A recent experimental study suggests that song therapy can reduce some of the serious Parkinson's disease and mood disorders, a neurological condition that affects more than 10 million people worldwide, often affecting the elderly.
Parkinson's disease may occur, mood changes with heart attacks and depression are relatively common. Drugs can help reduce symptoms, but they tend to become less effective as the disease progresses and may have worse side effects.
Researchers at the University of Iowa recently conducted a pilot study to monitor the effect of the song on a small group of patients with Parkinson's disease. The team of researchers was head of Dr. Elizabeth Stigmoller, assistant professor of motion science at the University of Iowa, where the benefits of the song were studied for the treatment of patients with Parkinson's disease.
It has also been shown that the song can function well as part of speech therapy as well as improve the patient's ability to swallow because the song requires more rigorous control of the muscles in the mouth and throat.
The survey focused on the group of therapeutic songs, consisting of 17 individuals who watched an average of 2.4 years. The researchers measured heart rate, blood pressure and cortisol levels before and after the session. Participants also completed a questionnaire evaluating levels of anxiety, sadness, anger, and happiness.
Although cardiac rhythms, blood pressure and cortisol levels fell into the plaque – in this small sample – the changes were not significant and there was a remarkable decrease in the levels of anxiety and sadness after the sessions.
Patients had improved every week and began to work on light activity and simple steps, to feel the gradual improvement in their mood.
