Working Diagnosis: Vestibular Migraine (VM) - Most Likely
This presentation fits vestibular migraine (VM) most closely. The key features supporting this are discussed below.
Why Vestibular Migraine?
1. Episodic brief vertigo with motion sensitivity
VM produces episodic vestibular symptoms of variable duration. Very short-lived episodes (seconds) are frequently reported by individuals who otherwise have clear-cut VM. Harrison's (2025) notes: "Motion sensitivity and sensitivity to visual motion (e.g., movies) are common [in vestibular migraine]." The patient's difficulty seeing moving objects is a direct expression of visual motion intolerance, a hallmark interictal feature of VM. - Harrison's Principles of Internal Medicine 22E, p. 971
2. Motion sickness as a diagnostic pointer
The history of motion sickness and difficulty with swings is highly relevant. Cummings Otolaryngology documents that 49% of children with migraine experienced severe motion sickness vs. 10% in controls, and 51% of adults with migraine report motion sickness compared to 20% of tension headache patients. This strong epidemiological link between migraine and motion sickness is well-established. - Cummings Otolaryngology, p. 3229
3. Absent aural symptoms reliably excludes Meniere's disease
There is no tinnitus, no aural fullness, no fluctuating hearing loss - the cardinal triad of Meniere's disease is absent. Harrison's explicitly states: "Low-frequency hearing loss and aural symptoms are key features that distinguish Ménière's disease from other peripheral vestibulopathies and from vestibular migraine." - Harrison's, p. 974
4. The absent phonophobia/photophobia does NOT rule out VM
This is a critical point - patients are not required to have photophobia or phonophobia during every attack. Per Scott-Brown's (Vol 2), headache need not be a prominent feature and photo/phonophobia are key symptoms that "should be specifically and carefully enquired about, since they are easily missed." The ICHD-3/Barany Society criteria require migraine features in at least two attacks, not all. - Scott-Brown's Otorhinolaryngology, p. 901
5. No neurological red flags
Absent allodynia, dysarthria, hypo/hypertonia, and absence of focal headache argue against central causes (brainstem stroke, posterior fossa lesion). No falls also reduces concern for a cerebellar process.
The figure below from Scott-Brown's illustrates typical everyday situations (supermarkets, crowded platforms, fairground rides) that provoke symptoms in VM patients - directly matching this patient's reported difficulty with moving objects and swings:

Differential Diagnoses to Consider
| Diagnosis | For | Against |
|---|---|---|
| Vestibular Migraine | Motion sickness, visual motion intolerance, brief episodic vertigo, no aural symptoms | Photophobia/phonophobia not clearly documented in attacks |
| BPPV | Brief duration (seconds), positional | No specific positional trigger reported; no Dix-Hallpike provocation documented |
| Meniere's Disease | Episodic vertigo | No tinnitus, no aural fullness, no fluctuating hearing loss - strongly against |
| Posterior circulation TIA | Episodic brevity | No dysarthria, no ataxia, no diplopia, no focal neuro signs, no cardiovascular risk factors mentioned |
| Persistent Postural-Perceptual Dizziness (PPPD) | Sensitivity to visual motion, motion sickness | Episodes are brief and paroxysmal, not chronic continuous dizziness |
| Orthostatic hypotension | Brief dizziness on standing | No relationship to posture/standing described; no near-syncope quality |
ICHD-3 / Barany Society Diagnostic Criteria for Vestibular Migraine
Definite Vestibular Migraine requires all of:
- A. At least 5 episodes of vestibular symptoms (moderate-severe), lasting 5 min - 72 h
- B. Current or past history of migraine with or without aura (IHS criteria)
- C. One or more migraine features during at least 2 vestibular episodes: headache, photophobia, phonophobia, or visual aura
- D. Not better explained by another vestibular or ICHD diagnosis
Probable Vestibular Migraine (applies here if full migraine history is not established):
- At least 5 vestibular episodes of moderate-severe intensity, 5 min - 72 h
- Only one of B or C fulfilled
- Not better explained by another diagnosis
Note: The very brief duration (seconds) in this patient technically falls below the 5-min threshold for definite/probable VM per current ICHD-3/Barany criteria. This may indicate this is the interictal motion sensitivity rather than a full VM attack, or that this is early/mild VM. This warrants further history-taking for longer duration episodes.
