Parkinson's Disease is a progressive neurological disorder that primarily affects movement. It occurs when nerve cells in the brain, particularly those responsible for producing dopamine, become impaired or die. Dopamine is a neurotransmitter crucial for coordinating movement, so its deficiency leads to symptoms such as tremors, rigidity, slowness of movement, and difficulty with balance and coordination. Both genetic and environmental factors are believed to play a role in the development of Parkinson's Disease. The disease usually manifests in older adults, but it can also affect younger individuals. Currently, there is no cure for Parkinson's Disease, but treatment options aim to manage symptoms and improve quality of life. These include medication to increase dopamine levels, physical therapy to enhance mobility and balance, and sometimes surgical interventions like deep brain stimulation. This book unravels the recent studies in the field of Parkinson's Disease. It will also provide interesting topics for research which interested readers can take up. This book will prove to be immensely beneficial to students and researchers in this field.
