Sen. Susan Collins of Maine says she has long had a benign neurological condition—described as an essential tremor—that sometimes causes visible shaking in her hands, and at times affects her head or voice. The disclosure comes after public scrutiny and online debate prompted by recent video appearances and campaign-related footage in her reelection campaign. Collins, 73, told local and national outlets that she has lived with the condition for decades and that it is “extremely common.” Multiple reports state that she is taking medication for the tremor and that she believes it has no impact on her ability to do her job or on how she feels day to day. While some outlets use the phrase “essential tremor,” others describe it as “benign tremor” or “benign essential tremor,” referring to the same condition. Across coverage, Collins emphasizes that the tremor affects her appearance but does not impair her Senate responsibilities amid a competitive campaign.
