26 patients with psychovegetative disorders of neurotic origin (vegetative dystonia syndrome, hyperventilation syndrome, panic attacks, headache, insomnia, motivation disorders) were treated. Light therapy (LT) was carried out every day during 2 weeks. The light of 4500-5000 lux was applied during 1 hour (the distance-60 cm). As a result positive effect was revealed in 11 patients while there was no effect in 15 individuals. The positive effect was observed as a decrease of clinical manifestations. Patients with positive treatment results were characterised by short disease duration, weak hypothalamus dysfunction, astheno-depressive disorders prevalence. Negative effect of LT was observed in patients with longer duration of disease, more severe hypothalamic dysfunction together with anxious and astheno-hypochondriac syndrome. The conclusion a made that LT effect is associated with the character and the degree of psychovegetative disorders, but not with presence or absence of hypothalamic dysfunction.

Peculiarities of paroxysmal course of autonomic dystonia of cardiac type were studied in 148 juveniles aged 14-15 years. It was found that frequency of panic attacks was very high, i.e. they occurred in 67-92.4% of the cases in dependence on severity of the disease. Panic attacks had no definite clinical picture at the onset. However, as the intensity of the main clinical manifestation of the disease (chest-pain syndrome) increased they acquired clear-cut sympatho-adrenal or vago-insular direction. Short duration and incomplete nels are typical for panic attacks in these patients.

This paper attempts to elucidate whether common (nonspecific) brain mechanisms are responsible for seizures of epileptic and nonepileptic origin. A comparative study of the following 4 paroxysmal disorders--partial epileptic seizures, paroxysmal dystonia, pseudoseizures and panic attacks was performed. Spontaneous (EEG-mapping) and evoked (contingent negative variation-CNV) bioelectrical activity was measures in all patients several times during interictal periods and after 24-hour sleep deprivation. The main common neurophysiological features of these types of paroxysmal disorders were the increased total power of spontaneous electrical activity, an asymmetric increase of theta-EEC power in the right hemisphere, an increase in total amplitude of CNV. Readiness of the brain for the development of the paroxysms was characterized by dynamic increases of the above parameters of spontaneous and evoked bioelectrical activity.

Paroxysmal disorders are conventionally divided into paroxysms of epileptic and nonepileptic origin. In spite of the different mechanisms of their development, paroxysmal states of different types have some similar clinical features: short duration of the disorders, frequent combination of emotional, motor and autonomic disorders during paroxysm, normal neurologic status between the attacks, possible positive reaction to anticoagulants. These facts allow to consider a "paroxysm" as a possible universal pathogenetic mechanism of brain's reaction to endogenic and exogenic stimulus. A comparative study of 4 types of paroxysmal states was performed: partial epileptic fits, attacks of paroxysmal dystonia, pseudofits, panic attacks. The elevation of general power of spontaneous electric activity, an interhemispheric assymmetry of the power of theta-range, the reaction of hypersynchronization as the reply to 24-hours of sleep deprivation, the increase of the total amplitude of contingent negative deviation were general neurophysiologic characteristics of the states. "Readiness" of brain to the development of paroxysm was characterised by the dynamic elevation of the indices of spontaneous and evoked biologic activity mentioned above.

The paper presents an open noncomparative investigation of 36 patients with different manifestations of the syndrome of autonomic dystonia. 20 patients (group 1) had permanent autonomic disorder in context of generalyzed anxious disorders, 16 patients (group 2) had panic attacks. The examination was performed before and 4 weeks after monotherapy with xanax (1.5-2.5 mg/day). Clinical-neurologic study estimated both presence and a degree of manifestations of the syndrome of autonomic dysfunction, hyperventilatory syndrome and sleep disorders. Psychologic investigation included estimation of anxiety according to Spilberg's test, depression according to Beck's scale; SCL Scale was also used. Algesic syndrome was estimated by complex algesic questionnaire. Neurophysiologic study determined a contingent negative deviation and nociceptive flexory reflex. A positive therapeutic activity of xanax was established. The highest therapeutic effect was achieved in group 1 (83%) using lower doses (1.5 mg/day). In group 2 higher doses were needed (2.5 mg/day). In this case the effect was achieved in 83% of the cases, but full absence of panic attacks was observed only in 25% of the patients. Predictors of the drug's efficiency appeared to be short duration of the disease, slight manifestation of depression and absence of the algesic syndrome.

We report a case of autosomal dominantly inherited dystonia and panic attacks to discuss successful treatment of a common serotonergic pathology with medication. The objective analysis of the movement disorder was done by Optotrak. First we demonstrate a reduction of the myoclonus by L-5-hydroxytryptophan, which inhibits after 11 months. After changing the medication to Nefadozone, the myoclonus and the frequency of panic attacks were reduced.

