DESIGNING A HEALTHY DIET FOR THE NEW YEAR

Every year, millions of Americans make New Year’s resolutions. The majority of these resolutions focus on diet in attempts to lose weight and be healthier. A new year is the perfect time to jumpstart a healthy diet to make the changes you want to see for yourself throughout the year. However, research shows 80 percent of resolutions fail by February. Many people strive for unrealistic goals, which ultimately set them up for failure.

EXERCISE HAS BENEFICIAL EFFECTS ON THE BRAIN

While exercise has long been known for its positive effects on physical health and its ability to heighten energy and help manage chronic health problems such as diabetes, hypertension and high cholesterol, exercise is now being lauded for its beneficial effects on the brain.   These benefits touch almost every aspect of life. Exercise helps sharpen short-term memory and improve long-term memory. This happens because exercise can reduce insulin resistance and inflammation and stimulate….

GETTING STARTED AND STICKING WITH IT

As we kick off 2018, you may be thinking about resolutions pertaining to your health and fitness. It’s easy to determine some ways to improve your physical, mental and emotional well-being. However, it’s not always as simple to stay motivated and make the new commitments part of your lifestyle. Now is the perfect time to set goals, whether it be for the number of days you intend to work out each week, how many steps you want to take each day or healthy meals you want to prepare for your family.

neutralize the effect of decreased vision on balance, Ramulu said. One possible explanation is reduced input from the eyes weakens the VOR, which maintains the effectiveness of vestibular balance. Common degenerative pathways or lower physical activity levels might also affect balance and be especially severe among those with visual impairment.


Balance problems coupled with blurred vision can indicate several conditions, such as type 1 or 2 diabetes, stroke, pink eye (conjunctivitis), eye injury, middle ear infection, labyrinthitis (an infection and swelling in the inner ear), acoustic neuroma, retinal detachment, epilepsy or ocular migraine, which can cause temporary blindness in one eye. A balance test is recommended for symptoms of rapid involuntary eye movement, vertigo or dizziness or gait abnormalities.

Balance and equilibrium help us know where we are in the world. They are controlled by signals the eyes, the inner ear and the sensory system send to the brain. The relationship between the inner ear vestibular and visual systems begins at birth; the vestibular system is the only fully functioning system we are born with. This system guides movement, which in turn guides the development of the visual system during our first years. When we are young, movement guides vision, but once we develop the necessary visual skills, vision begins to guide movement.


Two-thirds of the brain’s electrical activity is devoted to vision. Vision is so powerful a sense that it can override information from the other senses. This can be either beneficial or detrimental. Dizziness and disequilibrium are often the result of a vestibule-ocular reflex (VOR) dysfunction (a reflex that coordinates eye and head movement) and an unstable binocular (how well the eyes work together) system, says Dr. Nathan Davis, O.D. A dysfunction in balance is common after an acquired brain injury because of a disruption in the integration of the vestibular and visual systems. This sensory incoherence is like having the sound and the picture on a TV out of sync.


Visually impaired individuals and those with uncorrected refractive error, either near- or far- sightedness, have a significantly greater risk of diminished balance with their eyes closed than those with normal

BALANCE AND VISION ARE CORRELATED

vision, according to research from the University of California-Davis Health System Eye Center published in the journal JAMA Ophthalmology.


“Our research is the first large-scale population study to compare objective measures of physical balance across individuals with normal vision, uncorrected refractive error and the visually impaired and the first to link poor vision with diminished vestibular balance,” said Jeffrey R. Willis, an ophthalmology resident at the Eye Center and lead author of the study.


The take-away is vision may play an important role in calibrating the vestibular system to help optimize physical balance, says Pradeep Ramulu, M.D., Ph.D., with the Johns Hopkins University School of Medicine.


Willis added, “We know vision and balance are highly integrated in the brain, but we don’t fully understand the relative contributions of the visual, proprioceptive and vestibular systems in maintaining balance and preventing falls, especially among the visually impaired. ” The finding that worse balance was associated with poor vision was surprising, given that eye closure would be expected to
