NF2 - Move It Move It

Reason to Walk #1: Poor Balance (Disequilibrium) and Vestibular Rehabilitation Therapy

Date: April 21, 2018

Help Yourself if in need of Balance Recovery or Building Muscle Mass, or taking a Tumor-Drug Treatent

People with Neurofibromatosis Type 2 (NF2) develop walking issues for many reasons.

Most often the walking issue starts as a result of imbalance from tumor growth that results in vestibular nerve damage, which is a branch of cranial nerve 8 that runs from the brainstem to the vestibular system for which provides the inner ear for balance.

The growth of a schwannoma tumor on the vestibular nerve, vestibular schwannomas (VS)/acoustic neuroma (AN) , will result in an individual facing single-sided vestibular system damage and will be the start of equilibrium issues, disequilibrium/vestibulopathy. Single-sided vestibulopathy is vestibular system damage on one side of the head. It results in imbalance issues that an individual can recover from in a few days or a few months.

Bilateral vestibulopathy is vestibular system damage to the nerve on both sides of the head. "The symptoms typically include imbalance and visual disturbance. The imbalance is worse in the dark or in situations where footing is uncertain while spinning vertigo is unusual. The visual symptoms referred to as "oscillopsia," only occur when the head is moving (J.C., 1952)."[1] Bilateral vestibulopathy results in complete loss of the part of the body that distinguishes motion. With time, a section of the brain will help with adaption to motion, but vestibular rehabilitation therapy (VRT) is necessary.

Without VRT it is easy to develop muscle weakness and over time potentially result in an inability to walk at all.

Reason to Walk #1: Too much sitting - The Brain and Memory

Date: April 16, 2018

Do you have problems with memory? How many hours a day do you sit without walking, moving, or standing? "researchers have found that in people middle-aged and older, a brain structure that is key to learning and memory is plumpest in those who spend the most time standing up and moving."[1]

"The findings are based on interviews and tests of 35 cognitively healthy people between the ages of 45 and 75. Researchers at UCLA's Semel Institute and its Center for Cognitive Neuroscience queried the volunteers about their physical activity patterns and scanned their brains in an MRI. Then they gauged how self-reported sitting time or physical activity levels corresponded to a thickness in these critical brain structures."[1]

"The study subjects reported average sitting times of three to 15 hours a day. After adjusting for their subjects' ages, the researchers found that every additional hour of average daily sitting was associated with a 2% decrease in the thickness of the medial temporal lobe."[1]

Reason to Walk #2: Heart

Something to consider for individuals with high blood pressure, or at risk for heart related issues, for example if taking a tumor-drug medication; "walking briskly can lower your risk of high blood pressure, high cholesterol and diabetes as much as running."[AHA]

Researchers analyzed 33,060 runners in the National Runners' Health Study and 15,045 walkers in the National Walkers' Health Study. They found that the same energy used for moderate-intensity walking and vigorous-intensity running resulted in similar reductions in risk for high blood pressure, high cholesterol, diabetes, and possibly coronary heart disease over the study's six years."[AHA]

"Just get started, even if it's a few additional minutes per day."[AHA] "It's not all or nothing; it's step by step."[AHA]

"The findings are consistent with the American Heart Association's recommendations for physical activity in adults that we need 30 minutes of physical activity per day, at least 150 minutes of moderate activity per week or 75 minutes of vigorous activity per week to derive benefits."[AHA]

"Split up your walks into 10-15 minutes each."[AHA]
