Clinical Neuroscience - 1994;47(11-12)

[ln the late sixties the revelation that more than half of the dementia cases in elderly people were caused by Alzheimer's disease and not by „cerebral arteriosclerosis" gave dementia research a new impetus, which accelerated in the eighties and has nowadays become explosive and has supplied us with a mass of data almost beyond comprehension. Nevertheless, even though it is most intensively, studied elucidation of the etiology and pathogenesis of the Alzheimer' s disease is still not expectable in the near future. ln addition to Alzheimer's disease, new results basically changing our views, have been achieved in the field of the vascular dementia and in dementias with Parkinsonian syndrome. Frontostriatal circuits discovered recently have helped our understanding of the subcortical dementia in these diseases and in others. By means of neuroimaging techniques, several dementia syndromes - paramedian thalamic infarcts, the watershed infarcts and the so called Binswanger's disease - have turned out to be much more common than previously believed. Clinicopathological observations have verified the role of the damage to the limbic and paralimbic structures, frontostriatal circuits and association pathways in the pathomechanism of dementias. ]

[Typical behavior models of dealing with epilepsy - the models present between patient and members of the family]

RAJNA Péter, NEMESSÚRI Judit, TÖLGYES Tamás, VERES Judit

[Four are main symptom groups described which were previously considered to be not more than an organic consequence of epilepsy. In most cases in the background of these groups a pathogenic/ pathogenetic role of typical relationship constellations between the patient and his/her relatives can be observed. These constellations are illustrated by case descriptions. It is pointed out that: 1. Epilepsy is a chronic illness in the course of which in every case certain psychodynamic events take place between the patient and his or her relatives in the immediate environment. 2. According to the present „neurological" approach and to the social expectations in the course of the patients' care the main stress is on biological events and changes. As a result intrapsychic and social-psychiatric motives are frequently manifested in the form of biological symptoms, too. 3. It follows from the above that the psychic constellation is interiorized by the patient and then he/she expresses it through somatic symptoms. At first sight these symptoms seem to be typical epileptic problems”. In actual fact, somatic „epileptologic” treatment cannot be regarded as succesful. 4. Since care is mainly based on auto- and heteroanamnestic data the phenomena discussed earlier could be highlighted only by means of the simultanious exploration of the family in question and by possible disagreement between the patient and his/her environment. 5. In order to treat the epileptic patient it is essential to consider the illness in relation to the patient and the members of the family.]

[Characteristics of gadolinium-enhancement in ischemic stroke]

BARSI Péter, KENÉZ József, NAGY Zoltán, KULIN Árpád

[Stroke is a clinical diagnosis. In acute stroke, CT is the first examination of choice to exclude hemorrhage. In ischemic stroke, MR detects the changes earlier and more exactly, than CT. Contrast-enhanced MR imaging shows specific enhancement phenomena, viz. Intravasal high signal in the vessels of the ischemic cerebral region, meningeal enhancement, transitorial, mixed type enhancement and parenchymal enhancement. Our paper is deals with the causes and diagnostic significance of the different types of these enhancement effects, and discusses some differential diagnostic conclusions. In the near future, after installing more modern MR equipment, a more exact knowledge of the pathomechanism of stroke and, as a consequence, new and more effective therapies can be expected.]

[Determination of serum C-reactive protein in the illnesses of central nervous system]

PINTÉR Erzsébet, KÁLI Gábor, VUKMIROVITS György, NIKOLOVA Radka, YOUSEF M. Gassar, GYARMATI Éva

