[Occipital spectral EEG-parameters in newly diagnosed, untreated epilepsy patients]

CLEMENS Béla, BESSENYEI Mónika

[Introduction - Minor spectral EEG alterations hidden to the naked eye may be of interest in the field of epileptology, cognitive performances, and drug effects. In order to introduce new scientific results of brain wave research into the clinical field of epilepsy- and drug-related cognitive problems, a normative quantitative EEG database for epilepsy was constructed. Patients and methods - 171 newly referred, five to 50 years old patients with untreated ”new” epilepsy (that is, clinical, EEG, MRI investigations had been done in 24 months after the first unprovoked seizure) were collected. EEG was recorded with closed eyes, in the waking-relaxed state. Effects that are known to influence EEG spectra (nearby seizures, drugs, etc.) were excluded as far as possible. A total of two minutes of waking-resting EEG activity was chosen for spectral analysis. Fast Fourier transformation of the selected samples were calculated resulting in absolute power, percent power and mean alpha frequency (AA, RA, and AMF respectively) for the right and left occipital derivations. For each patient (and also for 37 healthy controls), the deviation of the individual values from the age-adjusted normative mean was expressed in Z-score. Main diagnostic epilepsy categories were compared to the control group as well as to each other. In addition, effects of MRI-defined cerebral lesions and interictal spiking on spectral EEG parameters were investigated. Results - All group averages were within the 95 per cent confidence interval. Overwhelming majority of the individual data fell within a 3Z range. Statistically significant differences were found for AA and RA, but seldom for AMF. Right and left alpha-parameters were surprisingly symmetrical in all groups. The main difference between epilepsy groups and controls was less AA and RA power in the epilepsy groups. MRI-defined lesions and interictal epileptiform activity did not significantly influence EEG spectral variables. Conclusion - These results might serve as reference data and might help planning of further quantitative EEG studies in the triangle of epilepsy, cognitive problems, and drug effects.]

[Neuropsychological applications of the Rey Complex Figure and Recognition Test]

F. FÖLDI Rita, TOMASOVSZKI László

[The authors describe the clinical applications of the Rey Complex Figure and Recognition Test and explain how the individual abilities and information-processing characteristics are reflected. Sequential and quantitative evaluation methods are presented. Summarizing the relation between IQ and RCFT they evaluate the differencies in task completion strategies of healthy subjects and subjects with brain damage, suggesting that these differences originate in changes of the information-processing capacity. Application of the RCFT in clinical child psychology is also suggested, primarily in differential diagnostics of children with attention disorder and disruptive disorder. The authors illustrate the protocols of the neuropsychological examination and the role of the RCFT with a case study.]

[Faces from the Hungarian Nursing Hall of Fame: the exemplary careers of two Hungarian recipients of the Florence Nightingale Medal]

SÖVÉNYI Ferencné, PERKÓ Magdolna, FEDINECZNÉ VITTAY Katalin, BOROS Károlyné

[In their pervious article, authors described how the Florence Nightingale Medal came to existence and provided a list of Hungarian nurses whose achievements were honoured by the Medal between 1920 and 2003. In this contribution, they review the lives and careers of Baroness Gizella APOR and Ms. Ilona DURGÓ, two Hungarian nurses who were awarded the Medal in 1920 thus being among its first recipients globally.]
