OLDER_ADULT
Accepts healthy volunteers: no
Allocation: RANDOMIZED
Intervention model: PARALLEL
Intervention model description: In total, about 50 study participants will be examined in a prodromal or symptomatic early stage of Alzheimer's disease. These should be distributed equally randomized into two groups: a movement group (n = 25) with intensified training (equipment, coordination, balance) and a control group with continuation of physical activity as usual and participation in a psychoeducational program (n = 25).
Primary purpose: BASIC_SCIENCE

Brief summary: This study aims to gain a better understanding of metabolic early changes in neurodegenerative diseases, in order to enable new diagnostic and therapeutic approaches in the future. Further, it aims to identify specific movement-induced changes at the cerebral level, on cognition, on quality of life and physical fitness, and on serology parameters in neurodegenerative diseases.

In general, valid biomarkers are needed for early diagnosis and prediction of disease progression. It has been hypothesized that metabolic changes may precede structural changes and may be examined by intervention with exercise therapy. The non-invasive, in vivo characterization and diagnosis of such metabolic changes is therefore of paramount importance. In this line, this research project is focused on applying magnetic resonance imaging (MRI) based metabolic imaging techniques such as sodium MRI and phosphorus magnetic resonance spectroscopy (MRS) with standard structural and functional MRI methods, combined with exercise training, in order to detect biomarkers early in different stages of neurodegenerative diseases. Moreover, this project aims to examine the sensitivity of metabolic imaging with sodium and phosphorus sequences over classical MRI imaging with whole body fat sequences, in order to detect cerebral alterations.

At the end, the medical benefit of the planned project lies in the fact that the expected findings are groundbreaking for the understanding of the phenomenology and pathobiology of neurodegenerative diseases. This is the basis for the development of new methods for early diagnosis and individualized medicine with the optimization of future treatment options.

* cancer in the last 5 years (except basal cell and spinal cell carcinoma) Contraindications for MRI examination below 3 Tesla (for example, implantation of ferromagnetic parts) For study participants, the following measures must be observed due to the direct effects of the magnetic field, in particular the force exerted on para- or ferromagnetic bodies: Study participants with incorporated metallic implants are not admitted. Pregnancy or lactation, traumatic brain injury, neurological or psychiatric disorders (other than the neurological disease to be studied for patients), relevant and severe other medical conditions, e.g. metabolic, endocrinological or cardiac disorders, mental retardation, magnetic metal implants (also intrauterine spiral).

Furthermore, the spatial conditions in the magnet do not allow to examine persons with certain back complaints or a strong overweight. As a rule, a body mass index (BMI, weight \[kg\] / size2 \[cm2\]) of \> 30 is the exclusion criterion. With regard to the participation in the exercise in advance with unclear suitability is a consultation with the attending family doctor regarding possible contraindications, which are a regular participation in a sports program in the way.

Specifically, as exclusion criteria count:

Diseases:

* epilepsy
* severe cardiac pre-existing conditions
* Musculoskeletal disorders that are contrary to regular exercise
* advanced osteoporosis
* Increased fall risk / imbalance
* Advanced Heart Failure, Shortness of Breath, Severe Pulmonary Disease, which are contrary to regular physical activity
* Diabetes mellitus prone to hypoglycaemia and hyperglycemia

Conditions:

* pregnancy
* Uncertain knowledge about possibly existing pregnancy

Contraceptives:

* Any type of intrauterine device
* Spiral made of copper Metal-containing implants or devices in / on the body (all non-metal implants / devices / patches will undergo a thorough examination based on the MRI Safety

Listing www.mrisafety.com):

* Pacemaker / implanted pacemaker wires
* Implanted defibrillator
* Drug pump / infusion device
* Stimulation device / electrodes

Non-MRI-compatible implants, for example, surgical screws, plates, nails, etc:

* vascular / lumen filters, wire rings, wire spirals, stents, vascular clips
* Artificial heart valve
* Transdermal patches
* epithesis (or partial epithesis)
* shunts, catheters, wire sutures

Metal in / on the body:

* Splinter / gunshot wounds
* Metal shards in the eye, even if everything was supposedly removed
* Piercing

Dental metals:

* Any type of implant in the jawbone area / dental implant older than 20 years
* No contraindications: Amalgam fillings, inlays, crowns, single crowned teeth as a denture base for a denture termed a telescopic denture, firmly screwed dentures

Additional:

* cochlear implant
* Ventilation Tubes
* tattoos / permanent make-up (only after the most exact examination and special approval see separate explanation)
