Acoustic neuroma
An acoustic neuroma is a type of non-cancerous tumor that grows on a nerve close to the brain, used for hearing and balance, and causing problems such as hearing loss and unsteadiness. An acoustic neuroma may not cause any obvious symptoms at first. After manifestation symptoms tend to develop gradually and often include: hearing loss that usually only affects one ear, tinnitus (hearing sounds that come from inside the body), vertigo. Symptomatically, it’s very similar to Meniere’s disease and requires a thorough differential diagnosis.
Low iron levels
If you have anemia, your brain may not get sufficient oxygen. This can make you feel light-headed.
Brain tumors or brain injury
Brain disorders can cause balance problems if the involved part of the brain is responsible for controlling posture and balance. Dizzy spells will usually be accompanied by other neurological symptoms.