- Cummings Otolaryngology, p. 3228-3229; Scott-Brown's Otorhinolaryngology Vol 2, p. 901
Recommended Work-Up
- Detailed migraine history - personal/family history, headache diary, previous migraines (even childhood), identification of triggers (food, sleep irregularity, hormonal changes)
- Pure-tone audiometry - usually normal in VM; useful to exclude Meniere's (low-frequency unilateral loss) and rule out vestibular schwannoma
- Dix-Hallpike maneuver - to exclude BPPV as a contributing or concurrent diagnosis (BPPV and VM frequently co-exist)
- MRI brain with contrast - particularly if interictal eye movement abnormalities are found on examination, or if headache is atypical; excludes cerebellopontine angle lesions and posterior fossa pathology
- Vestibular function testing (VNG/caloric) - A directional preponderance may be found in ~50% of VM cases; canal paresis in ~25%
- Orthostatic BP measurement - given the very brief dizziness episodes (seconds), pre-syncope should be formally excluded
- VEMP (Vestibular Evoked Myogenic Potentials) - variable, non-specific in VM but can help differentiate from superior canal dehiscence
Management Framework
Acute symptom relief:
- Vestibular sedatives: prochlorperazine, cyclizine, or cinnarizine (not for long-term use)
- Triptan therapy if migraine headache co-occurs
- Antiemetics (domperidone) for nausea
Preventive (if attacks sufficiently frequent/disabling):
- Lifestyle: regular sleep, exercise, and meal schedules; identify and minimize triggers
- Pharmacological prophylaxis: propranolol, topiramate, amitriptyline (selected based on comorbidities)
- Supplements (low-level evidence): riboflavin, coenzyme Q10, magnesium
Vestibular rehabilitation:
- Especially effective for head and visual motion intolerance - directly addresses this patient's difficulty with moving objects and swings
- Note: progress can be slower in VM than in other vestibular conditions, and it may transiently increase headache frequency
- Scott-Brown's Otorhinolaryngology Vol 2, p. 902-903
Psychological:
- VM is associated with higher rates of anxiety/depression than other vestibular disorders
- The concept of migraine anxiety-related dizziness (MARD) should be considered
- Screen for secondary psychological effects and treat accordingly
Key Points for This Patient
- The combination of brief episodic vertigo + motion sickness + visual motion intolerance + absent aural symptoms in this patient is a textbook VM pattern, even in the absence of classic headache
- The "difficulty seeing moving objects" and "difficulty riding swings" map precisely to visual motion intolerance and head motion intolerance - two of the core interictal manifestations of VM
- The complete absence of tinnitus, aural fullness, and fluctuating hearing loss makes Meniere's disease effectively excluded
- The absence of neurological signs (no dysarthria, no allodynia, no tonal changes, no falls) makes central/posterior fossa pathology unlikely but does not completely exclude it
- A thorough migraine headache history must be obtained - patients often overlook or underreport headaches when vestibular symptoms are the chief complaint
- If the patient's episodes are truly only seconds in duration, confirm whether longer episodes are also present - VM can coexist with BPPV, and the brief seconds-long episodes may represent positional BPPV while longer VM episodes go unreported

No history of fall or focused headache reported. No allodynia, slurring of speech, hyper/ hypotonia. make it good english
Here is the clinical history rewritten in clear, professional medical English:
History of Presenting Complaint
The patient presents with episodic dizziness, each episode lasting only a few seconds, with no associated loss of consciousness. The patient reports a history of motion sickness and describes difficulty tracking moving objects visually, as well as intolerance to swinging activities.
On directed questioning, the patient denies any photophobia, phonophobia, osmophobia, or visual aura. There is no history of tinnitus, aural fullness, or fluctuating hearing loss in either ear. No focal or throbbing headache has been reported. The patient has not experienced any falls.
Neurological screening is negative for allodynia, dysarthria, and changes in muscle tone (neither hypertonia nor hypotonia is present).
Summary
A patient presenting with brief, recurrent episodes of vestibular dizziness lasting seconds, without loss of consciousness, accompanied by motion sickness and visual motion intolerance. The absence of auditory symptoms, headache, neurological deficits, and aura makes this a clean vestibular presentation warranting further evaluation to differentiate vestibular migraine from benign paroxysmal positional vertigo (BPPV) and other peripheral vestibular disorders.
