6 Signs of Essential Tremor Most People Blame on Getting Older

By Mike Harper · November 5, 2026

A cup rattles on the saucer. Handwriting gets smaller and shakier. A nod that looks like a yes or a no shows up when you are not nodding on purpose. Each one is easy to chalk up to age. Together, they can point to essential tremor, one of the most common movement disorders.

The National Institute of Neurological Disorders and Stroke says essential tremor is marked by shaking in both hands and arms during action, without other neurological signs. MedlinePlus, drawing on the same NIH institute, calls essential tremor the most common type of tremor and says it usually affects both hands and arms while you are moving them. Tremor overall is most common in middle-aged and older adults, NINDS says, and essential tremor often first appears in middle age, between ages 40 and 50, though it can start earlier.

A key contrast matters for anyone who has watched a hand shake. Parkinson’s disease tremor is usually a rest tremor, most noticeable when the hands are still, and it often starts on one side. Essential tremor shows up with movement. NINDS says the shaking can be mild and stay mild, or slowly get worse over time. There is no cure for most forms of tremor, but treatments exist to help manage symptoms.

These are six signs drawn from NINDS and MedlinePlus.

Shaking in both hands and arms during action. NINDS says the key feature is tremor in both hands and arms during action. It can show up when you hold a cup, write, eat, shave or button a shirt. MedlinePlus lists problems holding and controlling utensils, such as a spoon, among common symptoms.

A head tremor that looks like a yes-yes or no-no nod. Essential tremor can also affect the head, NINDS says. The head may move in a nodding pattern that looks like yes or no even when you are not answering anyone.

A shaky voice. Both NINDS and MedlinePlus list a shaky voice among the symptoms. The tremor can involve the vocal cords, so speech may sound uneven or quivering.

Shaking that gets worse with stress, tiredness, caffeine or some medicines. NINDS notes that some tremor can be triggered by stress or strong emotion, being physically tired, or by caffeine, and that several medicines can cause or worsen tremors. MedlinePlus adds that too much caffeine can trigger tremors and that cutting stimulants from the diet may help if they set yours off.

Trouble with fine tasks. NINDS says tremor can make writing, typing, eating, shaving and dressing more difficult. Difficulty writing or drawing is on the MedlinePlus symptom list as well. Holding a full cup or signing a form can become a daily struggle.

It runs in families. NINDS says essential tremor is an inherited condition in 50 to 70% of cases, often called familial tremor, and that familial forms often appear early in life. MedlinePlus notes that for certain types of tremor, a family history raises the risk.

If a new tremor shows up, or an old one gets worse, see a doctor. NINDS says a clinician will check whether the tremor happens at rest or in action, where it sits on the body, and how it looks. Blood or urine tests and imaging may rule out other causes. Medicines such as certain beta blockers or anti-seizure drugs help some people, and surgery options exist when tremor severely affects daily life. Do not stop or start a medicine on your own.
