Description
Parkinson's disease is a neurological disorder with cardinal motor signs of resting tremor, bradykinesia and lead-pipe rigidity. In addition, many patients display non-motor symptoms, including a diminished sensation of smell, gastrointestinal problems, various disorders of sleep and some cognitive impairment. These clinical features – particularly the motor signs – manifest after a progressive death of many dopaminergic neurones in the brain. Conventional therapies can reduce the signs of the disease, however, the progression of this neuronal demise has proved difficult to slow or stop, and the condition is relentlessly progressive. Hence, there is a real need to develop a treatment that is neuroprotective and slows the pathology of the disease effectively.
At present, there are several neuroprotective therapies in the experimental pipeline, but these are for the patients of tomorrow. This book focuses on two therapies that are readily available for the patients of today. They involve the use of exercise and light (i.e. photobiomodulation: the use of red to infrared light therapy on body tissues). Given the heterogeneity of Parkinson's disease in humans, tackling the condition from a range of different angles – with several different therapies – would only serve to enhance the positive outcomes. This book considers the use of exercise and light therapies, proposing that they have the potential to make a powerful "dynamic duo", offering a most effective neuroprotective treatment option to patients.
About Editors
John Mitrofanis gained his PhD at The University of Sydney. He is professor of anatomy at Sydney Medical School. Throughout his career he has been an active teacher of topographical anatomy and neuroanatomy to medical and science students, and he has run a research programme on brain organisation. His research has examined the structure and patterns of connectivity in the adult and developing thalamus, cortex and brainstem, and he has explored different methods that improve the function and survival of neurones in Parkinson's disease.
