Chronic conditions that affect the nervous system, especially the brain, such as Epilepsy, Parkinson’s disease, and Alzheimer’s disease can cause a variety of symptoms, such as impaired mobility, lack of coordination, and strength control that is too strong or inadequately weak, loss of sensory perception, and cognitive decline. Alzheimer’s disease is the most common ailment among these to produce dementia, which impairs cognitive function and independence in day-to-day activities. The study focuses on the relationship between neurodegenerative diseases, risk factors, preventive measures, and the significance of early detection and neurorehabilitation treatments for these ailments. Additionally, it investigates how lifestyle choices can slow down the advancement of neurodegenerative illnesses and can be used as a predictive tool for early identification, especially with Alzheimer’s disease.
