[Asymptomatic ischemic cerebrovascular disorders and neuroprotection with vinpocetine]


[The asymptomatic ischemic cerebrovascular disorders (AICVD) is an early manifestation of cerebrovascular disease. It is also known as latent insufficiency of the cerebrovascular circulation or as asymptomatic cerebrovascular disorders. Recently, the term subclinical disease, detected noninvasively, has been introduced by American Heart Association. The diagnosis is based on the following criteria: evidence of vascular risk factors; episodic nonspecific complaints without any focal cerebral symptoms; mild cognitive deficit, detected by neuropsychological tests; carotid ultrasonography often shows intimal-medial thickening, atherosclerotic plaques and carotid stenosis; CT and MRI occasionally reveal silent cerebral infarctions, white matter hyperintensities or cerebral atrophy; regional hypoperfusion above the ischemic threshold is also seen by rCBF measurements. Treatment of the AICVD, modifying the vascular risk factors and using neuroprotective agents, should be the cornerstone of primary prevention of ischemic stroke and cognitive decline, caused by cerebrovascular disorders. Vinpocetine has been found to interfere with various stages of the ischemic cascade: ATP depletion, activation of voltagesensitive Na+- and Ca++-channels, glutamate and free radicals release. The inhibition of the voltage-sensitive Na+- channels appears to be especially relevant to the neuroprotective effect of vinpocetine. Pronounced antioxidant activity of the drug could also contribute to the neuroprotection. PET studies in primates and man showed that 11C labelled vinpocetine passes the blood-brain barrier rapidly. Heterogeneous brain distribution of the compound was observed mainly in the thalamus, basal ganglia, occipital, parietal and temporal cortex, regions which are closely related to the cognitive functions. PET studies in chronic ischemic stroke patients revealed favourable effects of vinpocetine on rCBF and glucose metabolism in the thalamus, basal ganglia and primary visual cortex. It seems, vinpocetine, affecting the multiple mechanisms of the AICVD, could be of benefit for the treatment in this early stage of cerebrovascular disease. Vinpocetine may also become a new therapeutic approach to prophylactic neuroprotection in patients at high risk of ischemic stroke.]

[Diagnostic criteria and differential diagnosis of Parkinson’s disease]

TAKÁTS Annamária

[The clinical diagnosis of Parkinson’s disease is based on the identification of some combination of the clinical motor signs of bradykinesia, rigidity, tremor and postural instability. Three levels of diagnostic confidence are differentiated: possible, probable, and definite. The diagnosis of possible and probable Parkinson’s disease based on clinical criteria alone, while definite diagnosis requires neuropathologic confirmation. To differentiate Parkinson’s disease (idiopathic Parkinsonian syndrome) and other Parkinsonian syndromes is of increasing importance considering the therapy and life expectancy of the patients. Recently the functional imaging technics have been more and more helpful in the early differential diagnosis of Parkinson’s disease.]

[Clinical neurophysiological methods in diagnosis and treatment of cerebrovascular diseases]

NAGY Ildikó, FABÓ Dániel

[Neurophysiological methods are gaining ground in the diagnosis and therapy of cerebrovascular disease. While the role of the EEG (electroencephalography) in the diagnosis of post-stroke epilepsy is constant, quantitative EEG para-meters, as new indicators of early efficiency after thrombolysis or in prognosis of patient’s condition have proved their effectiveness in several clinical studies. In intensive care units, continuous EEG monitoring of critically ill patients became part of neurointenzive care protocols. SSEP (somatosesnsory evoked potencial) and EEG performed during carotid endarterectomy, are early indicative intraoperativ neuromonitoring methods of poor outcome. Neurorehabilitation is a newly discovered area of neurophysiology. Clinical studies have demonstrated the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in the rehabilitation of stroke patients. Brain computer interface mark the onset of modern rehabi-litation, where the function deficit is replaced by robotic tehnology. ]

[Neuropsychological rehabilitation following acquired brain injury]

TAMÁS Viktória, KOVÁCS Noémi, TASNÁDI Emese

[Neuropsychological rehabilitation or rehabilitation neuropsychology is a field within applied neuropsychology. It originally diverges from applied clinical and functional neuropsychology, although it could not be entirely differed from them. The unique nature of this area over the complexity is given by its process-controlled and system-approach aspects. In Hungary the number of neurorehabilitation centres and departments requiring neurocognitive rehabilitation has been continually increasing. Nevertheless, the number is still low; accordingly in our country this field is relatively young and isn’t well known. Authors of this review would like to draw attention to the importance of rehabilitation of patients with acquired brain injury and improvement of their quality of life with the theoretical and practical knowledge, as well as the necessity of future alterations and challenges emphasizing the need of a significant change of this narrow domain. ]

[Organization of rehabilitation of people with disabilities as a consequence of neurological conditions in Hungary]

FAZEKAS Gábor, DÉNES Zoltán, FÁY Veronika, URBÁN Edina, SZÉL István

[The history of rehabilitation of people with disabilities as a consequence of neurological conditions goes back to more than four decades in Hungary. The authors describe its history, how this service is organized nowadays, questions of specialization, scientific activity and quality improvement. They emphasise: any form of neurorehabilitation service (special neurorehabilitation department or programme of a multiprofile rehabilitation unit) must meet the same criteria. Quality assurance will be provided by a new accreditation system.]

[Plasticity of brain lateralization in epilepsy: fMRI studies]

KALMÁR Zsuzsanna, WOERMANN Friedrich, SCHWARCZ Attila, JANSZKY József

[Aims - This review is a summary of four studies investigating the effect of epileptic disturbance and other functional factors on the brain lateralization. Methods - Patients were investigated by functional MRI by using visual, sensorimotor, memory, and speech paradigms. Results - 1. Malformations of cortical development localized within speech centers induce contralateral speech reorganization in only 50% of cases. 2. Epileptic disturbance can induce a reorganization in language lateralization independent of the effect of lesion. 3. Bilateral epileptic activity can prevent a reorganization of memory functions contralateral to the seizure onset region. 4. Injury of the right upper limb can induce a left-to-right shift of language lateralization. Conclusions - Our results may have implication during neurorehabilitation process and neurosurgical interventions. Participation of malformations of cortical development in cognitive functions should keep in mind during surgery. Reorganization of speech- and memory functions should also be considered during operations of central nervous system.]

[We have read several publications of great authority on the neurological profession in the last two years in which were expressed assessments of the current situation combined with opinions about neurology and the necessity to reorganize neurological patient care. These articles took up the question of neurorehabilitation too. The authors, who on a daily basis, deal with the rehabilitation of people with disabilities as a consequence of neurological conditions, summarize some important definitions of rehabilitation medicine and the present system of neurological rehabilitation, as it is defined by the rehabilitation profession.]
