Maine Senator Susan Collins announced she has been diagnosed with essential tremor, a neurological condition that causes involuntary shaking movements.

The Republican senator disclosed the diagnosis publicly, stating that the condition has not affected her ability to perform her duties in the Senate. Essential tremor is a common neurological disorder that typically causes rhythmic shaking, most often in the hands, though it can affect other parts of the body.

Collins emphasized that the diagnosis has not impacted her work performance or daily activities. "It has absolutely no impact on my ability to do my job or on how I feel each day," she said in her statement.

Essential tremor affects millions of Americans and is often hereditary. While the condition can worsen over time, many people with essential tremor continue to lead normal, productive lives with proper management.

Collins, who has served in the Senate since 1997, is known for her moderate positions and has been a key swing vote on numerous pieces of legislation. Her disclosure comes as she continues her Senate duties representing Maine.
