Which symptom is least likely associated with Wilson's disease?

Wilson's disease is a genetic disorder that leads to the accumulation of copper in the body, particularly affecting the liver and brain, which can result in a variety of symptoms. Among the options listed, intention tremor is the symptom least likely associated with Wilson's disease.

Dementia is a potential neurological manifestation of Wilson’s disease due to the copper deposition in the brain, particularly in parts that regulate cognition and behavior. Patients may experience personality changes, cognitive decline, and other psychiatric symptoms.

Kayser-Fleischer rings are a classic finding in Wilson's disease and appear as brownish or golden rings around the cornea due to copper deposition. The presence of these rings is often used as a diagnostic indicator.

Chronic hepatic dysfunction can occur in Wilson's disease as liver cells become damaged from excessive copper accumulation. Patients may develop hepatitis, cirrhosis, and other liver-related complications from the disorder.

Intention tremor, while it is a movement abnormality, is more commonly associated with other conditions such as multiple sclerosis or essential tremor. In Wilson's disease, tremors are typically described as resting tremors or postural tremors rather than intention tremors. Therefore, intention tremor is the least likely symptom to be associated with Wilson
