We propose a new method, based on fractal analysis of EEG signal, of asessing phototherapy results in patients with Seasonal Affective Disorder (SAD). We demonstrate that the changes of the proposed parameter highly correlate with assessment of patients’ therapy using Hamilton Depression Rating Scale (HDRS).
Analysis of EEG-signal using methods of nonlinear dynamics and deterministic chaos theory may supply clinicians with effective quantitative descriptors of underlying nonlinear dynamics and chaos in the brain, so helping in neuro-psychiatric diagnosis and in assessing applied therapy. Howeve r, calculation of „standard” chaotic quantifiers requires long(More)
Alumina cream epileptic focus was established in the right sensorimotor cortex in 20 split-brain cats (partial or complete). EEG and behavioral observations were made in a period ranging from 24 to 836 days. Four types of EEG changes after alumina cream injection were differentiated. These types could be related to the direct effects of brain damage and to(More)
Juvenile myoclonic epilepsy (JME) is a common idiopathic generalized epilepsy (IGE); it has a clinical and probably a strong genetic relation to the other IGE forms. Generalized spike/polyspike-wave discharges (SW/PSW) are typical of all IGEs. The aim of our study was to determine the incidence of epilepsy and SW/PSW in EEG of family members of 12 JME(More)
The development of the clinical and EEG manifestations of intracortical alumina cream epileptogenic lesion is described in 14 split-brain cats. In 4 animals contralateral and/or ipsilateral, cortical and subcortical secondary epileptic foci were present. The results indicate that integrity of interhemispheric transfer through the corpus callosum and(More)
The authors report the preliminary results of determinations of motor activity of cats receiving 5'5-diphenylhydantoin. The determinations were carried out by means of a special device recording all movements of the animals to ensure objective evaluation. Healthy cats were used for these experiments. They were giving DPH in doses up to 12 mg/kg daily, the(More)
