The therapeutic benefit of the repetetive transcranial magnetic stimulation on the specific symptoms of schizophrenia Tomas NOVAK Prague Psychiatric Center Summary Transcranial magnetic stimulation is the modern non-invasive method based on the principle of electromagnetic induction. The TMS is widely used in research, diagnostics and treatment of neuropsychiatric disorders. Previous studies imply that repetetive TMS (rTMS) might be useful also in the treatment of some specific symptoms of schizophrenia. The thesis consists of three studies focused on the evaluation of the therapeutic effect of rTMS on specific symptoms of schizophrenia, particularly on negative symptoms and auditory hallucinations. Study 1. The double-blind sham-controlled study of high-frequency rTMS (20Hz) for negative symptoms in schizophrenia The high-frequency repetitive transcranial magnetic stimulation (HF-rTMS) over the prefrontal cortex is a promising method for the treatment of negative symptoms of schizophrenia. Using double-blind, sham- controlled, parallel design, we evaluated the effect of HF-rTMS over the left dorsolateral prefrontal cortex (DLPFC) on negative symptoms in patients with schizophrenia. Sixteen schizophrenia patients with predominantly negative symptoms on stable antipsychotic medication were treated with 20Hz...

Early diagnostic of mnestic disorders in neurodegenerative diseases

The ageing of the world's population means that the number of people with dementia, especially Alzheimer's disease (AD), will dramatically increase. That's why there is now a great effort to detect the presence of AD in its earliest predementia stages, in the stage of mild cognitive impairment (MCI), and particularly to identify individuals with amnestic syndrome of the hippocampal type (Ha-MCI - preclinical AD). The aim of our studies was to reveal whether spatial navigation testing could serve as an early biomarker of AD - whether spatial navigation is impaired early in patients with MCI, especially in Ha-MCI patients. We used the human analogue of the Morris water maze, the Hidden Goal Task (HGT), which is designed t! o separate two different modes of navigation, egocentric (body- centred, hippocampus independent) and allocentric (world-centred, hippocampus dependent), using a real space navigation setting called the Blue Velvet Arena (BVA), fully enclosed cylindrical arena, as well as a computer version of the BVA. Our results suggest that spatial navigation is impaired already in patients with amnestic MCI, who are more likely to progress to AD, especially in those with amnestic syndrome of the hippocampal type. The Ha-MCI patients presented severe spatial navigation impairment similar to that seen in...