[Serum quantitative C-reactive protein concentrations were measured in 186 patients admitted with suspected neuroinfection or symptoms of other diseases in the central nervous system. The diagnoses were purulent meningitis (102), abscessus cerebri (5), meningitis basilaris (2), meningitis cryptococcica (1), sepsis (11), encephalitis (22), encephalopathia (5), autoimmune central nervous illness/disease/disorder (22), non-inflammatory central nervous disease/ disorder (12) and tumour cerebri (4). The highest values of C-reactive protein were measured in patients suffering from abscessus cerebri (250.8 +/ 64.2 mg/l), sepsis (221 +/- 16.4 mg/l) and purulent meningitis (153.0 +/- 94.59 mg/l). Serum C-reactive protein concentrations were moderately increased in viral infections (36.8 +/- 36 mg/l). The C-reactive protein level in the normal range in patients suffering from non-inflammatory and autoimmune central nervous illnesses/diseases/ disorders (4.0 +/- 1.5 mg/l or 10.0 +/- 18.5 mg/l). During our examinations the C-reactive protein levels showed both local and septicaemic reactions. C-reactive protein is considered as a valuable laboratory parameter both in diagnosings central nervous system diseases with suspected bacterial infection and in monitoring therapeutic efficiency.]

[Chronic recurrent transverse myelitis or multiple sclerosis]

VÉCSEI László, DIBÓ György, UNGUREÁN Aurélia, PÁLFI Sándor

[The simultaneous appearance of multiple sclerosis and transverse myelitis is a known phenomenon. Apart from the appearance of spinal symptoms, other neurological signs of the brain involvement can urually be found, MRI shows disseminated foci in the brain. The positive evoked responses, the immunological abnormalities of the CSF, and the oligoclonality together prove the presence of multiple sclerosis. In these cases the symptoms of transverse myelitis may precede other signs of multiple sclerosis, or appear separately as a relapse. Recurrent transverse myelitis as an independent entity with negative MRI and CSF immunology, is an exciting topic concerning the etiologic factors and therapeutical considerations. Tvolging from the literature, the appearance of transverse myelitis as an independent entity, is rather rare. Details are given of a female patient with recurrent spinal cord signs, negative MRI and CSF immunology. During her ten-year follow-up no, symptoms of multiple sclerosis have developed. Further studies are needed to clarify the etiological factors, pathomechanism and therapeutic considerations of this relatively new and probably independent clinical entity.]

[Trial to verify the link between onset of epileptic seizures and complex meteorological changes, pilot study]

RAJNA Péter, CSIBRI Éva, BÁRTFAY Réka, BÁRTFAI Erzsébet

[In this pilot study parameters are found that suggest a possible link between the onset of epileptic seizures and meteorological changes. The meteorological conditions were divided into 7 different levels in terms of their sympathetic/ parasympathetic effect and were related to the onset of 816 epileptic seizures of 15 patients. The possible epileptogenic effect of rapid (within 12 hours) meteorological changes was also evaluated and 48-hour periods before and after a given seizure were also considered. A trend was found in the distribution: within two days preceding seizures parasympathetic effects tended to be predominant, within those following seizures sympathetic effects tended to dominate. Surprisingly, rapid meteorological changes did not play significant role. More essential data were obtain in individual evaluations. In just every 4th patient the sympathetic or the parasympathetic effect was predominant before the seizure onset and in just every 3rd person rapid meteorological changes culminated in the pre- or in the post-seizure 48-hour interval. The most frequently occuring meteorological effect on the day of seizures was sympathetic. It is thought that these parameters might be appropriate to demonstrate the possible link. Even so, preference is given to individual evaluation which might have an additional therapeutic significance, too.]

[Role of platelet function in the pathogenesis of alzheimer's disease]

HASITZ Mária, LIPCSEY Attila, RÁCZ Zoltán

[Dementias, especially those of Alzheimer type represent very serious types of disease in the elderly. Amounting evidence suggests that Alzheimer's disease is reflected in the platelets of the patients. Our results and the data of scientific literature have been summarized. In vitro parameters of platelet shape and aggregation were compared. Platelet shape, characterized by aggregometer oscillation amplitude, and the initial rate of 50 uM ADP-induced aggregation have been recommended for supporting the diagnosis of Alzheimer's disease or Alzheimer-type senile dementia. Our results and those of others revealed that the function of the Alzheimer platelet is influenced by two effects: the plasma medium and the genetic background resulting in the change of the platelets. The results suggest that both effects are involved in the vitro functions detected.]

