Paroxysmal positional nystagmus is the most frequent cause of vertigo in the overall population. Vertigo is a sudden feeling of dizziness or spinning inside your head.
The presence of paroxysmal positional nystagmus can cause short episodes of dizziness, ranging from mild to severe. These episodes are often triggered by sudden or specific movements of the head, such as lying down or sitting up on the bed or tipping your head up and down.
Paroxysmal positional vertigo is rarely serious. However, it may increase chances of falling, which may cause you mild to severe injuries. Hence, it would be best to receive efficient treatment for this condition from your doctor.
