The neuropsychology section specializes in the diagnosis of the consequences of acquired brain injuries, including deficits in memory, attention, visual perception, and the planning and organization of actions. These deficits often occur after brain damage due to stroke, injuries, tumors, and inflammatory and other neurological diseases. They also occur in the cases of progressive diseases like dementia or Parkinson’s disease.
We diagnose patients who exhibit cognitive deficits either as inpatients or during special office hours, such as memory or Parkinson’s disease consultations. We focus on the differential diagnosis of dementias, the classification of mild cognitive impairments and depression, and monitor the severity and progression of these conditions. An additional focus is the pre- and post-surgical neuropsychological testing of patients who are being treated with deep brain stimulation.
The Services of the Neuropsychology Section at a Glance:
- Differential diagnosis of the dementias
- Preparation of expert neuropsychological evaluations for insurance carriers, courts and insurance compensation
- Neuropsychological diagnoses and therapy planning
- Identification of therapy requirements
- Expert evaluations and diagnoses regarding limitations for the warranty of fitness to drive a car
- Professional neuropsychological training (we are an accredited institution for advanced training in clinical neuropsychology)
The neuropsychology section investigates neurophysiological processes using noninvasive methods (e.g., transcranial direct current stimulation [tDCS], transcranial alternating current stimulation [tACS]) and invasive methods (deep brain stimulation [DBS]). We also participate in several research projects conducted by the university clinic as well as multicenter pharmaceutical studies.
In the DFG-funded project (SFB-779) “Valence, Exploration and Action Selection: Role of the STN,” we investigate the consequences of using high frequency deep brain stimulation to inactivate the subthalamic nucleus (STN). In particular, we are investigating how this deactivation effects the manner in which actions are selected as a function of outcome valence, and the attendant impact on the flexibility of instrumental behavior. The research is motivated both by current neurobiological models and preliminary studies we have conducted which suggest that the STN is critically involved in action selection and the coding of the value of rewards. This would make the STN potentially important for controlling the flexibility of instrumental behaviors by regulating interactions between dopaminergic midbrain structures and the striatum.
In the DFG-funded project (SFB-TRR31) “Neural mechanisms of top-down modulation of auditory brain activity in humans,” we use transcranial electric stimulation (tDCS and tACS) to investigate how auditory temporal resolution is related to underlying neural oscillations. This project explores the possibility that electrical stimulation can be used to generate improvements in perceptual processes.
Because tDCS can affect the excitability of the cortex with consequent modifications of cognition and perception, it could potentially serve as a tool for the treatment of various neurological and psychiatric disorders. In an additional project we aim to directly modulate auditory cognition by means of TES. Specifically we are investigating the effects of tDCS over the human auditory cortex on auditory working memory and audio-visual integration.
Further current research is concerned with the systematic investigation of cognitive deficits in chronic traumatic encephalopathy and Alzheimer’s disease, as well as the evaluation of the eﬀect of cognitive and motor training programs in patients with mild cognitive impairment.
