The most typical symptom that causes people to seek medical care is dizziness. Although the majority of these people may not have a condition that is life-threatening, the symptom is what worries them the most.

All of these people have a sense of imbalance with respect to their surroundings. Normal spatial balance, a multimodal function, requires visual and cerebellar inputs to the brain. There are two ways to interfere with it: directly or indirectly.

How can I tell if I'm feeling lightheaded?

Patients may refer to their sense of imbalance in a variety of ways. These consist of;

  • Dizziness
  • Giddiness
  • Whirling \sRotation \sSpinning
  • Lightheadedness
  • Shaking \sSwaying \sWobbling \sInstability

What types of vertigo are there?

These symptoms should be divided into the following categories for clinical purposes:

i. True vertigo.

ii. Pseudo vertigo.

True vertigo is defined as a sensation of rotation in one direction, which may be "objective" when the person perceives that the things in his surroundings are rotating around him or "subjective" when the subject perceives that he is rotating in his environment.

Pseudovertigo includes all symptoms of disequilibrium other than true vertigo and is far more common than actual vertigo.

What Leads to Vertigo?

The basic neurological causes of true vertigo include vestibular end-organ (labyrinth) dysfunction, vestibular division of eighth cranial nerve, vestibular nuclei in brainstem and their connections, flocculonodular lobe of the cerebellum, and very rarely cerebral hemisphere malfunction.

Pseudovertigo frequently results from non-neurological sources. True vertigo might include various symptoms in addition to the sensation of rotation. Impulsion—a sensation of being dragged to the floor or to one side—tinnitus, deafness, diplopia, or other localized neurological impairments are a few of these.

True vertigo manifests as a single episode or repeated, stereotyped bouts that last for a specific amount of time. Pseudovertigo can manifest as brief bouts or as an extremely lingering sensation that lasts for hours or even days.

When a patient complains of vertigo, dizziness, or another related condition, ask the following questions:

Is it genuine vertigo or fake vertigo?

2. Is it persistent or paroxysmal?

3. Is it accompanied by any other symptoms, such as tinnitus, deafness, diplopia, or nausea and vomiting?

4. Postural factors: Whether vertigo happens when the head moves, only in specific positions, or when the posture changes, etc.

5. Precipitating factors, such as stress, salt intake, exercise, and other factors.

6. Exacerbating variables, such as noise, coughing, straining, and exercise.

7. Factors that can be mitigated: a change in posture or head position.

8. Drug history, such as salicylates, antihypertensive medications, anticonvulsants, particularly diphenylhydantoin, and aminoglycoside antibiotics.

9. Past medical history: Head injury, ear injury or infection, prior upper respiratory infection

Diabetes, mental disorders, and others as well as infections.

10. Family history: Especially for neurofibromatosis, intracranial tumors, and familial deafness.
