The occupational epidemiological literature on extremely low frequency electric and magnetic fields (EMF) and health encompasses a large number of studies of varying design and quality that have addressed many health outcomes, including various cancers, cardiovascular disease, depression and suicide, and neurodegenerative diseases, such as Alzheimer disease(More)
To examine the possible role of environmental factors in the cause of Parkinson's disease (PD), we reviewed mortality trends for PD in the United States from 1962 through 1984. We found that age-specific mortality for PD in all demographic groups had changed notably during this 23-year interval. Among whites of both sexes, substantial declines were observed(More)
Twenty-seven Parkinsonism patients and 31 controls, matched for age and verbal IQ, were tested on an objectively scored personality test (Minnesota Multiphasic Personality Inventory) at the beginning of the patients' levodopa therapy and three months later. Patients, but not the controls, were retested after 15 months of levodopa treatment. The patients,(More)
A rapidly growing tumor in the left posterior parietal lobe of a right-handed, 72 year old artist resulted in bilateral neglect and constructional apraxia that were greater on the right side of his painting than on the left. These changes indicate that a left posterior parietal lesion alters visuospatial perception and constructional ability on both sides(More)
From 1962 to 1984, age-specific mortality for motoneuron disease (MND) in the United States rose in all demographic groups over the age of 40. The increase was seen in both men and women, and both whites and non-whites, and was most pronounced in the elderly (eg, 378% in white women aged 80-84 years). Men were at 50% higher risk than women, and whites had(More)
To examine the effect of advances in the prevention of and therapy for PE, we reviewed mortality for PE in the United States from 1962 to 1984. Age-adjusted PE mortality increased by 67 to 100 percent between 1962 and 1974 for white and non-white men and women. From 1975 to 1984, these rates declined by 20 to 28 percent. Non-white PE mortality was greater(More)
From 1 January to 30 June 2012, 359 confirmed and 157 probable cases of measles were reported in Merseyside, England. The most affected age groups were children under five years and young adults from 15 years of age. Most cases have been sporadic. There have been few outbreaks in nurseries; however, no outbreaks have been reported in schools. Of the cases(More)
The effects of levodopa on tests measuring auditory and visual perception, auditory, and visual short-term memory, verbal learning, and on attention and concentration were studied in 29 patients with Parkinsonism. Thirty-two control subjects matched with the Parkinsonism patients on age, educational level, and verbal IQ were administered the same tests to(More)
