In the face of the limitations in pharmacological and surgical interventions for neurological conditions such as Parkinson's and Alzheimer's disease, patients are increasingly turning to non-pharmacological and alternative therapies to manage their symptoms and improve their quality of life. This shift underscores the urgent need for accessible, effective, and affordable treatments. This literature review examines a range of alternative and personalized therapies, including game therapy, animal-assisted therapy, dance therapy, art therapy, music therapy, aroma therapy, and shinrin-yoku therapy. These modalities have demonstrated promising results in mitigating symptoms and enhancing well-being among individuals grappling with neurological disorders. Moreover, these therapies offer a holistic approach that complements traditional medical interventions, underscoring the importance of integrating diverse treatment modalities. Despite their historical roots in non-clinical settings, their potential in modern clinical practice remains untapped. The findings suggest the necessity for further research, particularly large cohort studies, to validate the efficacy of these personalized therapies and advocate for their widespread adoption. In an era marked by escalating healthcare costs, the exploration of alternative therapies presents a compelling avenue for enhancing patient care while simultaneously addressing economic challenges within the healthcare system.
