BACKGROUND Biofeedback is a modern computer-related technique used for assessment and therapy of many psychophysiological disorders, especially stress-related ones. After a short overview of the basic concepts of biofeedback, in this study the application of EEG biofeedback (neurofeedback) in the assessment of and therapy for attention deficit hyperactivity(More)
BACKGROUND Autistic spectrum disorders are a group of neurological and developmental disorders associated with social, communication, sensory, behavioral and cognitive impairments, as well as restricted, repetitive patterns of behavior, activities, or interests.The aim of this study was a) to analyze QEEG findings of autistic patients and to compare the(More)
The possibility that memory is related to the collective rotational energy levels of the molecules is considered. Treating the molecule as a quantum rotator, the probability of the ''hidden-crossing'' transitions between rotational states, induced by the external periodic electric field, is analyzed. It is found that this probability depends on frequency(More)
Hereditary multiple exostoses (HME) is an inherited autosomal dominant disorder characterised by the presence of multiple exostoses, in fact benign cartilaginous tumors (enchondromata on the long bones). A six-year-old boy was found to have multiple osteochondromas on the legs, arms and ribs. Unusually, one of the osteochondromas on the right arm was huge(More)
BACKGROUND Infants with cystic fibrosis (CF) can develop episodes of hyponatremic hypochloremic dehydration with metabolic alkalosis when they sweat excessively, which is not caused by sweating in normal infants. We investigated the incidence of the metabolic alkalosis with hypoelectrolytemia in CF infants, the possible risk factors for its occurrence and(More)
BACKGROUND Anorexia and bulimia nervosa are considered to be the most serious eating disorders in female adolescents, with a multifactorial etiology and severe medical complications. It is interesting to investigate the specific relationships of these diseases to emotional stress, coping mechanisms and biofeedback mitigation. METHODS The study comprised(More)
Our previous research on basic and applied psychophysiology comprised the quantum model for subcellular brain processes, the psychosomatic health risk assessment and management, as well as the electrodermal biofeedback psychometrics and therapy. Based on this experience, in the present paper the stress-related psychophysiological disorders in patients(More)
The spondylocostal dysostoses (SCDs) are a heterogeneous group of axial skeletal disorders characterized by multiple segmentation defects of the vertebrae (SDV) and abnormality of the thoracic cage with mal-aligned ribs and often a reduction in rib number. The four known monogenic forms of SCD follow autosomal recessive inheritance, have generalized SDV, a(More)
Psychogenic nonepileptic seizures are operationally defined as episodes of altered movement very like epileptic seizures, but associated with psychological problems and not with ictal discharges. Children with psychogenic nonepileptic seizure (PNS) could be categorized either under somatoform in the ICD-10 or conversion disorders in DMS-IV. The history,(More)
(Full text is available at http://www.manu.edu.mk/prilozi). Continous Performance Tests (CPTs) form a group of paradigms for the evaluation of attention and, to a lesser degree, the response inhibition (or disinhibition) component of executive control. The object of this study was to compare performance on a CPT using both visual and emotional tasks in 46(More)
