Patients living with Parkinson's disease (PD) may be steered toward levodopa to manage symptoms. Presently, levodopa remains the most common PD drug. However, as with many medications, levodopa can create nutrient deficiencies with serious side effects when taken over time, with decreasing amounts of vitamin B6 and vitamin B12 being among the concerns. What Is Parkinson's Disease? PD is a progressive neurological disease in which brain cells that produce the neurotransmitter dopamine gradually die off. Low levels of dopamine cause various movement and non-movement related dysfunctions. The drugs that treat PD either replace or enhance dopamine, and central among these drugs is levodopa. What Is Levodopa? Considered the strongest medication available for managing PD and Parkinson's-like symptoms, levodopa was introduced in the 1960s and is currently classified as a central nervous system agent. Once taken, levodopa is converted into dopamine in your body. It is usually combin…

Regular exercise usually increases vitality, but a lot of people just don’t have the energy or motivation to get started on an exercise program. Although different factors can be involved, such as low thyroid, inadequate nutrition, or trying to force yourself into a boring exercise routine, a 2013 study showed that genetics can encourage either a love of movement or for your favorite recliner. Fortunately, there are ways you can compensate for couch potato genes.Rats given running wheels usually put them to good use, but scientists observed that some rats choose to run more than others. They separated high voluntary exercising (HVE) rats from low voluntary exercisers (LVE), and bred them through ten generations to produce final generations of super-HVE and super-LVE rats. The primary differences found between the two groups had to do with genes that control the neurotransmitter dopamine in the brain. The researchers believe that humans have similar genes that make them avid exercisers…
