Parkinson's Disease

Parkinson's Disease Dataset

Introduction:
Parkinson's disease is a progressive neurological disorder that affects movement control. It is one of the most common neurodegenerative diseases worldwide, primarily affecting the elderly population. Early diagnosis and treatment are critical for managing the symptoms and slowing down disease progression. This Parkinson’s dataset, available on Kaggle, provides a rich collection of clinical and acoustic voice measurements to help develop AI models for early detection, progression monitoring, and treatment optimization.

Scientific Overview:
This dataset is an essential resource for researchers and healthcare professionals focusing on neurological disorders, especially Parkinson’s disease. It includes detailed voice recordings and acoustic features that have been linked to Parkinson's disease symptoms. The dataset provides valuable insights for developing machine learning models aimed at early diagnosis, monitoring disease progression, and predicting treatment outcomes.
