LIGHT THERAPY TREATMENT FOR DEMENTIA

Abstract

The purpose of this thesis is to analyze the effects of light therapy on symptoms of dementia and to develop best practice recommendations for implementation in the healthcare setting. As dementia is a progressive condition characterized by deterioration of cerebral function and structural changes, the need for alternative therapies for symptom management is imperative. Based on current data, there are 55 million people impacted by dementia worldwide and it accounts for the seventh leading cause of death, as well as a significant cause of disability and dependency (World Health Organization [WHO], 2023). Bright light therapy is a newly studied therapy that is potentially effective in improving symptoms of dementia, including sleep disturbances, behavioral and psychological symptoms, and delirium, however, the extent of the effect on these symptoms is unclear. Implementation of light therapy is an accessible and cost-effective management method to improve symptoms for affected individuals to improve their quality of life. This is a non-invasive method that can be employed in any setting, whether in a clinical or home setting. In the fourth chapter of this thesis, a proposed plan to integrate the therapy in a memory care unit of a long-term care setting is outlined based on best practice recommendations compiled contingent on current evidence-based research.
