Under investigation were 25 men and women at the age of 50 – 70 years with a beginning arteriosclerotic encephalopathy.

The patients were treated with both relaxing and activating Medical Resonance Therapy Music^®.
There were 10 treatments in total, each treat­ment lasting from 10 to 30 minutes. Starting with a habituation phase of 10 minutes the treatment was expanded step by step up to 30 minutes. During the first three treatments relaxing MRT-Music^® was given, in the fol­low­ing four treatments the patients received ac­ti­vat­ing MRT-Music; during the last three treat­ments they received in the first 10 minutes re­lax­ing and in the following 20 minutes ac­ti­vat­ing MRT-Music^®.

During the whole time of treatment with Medi­cal Resonance Therapy Music^® the patients did not receive any medication effecting the central nervous system.


Results

From the third treatment on an average re­duc­tion of 5 heart beats per minute during the relaxing music (±1) and 3,1 beats per minute (±1) during activating music was registered.
