Abstract
Patients with schizophrenia occurs significantly impaired cognition, especially attention, memory, executive functions and speech capabilities. These deficits have often resulted in a decreased in the quality of patients' life.
For this reason, contemporary studies focus on finding other tools that would lead to more effective treatment and eventually have positive influence on treatment of resistant psychotic symptoms. Transcranial direct current stimulation is one of the investigated methods.
During tDCS the brain activity is modulated, which according to the results of some present studies may result in the improvement of cognitive functions (memory, attention, language, executive functions and visual moving). Current research activities verify the possible influence on other symptoms of schizophrenia, such as auditory hallucinations, negative symptoms or catatonia.
Contemporary evidence shows that the transcranial direct current stimulation is a potential augmentation treatment of accompanying symptoms of schizophrenia.
