Zusammenfassung
Emotionen rücken, wenngleich schon in früher psychiatrischer Fachliteratur thematisiert,
erst jetzt wieder zunehmend in den Fokus neuropsychiatrischer Forschung. Dies ist
einerseits auf die herausragende Bedeutung für die Symptomatologie psychiatrischer
Erkrankungen, andererseits aber auch auf die technische Weiterentwicklung im Bereich
der funktionellen Bildgebung zurückzuführen. Diese erst ermöglicht die notwendigen
komplexen Untersuchungsparadigmen. Insbesondere schizophrene Patienten zeigen in verschiedenen
Studien zu emotionalen Prozessen Defizite, z. B. bei Paradigmen der Stimmungsinduktion
oder der Emotionsdiskrimination. Diskutiert wird insbesondere, inwiefern emotionale
Dysfunktionen über verschiedene Phasen der Erkrankung, möglicherweise bereits im Prodromalstadium,
nachweisbar sind. Hierfür ist es hilfreich, auch jugendliche Patienten mit ersten
psychosenahen Symptomen zu untersuchen. Für die Zukunft wird es von besonderer Bedeutung
sein, den Einfluss von Emotionen auf kognitive Funktionen bei Gesunden und bei psychiatrischen
Patienten zu untersuchen und differenzielle Unterschiede zu charakterisieren.
Abstract
Emotions have been discussed in earliest psychiatric literature as core characteristics
of psychiatric patients. More recently emotions got back into the focus of modern
neuropsychiatric imaging research. This is due to the outstanding importance of emotions
for psychiatric symptomatology and also to recent technical developments in neuroimaging,
which lay the ground for more complex paradigms. Especially schizophrenic patients
show deficits in emotional functioning, such as in mood induction or emotion discrimination.
It is subject to discussion how stable these dysfunctions are over the course of schizophrenia,
e. g. in prodromal stage. Therefore research also deals with juvenile patients with
schizophrenia-like symptoms. In the future it will be essential to characterize the
effect of emotions on cognitive functions in healthy subjects and psychiatric patients.
