Can Neuropathy Cause Tremors? The Connection Explained

Neuropathy can cause tremors, and it does so more often than most people realize. In one study that combined clinical examination with objective measurement, roughly three out of four patients with various polyneuropathies had detectable tremor, compared to about one in eight people without neuropathy. The connection between nerve damage and shaking is well established in neurology, though it remains underappreciated by the general public and sometimes even by the clinicians treating the neuropathy itself. The reasons it happens, the types of neuropathy most likely to trigger it, and what can be done about it are all worth understanding if you or someone you know is dealing with both conditions at once.

How Common Tremors Are in Neuropathy

The numbers are surprisingly high. A study that evaluated patients with polyneuropathies of various origins found tremor in about 60% on standard clinical examination and in 74% when measured with objective recording devices. Among healthy controls, only 12% had any measurable tremor. Most of the tremors were mild, which helps explain why they go unnoticed or unreported by many patients, but they were clearly present and far more frequent than in the general population.¹

Among inflammatory neuropathies specifically, estimates of tremor prevalence range from about 40% to 70%.² The spread in those numbers reflects differences in how tremor is measured, which patient populations are studied, and whether researchers rely on patients reporting the symptom versus detecting it with instruments. But even the low end of that range means a substantial portion of people with these neuropathies will develop some degree of shaking.

One reason tremors in neuropathy get overlooked is that the neuropathy symptoms people expect, numbness, tingling, burning pain, and weakness, dominate the clinical picture. A subtle hand tremor can seem minor compared to feet that feel like they are on fire. Patients may not even mention it to their doctor, or may assume it is a separate, unrelated problem. Clinicians who are focused on nerve conduction studies and pain management may not ask about it. The tremor is there, though, and in a meaningful fraction of patients it is significant enough to interfere with daily tasks.

Which Types of Neuropathy Are Most Likely to Cause Tremors

Not all neuropathies carry the same tremor risk. Certain forms of peripheral neuropathy have a notably stronger association with tremor than others. The types most commonly linked to tremor include IgM paraproteinemic neuropathy, chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), multifocal motor neuropathy with conduction block, and Charcot-Marie-Tooth (CMT) disease.²

CIDP deserves special mention because the tremor it causes can be particularly stubborn. In one study of 24 CIDP patients, about two-thirds had a postural tremor that looked much like essential tremor.² The tremor often persists even after the underlying neuropathy is treated and nerve function improves, which can be deeply frustrating for patients who thought getting the inflammation under control would resolve all their symptoms.³

Charcot-Marie-Tooth disease, the most common inherited neuropathy, also has a well-documented relationship with tremor. In one study of CMT type 1A patients, postural and kinetic tremors in the hands were evident in about 65%, and lower limb tremors appeared in roughly 35%.⁴ A separate study using different methods found a lower prevalence of around 21%, but among those who did have tremor, nearly half reported that it impaired their ability to function normally.⁵ The combination of CMT neuropathy with prominent hand tremor and gait instability is sometimes called Roussy-Lévy syndrome, a clinical pattern that has been recognized for over a century.⁶

What about diabetic neuropathy, the most common form overall? The relationship is less clear-cut. The broad study that found tremor across polyneuropathies of different origins detected it in all the types examined except IgM paraproteinemic polyneuropathy, suggesting that even more garden-variety neuropathies can be associated with tremor.¹ However, the strongest and most consistent evidence links tremor to the inflammatory and hereditary neuropathies rather than to the metabolic or toxic varieties.

How Damaged Nerves Can Produce Tremors

The mechanism behind neuropathic tremor is not as straightforward as “damaged nerves shake.” The prevailing theory centers on what happens when faulty sensory nerves send garbled information back to the brain. Your nervous system relies on a constant stream of feedback from sensory nerves in your muscles and joints to coordinate smooth movement. When neuropathy degrades those signals, the brain’s motor control centers, particularly the loop connecting the cerebellum, thalamus, and motor cortex, start working with bad data. The result is mistimed or erratic motor commands that manifest as tremor.⁷

This is an important distinction. The tremor originates in the central nervous system, not in the peripheral nerves themselves. The peripheral nerve damage is the trigger, but the shaking is generated by brain circuits that have been thrown off by the corrupted sensory input. Researchers confirmed this directly by recording brain activity during surgery in a patient with neuropathic tremor and found rhythmic oscillations in the thalamus that were driving the tremor, essentially proving that central brain structures are the generators of the shaking even when the root cause is peripheral nerve disease.⁷

Damage to large myelinated sensory nerve fibers, which carry proprioceptive information about limb position and movement, appears to be the most relevant type of nerve injury here. When these fibers deteriorate, the brain loses accurate information about where your limbs are in space and how they are moving.⁸ The motor system tries to compensate, and tremor is one visible consequence of that compensatory effort going awry. Interestingly, research in CMT patients found no evidence that the cerebellum itself is malfunctioning; standard tests of cerebellar function showed no difference between patients with tremor and those without.⁵ The cerebellum seems to be working normally but receiving bad input, like a perfectly functional GPS unit being fed wrong satellite data.

