[Parkinson's syndrome and cognitive disorders]
[The cognitive (executive) ability of patients with Parkinson’s-disease (PD) deteriorates gradually during the progression of the disease. Fluency of speech, word finding, working memory, ability to plan the future and flexibility decline. Cognitive disturbance was found to be proportional with the speech, posture, gait and balance problems and can not be influenced by L-dopa substitution. Apart the dorsal and ventral mesolimbic dopaminergic systems the coerulo-cortical noradrenergic,... tovább »

[Investigation of the dopamine dysregulation hypothesis of schizophrenia with neuroimaging techniques]
[The most elaborated biochemical concept of schizophrenia is the dopamine hypothesis. However, this classical theory is based on indirect observations. It has recently become possible to study this theory directly by means of advanced functional neuroimaging techniques, the development of specific radioligands and study protocols that are eligible to monitor dynamic changes in the neurotransmitter systems. According to the early concept, the essence of schizophrenia is the hyperactivity of the... tovább »

[Cerebellar venous anomalies with symptomatic vascular malformations]
[Cerebral and cerebellar venous anomalies (previously known as venous angiomas) form the alternative venous drainage of the surrounding nervous tissue because of the un-development of the normal venous system. They are made up of veins with abnormal structure: thick walls, lumens dilated and of irregular calibre that converge radially towards a wide draining vein (caput medusae). They are thought to be a benign condition although they are sometimes associated with cerebellar hemorrhages.... tovább »

[Percutaneous procedure for treatment of diseased vertebral bodies with different etiology: vertebroplasty]
[Percutaneous vertebroplasty is a radiologically guided invasive technique consisting of the injection of surgical cement into the diseased vertebral body. The procedure results in immediate pain relief and strengthening of the bone due to the polymerization process of the filling material hardening the vertebral body and preventing further collapse. This method is suitable for the treatment of osteoporotic vertebral fractures and of osteolytic vertebral body metastases without neurological... tovább »

[The molecular genetic control of bony developmental malformations affecting the craniocervical junction and the cervical spine]
[In this review a new interpretation of the origin of bony developmental malformations affecting the craniocervical junction and the cervical spine is presented based on recent advances in the understanding of embryonic development of the spine and its molecular genetic control. Radiographs, CT and MRI scans or CT myelograms of patients with Klippel-Feil syndrome were used for demonstration. Detailed clinical and radiologial analysis of these patients was published earlier [David KM, Stevens... tovább »

[Neuropsychological outcome following bilateral pallidotomy in patients with Parkinson's disease]
[Introduction - Although significant improvement of motor function following bilateral pallidotomy for the treatment of Parkinsons's disease has been proved, the cognitive sequalae have not been clearly defined. There are recurrent loops interconnecting specific areas of the frontal cortex and the basal ganglia, suggesting the continuity or complementary functioning between these areas. Patients and methods - Pre- and postoperative cognitive function was evaluated in 19 Parkinsonian patients... tovább »

[Application of kinematic parameters for the assessment of impairments due to central motoneuron damage]
[Evidence based medicine requires objective methods for the assessment of status of the patients. The method described by the authors makes it possible to assess motoric impairment of patients in an objective way. It is based on three-dimensional motion analysis. Authors present the case history of two patients with spastic hemiparesis due to central nervous system damage. Changes in motoric impairment were followed by three-dimensional motion analysis. This method can be adapted for the... tovább »
