinetic attacks are provoked by sudden movement. Antiepileptics particularly carbamazepine are very helpful for this condition. PKC has similarities to episodic ataxia type 1 which is caused by mutations of the KCNA1 gene. PKC and a related disorder in which infantile convulsions are associated (ICCA syndrome) have recently been linked to the pericentromic region of chromososme 16 in the vicinity of some ion channel genes. Paroxysmal exercise-induced dystonia (PED) is a rare disorder manifesting as episodes of dystonia mostly affecting the feet induced by continuous exercise like walking or running. The pathophysiology of PED is unknown and antiepileptic drugs are generally unhelpful. In paroxysmal dystonic choreoathetosis/nonkinesigenic dyskinesias (PDC/PNKD) the attacks are of long duration and induced by a variety of factors including coffee, tea, alcohol and fatigue but not by sudden movement. The gene for familial PDC has been linked to chromosome 2q close to a cluster of ion channel genes. Paroxysmal nocturnal dyskinesia is now known to be a form of frontal lobe epilepsy in some cases which may be familial with an autosomal dominant inheritance and has been given the eponym ADNFLE. ADNFLE is a genetically heterogenous condition. Mutations of the neuronal nicotinic acetylcholine receptor gene that have chromosome 20q have been reported in some families with ADNFLE. However, another family with ADNFLE has been linked to chromosome 15 in the area of another nicotinic acetylcholine receptor gene. Thus the familial paroxysmal dyskinesias appear to be clinically and genetically heterogeneous. 相似文献

(+)-alpha-[11C]Dihydrotetrabenazine PET imaging in familial paroxysmal dystonic choreoathetosis 总被引:1,自引:0,他引:1
Clinical observations suggest a disturbance of striatal dopaminergic function in familial paroxysmal dystonic choreoathetosis (PDC). The authors used PET with [11C]dihydrotetrabenazine (DTBZ) to study striatal dopaminergic innervation in PDC. The results did not reveal abnormal DTBZ binding potential in PDC striatum. This suggests that dopaminergic abnormalities, if present, may be due to altered regulation of dopamine release or to postsynaptic mechanisms, rather than to an altered density of nigrostriatal innervation. 相似文献

Familial paroxysmal dystonic choreoathetosis: clinical findings in a large Japanese family and genetic linkage to 2q. 总被引:6,自引:0,他引:6

BACKGROUND: Paroxysmal dystonic choreoathetosis (PDC) is a rare familial movement disorder that has been mapped to chromosome 2q31-36. OBJECTIVE: To study the first Japanese family with PDC clinically and genetically. PATIENTS AND METHODS: We studied a large Japanese family in which at least 17 members in 6 generations have been affected by PDC. We interviewed and examined 26 family members, 8 of whom revealed choreoathetosis-like and dystonialike involuntary movement and 1 of whom revealed no involuntary movement but only muscle stiffness such as the aura of paroxysmal dystonic choreoathetosis (PDC). Genetic linkage studies of this family were carried out with polymorphic DNA markers. RESULTS: The attacks of involuntary movement or muscle stiffness were precipitated by ovulation, menstruation, emotional stress, or caffeine or alcohol ingestion. Magnetic resonance imaging of the brain revealed no abnormalities. Clonazepam therapy was effective for reducing the attacks, and ingestion of garlic was believed by patients to be effective for softening the attacks. An affected woman with only muscle stiffness showed remission after hysterectomy for hysteromyoma. This woman also had the disease haplotype and transferred it to her typical PDC-affected daughter. Maximal pairwise logarithm of odds scores exceeding 2.00 were obtained at D2S2250, D2S1242, D2S377, D2S2148, and D2S126. The PDC gene was demonstrated by linkage analyses to be located in a 15.3-centimorgan interval lying between D2S371 and D2S339 based on pairwise and multipoint logarithm of odds scores and obligate recombination events in affected individuals. CONCLUSIONS: Linkage of PDC to chromosome 2q32-36 was confirmed in a Japanese family. The clinical characterizations of this family with PDC include that ovulation seems also to be a precipitating factor of the attacks and that hysterectomy seems to be effective for softening the attacks. Although low-dose clonazepam treatment was most effective, garlic use was believed by affected members to be effective for softening the attacks. Furthermore, based on the results of clinical and genetic analyses, we suggest that muscle stiffness without involuntary movement may represent a forme fruste of PDC. 相似文献

