In 81 depressed children aged 3 to 14 years the nonepileptic attacks could manifest the different psychopathological phenomena: 1, headaches before and after spells, non-systemic++ vertigo with imbalance and oculovestibular events with or without loss of consciousness; 2, orthostatic symptoms, syncope, cataleptoid seizures, Kloos seizures; 3, depersonalization and derealization episodes, deja vu and jamais vu states; 4, attacks with pain in the stomach and other organs, various other autonomic signs; 5, unsteady neurological signs: pareses, sensory, visual and speech disorders; 6, nightmares, oneiroid states, sleep-walking; 7, convulsive states, hyperkinesis; 8, psychomotor excitation and inhibition states; 9, behavioral spells with aggression. These states are differentiated from epileptic and hysterical attacks.

Aging is a physiological process that shares many behavioral, biochemical and neuroendocrine phenomena with the pathophysiological situation of unresolved stress, as well as with a pharmacologically induced syndrome resulting from chronic benzodiazepine (BZ) consumption. Behavioral findings include symptoms such as drowsiness, ataxia, fatigue, confusion, weakness, dizziness, vertigo, syncope, reversible dementia, depression, impairment of intellectual, psychomotor and sexual function, agitation, auditory and visual hallucinations, paranoid ideation, panic, delirium, depersonalization, sleepwalking, aggressivity, orthostatic hypotension, and insomnia. Neuroendocrine findings include: central depletion of noradrenaline (NA), dopamine, adrenaline (AD), and serotonin (5-HT); reduction in the ratio of circulating NA/AD as well as platelet 5-HT and increase of AD, plasma free 5-HT and cortisol. These disturbances together with the increased platelet aggregability observed in the three groups are typical of unresolved-stress situations. Immunological findings include significant reduction of peripheral T lymphocytes (CD3, CD4, CD8) and the CD4/CD8 ratio, CD16 and gamma-delta cells. On the other hand, the three groups (elderly subjects, subjects faced with unresolved stress, and BZ consumers) show increase of the CD57 lymphocyte subset as well as natural killer cytotoxicity. Alterations of several biological markers have also been found, specifically in the oral glucose tolerance test, the intramuscular clonidine test, and the supine/orthostasis/exercise test. From a clinical point of view, the three groups appear to be more susceptible to the appearance and progression of many acute and chronic diseases (infectious and malignant diseases). As a result, chronic consumption of BZs should be avoided in both the elderly and subjects in unresolved-stress situations.

We studied the symptom structure of panic attacks in 94 patients attending an outpatient psychiatric clinic. Autonomic symptoms of anxiety were reported by the majority of the panic patients. As compared with studies from the West, certain cognitive symptoms, such as fear of loss of control and depersonalization, and vestibular symptoms were endorsed by fewer panic patients. The majority of our panic patients tended to seek help initially from physicians and medical specialists. The majority of the patients also did not experience some DSM-IV symptoms as part of their panic attacks. Comorbid psychiatric conditions influenced the symptom structure of panic attacks. A higher number of agoraphobics as compared with patients with uncomplicated panic disorders had the symptoms of fear of loss of control and fainting. Our findings support the notion that the experience of panic attacks is variable and differs across cultures.
