Tremor, also commonly known as 'shaking disease', is a neurological disorder affecting the nervous system. This condition causes involuntary and uncontrollable rhythmic shaking or trembling movements, typically in the hands, but also in the arms, legs, head, and vocal cords. While tremor does not directly threaten life, it can significantly impact individuals' quality of life and severely complicate daily activities. It can lead to disability by creating difficulties in performing essential daily tasks such as writing, eating, shaving, and dressing.
