[A method of speech rehabilitation by computer aided synthesized speech is reported. This method is useful in patients with severe dysarthria, dysphonia and motor aphasia, when agraphia and alexia are not present. The improved communication helps the patients to adapt to their milieu and decreases social isolation. A case history is given of a patient who uses this method successfully during her daily activities. The speech therapy was significantly supported by the use of computer for synthesized speech. The 48-year old woman underwent a cardiac operation (implan tation of artificial valve) due to previous myocarditis and mitral insufficiency before the present neurological complication. She suffered multiple ischemic attacks leading to the loss of motor performance of speech.]

[Repeated stroke, psychotic episode - primary antiphospholipid syndrome?]


[The antiphospholipid syndrome described some 10 years ago is characterized by a predisposition to arterial and venous thrombosis and the presence of antiphospholipid antibodies. It is often associated with systemic lupus erythematosus, but its primary forms are also well known. Its clinical features are well known in neurology as well as in psychiatry. In this paper we present a case report with therapeutic implications. We discuss the importance of reccurent stroke at a young age in association with the possibility of a rare manifestation of antiphospholipid syndrome: organic brain disease, appearing in the form of schizoaffective psychopathological symptoms.]

[Cluster headache and its treatment]


[Cluster headache, one of the most painful conditions known, is encountered infrequently in clinical practice. It is characterized by recurrent, unilateral attacks of severe intensity, brief duration and often accompanied by signs and symptoms of autonomic dysfunction. The actual cause of the pain has not been fully elucidated, but most authors believe that the pain arises as a result of a local vasodilatation with a release of certain neuropeptides to the perivascular tissues, resulting in sterile neurogenic inflammation and oedema. Aetiology is absolutely unknown. Treatment can be given as prophylaxis and/or as a symptomatic acute therapy for individual attacks. In the prophylaxis of episodic cluster headache ergotamine, calciumentry blockers, serotonin inhibitors and steroids are used. In chronic cluster headache lithium is the drug of choice, but verapamil may also be tried. Acute therapy has included ergotamine, oxygen inhalation and sumatriptan. Rarely, surgical intervention may be considered.]

[Experiences with sumatriptan in the treatment of Cluster headache]


[Subcutaneously administered sumatriptan 6 mg is rapid, effective and well-tolerated for the acute treatment of cluster headache. Efficacy is maintained in long-term use. The authors report the results of the 5HT1 receptor agonist sumatriptan autoinjector in the treatment of 350 attacks in 20 cluster patients. After 20 minutes post injection the complete dissolution of headache was reported in 95% of the attacks. Slight and transient side-effects were experienced therefore non of the patients were discouraged from using the autoinjector device again. It is essential in the improvement of the quality of life of patients suffering from cluster headache.]

[Quantitative monitoring of EEG variability following subarachnoid hemorrhage]


[Cerebral vasospasm causing focal ischemia is a frequent complication following subarachnoid hemorrhage. Monitoring of EEG may help to reveal hemispheric dysfunction in the postoperative period. Continuous monitoring of EEG was performed on 8 bipolar channel in 30 patients with subarachnoid hemorrhage during the first two weeks after aneurysm rupture. Computerized trend analysis of 8–16 hours long periods was made. Variability of relative alpha power was evaluated visually on a 4 grade scale and it was also measured quantitatively. EEG data were compared with daily transcranial Doppler values and clinical state. Symptomatic vasospasm was detected in 16 patients while other neurological complications developed in a further 4 cases during monitoring. Significant decrease of variability was observed in all of them. This change developed 1-2 days before other signs of vasospasm in 10 patients. The onset of variability decrease was unilateral in 4 cases. No remarkable decrease of variability was found in patients without neurological complication. Our data confirm that EEG monitoring is a useful tool for sensitively detecting deterioration of brain function. Relative alpha variability is an indicative EEG parameter that can signify hemispheric dysfunction caused by ischemia in an early subclinical stage, when still no Doppler signs of vasospasm or deterioration of clinical symptoms occur.]

[Intravenous perfusion anaesthesia in neurosurgey part two]


[A retrospective analysis of 1300 neurosurgical perfusion narcoses performed by means of intravenously administered propofol-fentanyl-vecuron proved the advantage of this technique over traditional procedures. It decreased the recovery time, the incidence of postoperative nausea and vomiting, and muscle fibrillation. Propofol did not elevate either raised or normal intracranial pressures. Moreover, a trend reduction of raised ICP was observed. The incidence of cardiovascular complications was also reduced. Patients, especially the elderly, had a quick, subjectively well-tolerated induction of sleep and recovery. Comparison of parameters of propofol general anaesthesia with those of "combined balanced narcosis" and "perfusion ataranalgesia” statistically proved the significantly advantage of this new method. The conclusion has been drawn that propofol was a most appropriate drug for neurosurgical anaesthesia. ]

A rare condition mimicking stroke: Diabetic uremic encephalopathy

TEKESIN Aysel, ERDAL Yuksel, MAHMUTOGLU Soydan Abdullah, HAKYEMEZ Ahmet, EMRE Ufuk

Uremic encephalopathy (UE) is a metabolic disorder associated with acute or chronic renal failure. It is characterized by the acute or subacute onset of reversible neurological symptoms and specific imaging findings. It is uncommon for uremic encephalopathy to be associated with acute bilateral lesions of the basal ganglia in diabetic uremic patients, and this can be seen most often in Asian patients. Here, we report a patient with diabetic uremic encephalopathy and bilateral basal ganglia lesions who developed acute onset dysarthria. The clinical and magnetic resonance brain imaging findings resolved after hemodialysis treatment.

[The Comprehensive Aphasia Test in Hungarian]


[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


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.

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]
