Health: Diagnosing “Essential Tremor” Movement Disorder

From a NextAvenue.org online article (01/07/20):

Essential Tremor InfographicEssential tremor is a common movement disorder — more common than tremors that come with Parkinson’s disease — and the most common neurologic condition affecting people 65 and older. It is estimated that 10 million Americans live with essential tremor, according to the International Essential Tremor Foundation.

About half of people with essential tremor inherited the condition. But the severity and affected body parts can differ from generation to generation, and researchers still haven’t pinned down the gene or genes responsible.

Tremors typically happen when people try to use their hands for a task. Activities such as shaving can be difficult’ people often need to use safety razors or electric razors to avoid cutting or nicking themselves. Also, difficulty holding a utensil makes eating a challenge for many people with essential tremor.

Health: Heart Disease, Stroke Deaths Are Rising, Even In Healthy States

From a Wall Street Journal online article (01/14/20):

Americans are dying of heart disease and strokes at a rising rate in middle age, normally considered the prime years of life. An analysis of U.S. mortality statistics by The Wall Street Journal shows the problem is geographically widespread. 

Heart Disease Management by age group WSJ from National Center for Health Statistics CDCDeath rates from cardiovascular disease among people between the ages of 45 and 64 are rising in cities all across the country, including in some of the most unlikely places.

In the Journal’s analysis, three metro areas east of Colorado’s Rocky Mountains—Colorado Springs, Fort Collins and Greeley—recorded some of the biggest increases. Death rates in each rose almost 25%. The three cities boast robust access to exercise and health care. There are bike trails, good heart-disease treatment-and-prevention programs and nearby skiing and hiking.

Medical: “Mohs Micrographic Surgery” For Skin Cancer Explained

Named after the late Frederic Mohs, M.D., Mohs micrographic surgery is a highly precise excision technique in which the cancer is removed in stages, one tissue layer at a time. After each removal step, the layer is examined under a microscope to determine whether cancer remains in the patient’s skin and, if present, where exactly it is located so that the surgeon can pinpoint where to remove the remaining skin cancer. This allows for the smallest scar and best cosmetic result.

Health Infographics: How Exercise Creates “New Neurons In Aging Brains”

Researchers have also documented clear links between aerobic exercise and benefits to other parts of the brain, including expansion of the prefrontal cortex, which sits just behind the forehead. Such augmentation of this region has been tied to sharper executive cognitive functions, which involve aspects of planning, decision-making and multitasking—abilities that, like memory, tend to decline with healthy aging and are further degraded in the presence of Alzheimer’s. Scientists suspect that increased connections between existing neurons, rather than the birth of new neurons, are responsible for the beneficial effects of exercise on the prefrontal cortex and other brain regions outside the hippocampus.

Video Interviews: Neuroscientist Daniel Levitin On Aging Well (PBS)

As a neuroscientist, professor emeritus of psychology, musician and best-selling author, Daniel Levitin has extensively studied the brain and its impact on aging. His latest book, “Successful Aging,” explores the questions: what happens in the brain as we age and what are the keys to aging well? NewsHour Weekend’s Christopher Booker recently spoke to Levitin to learn more.

New Books: “The Shapeless Unease – A Year Of Not Sleeping” By Samantha Harvey (January 2020)

The Shapeless Unease A Year of Not Sleeping Samantha Harvey book January 2020In 2016, Samantha Harvey began to lose sleep. She tried everything to appease her wakefulness: from medication to therapy, changes in her diet to changes in her living arrangements. Nothing seemed to help.

The Shapeless Unease is Harvey’s darkly funny and deeply intelligent anatomy of her insomnia, an immersive interior monologue of a year without one of the most basic human needs. Original and profound, and narrated with a lucid breathlessness, this is a startlingly insightful exploration of memory, writing and influence, death and the will to survive, from “this generation’s Virginia Woolf” (Telegraph).