One counterintuitive finding is that the severity of nerve conduction abnormalities does not reliably predict whether someone will develop tremor or how bad it will be. In the multi-origin neuropathy study, the occurrence of hand tremor was not related to whether the neuropathy was primarily axonal or demyelinating, nor to nerve conduction velocity or other electrophysiological measurements.¹ That means you cannot look at a nerve conduction study and predict who will shake and who will not. Something about how the brain adapts (or fails to adapt) to the nerve damage varies between individuals, and that adaptation process is not well understood.

What Neuropathic Tremor Looks Like

Neuropathic tremor most often shows up as a postural tremor, meaning it appears when you hold your hands out in front of you or maintain any position against gravity. In the broad neuropathy study, about 70% of tremors were postural. But roughly half of patients also had a resting tremor, and about a third had a kinetic tremor that appeared during purposeful movement like reaching for an object.¹ Many patients had more than one type simultaneously.

In most cases, the tremor is mild. It may be visible to others or detectable on careful exam, but it does not necessarily dominate the clinical picture the way the cardinal tremor of Parkinson’s disease does. That said, when it is moderate or severe, the functional impact can be significant. Writing, eating with utensils, pouring a drink, buttoning a shirt, and using a phone all become harder when your hands shake. For people with CMT who also have distal muscle weakness in their hands, even a mild tremor on top of the weakness can push manual tasks from difficult to impossible.

The tremor typically has a frequency in the range of about 6 to 9 Hz in the upper limbs, with lower frequencies at the hand and higher frequencies closer to the shoulder.⁴ That is similar to the frequency range of essential tremor, which is one reason the two can look alike at the bedside. Lower limb tremor, when present, tends to be slower, around 5 to 6 Hz, and can impair standing balance, a meaningful safety concern for people who already have weakened ankles and feet from their neuropathy.⁴

Telling Neuropathic Tremor Apart from Other Tremors

This is where things get tricky for clinicians. The most common diagnostic confusion is between neuropathic tremor and essential tremor, because both are predominantly postural, affect the hands, and occur in a similar frequency range. In the broad neuropathy study, the researchers noted that an “essential tremor-like” pattern was the most common type in their neuropathy patients.¹ If a neurologist is not thinking about the neuropathy as a possible tremor cause, the default diagnosis will often be essential tremor.

There are some distinguishing features, though. In CMT patients, the tremor stability index, a measure of how consistent the tremor frequency is over time, was significantly higher than in essential tremor, meaning the neuropathic tremor was more variable and less rhythmically stable.⁴ In practical terms, neuropathic tremor can look slightly more irregular or jerky compared to the smoother oscillation of essential tremor. Additionally, neuropathic tremor does not shift its frequency when you add weight to the hand, whereas a mechanical or enhanced physiological tremor typically slows down with loading.⁵ That weight-loading test can be a useful clinical clue.

Another important distinction is between true tremor and what might be called “pseudotremor” or sensory ataxia. When large sensory fibers are severely damaged, you can lose the ability to sense where your limbs are. The resulting unsteadiness when trying to hold a posture can look like tremor but is actually a different phenomenon: constant corrective adjustments by a motor system flying blind. A classic way to check for this is to see whether the unsteadiness gets dramatically worse when you close your eyes, removing the visual compensation that was substituting for the lost proprioception. True neuropathic tremor, by contrast, is generated by central oscillators and is relatively stable regardless of whether your eyes are open or closed.

For clinicians investigating a tremor in someone with known neuropathy, the diagnostic workup typically includes nerve conduction studies to characterize the neuropathy, accelerometry or electromyographic tremor recordings to quantify the tremor, and blood tests to look for treatable causes of both conditions, such as inflammatory markers or paraproteins.⁹ The goal is to identify the type of neuropathy, rule out other causes of tremor, and determine whether the tremor is truly neuropathic rather than a coincidental essential tremor or drug-induced tremor.

Treatment Options for Neuropathic Tremor

Treating neuropathic tremor is genuinely difficult, and the evidence is thinner here than you might hope. The first and most logical step is to treat the underlying neuropathy when that is possible. In inflammatory neuropathies like CIDP, immunotherapies including steroids, intravenous immunoglobulin, and plasma exchange can improve nerve function. However, as noted earlier, the tremor frequently persists even when the neuropathy improves, which is consistent with the idea that once the central motor circuits have been destabilized, they do not necessarily reset just because the peripheral trigger gets better.³

Standard anti-tremor medications like propranolol and primidone, which are first-line treatments for essential tremor, are sometimes tried for neuropathic tremor. The results are inconsistent. Some patients get modest benefit; many do not. Neuropathic tremor has a reputation among movement disorder specialists as being resistant to conventional drug therapy, which is one of the characteristics that makes it so frustrating to manage.

