Susan Collins essential tremor Diagnosis: What It Means for Her Senate Run

Sen. Susan Collins (R-ME) disclosed she has lived with Susan Collins essential tremor throughout her 30‑year Senate tenure, assuring voters the condition does not impair her duties. In a brief interview with News Center Maine she said, “I have had it for the entire time that I have served in the United States Senate. It has absolutely no impact on my ability to do my job or on how I feel each day.”

“The tremor is occasionally inconvenient, and sometimes the subject of cruel comments online, but it does not hinder my ability to work,” Collins told the Associated Press.

Susan Collins essential tremor: medical facts and political fallout

Essential tremor, a neurological movement disorder, triggers rhythmic shaking of the hands, head, voice or limbs during activity. It is ↑ 20x more common than Parkinson’s disease, though it typically progresses slowly at 1%–2% per year. Reuters notes that only about ↓ 10% of sufferers seek medication, usually beta‑blockers or anti‑seizure drugs that dampen nervous‑system activity.

Experts such as Dr. Elan Louis of UT Southwestern explain that the tremor appears when patients use their hands – writing, drinking, typing – and may worsen under stress. While the disorder can modestly raise the chance of developing Parkinson’s to roughly 2%–4%, most patients never experience it.

Impact on daily life and campaign dynamics

For Collins, the tremor has become a talking point in a tightly contested 2026 midterm race, where age and health are already under scrutiny. Her opponent, Democrat Graham Platner, has highlighted his own military‑related injuries, turning health narratives into campaign fodder.

Clinicians stress that treatment options range from medication to surgical interventions such as deep‑brain stimulation or focused ultrasound, which can cut tremor amplitude by up to 90%. Successful procedures often restore confidence and reduce social stigma, a factor many patients cite as the primary driver for seeking care.

While Collins assures constituents the condition is manageable, neurologists warn that untreated tremor can affect fine‑motor professions and erode quality of life. Ongoing research aims to develop targeted therapies, with a promising drug currently under FDA review.
