Neurodegenerative disease is a medical condition that affects the nervous system and causes the loss of neurons. Antonyms of neurodegenerative disease include well-being, health, and vitality. While neurodegenerative diseases cause the slow deterioration of brain function, these antonyms represent the opposite, where there is an abundance of energy, mental clarity, and overall physical and mental well-being. Neurodegenerative diseases can result in cognitive decline, memory loss, and movement disorders. In contrast, optimal health and vitality imply a state of mind and body that is free from disease and functional impairment. Thus, it is essential to maintain and enhance our mental and physical well-being through regular exercise, proper nutrition, and healthy lifestyle choices.