For patients whose tremor is severe and medication-resistant, deep brain stimulation (DBS) targeting the ventral intermediate nucleus of the thalamus has shown promise. This is the same brain target used for essential tremor and Parkinson’s tremor. The logic is sound: if the tremor is being driven by abnormal oscillations in the thalamus, then directly modulating that brain region with electrical stimulation should help. Case reports have documented marked, sustained improvement in neuropathic tremor with DBS over long-term follow-up.³ The intraoperative recordings that confirmed central oscillators in a patient with neuropathic tremor provided a strong rationale for why thalamic DBS should work in these cases.⁷ DBS is a major neurosurgical procedure with its own risks and is reserved for severe, disabling tremor that has not responded to other treatments, but for the right patients it represents a real option.

Physical and occupational therapy also play a role. Proprioceptive training exercises, which work to rebuild or compensate for the impaired sensory feedback loop, have shown benefit in improving upper limb coordination. One study found that combining stretching with proprioceptive loading exercises (Frenkel exercises adapted for the upper extremity) produced significant improvements in hand coordination measured by a standard timed peg test.¹⁰ While that particular study focused on cerebellar tremor, the principle of proprioceptive retraining is directly relevant to neuropathic tremor, where degraded proprioceptive input is a core part of the problem.

Wearable Devices and Practical Adaptations

For people living with neuropathic tremor day to day, adaptive tools and wearable technology can make a meaningful difference. Tremor-suppression orthoses, essentially wearable devices that dampen the shaking mechanically or with active motors, have been an active area of engineering research. A review of current devices found an average tremor suppression of about 83% across different designs. Active devices that use motors or actuators to counteract the tremor were the most effective, while purely passive devices relying on damping materials or viscous resistance still achieved around 75% suppression.¹¹ These numbers come from a mix of bench tests and real patient trials, with bench tests performing better, but even in patients the results were encouraging.

Beyond specialized devices, practical adaptations that occupational therapists commonly recommend include weighted utensils and pens, which can dampen fine-motor tremor during specific tasks. Non-slip mats, two-handled mugs, plate guards, and button hooks are all low-tech but meaningful quality-of-life tools. For people whose neuropathy also causes numbness in the hands, these adaptations serve double duty: compensating for both the tremor and the reduced grip sensation.

Voice-to-text software and touchscreen adaptations on phones and tablets can reduce reliance on fine hand movements for communication. Some patients find that stabilizing the forearm on a table or other surface while performing a task substantially reduces the visible tremor at the hand, because the postural component is taken out of the equation. These strategies will not cure anything, but they can keep a person functional and independent in ways that matter enormously to daily life. If you are dealing with neuropathic tremor, an occupational therapist with experience in neurological conditions is one of the most underused resources available and worth asking your doctor about.

When Tremor Appears Alongside Neuropathy by Coincidence

It would be misleading to suggest that every tremor in a person with neuropathy is caused by the neuropathy. Essential tremor is the most common movement disorder in adults, affecting an estimated 1-5% of the general population depending on age. Neuropathy is also extremely common, particularly diabetic neuropathy, which affects millions of people worldwide. Simple probability means that many people will have both conditions independently. A 65-year-old with diabetic neuropathy who develops a hand tremor might well have garden-variety essential tremor that would have appeared regardless of the neuropathy.

The clinical challenge is distinguishing coincidence from causation. A few features suggest the tremor is genuinely neuropathic rather than an incidental essential tremor. If the tremor appeared after the neuropathy was established, if it affects the more neuropathy-damaged limb preferentially, if it has an irregular or jerky quality, or if it does not slow down with wrist weighting, those features point toward a neuropathic origin. On the other hand, a strong family history of tremor, bilateral symmetric involvement, and improvement with alcohol or beta-blockers would point more toward essential tremor. In practice, the two conditions can coexist and may even reinforce each other, making a clean diagnostic distinction difficult.

Getting the distinction right matters because the treatment approach differs. Essential tremor responds reasonably well to propranolol and primidone. Neuropathic tremor often does not. Pursuing aggressive immunotherapy for CIDP with the expectation that the tremor will resolve may lead to disappointment if the tremor has become self-sustaining in central circuits. And conversely, dismissing a treatable inflammatory neuropathy as “just essential tremor” means missing a condition that, left untreated, will continue damaging nerves. If you have both neuropathy symptoms and tremor, bringing both to your neurologist’s attention and asking whether they could be connected is a worthwhile conversation to have.
