Blood, cerebrospinal fluid analysis and skin biopsy

Biomaterial is extracted, analyzed and stored to determine different risk markers for neurodegenerative diseases. Combining the results of biomaterial and clinical examinations should help to characterize neurodegenerative diseases in order to be able to detect diseases as early as possible and to classify them better.

Electroencephalography (EEG)

Electroencephalography is used to record electrical signals that are generated naturally during brain activity by means of surface electrodes on the scalp with a high temporal resolution. The examination is safe, painless and can be repeated as often as required.

Magnetic Resonance Imaging (MRI)

Magnetic resonance imaging (MRI, also known as magnetic resonance tomography) enables high-resolution imaging of brain structures (structural MRI) and the display of changes in brain activation (functional MRI, fMRI) using magnetic fields.

At the Institute and Polyclinic for Radiological Diagnostics and at the Heart Center Dresden, devices are available for MRI imaging for DZNE studies.

Neuropsychological Assessment

The aim of a neuropsychological assessment is to identify potential limitations of mental functions. For this purpose, special standardized tests are used. In addition, self-reports by probands, third-party reports by relatives and behavioral observations are also included.  This enables various aspects of performance such as perception, attention, memory and speech, but also emotional experience, personality and everyday behaviour to be recorded and assessed with regard to possible disease-related changes.

Oculography - Recording of eye movements (eye tracking)

The use of an eye tracker in clinical studies makes it possible to investigate the relationship between eye movement disorders and cognitive and motor changes in the context of neurodegenerative diseases.

The eye movement is recorded by a camera using a weak infrared light beam and is neither unpleasant nor harmful to the eyes.

Optical coherence tomography (OCT)

Optical coherence tomography (OCT) allows an exact representation of the ocular fundus (including papilla, macula and choroid). With the help of harmless laser light, an image-layer image of the retina can be taken in a short time without exposure to radiation or contact with the eye.


Polysomnography is an instrumental procedure for the examination of sleep. Using sensors and surface electrodes, numerous biological parameters are recorded to detect changes in sleep architecture and brain electrical activity during sleep, as well as specific sleep disorders in the context of neurodegenerative diseases.

Quantitative motor methods / actigraphy / gait analysis

By means of special equipment, motor anomalies can be objectively measured. The use of these quantitative techniques makes it possible to detect disorders much earlier and to objectively identify the effects of new therapies.

Ultrasound examination (Sonography)

This is a side-effect-free imaging examination without radiation exposure, which can be used to visualize changes in the vascular walls (e. g. brain-supplying vessels in the cervical region or in the head), changes in brain tissue (e. g. changes in the signaling behaviour of the substantia nigra in Parkinson's disease) and changes in peripheral nerves.
