Temporary workers may work full-time or part-time, depending on the individual case. In some instances, temporary workers receive benefits (such as health insurance), but usually benefits are only given to permanent employees. Not all temporary employees find jobs through a temporary employment agency.
1 Alzheimer's disease (AD) is the most common cause of dementia in people over age 65 with cause possibly related to amyloid plaques and neurofibrillary tangles.2  Almost all brain functions, including memory, movement, language, judgment, behavior, and abstract thinking, are eventually affected. Huntington's disease is a heredity disorder caused by a faulty gene. 2  Children of those with the disorder have a 50% chance of getting the disease. 3  Symptoms begin in those 30 to 40 years of age, beginning with personality changes such as anxiety and depression.
The development of dementia is slow. Typically, people that develop symptoms of dementia do so about 10 to 15 years after the initial diagnosis of Parkinson's disease. About 500,000 people in the United States have Parkinson's disease, and about 50,000 new cases are diagnosed each year.
