The signs and symptoms of<unk>  can present as a persistent (insidious) onset or an episodic (sudden) onset. Persistent onset<unk>  is characterized by symptoms lasting for longer than one day and is caused by degenerative changes that affect balance as people age. Naturally, the nerve conduction slows with aging and a decreased vibratory sensation is common. Additionally, there is a degeneration of the ampulla and otolith organs with an increase in age. Persistent onset is commonly paired with central<unk>  signs and symptoms. The characteristics of an episodic onset<unk>  are indicated by symptoms lasting for a smaller, more memorable amount of time, typically lasting for only seconds to minutes.
