Abstract
Motor fluctuations and dyskinesia in later stages of Parkinson's disease (PD) are caused by pharmacokinetic as well as pharmacodynamic factors, intermittent dopaminergic stimulation being one of the most important. In the healthy brain, dopamine neurons in the substantia nigra pars c...

Abstract
In Germany about 300,000 to 400,000 people are suffering from Morbus Parkinson at present. It is one of the most common neurological diseases both in Germany and in Europe as a whole. With the rising number of elderly people in our population, the number of Parkinson patients will strongly increase...

Abstract
We tested whether such spontaneous fear-like behaviour could be observed in an open-field test 12 h after dlPAG stimulation. Further, we tested whether this fear-like behaviour could be attenuated by acute or chronic administration of buspirone and escitalopram. Our data demonstrate for the first ti...

Abstract
Movement disorders, especially dystonia, are a frequent manifestation of neurometabolic diseases. Proper characterization and classification of movement disorders is crucial but may be challenging in this setting. The diagnostic work-up should be focused first on treatable disease. Mixed movement dis...

Abstract
We hypothesized that OCD patients will select a combination of medication and psychotherapy as their most preferred choice overall.
The authors designed a treatment-preference survey using 2 health economics methods, forced-choice and contingent-ranking methods, to elicit preferences for OCD treatme...

Abstract
Preoperatively, the patients used 12.05 +/- 4.57 tablets a day out of 3.19 +/- 0.97 different antiparkinsonian drugs, which was significantly reduced by deep brain stimulation to the application of 7.00 +/- 2.96 tablets out of 1-3 (1.84 +/- 0.76) drugs (p < 0.001). Meanwhile, the usage of amantadine...

Abstract
The aim of this paper is to discuss the restriction of electroconvulsive therapy (ECT) to the treatment of psychiatric disorders and the prohibition of psychosurgery and deep brain stimulation (DBS) in the NSW Mental Health Act 2007 (MHA), and to examine these restrictions from clinical and human ri...

Abstract
We use a modeling approach which is utilized to study the influence of deep brain stimulation on the restoration of segregated activity in the target structures. Besides the spontaneous activity of the target network, the model considers a weak sensory input mimicking signal processing tasks, electr...

Abstract
We studied the effect of low-frequency stimulation (LFS, 1 Hz) or high-frequency stimulation (HFS, 100 Hz) in the MD on amygdaloid kindling seizures. During the kindling acquisition, DBS in the MD was daily administered immediately after the kindling stimulus or before the kindling stimulus (preempt...

In the advanced stages of Parkinson's disease (PD), the conventional orally-administered pharmacological treatment can prove to be insufficient to control the motor complications associated with the disease. One of the causes involved in the genesis of the motor fluctuations that are observed in PD...

The mechanisms underlying pathogenesis of epileptic rections have been studied insufficiently as yet. Therefore, it is considered that determining the structures, transmitters, and receptors of the brain, which putatively produce development and intensity modulation of the convulsions, is highly impo...

Dystonia is not uncommon in childhood, but is clinically very heterogeneous. Therefore, introduction and follow-up of the treatment of dystonia in children are often a challenge for the physicians. Progresses in functional neurosurgery have open new fields in the treatment of dystonia in children, b...

Abstract
The present study suggests a negative effect of the IL1B gene on pharmacological response and amygdala and ACC function involving the same genotypes of two SNPs (rs16944, rs116343), which taken together increase the risk of nonremission over 6 weeks of antidepressant treatment in MDD.
