In the United States we have an abundance of water. The country has 4.5 percent of the worldâs population yet almost 8 percent of its freshwater resources. It is home to the largest freshwater lake system in the world, the Great Lakes, which holds 6 quadrillion gallons of water (thatâs a 6 followed by 15 zeros). And the mighty Mississippi River flows at 4.5 million gallons per second at its mouth in New Orleans, supplying water to about 15 million people.
Lewy bodies are abnormal aggregates of protein that develop inside nerve cells in Parkinson's disease (PD), Lewy body dementia, and some other disorders. They are identified under the microscope when histology is performed on the brain. Lewy bodies appear as spherical masses that displace other cell components.
This type of dementia is diagnosed by taking a careful history of the pattern of symptoms, and by excluding other possible causes such as Vascular dementia and Alzheimer's disease. A brain scan may reveal brain degeneration, but the Lewy bodies can only be identified by examination of brain tissue after death. Lewy body disease is similar to Alzheimer's disease in many ways, and in the past it has sometimes been difficult to distinguish the two. It has only recently been accepted as a disease in its own right. It can occur by itself or together with Alzheimer's disease and/or Vascular dementia.
