Multiple sclerosis (MS) is a disease in which the immune system attacks the protective myelin sheath that covers and insulates the nerves and nerve fibers. Myelin damage disrupts communication between the brain’s neurons and between the brain and body and can damage the axons of the nerve cells. The damaged myelin forms scar tissue (sclerosis), causing nerve impulses traveling to and from the brain and spinal cord to become distorted or interrupted, which can lead to symptoms ranging from numbness and tingling to weakness, vertigo, pain, and speech, gait, and vision problems. Disease activity continues even when there are no symptoms. The process can continue to deteriorate the cells irreversibly.

Familial hypercholesterolemia (FH) is an inherited disorder that causes extremely high levels of LDL (low density lipoprotein or “bad” cholesterol), and no amount of diet or exercise can bring the numbers down. If not treated, these LDL levels can build up in the arteries and lead to heart attacks at an early age.

Tendons are bands of thick connective tissue that attach muscle to bone that can expand and push into the nerve when they become overused. The tendons act as a sort of spring, storing energy for movement. Tendonopathy is an umbrella term for the inflammation or irritation of a tendon, which causes pain and tenderness just outside a joint. When the condition is acute and short-term, it is referred to as tendinitis; when the pain continues for more than three months, it is considered chronic and is known as tendinosis.

While most people think they know what a concussion is, in reality there is no universally accepted scientific definition, and both diagnosis and treatment vary from physician to physician. The condition is elusive as well—a traumatic brain injury that alters the way the brain functions, with a range of symptoms that can vary in intensity and duration. Its effects can include headaches and problems with concentration, memory, balance, and coordination. Brain scans, using magnetic resonance imaging or computed tomography, often show no physiological change even though the person may be acting “not quite right.”

Essential tremor is one of the most common neurological disorders that causes uncontrolled shaking, usually in the hands or limbs. It also can affect the muscles of the larynx, causing loss of control of volume and pitch of the voice.

About 800,000 Americans suffer from a stroke each year—someone every 45 seconds. Stroke is the fourth leading cause of death in the U.S. but the greatest cause of long-term disability. Most people do not die from a stroke, but its effects cause more than half of all neurologic hospitalizations. The direct and indirect costs from lost work and lost productivity are estimated to run about $73 billion each year. May is National Stroke Prevention Month.

When TV dinners and fast food options first appeared, they were touted as a method of liberation from the kitchen. Swapping home-cooked meals for snacks, sweets, sugary drinks, and processed foods has led to a calorie-rich, nutrient-poor diet associated with today’s rise of obesity and chronic metabolic diseases like diabetes and hypertension.