Infantile bilateral striatal necrosis (IBSN) is characterized by a dystonic movement disorder and basal ganglia imaging abnormalities. Acute IBSN often occurs after upper respiratory tract infections although no specific micro-organism which may cause IBSN has been identified. We present 2 children (1 year 2 months and 4 years) with acute IBSN after clinical pharyngitis. Both IBSN patients had serological evidence of recent beta-haemolytic streptococcal infection. Due to the association of post-streptococcal disorders with anti-basal ganglia antibodies (ABGA), we examined both patients for anti-neuronal antibodies. For comparison, 20 children with dystonia (9 females, 11 males; mean age 4 years 1 month), and 20 children with uncomplicated streptococcal infection (12 females, 8 males; mean age 5 years 9 months) were examined. Both IBSN patients had antibodies reactive against basal ganglia constituents of molecular weight 40 kDa. Immunohistochemistry showed antibody reactivity against large striatal neurons only. Other anti-neuronal antibodies were negative, supporting striatal specificity. All controls were negative for ABGA. Acute IBSN is part of the poststreptococcal autoimmune neuropsychiatric spectrum. An autoimmune aetiology should be considered in this phenotype, as immunomodulatory therapies may reduce morbidity and mortality. 相似文献

Poststreptococcal acute disseminated encephalomyelitis with basal ganglia involvement and auto-reactive antibasal ganglia antibodies. 总被引:5,自引:0,他引:5

Antibasal ganglia antibodies (ABGA) are associated with Sydenham's chorea and pediatric autoimmune neuropsychiatric disorders associated with streptococcal infections. We present 10 patients with acute disseminated encephalomyelitis (ADEM) associated with Group A beta hemolytic streptococcal infection. The clinical phenotype was novel, with 50% having a dystonic extrapyramidal movement disorder, and 70% a behavioral syndrome. None of the patients had rheumatic fever or Sydenham's chorea. Enzyme-linked immunosorbent assay, Western immunoblotting, and immunohistochemistry were used to detect ABGA. Neurological (n = 40) and streptococcal (n = 40) controls were used for comparison. Enzyme-linked immunosorbent assay results showed significantly elevated ABGA in the patients with poststreptococcal ADEM. Western immunoblotting demonstrated ABGA reactivity to three dominant protein bands of 60, 67, or 80 kDa; a finding not reproduced in controls. Fluorescent immunohistochemistry demonstrated specific binding to large striatal neurones, which was not seen in controls. Streptococcal serology was also significantly elevated in the poststreptococcal ADEM group compared with neurological controls. Magnetic resonance imaging studies showed hyperintense basal ganglia in 80% of patients with poststreptococcal ADEM, compared to 18% of patients with nonstreptococcal ADEM. These findings support a new subgroup of postinfectious autoimmune inflammatory disorders associated with Group A beta hemolytic streptococcus, abnormal basal ganglia imaging, and elevated ABGA. 相似文献

A family is presented with paroxysmal dystonic choreoathetosis transmitted as a dominant trait over five generations. The family is unusual in the marked responsiveness of the episodes to short periods of sleep in several members, in the very variable age of onset, and in the association with prominent myokymia in some cases. These overlap features suggest a link between paroxysmal dystonic choreoathetosis and familial paroxysmal ataxia with myokymia. 相似文献

PURPOSE OF REVIEW: Autoimmune disease has long been intertwined with investigations of infectious causes. Antibodies that are formed against an infectious agent can, through the process of molecular mimicry, also recognize healthy cells. When this occurs, the immune system erroneously destroys the healthy cells causing autoimmune disease in addition to appropriately destroying the offending infectious agent and attenuating the infectious process. The first infectious agent shown to cause a post-infectious autoimmune disorder in the central nervous system was Streptococcus pyogenes in Sydenham's chorea. The present review summarizes the most recent published findings of central nervous system diseases that have evidence of a post-streptococcal autoimmune etiology. RECENT FINDINGS: Sydenham's chorea and other central nervous system illnesses that are hypothesized to have a post-streptococcal autoimmune etiology appear to arise from targeted dysfunction of the basal ganglia. PANDAS (pediatric autoimmune disorders associated with streptococcal infections) is the acronym applied to a subgroup of children with obsessive-compulsive disorder or tic disorders occurring in association with streptococcal infections. In addition, there are recent reports of dystonia, chorea encephalopathy, and dystonic choreoathetosis occurring as sequelae of streptococcal infection. Investigators have begun to isolate and describe antistreptococcal-antineuronal antibodies as well as possible genetic markers in patients who are susceptible to these illnesses. SUMMARY: Clinical and research findings in both immunology and neuropsychiatry have established the existence of post-streptococcal neuropsychiatric disorders and are beginning to shed light on possible pathobiologic processes. 相似文献

Familial paroxysmal dystonic choreoathetosis and its differentiation from related syndromes 总被引:9,自引:0,他引:9

