What Is Vertigo?
Vertigo is a sense of feeling  off-balance, dizziness, titling. People with this condition may feel like they are spinning when they are not, or their immediate surrounding is spinning when it’s not. Vertigo is not a disease itself, but a symptom of a condition. The occurrence of vertigo can last for a few seconds or a minute, they can last longer and happen intermittently for days mostly when the condition is severe. Simple movements are very intense for people suffering from this condition, and it can affect their everyday activities.
In some cases these unpleasant sensations are worse if you’re standing up, walking, or moving your head around. Many people describe these feelings as physically exhausting and tasking. Sometimes, the sensations are so severe that you feel nauseated or experience vomiting.
Being a woman and being older than 50 can up your risk of having a vertigo saga. A family member with this condition, or other factors, such as having a head injury, can also increase your chances of developing symptoms. Less common causes include migraines, medication, head injuries, and stroke.
The symptoms of vertigo will probably depend on what’s causing the problem and the type of it.
There are two main types  of vertigo although in recent times a new type of vertigo has been added to the list.
Central: When there’s a glitch in the brain central vertigo occurs, the glitch happens specifically in an area called the cerebellum in the human brain.
Peripheral: This is the most common type of vertigo, Peripheral vertigo is caused by an abnormal condition in areas of the inner ear or a problem in the vestibular nerve which connects the inner ear and the brain.
RSV-HSN: This is a new type of this condition that was recently discovered known as “recurrent spontaneous vertigo with headshaking nystagmus” (RSV-HSN).
Researchers made a video recording of the participants’ eye motions while they are sitting in a dark room, the examiner tested the subjects by moving their heads forward and then side to side for about 15 seconds. Results showed that with RSV-HSN had eye movements, known as “nystagmus,” that lasted longer compared with other types of vertigo, RSV-HSN involves more severe bouts of motion sickness.
People with RSV-HSN had symptoms that included nausea, vomiting, headaches, and intolerance of head motions. They experienced symptoms anywhere from a few times a week to once a year.
Symptoms  of vertigo vary from person to person. Your symptoms might be mild or severe, depending on what’s causing the issue.
