Dementing syndromes are, for the most part, incurable. People with dementia become highly dependent and frequently have to move from their homes into residential aged care facilities.

Medications aimed at reducing the severity of a number of symptoms associated with the different types of dementia have had only modest success.

Increasingly, people with dementia, their families and carers are turning to supplementary or alternative approaches to the management of their symptoms. There are many published reports describing the successful use of music therapy in reducing the severity of many symptoms of dementia. These include reports of improved memory, improved language skills, reduced anxiety and depression, reductions in agitation and disruptive behaviours and better social relationships with family, peers and carers. However, the quality of evidence they provide for the most part fails meet the standards of evidence required by health care providers. This clinical trial will examine the effects of a music therapy intervention.

The study will recruit 180 patients in sub-acute hospital wards. Participants will be randomly placed in groups that receive either occupational therapy or music therapy. Before the therapy programs begin, we will use questionnaires to measure memory function, language ability, orientation and mood. We will also record brain activity from the surface of the scalp, blood pressure and pulse to examine physiological responses. The same measures will be repeated after the 3 weeks of therapy to determine whether there has been any improvement in the symptoms of the participants and whether the group that had music therapy showed greater improvement than the group that had occupational therapy. We will make a video recording during one therapy session to allow us to observe levels of engagement and to assess changes in facial expressions. This will provide information about the immediate effects of music on mood and social interaction. The information we collect about brain activity and blood pressure will help us to understand how music therapy might bring about changes in the symptoms of dementia. This understanding will be useful in developing better applications of music therapy. It will also add to our current knowledge about how the various diseases cause the problems they do.

In summary, the primary aim of the project is to determine whether the reported effects of music therapy are supported by objective evidence.