[NEUROPATHOLOGICAL EXAMINATIONS IN AUTOPSIES WITH SPECIAL FOCUS ON FINDINGS IN ALZHEIMER’S DISEASE]

LEEL-ŐSSY Lóránt, SZŰCS Iván, KINDLER Miklós, SCHWARCZ Tibor

[Out of an average total of 1400 autopsies per year, neuropathological examinations were performed in 477 cases between 1997 and 1999 to investigate the incidence of dementias. The majority of the studied subjects were over 50 years old. Bielschowsky's and/or Gallyas's silver methods and, in some cases, protein tau (MAP) immuncytochemistry and amyloid staining were performed beside routine examination. Pathological changes were found in 212 of the 364 cases studied by the above methods but histological changes associated with dementia were only detected in 167 cases. The various forms of Alzheimer's dementia were also classified by age. The "incipient" form of Alzheimer's disease was verified in 23 cases. Old infarcts of various extensions were found in 42 percent of Alzheimer's dementias. Very mild or age-related degenerative changes were observed in 82 cases among subjects over 50 years old. Of these, eight patients died in their 90s. In some cases (n=38) the number of neuritic plaques dominated over the number of neurofibrillary tangles but a reverse finding also occurred (n=13). Neuronal degeneration was variable and was not always proportional to the number of neurofibrillary tangles. "Simple type of senile atrophy" was defined by the presence of minor or age-related Alzheimer changes and was considered a separate entity. The "incipient" form of Alzheimer's dementia was diagnosed in relatively young individuals where mild Alzheimer changes were found at the neuropathological examination. "Preclinical" Alzheimer's dementia could only be suspected by clinical data and could very rarely be supported by the neuropathological finding of "incipient" form. The ratio of pure Alzheimer’s to vascular dementias cases proved to be 54:41 in this study. The results suggest that dementias are considerably underdiagnosed both in the clinical and pathological practice and that the recently defined "preclinical" and "incipient" forms are very hard to recognize both clinically and pathologically. The neuropathological study of the degenerative, mainly Alzheimer's type, findings in the randomly selected autopsies revealed great variations which raises many questions concerning the normal and pathologic aging of the brain as well as the "incipient" and senile forms of Alzheimer's dementia.]

[Hypertension and cognitive feature]

KISS István, KÉKES Ede

[Around authors of the literature data and our own experience of the relationship between hypertension and cognitive function. The age progresses, more and more of the dysfunction and vascular dementia. This plays a significant role in hypertension. Simple methods, tests you should regard the practice and also check this function, considering that the aging population is an unstoppable process. The effective antihypertensive treatment, blood pressure variability reduction positively affected by the deterioration of the cognitive function, especially if treatment is started as soon as possible.]

[P300 wave evoked by visual and acustic stimuli in parkinsonian patients with or without dementia]

MOGYORÓS Ilona, SZOMBATHELYI Éva

[Authors analysed the relationship between cognitive function disturbance observed in patients with Parkinson's disease and clinical features of the disease. Relationship between the latency prolongation of the P 300 wave and the duration of substitution therapy, clinical form and severity of the disease (the Hoehn-Yahr stage) was examined. 75 randomly selected young patients with Parkinson's disease were divided in to two groups: one with and the other without dementia as determined by the Wechsler. Hunt and Mini Mental State tests. The latency of the P 300 wave using visual and acoustic stimuli was determinated. Significant prolongation of the latency of P 300 wave evoked both by visual and acoustic target stimuli was found in parkinsonian patients with dementia. Patients with dementia have longer duration of disease and substitution therapy. The akinetic-rigid form of the disease was more frequent in this group as well. A significant part of younger patients are chacarterised not only with motor but with cognitive function disturbance, too. Determination of the latency of P 300 wave helps to select these patients and to choose the adequat therapy. ]
