Summary
Vestibular migraine (VM) primarily affects middle-aged women, with headache preceding vertigo by years. Most patients exhibit normal physical and vestibular tests, but carbohydrate metabolism abnormalities are common.
Area of Science:
- Neurotology
- Neurology
- Ophthalmology
Background:
- Vestibular migraine (VM) is a recognized neurological disorder.
- It is a common diagnosis in neurotology.
Purpose of the Study:
- To characterize the clinical and epidemiological profile of patients diagnosed with vestibular migraine.
- To investigate the relationship between VM symptoms and patient demographics, medical history, and metabolic factors.
Main Methods:
- Retrospective, observational, and descriptive study design.
- Analysis of patient records from an outpatient VM clinic.
- Inclusion of demographic data, symptom history, physical examination findings, and laboratory test results.
Main Results:
- The study population comprised 94.1% females, with a mean age of 46.1 years.
- Headache preceded dizziness in 65.6% of patients, with a correlation between VM symptoms and the menstrual period.
- While most physical, auditory, and vestibular assessments were normal, 22.44% showed vestibular hyperreflexia, and 82% had carbohydrate metabolism abnormalities.
Conclusions:
- Vestibular migraine predominantly impacts middle-aged women.
- Migraine headache is typically the initial symptom, appearing years before vestibular disturbances.
- Normal vestibular and audiological evaluations are common, but metabolic alterations, particularly in carbohydrate metabolism, are frequently observed in VM patients.

01:15Equilibrium and Balance
8.0K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...

01:22Pathophysiology of Vomiting
4.0K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

01:29The Vestibular System
45.1K
The vestibular system is a set of inner ear structures that provide a sense of balance and spatial orientation. This system is comprised of structures within the labyrinth of the inner ear, including the cochlea and two otolith organs—the utricle and saccule. The labyrinth also contains three semicircular canals—superior, posterior, and horizontal—that are oriented on different planes.

Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...
