Essential palatal myoclonus: the click in your ear with nothing on the scan.
A rhythmic clicking that no one else can hear and no MRI can explain. The brain may be producing it, and that is a treatable finding.
Essential palatal myoclonus (also called essential palatal tremor) is a rare movement disorder in which the soft palate at the back of the roof of the mouth jerks rhythmically, often producing a clicking sound in the ear that the person can hear. Palatal myoclonus usually arises from damage in the brainstem or cerebellum, and that must be checked first. The ATNS Index of Neuroplastic Symptoms notes that when imaging shows no disease in those areas, which is what the word essential means, the person should be assessed for neuroplastic symptoms. Research increasingly supports this: many essential cases show the hallmarks of a functional movement disorder, a condition produced by learned brain pathways rather than by structural damage. These symptoms are real, not imagined, and they can improve with approaches that retrain the brain.
This page is about understanding the condition and the role the brain and nervous system can play in it. It is not a diagnosis. Your own clinicians know your case.
What essential palatal myoclonus is, and why imaging comes first
Your soft palate is the fleshy back part of the roof of your mouth. In palatal myoclonus it contracts in a steady rhythm, usually one to three times a second, and often keeps going during sleep. Many people notice it as a clicking or popping sound in one or both ears, caused by the small muscles that open the Eustachian tube snapping with each contraction.
There are two kinds. Symptomatic palatal myoclonus follows damage to a specific circuit in the brainstem and cerebellum, from a stroke, multiple sclerosis, injury or tumour. It usually involves different muscles, rarely causes a click, and shows a characteristic change on MRI. Essential palatal myoclonus is the label used when the click is present, the examination is otherwise normal, and the scan shows nothing wrong. Because the symptomatic form can be the first sign of a serious brain condition, the first job for your doctor is a careful neurological examination and an MRI.
The neuroplastic contribution
The ATNS Index of Neuroplastic Symptoms is specific here: when there is no evidence of disease in the brainstem or cerebellum, the person should be assessed for neuroplastic symptoms. That is exactly the situation the word essential describes.
Neuroplastic symptoms are real symptoms produced by learned pathways in the brain and nervous system rather than by structural damage. In movement disorders this is often called a functional movement disorder. The movement is real, it is not under voluntary control, and it is not pretending. The difference from a structural disorder is in the wiring: the brain has learned a pattern and runs it automatically, the way it runs a habit or a tic, often with attention and anxiety acting as the accelerator. Because the pathway was learned, it can be unlearned, which is why this diagnosis is good news rather than a dead end.
Clues that point toward a functional origin include:
- The clicking varies or stops when your attention is pulled elsewhere.
- It falls into step with another rhythm, such as tapping your finger.
- It began after a period of stress, illness or a frightening event.
What the research shows
Neurologists have been rethinking essential palatal myoclonus for more than a decade. A reappraisal of a large series of palatal tremor cases concluded that psychogenic (functional) palatal tremor may be under-recognised, and recommended that clinicians look deliberately for the positive signs of a functional movement disorder, such as variability, distractibility and entrainment, rather than assuming a structural cause.
A 2020 report described two patients with essential palatal tremor studied with EEG and EMG recordings time-locked to video. In both, the palatal movement was incongruous with any known lesion, variable, distractible and entrainable: in one, the palate fell into rhythm with the patient's finger tapping. The authors state that essential palatal tremor is now believed by many to be a functional movement disorder, and they used these recordings to make a definite diagnosis.
A 2021 clinical and imaging study of patients with palatal tremor confirmed the broad pattern: the essential form is associated with ear clicks and normal imaging, and the authors advise that a functional cause should be considered in such cases. The evidence is drawn from case reports and series rather than large trials, and some authors argue that a subset of essential cases may still be generated centrally by an unseen mechanism. But the direction is consistent, and it matches the index's position. For more on how the brain can produce real symptoms without damage, see our guide to functional neurological disorder.
Signs the brain may be part of the picture
- Your MRI and neurological examination are normal.
- The clicking comes and goes, changes speed, or disappears when you are absorbed in something.
- It started after a stressful period, a scare or an illness.
- Focusing on it, or worrying about it, makes it louder and faster.
- You have other symptoms that tests have not explained, such as tinnitus, dizziness, headaches or chronic pain.
Let the click be background
Sit somewhere quiet for three minutes. For the first minute, listen to the click deliberately, without trying to change it. Describe it as if to a friend: how fast, how loud, which ear, what it is like. For the second minute, hum a slow tune softly, or tap a finger at a different, slower rhythm than the click, and simply notice what happens. For the third minute, open your attention to every sound in the room, letting the click be one sound among many. The goal is not silence. It is to teach your brain that this sound is safe, and safe things can be left in the background.
A solution that addresses it
There is an approach that addresses the brain's role directly. Pain and symptom reprocessing, used for a wide range of neuroplastic symptoms including functional movement, begins with understanding how the brain learns and runs symptom patterns. It then builds skills: somatic tracking (noticing the sensation or sound with calm curiosity rather than alarm), reducing the sense of threat, graded return to normal activity, emotional awareness and expression, and acceptance and commitment skills (ACT) that loosen the grip of monitoring and worry. Trained clinicians deliver it, and digital programs are making it more accessible. It works best alongside the specialist care of a neurologist who is familiar with functional movement disorders.

What to do next
First, get the medical workup. See a neurologist, have an examination and an MRI of the brain, and make sure symptomatic palatal myoclonus has been excluded. Seek prompt attention if the clicking comes with new weakness, slurred speech, double vision, trouble swallowing, unsteadiness or numbness.
Second, if imaging is clear, ask your neurologist directly whether this is a functional movement disorder and whether your symptoms fit a neuroplastic pattern.
Third, if the answer is yes or probably, start learning and practising. The aim is not to force the click to stop but to change the brain's relationship with it, which is what allows it to fade. Our mindfulness and somatic exercises are a reasonable place to begin.
Questions people ask
Is essential palatal myoclonus a neuroplastic symptom?
It can be. Essential means no disease has been found in the brainstem or cerebellum, and the ATNS Index of Neuroplastic Symptoms says that in that case neuroplastic symptoms should be assessed. Research increasingly describes essential palatal tremor as a functional movement disorder, produced by learned brain pathways rather than damage.
Does functional mean I am making it up?
No. Functional and neuroplastic symptoms are real, involuntary and measurable. EMG recordings show the muscle genuinely contracting. The difference is that the pattern is generated by learned brain networks rather than by a lesion, which is why it can change and improve.
Can the clicking go away?
Yes. Functional movement disorders can improve substantially, sometimes quickly, when the person understands the mechanism and works with approaches that reduce attention, fear and threat around the symptom. Progress varies from person to person.
