Essential tremor is a common movement disorder — more common than tremors that come with Parkinson’s disease — and the most common neurologic condition affecting people 65 and older. It is estimated that 10 million Americans live with essential tremor, according to the International Essential Tremor Foundation.
About half of people with essential tremor inherited the condition. But the severity and affected body parts can differ from generation to generation, and researchers still haven’t pinned down the gene or genes responsible.
Tremors typically happen when people try to use their hands for a task. Activities such as shaving can be difficult’ people often need to use safety razors or electric razors to avoid cutting or nicking themselves. Also, difficulty holding a utensil makes eating a challenge for many people with essential tremor.

Dr. Nilüfer Ertekin-Taner, neurogeneticist and behavioral neurologist, discusses characteristics of neurodegenerative diseases such as dementia, Alzheimer’s disease, and movement disorders. She also discusses her research on the complex genetics of Alzheimer’s disease, including identifying therapeutic targets and biomarkers. She highlights Mayo Clinic’s unique approach to patient care.
From a Neuroscience News & Research online article:
“The link between antibiotic exposure and Parkinson’s disease fits the current view that in a significant proportion of patients the pathology of Parkinson’s may originate in the gut, possibly related to microbial changes, years before the onset of typical Parkinson motor symptoms such as slowness, muscle stiffness and shaking of the extremities. It was known that the bacterial composition of the intestine in Parkinson’s patients is abnormal, but the cause is unclear. Our results suggest that some commonly used antibiotics, which are known to strongly influence the gut microbiota, could be a predisposing factor,” says research team leader, neurologist Filip Scheperjans MD, Ph.D. from the Department of Neurology of Helsinki University Hospital.
Higher exposure to commonly used oral antibiotics is linked to an increased risk of Parkinson’s disease according to a recently published study by researchers from the Helsinki University Hospital, Finland.
The strongest associations were found for broad-spectrum antibiotics and those that act against anaerobic bacteria and fungi. The timing of antibiotic exposure also seemed to matter.
The study suggests that excessive use of certain antibiotics can predispose to Parkinson’s disease with a delay of up to 10 to 15 years. This connection may be explained by their disruptive effects on the gut microbial ecosystem.
