Psychosis terms a serious mental disorder that is accompanied by a temporarily extensive loss of contact with reality.

The term was used first from Ernst von Feuchtersleben in 1845. The word ‚psychosis’ came into the German language similar to French technical terms with French endings from the Greek ψύχωσις, psýchōsis, originally „inspiration“, von ψυχή, psyché, „soul“, „spirit“ and the ending -οσις, -osis, „[pathological] condition“ – ancient Greek pronunciation.

The term generally is used in differentiation to the expression ‚neurosis’ in fact for psychical disorders which are serious and cannot or solely not be influenced by psychotherapy and which can readily be deduced from the context of the life history.

The rTMS helps psychotics to improve their motivation („negative symptomatology“) and to reduce hallucinations („positive symptomatology“).

Current rTMS studies concerning schizophrenia:

• Working memory and DLPFC inefficiency in schizophrenia: the FBIRN study
• Treatment of negative symptoms of schizophrenia using repetitive transcranial magnetic stimulation in a double-blind, randomized controlled study
• Transcranial magnetic stimulation for auditory hallucination in severe schizophrenia: Partial efficiacy and acute elevation of sympathetic modulation
• Effects of 10 Hz repetitive transcranial magnetic stimulation (rTMS) on clinical global impresion in chronic schizophrenia
• Two-day treatment of auditory hallucinations by high frequency rTMS guided by cerebral imaging: a 6 month follow-up pilot study
• High-frequency prefrontal repetitive transcranial magnetic stimulation for the negative symptoms of schizophrenia: a case series
