[Spasticity, as a result of cortical motor neuron injury, is a frequent symptom in neurological disorders. Tolperisone is a centrally acting muscle relaxant, which has been used for 50 years in clinical practice. Tolperisone has a membrane-stabilising effect and it inhibits voltage-gated sodium and calcium channels. Although it targets the central neural system, it has no sedative side effects, in contrast to other muscle relaxants. Besides clinical experiences of past decades, the efficacy of tolperisone has also been proved in a study fulfilling evidencebased criteria. In this double-blind, placebo- controlled, randomised, parallel group study, 78.3% of tolperisone-treated patients had an at least one-point reduction on the Asworth scale (a 5-grade scale used the measure spasticity), compared with 45% in the placebo-treated group. The excellent tolerability of tolpe-risone is demonstrated by the finding that the number of adverse events was greater in the placebo group than in the tolpe-risone group. Taking these facts in consideration, tolperisone is a safe and effective drug to treat spasticity.]

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

The applications of transcranial Doppler in ischemic stroke

FINNSDÓTTIR Herdis, SZEGEDI István, OLÁH László, CSIBA László

Background: This overview provides a summary of the applications of transcranial Doppler (TCD) in ischemic stroke. Results: A fast-track neurovascular ultrasound protocol has been developed for detecting occlusion or stenosis. The technique is more reliable in the carotid area than in the posterior circulation. By monitoring the pulsatility index the in­crea­sed intracranial pressure can be diagnosed. TIBI score was developed for grading residual flow. TCD has been shown to accurately predict complete or any recanalization. Regarding recanalization, TCD has a sensitivity of 92%, a specificity of 88%, a positive predictive value of 96%, a negative predictive value of 78% and an overall accuracy of 91%, respectively. Sonothrombolysis seemed to be a promising application but randomized controlled trials have shown that it does not improve clinical outcome. TCD examination can detect microembolic signals (MES) which are associated with an increased risk of stroke. Micro­em­boli were detected in symptomatic and asymptomatic carotid artery stenosis and during carotid endarterectomy. The number of microemboli can be decreased by antithrombotic therapy. Contrast en­chan­ced examination and Valsalva maneuver with continuous TCD monitoring can accurately screen for right-to-left shunt.

[50 years of tolperisone in clinical practice]

BÁLINT Géza

[Tolperisone is a centrally acting muscle relaxant that has both antispasticity and antispasmodic properties, but lacks the sedative effect of other muscle relaxants. In the past 50 years, millions of patients with spasticity due to neurological diseases and painful reflex muscle spasm have been treated with this drug. Although few welldesigned, double blind, controlled clinical trials have been published, the efficacy of tolperisone in the treatment of both spasticity and painful reflex muscle spasm is convincing. The tolerability and safety of the drug are well documented. In this respect, one of its greatest advantages is that it has no sedative effect, does not lengthen reaction time, and does not interfere with driving. Further, well-designed controlled trials are clearly required for widening the use of this excellent drug.]

Hyperhomocysteinemia in female migraineurs of childbearing ages

ALEMDAR Murat, SELEKLER Macit Hamit

Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[Results of intrathecal baclofen therapy on spasticity in patients with brain injury]

DÉNES Zoltán, KLAUBER András, BOTH Béla, ERÕSS Loránd

[Objectives - To evaluate the results of intrathecal baclofen (ITB) therapy on the spasticity in patients with brain injury. Method - Retrospective study in Brain Injury Rehabilitation Unit between January 2001 and December 2010. Results - During the last ten years, in our unit 13 patients were involved into ITB therapy on severe spasticity, after brain injury, while more than 100 Baclofen pumps were implantated in Hungary with Hungary with coordination of the Multidisciplinary Team. ITB therapy was indicated in severe spasticity developed after seven cases of traumatic brain injuries, five cases of strokes and one case of anoxic brain injury. The mean age of patients was 26 years (18- 52). At the time of pump implantation three patients were in vegetative state. The shortest period elapsed between the brain injury and pump implantation was three months and the longest period was nine years, mean 15 months. Baclofen pump had to be changed in six cases after six years, and was removed in three cases due to decreasing spasticity. Catheter revision was performed in two cases due to flow problem. We had no complication in association with ITB therapy. Conclusions - Intrathecal baclofen therapy seems to be an effective and safe treatment in patients with severe spasticity of cerebral origin. We suggest team (neurosurgeon and rehabilitation professionals) decision in a spasticity center before involving the patient into ITB therapy, and follow up in the rehabilitation unit. The severity of spasticity as a consequence of brain injury can change during years and it is necessery to follow it with dosage and dynamics of baclofen therapy. Baclofen pump removal is suggested if the ITB therapy is further not reasonable.]
