Direct Current Stimulation

Transcranial direct current stimulation (tDCS) continues to demonstrate success as a medical intervention for neurodegenerative diseases, psychological conditions, and traumatic brain injury recovery. One aspect of tDCS still not fully comprehended is the influence of the tDCS electric field on neural functionality. To address this issue, we present a mathematical, multiscale model that couples tDCS administration to neuron electrodynamics. We demonstrate the model’s validity and medical applicability with computational simulations using an idealized two-dimensional domain and then an MRI-derived, three-dimensional human head geometry possessing inhomogeneous and anisotropic tissue conductivities. We exemplify the capabilities of these simulations with real-world tDCS electrode configurations and treatment parameters and compare the model’s predictions to those attained from medical research studies. The model is implemented using efficient numerical strategies and solution techniques to allow the use of fine computational grids needed by the medical community.

Transkranielle Gleichstromstimulation

Zusammenfassung Gegenstand und Ziel: Die transkranielle Gleichstromstimulation (transcranial direct current stimulation, tDCS) wird als neues nicht invasives Hirnstimulationsverfahren für die Behandlung neurologischer und psychiatrischer Erkrankungen untersucht. Mittlerweile gibt es Fallberichte und eine randomisierte, kontrollierte Pilotstudie zur Behandlung akustischer Halluzinationen sowie der Negativsymptomatik bei Schizophrenie. Fallbericht: Im vorliegenden Fallbericht wurde ein Patient mit therapieresistenter Symptomatik bei paranoider Schizophrenie drei Wochen lang mit anodaler tDCS über dem linken dorsolateralen und kathodaler tDCS über dem rechten dorsolateralen Kortex behandelt. Ergebnisse: Es zeigte sich eine Verbesserung von Affektivität und Kognition, die Positivsymptome blieben jedoch nahezu unverändert. Klinische Relevanz: Die bifrontale tDCS stellt eine nebenwirkungsarme neue Behandlungsform dar und sollte in der Anwendung bei Erkrankungen aus dem schizophrenen Formenkreis weiter untersucht werden.
