The brain, inner ear, muscles, joints, central nervous system, senses and blood vessels/heart all work together for normal balance. These links are called the vestibular system. Sometimes a disease or injury can damage this system causing dizziness, vertigo, trouble with walking or balancing, and sometimes difficulty with hearing and vision
Dizziness, which includes lightheadedness, motion sickness, vertigo and more, has many causes and symptoms, ranging from mild to the very disruptive and serious. Inner ear conditions most often cause dizziness, but reduced blood low to the brain, concussions and other injuries, and certain medications can all cause someone to be dizzy. If the condition interrupts daily life, medical attention is needed.
Conductive hearing loss is a form of hearing loss where the transmission of sound from the environment to the inner ear is impaired, usually from an abnormality of the external auditory canal or middle ear.
Tinnitus is commonly defined as hearing a sound in the absence of external sounds. Tinnitus is not a disease in itself but a common symptom, and because it involves the perception of sound or sounds, it is commonly associated with the hearing system. In fact, various parts of the hearing system, including the inner ear, are often responsible for this symptom.
