Abstract The paper discusses how patients with Lewy body dementia have delirium-like episodes, with flunctuating confusion, attention deficits, visual hallucinations, Parkinson-like rigidity and akinesia, interruption in consciousness and frequent falls. The paper looks at the similarities between dementia with Lewy bodies and Alzheimer's and Parkinson's diseases. The paper also looks at the diagnosis of dementia with Lewy bodies and the treatments available.
From the Paper "With the advancement of medical technology, more people are living longer, and in some parts of the world, healthier lives. Initially, children outnumbered older people all over the world; this is projected to change soon, as people over 65 years old will outnumber children under 5 years old. Almost 500 million people are over 65 years old, and by 2030, the world is likely to have 1 billion older citizens, which accounts for 13% of the total population (National Institute of Aging [NIA], p. 7). In developing countries, the number of older people is increasing rapidly; its population is expected to increase by 140%, in contrast to developed countries, where the increase in older populations is projected to increase by 51%. This change in demographics has many socioeconomic and health concerns, as older people are at greater risk for noncommunicable diseases, such as heart disease, cancer, diabetes, as well as neurodegenerative disabilities."
Abstract This paper studies how color vision works, from the cells involved and photoreceptor wavelengths to cone density, and neural connections. The paper describes the formation of free radicals and their neutralization by antioxidants, as well as explains the sources of antioxidants and how they work. The paper also discusses that addictive and poisonous properties of ethyl alcohol for human beings.
From the Paper "During metabolism in the body, free radicals are formed and are thought to damage cells. Free radicals are also caused by environmental factors, smoking and ultraviolet radiation. Oxygen occurs naturally in the atmosphere as a triplet..."