Four generations of a family are described in which 7 of 8 affected members suffered from prolonged dystonic seizures; the eighth member's attacks were those of paroxysmal choreoathetosis. The attacks lasted up to 4 hours, were precipitated by alcohol, emotion, or fatigue, and responded poorly to phenytoin and barbiturates but were controlled by clonazepam. Autopsy on an affected child who died a "crib death" at the age of 2 years disclosed no major abnormality of the brain. This family appears to have the same condition as that described by Mount and Reback in 1940, Forssman in 1961, and Richards and Barnett in 1968, which the last authors termed paroxysmal dystonic choreoathetosis to distinguish it from the more common movement-induced (kinesigenic) form of the disorder. Analysis of reports of 100 cases of paroxysmal kinesigenic choreoathetosis shows that the attacks last less than 5 minutes, are precipitated by sudden movement or startle, and usually respond well to phenytoin or barbiturates. A clinical classification is presented in which the kinesigenic form is divided into a familial group (72% of cases) and a sporadic group (28% of cases) and contrasted with paroxysmal dystonic choreoathetosis. One family with an intermediate form, in which dystonic choreoathetosis was provoked by continued exertion and lasted for up to 30 minutes, is also reported. 相似文献

Background: Bipolar disorder (BD) has been linked with the manifestation of catatonia in subjects with autism spectrum disorders (ASD). Idiopathic basal ganglia calcification (IBGC) is characterized by movement disorders and various neuropsychiatric disturbances including mood disorder. Case: We present a patient with ASD and IBGC who developed catatonia presenting with prominent dystonic feature caused by comorbid BD, which was treated effectively with quetiapine. Conclusion: In addition to considering the possibility of neurodegenerative disease, careful psychiatric interventions are important to avoid overlooking treatable catatonia associated with BD in cases of ASD presenting with both prominent dystonic features and apparent fluctuation of the mood state. 相似文献

Alternating hemiplegia in childhood (Verret, 1971) is a disorder presenting with frequent episodes of alternating hemiplegia from early infancy. We report a patient with this disorder, along with a pathophysiological study and a discussion about the available therapies for this disorder. The patient, an 11-year-old boy, visited our hospital with episodes of alternating hemiplegia from early infancy. His family history showed that many members suffered from migraine. He was born with asphyxia. Mental and motor developmental delays were seen from early infancy. The hemiplegic episodes with ipsilateral facial palsy had occurred frequently from early infancy. The episodes were frequently induced by emotional stress. The duration of hemiplegia varied from 10 minutes to 3 days. From the age of 11 years, he had begun to have migrainous attacks with or without hemiplegic episodes. Neurological examination revealed slight muscle hypotonia, choreoathetosis and dystonic movements induced by locomotion, positive Myerson sign, increased deep tendon reflexes and Babinski reflex. CAG, VAG and CAT revealed normal findings. EEG revealed diffuse generalized slowing during hemiplegic episodes. Measurement of regional cerebral blood flow (CBF) by 133Xe inhalation method revealed a slight decrease of bilateral CBF during a quadriplegic episode. Positron emission tomography using C15O2 revealed a slight decrease of CBF at the insula, putamen and claustrum of the left side during a right sided episode. Increased excretion of urinary 5-HIAA was seen during one episode. From our clinical and laboratory findings, we think this disorder may be a special type of migraine. Therapeutic trials of diazepam and flunarizine were both effective, but the initial effectiveness was decreased after 5 months. 相似文献

The genetically dystonic hamster is an animal model of idiopathic dystonia that displays sustained abnormal movements and postures either spontaneously or in response to mild environmental stimuli. Previous pharmacological studies have shown that competitive and non-competitive N-methyl-d-aspartate (NMDA) receptor antagonists exert potent antidystonic activity in this model, indicating that abnormal NMDA receptor function may be involved in the pathophysiology of this movement disorder. Autoradiographic analysis of NMDA receptor density in 67 brain regions, using the ligand [3H]N-(1-[2-thienyl]cyclohexyl)3,4-piperidine, which binds to the phencyclidine (PCP) site in the ion channel of the NMDA receptor channel complex, revealed that NMDA receptor binding is not substantially altered in dystonic hamster brains compared to age-matched controls. Nevertheless, there was a tendency towards enhanced binding during a dystonic attack in several regions, including a 25% increase in the ventrolateral thalamic nucleus (P<0.05), which may be associated with altered basal ganglia output. While the data do not indicate widespread abnormalities in the PCP site of the NMDA complex, they do not exclude the possibility of more pronounced changes at other regulatory binding sites of the NMDA complex or other types of glutamate receptors in dystonia. 相似文献

