Alzheimer's disease is one of several brain disorders under the broad category of dementia. It is a gradually debilitating illness with no known cure. The first symptom is usually a slowly increasing memory loss, beginning between 40 and 65 years of age. As the disease progresses, the brain begins to deteriorate more rapidly, until it literally stops functioning. Of great concern is the projection that the number of people who will have Alzheimer's disease will double by the year 2030 because of the rising elderly population. Treating this population will escalate from the current estimate in excess of $2.5 billion to more than $6 billion. Speculation toward the increasing costs in money and workforce has led to an accelerated program in search of a cure or at least a symptomatic therapy for this condition. One of the most promising research leads is the striking connection between Alzheimer's disease and Down's syndrome and certain cancers: --Virtually 100% of patients with Down's syndrome who survive past age 35 show the same mental deterioration and identical brain changes seen in patients with Alzheimer's disease, including the presence of plaque and neurofibrillary tangles.--The presence of a high percentage of Down's syndrome among relatives of patients with Alzheimer's disease. --A high incidence of certain types of syndrome and among relatives of people who have Alzheimer's disease, such as leukemia, lymphomas, Hodgkin's disease, and immune system disorders. The key to the intercorrections between Alzheimer's disease and Down's syndrome seems to be a genetic component related to chromosome 21.(ABSTRACT TRUNCATED AT 250 WORDS)

Electromagnetic radiation is present in increasing amounts in our environment, and its potential effects on human (and animal) health has been investigated. It remains unclear whether the risk of acute childhood leukemia is associated with cumulative exposure to magnetic fields. An association with brain cancer and colon cancer has been suggested in electrical company workers. The radars used by police departments may increase the incidence of cancer. Electromagnetic radiation may play a role in a number of disorders such as depression and memory loss. It has been established that cell phones interfere with pacemakers only if direct contact occurs and have no effect if held in their normal position. Interferences have been reported between pacemakers and shop-lifting detectors.

Acute lymphoblastic leukemia is the most common malignancy in children. All current therapy regimens used in the treatment of childhood acute lymphoblastic leukemia include prophylaxis of the central nervous system. Initially it was thought that the best way of central nervous system prophylaxis is radiotherapy. But despite its effectiveness this method, may cause late sequelae and complications. In the programme currently used in Poland to treat acute lymphoblastic leukemia, prophylactic radiotherapy has been reduced by 50% (12 Gy) and is used only in patients stratified into the high risk group and in patients diagnosed as T-cell ALL (T-ALL). Complementary to radiotherapy, intrathecal methotrexate is given alone or in combination with cytarabine and hydrocortisone is given, as well as systemic chemotherapy with intravenous methotrexate is administered in high or medium doses (depending on risk groups and leukemia immunophenotype). Recent studies have shown that high dose irradiation of the central nervous system impairs cognitive development causing memory loss, visuomotor coordination impairment, attention disorders and reduction in the intelligence quotient. It has been proved that the degree of cognitive impairment depends on the radiation dose directed to the medial temporal lobe structures, particularly in the hippocampus and the surrounding cortex. Also, methotrexate used intravenously in high doses, interferes with the metabolism of folic acid which is necessary for normal development and the optimal functioning of neurons in the central nervous system. It has been proved that patients who have been treated with high doses of methotrexate are characterized by reduced memory skills and a lower intelligence quotient. The literature data concerning long term neuroanatomical abnormalities and neuropsychological deficits are ambiguous, and there is still no data concerning current methods of central nervous system prophylaxis with low doses of irradiation in combination with high doses of intravenous methotrexate.

Environmental pollutants, such as pesticides, herbicides, additives to food and water, and electromagnetic fields threaten public health by promotion of cancer, heart disease and chronic diseases of aging. Many of these pollutants cause adverse health outcomes by effects on mitochondrial function to produce oxidative stress through loss of the active site complex for oxidative phosphorylation, thioretinaco ozonide oxygen nicotinamide adenine dinucleotide phosphate, from opening of the mitochondrial permeability transition pore. Glyphosate, fluoride, and electromagnetic fields are examples of carcinogenic pollutants that promote loss and decomposition of the active site for oxidative phosphorylation, producing mitochondrial dysfunction and oxidative stress. Ionizing radiation has long been known to be carcinogenic, and non-ionizing electromagnetic fields from microwaves, radar, cell phones and cathode ray screens are carcinogenic and produce deleterious effects on capillaries, nerve cells, blood brain barrier, embryonic and germ cells, lenses and cardiac function. Adverse health effects of electromagnetic fields include cataracts, infertility, congenital malformations, cancer, lymphocytosis, leukemia, hearing loss, blindness, retinal hemorrhages, cardiac arrhythmias, dermatitis, hair loss, depression, memory loss, premature aging, heart attacks, and weaponized mind control. The hyperhomocysteinemia, suppressed immunity, and altered oxidative metabolism observed in atherosclerosis and dementia are attributed to deficiency of adenosyl methionine which results from increased polyamine biosynthesis by pathogenic microbes that are demonstrated in atherosclerotic plaques and cerebral plaques. Thus, environmental pollutants potentially promote diseases of aging, atherosclerosis, cancer, and premature aging by production of mitochondrial dysfunction.
