ORLANDO -- At least one concussion symptom was common in roughly two-thirds of pediatric sports medicine and orthopedic patients who had no history of the disorder, researchers reported here.

However, vestibular deficits -- common in roughly 81% of a separate sample of pediatric sports medicine clinic patients who did have concussions -- were not seen in this healthy group, according to research from Neil Khanna, BS, of the Feinberg School of Medicine in Chicago, Ill., and colleagues.

Harnessing a Stress Response May Prevent Hearing Damage

Too much noise can permanently damage your hearing, but in some cases, a little noise might be just what the doctor ordered. New research from the lab of Lisa Cunningham, Ph.D., at the National Institute on Deafness and Other Communication Disorders (NIDCD) hints at a new way to protect sensory hair cells in the inner ear from potentially damaging drugs: controlled noise exposure before the drug is administered.

Dizzying new perspectives of vertigo research

By Béla Büki

In the last three decades vertigo science has been revolutionized by new examination techniques and improving understanding of physiological principles. It used to be the case that a great percentage of patients with vertigo and dizziness did not receive any definite diagnosis; today not only has this ratio improved dramatically but in the majority of cases an effective therapy may be started. This changed neurotology, a speciality bordering between ENT and neurology, from a field of frustrations to a source of success. This is valid even in general practice because many of the bedside tests and simple treatments are easy to learn and do not require any sophisticated, expensive apparatus.

Part of right parietal cortex plays key role in upright perception, they say

by Stephanie Desmon and Helen Jones 

Johns Hopkins researchers say they have pinpointed a site in a highly developed area of the human brain that plays an important role in the subconscious recognition of which way is up and which way is down.

Teasing Out the Benefits of Meditation

The human brain is nature’s masterwork: From this highly organized lump of tissue emerge the wizardry of science and sublimity of art.

Too bad it can’t control itself. That same brain all too often torments its owner with unspeakable anxiety, suicidal sadness, and addiction to destructive chemicals, which the best efforts of psychiatric science and the psychotherapeutic arts can relieve with only limited success.

Rethinking Motion Sickness

In a cavernous basement laboratory at the University of Minnesota, Thomas Stoffregen thrusts another unwitting study subject — well, me — into the “moving room.” The chamber has a concrete floor and three walls covered in faux marble. As I stand in the middle, on a pressure sensitive sensor about the size of a bathroom scale, the walls lurch inward by about a foot, a motion so disturbing that I throw up my arms and stumble backward. Indeed, the demonstration usually throws adults completely off balance.

Yale University Acoustic Neuroma Study

Posted by Kerrie Denner

Dr. Elizabeth B. Claus from Yale University launched the collection of data from acoustic neuroma patients at the Acoustic Neuroma Association's (ANA) National Symposium in Los Angeles to initiate the first AN causation research study of this type. The goal of the study is to determine whether or not there are possible genetic risk factors that cause an AN.
