Shaking palsies, also known as essential tremors, is a condition that affects the nervous system and causes involuntary shaking in body parts such as hands, arms, head, and voice. There are several synonyms that describe this condition, including benign essential tremor, familial tremor, and senile tremor. Other terms that are commonly used include nervous tremors, essential shaking, and quivering limbs. Although shaking palsies are not life-threatening, they can severely impact an individual's quality of life, making everyday tasks such as writing, eating, and even speaking difficult. Treatment options include medication, therapy, and in severe cases, surgery.