The dystonias are a common clinically and genetically heterogeneous group of movement disorders. More than ten loci for inherited forms of dystonia have been mapped, but only three mutated genes have been identified so far. These are DYT1, encoding torsin A and mutant in the early-onset generalized form, GCH1 (formerly known as DYT5), encoding GTP-cyclohydrolase I and mutant in dominant dopa-responsive dystonia, and TH, encoding tyrosine hydroxylase and mutant in the recessive form of the disease. Myoclonus-dystonia syndrome (MDS; DYT11) is an autosomal dominant disorder characterized by bilateral, alcohol-sensitive myoclonic jerks involving mainly the arms and axial muscles. Dystonia, usually torticollis and/or writer's cramp, occurs in most but not all affected patients and may occasionally be the only symptom of the disease. In addition, patients often show prominent psychiatric abnormalities, including panic attacks and obsessive-compulsive behavior. In most MDS families, the disease is linked to a locus on chromosome 7q21 (refs. 11-13). Using a positional cloning approach, we have identified five different heterozygous loss-of-function mutations in the gene for epsilon-sarcoglycan (SGCE), which we mapped to a refined critical region of about 3.2 Mb. SGCE is expressed in all brain regions examined. Pedigree analysis shows a marked difference in penetrance depending on the parental origin of the disease allele. This is indicative of a maternal imprinting mechanism, which has been demonstrated in the mouse epsilon-sarcoglycan gene.

Nocturnal disturbances are common in Parkinson's disease (PD) patients, with almost 70% of these patients reporting nocturnal disturbances. The etiology of sleep disturbances in patients with PD is still controversial. They might be dependent on dopaminergic drugs, on disease progression, or on a combination of these two factors. Nocturnal disturbances can be categorized in four groups: 1) PD-related motor symptoms, including nocturnal akinesia, early-morning dystonia, painful cramps, tremor, and difficulty turning in bed; 2) treatment-related nocturnal disturbances; 3) psychiatric symptoms, including hallucinations, vivid dreams, depression, dementia, insomnia, psychosis, and panic attacks; 4) other sleep disorders, including insomnia, REM behavioral disorder (RBD), restless legs syndrome (RLS), periodic leg movements (PLMS), and excessive daytime sleepiness (EDS). Specific treatment options are supplied for every group. A global evaluation of nocturnal disturbances would provide clinicians with a valuable tool to establish an optimal regimen that could positively influence all nocturnal disturbance categories and thus improve PD management on. However, it is important to consider that management of some nocturnal disturbances in a group may worsen nocturnal symptoms of another group or may increase EDS. PD-related symptoms can be treated with long-acting DA agonists to obtain continuous DA receptor stimulation during the night. Both treatment-related nocturnal disturbances and psychiatric symptoms may be related to drug treatment, and therefore, in both cases, drug reduction or discontinuance should be considered. Some sleep disorders, such as RLS and PLMS, may be controlled by DA agents, and others, such as insomnia and EDS, may be improved by reducing dopaminergic stimulation.

Parkinson's disease is associated with classical Parkinsonian features that respond to dopaminergic therapy. Neuropsychiatric sequelae include dementia, major depression, dysthymia, anxiety disorders, sleep disorders, and sexual disorders. Panic attacks are particularly common. With treatment, visual hallucinations, paranoid delusions, mania, or delirium may evolve. Psychosis is a key factor in nursing home placement, and depression is the most significant predictor of quality of life. Clozapine may be the safest treatment for psychotic features, but more research is needed to establish the efficacy of antidepressant treatments. Dementia with Lewy bodies, the second most common dementia in the elderly, may present in association with systematized delusions, depression, or RBD. Early evidence suggests the utility of rivastigmine, donepezil, low-dose olanzapine, and quetiapine in treating DLB. Parkinson-plus syndromes generally lack a good response to dopaminergic treatment and evidence additional features, including dysautonomia, cerebellar and pontine features, eye signs, and other movement disorders. MSA is associated with dysautonomia and RBD. SND (MSA-P) is associated with frontal cognitive impairments, but dementia, psychosis, and mood disorders have not been strikingly apparent unless additional pathological findings are present. In SDS (MSA-A), impotence is almost ubiquitous; urinary incontinence is frequent; depression is occasional, and sleep apnea should be treated to avoid sudden death during sleep. OPCA neuropsychiatric correlates await further definition. Progressive supranuclear palsy neuropsychiatric features include apathy, subcortical dementia, pathological emotionality, mild depression and anxiety, and lack of appreciable response to donepezil. CBD usually is recognized by early frontal dementia with ideomotor apraxia, often in the right upper extremity, attended later by poorly responsive unilateral Parkinsonism, with additional signs including cortical reflex myoclonus, limb dystonia, alien limb, oculomotor apraxia when asked to look horizontally, depression, personality changes, and, occasionally, Kluver-Bucy syndrome. The neuropsychiatry of FTDP-17 involves apraxia, executive impairment, personality changes, hyperorality, and occasional psychosis. Future research in these Parkinsonian disorders should target the characterization of neuropsychiatric sequelae and their treatment.

We studied 109 consecutive patients who were unselected for freezing of gait (FOG), anxiety, depression, or panic attacks. All patients completed a panic assessment, the Hamilton Anxiety Scale and the Hamilton Depression Scale. Patients were divided into those with FOG or no FOG based on their answer to the FOG question on the Activities of Daily Living part of the UPDRS. Patients with FOG were more disabled, had more "wearing off", dyskinesia, leg dystonia, and postural instability. They were also more anxious and more likely to panic. FOG, in many patients, is increased by anxiety and panic.