An autoimmune hypothesis has been suggested for early onset obsessive-compulsive disorder and Tourette syndrome. The term: Paediatric autoimmune neuropsychiatric disorders associated with streptococcal infection (PANDAS) has been proposed as an aetiological subtype of OCD and TS, related to a Group A beta haemolytic streptococcal (GABHS) infection that triggers an autoimmune response. Antineural antibodies have been studied and found in the sera of some patients with these disorders, and they are thought to cross-react with streptococcal and basal ganglia antigens. The present study included 32 prepubertal-onset OCD patients, 21 with TS diagnosis (some of them meeting criteria for PANDAS) and 19 normal children, all aged between 9 and 17 years. Antibodies were assayed by immunohistochemistry and immunoblot. Special attention was paid to the methodology and a high serum dilution was used to minimize non-specific binding. No anti-basal ganglia antibodies were detected by immunohistochemistry in any of the samples. Two proteins, with approximate molecular weights of 86 kDa and 55 kDa, were found in sera from 7 patients. Though the study supports the hypothesis of an autoimmune process underlying OCD or TS in some patients, further research is needed. 相似文献

We describe a patient with the development of paroxysmal kinesigenic dystonic choreoathetosis (PKDC) after a thalamic infarct. PKDC consists of brief episodes of dystonia or choreoathetosis triggered by movement. PKDC improves with anticonvulsants, and in some cases, with L-Dopa or anticholinergics. We review PKDC, and relate its salient features to idiopathic and secondary torsion dystonia. We postulate a similar underlying pathophysiology. 相似文献

We describe here familial dyskinesia and facial myokymia (FDFM), a novel autosomal dominant disorder characterized by adventitious movements that sometimes appear choreiform and that are associated with perioral and periorbital myokymia. We report a 5-generation family with 18 affected members (10 males and 8 females) with FDFM. The disorder has an early childhood or adolescent onset. The involuntary movements are paroxysmal at early ages, increase in frequency and severity, and may become constant in the third decade. Thereafter, there is no further deterioration, and there may even be improvement in old age. The adventitious movements are worsened by anxiety but not by voluntary movement, startle, caffeine, or alcohol. The disease is socially disabling, but there is no intellectual impairment or decrease in lifespan. A candidate gene and haplotype analysis was performed in 9 affected and 3 unaffected members from 3 generations of this family using primers for polymorphic loci closely flanking or within genes of interest. We excluded linkage to 11 regions containing genes associated with chorea and myokymia: 1) the Huntington disease gene on chromosome 4p; 2) the paroxysmal dystonic choreoathetosis gene at 2q34; 3) the dentatorubral-pallidoluysian atrophy gene at 12p13; 4) the choreoathetosis/spasticity disease locus on 1p that lies in a region containing a cluster of potassium (K+) channel genes; 5) the episodic ataxia type 1 (EA1) locus on 12p that contains the KCNA1 gene and two other voltage-gated K+ channel genes, KCNA5 and KCNA6; 6) the chorea-acanthocytosis locus on 9q21; 7) the Huntington-like syndrome on 20p; 8) the paroxysmal kinesigenic dyskinesia locus on 16p11.2-q11.2; 9) the benign hereditary chorea locus on 14q; 10) the SCA type 5 locus on chromosome 11; and 11) the chromosome 19 region that contains several ion channels and the CACNA1A gene, a brain-specific P/Q-type calcium channel gene associated with ataxia and hemiplegic migraine. Our results provide further evidence of genetic heterogeneity in autosomal dominant movement disorders and suggest that a novel gene underlies this new condition. 相似文献

Effectiveness of lamotrigine in children with paroxysmal kinesigenic choreoathetosis 总被引:2,自引:0,他引:2
Paroxysmal kinesigenic choreoathetosis (PKC) is a rare movement disorder, characterized by recurrent, brief involuntary dystonic attacks that are provoked by sudden movements. Pathophysiology is uncertain, but a channelopathy is discussed. Treatment recommendations favour antiepileptic drugs (AEDs) acting on voltage-gated neuronal ion channels. This report summarizes the history of three children (6, 8, and 10 years of age) with idiopathic PKC successfully treated with low doses of lamotrigine, an AED acting primarily via neuronal voltage-sensitive sodium channels. 相似文献

Paroxysmal kinesigenic choreoathetosis is a rare neurologic disorder characterized by sudden attacks of brief involuntary dyskinetic movement that are precipitated by voluntary movement. A 14-year-old male who presented with frequent brief attacks of hemidystonia triggered by sudden movement is reported. Investigations, including video electroencephalogram and magnetic resonance imaging of brain, were normal. There was excellent and sustained response to carbamazepine. Ictal single-photon emission computed tomography using (99m)Tc ethyl cysteinate dimer revealed increased perfusion of the contralateral basal ganglia, which is associated with onset of choreoathetosis attacks. Our findings provide evidence that hyperactivity of the basal ganglia is associated with the dyskinetic attacks in paroxysmal kinesigenic choreoathetosis. 相似文献
