Light flicker - photosensitivity

Posted by Suspect on June 16, 2001 at 17:45:47:

An increasing number of people (in Sweden) are claiming that they are hypersensitive to electricity.

The patients with unusual hypersensitivity to electricity and light flicker were found to have extensive dental work with at least 2 large mercury amalgam fillings in their molars.

Many complained of Chronic Fatigue Syndrome (CFS), also known as Chronic Fatigue and Immune Dysfunction Syndrome (CFIDS), Fibromyalgia Syndrome (FMS), Multiple Chemical Sensitivity (MCS), and Gulf War Syndrome (GWS) which share many of same symptoms, and often occur together, but they do differ greatly only in the methods used for their diagnosis and treatment.
A 1994 study found that 70% of patients with FMS and 30% of those with MCS met the strict 1988 criteria for CFS.
Up to 67% of those with CFS and/or FMS reported a worsening of symptoms following exposure to air pollution,
cigarette smoke, solvent fumes or perfumes. Post exertional fatigue, however, was significantly more common in patients with CFS and FMS than in patients with MCS. This and other studies document the substantial overlap of commonly reported symptoms among CFS, FMS and MCS patients.
Many individuals and institutions contributed their time and expertise to the project. Scientists of Karolinska Institute in Sweden and World wide experts in academia served on this confidential project's advisory panel.


The nervous system comprises the brain, the spinal cord, and a vast array of nerves that control major body functions. Movement, thought, vision, hearing, speech, heart function, respiration, and numerous other physiological processes are controlled by this complex network of nerve processes, transmitters, hormones, receptors, and channels.
Although every major body system can be adversely affected by toxic substances, the nervous system is particularly vulnerable to them. Unlike many other types of cells, nerves have a limited capacity to regenerate. Also, many toxic substances have an affinity for lipids, fat-like substances that make up about 50 percent of the dry weight of the brain, compared to 6 to 20 percent of other organs. Many toxic substances can alter the normal activity of the nervous system. Mercury is known as one of the most dangerous.
Mercury vapor affect health
The nervous system is very sensitive to all forms of mercury. Methylmercury and metal vapors are more harmful than other forms, because more mercury in these forms reaches the brain. Exposure to high levels of metallic, inorganic, or organic mercury can permanently damage the brain, kidneys, and developing fetus. Effects on brain functioning may result in irritability, shyness, tremors, changes in vision or hearing, and memory problems.
The effects of neurotoxic substances on public health have increased recently because of new evidence that some neurological or psychiatric disorders may be caused or exacerbated by toxic agents in the environment. A noted case in point is Parkinson's disease. Researchers recently discovered that exposure to dental mercury amalgam fillings a highly toxic substance can cause Parkinson-like symptoms.

Many dentists working with mercury suffered from Parkinson's.

The Industrial Exposure and Control Technologies for OSHA
Regulated Hazardous Substances
U.S. Department of Labor March 1989 report of Occupational Safety and Heath Administration Assistant Secretary Mercury vapor report that health effects of exposure may be delayed. [USCG, 19851 Acute poisoning may result from inhalation of vapors of elemental mercury. If poisoning occurs by inhalation of fumes of metallic mercury, the syndrome is characterized by pneumonitis, lethargy or restlessness, fever, tachypnea, cough, chest pain, cyanosis, diarrhea & vomiting; atelectasisd emphysema, hemorrhage & pneumothorax often follow. Systemic effects of the poison start within a few hours & may last for days; death may ensue. Systemic signs of acute poisoning by elemental mercury include those referable to CNS.
The condition is characterized by metallic taste, nausea, abdominal pain, vomiting, diarrhea, headache, & sometimes albuminuria. After few days, salivary glands swell, stomatitis & gingivitis develop, & a dark line of mercury sulfide forms on inflamed gums. Teeth may loosen, & ulcers may form on lips & cheeks. In milder cases, recovery occurs within 10-14 days, but in others, poisoning of chronic type may ensue. Some of acute cases have resulted from exposure concentration of 1.2 to 8.5 ml Hg~cu m. [PATTY. INDUS HYG & TOX 3RD ED VOLZA,2B,2C 1981-82]
Systemic signs of acute poisoning by elemental mercury include those referable to the CNS.
As the most consistent & pronounced effects of chronic exposure to elemental mercury vapor are on CNS, the dental mercury amalgam fillings was a suspect for many years. Humans exposed occupationally to metallic mercury compound or Hg amalgams had significantly increased occurrence of lymphocytic aneuploidy but not structural chromosome aberrations relative to controls. Metallic mercury or Hg amalgams [NAT1L RESEARCH COUNCIL CANADA; EFFECT OF MERCURY IN THE CANADIAN ENVIRONMENT P.115 (1979) NRCC NO. 167391
Brain is critical organ in humans for chronic mercury vapor exposure; in severe cases, spongeous degeneration of brain cortex can occur as a late sequela to past exposure.
Common symptoms include depression, irritability, exaggerated response to stimulation (erethism), excessive shyness, Insomnia, emotional instability, forgetfulness, confusion, and vasomotor disturbances such as excessive perspiration and uncontrolled blushing. Tremors are also common; these are exaggerated when task is required but minimal when patient is at rest or asleep. A fine trembling of fingers, eyelids, lips, and tongue may be Interrupted intermittently by coarse shaking movements. Erethism and tremors are reversible. [GOODMAN. PHARM BASIS THERAP 6TH ED 19801 Acute intoxication from inhaling mercury vapor in high concentrations used to be common among those who extracted mercury from its ores. The condition is characterized by metallic taste, nausea, abdominal pain, vomiting, diarrhea, headache, and sometimes albuminurla. After a few days, salivary glands swell, stomatitis and gingivitis develop, and a dark line of mercury sulfide forms on Inflamed gums. Teeth may loosen, and ulcers may form on lips and cheeks.
Exposed to mercury man developed a syndrome resembling amyotrophic lateral sclerosis. Chronic effects of overexposure may include central nervous system depression. Chronic effects of mercury poisoning include a buildup of the metal in the brain, liver and kidneys. Symptoms include headache, tremors, loose teeth, loss of appetite, blisters on the skin and impaired memory. Target organs: eyes, skin, respiratory system, central nervous system, kidneys.
Medical conditions generally aggravated by exposure identified as routes of entry: dental amalgam, inhalation, absorption, eye contact, skin contact.

In patients exposed to combination of mercury dust & vapor, such changes have been reported.

Dental mercury amalgam fillings became suspect after Summers (1994) has proposed that set of unexplained symptoms in PGW veterans (skin rashes, chronic fatigue, headaches, sore joints, hair loss, irritability, insomnia, diarrhea, and depression) are related to mercury toxicity as result of installation of dental amalgams just prior to or immediately after service in PGW. This hipotesis asserts that installation of these amalgams resulted in clinically evident elemental mercury toxicity that continues as patients have ongoing exposure to mercury.
It is clear that the placement of dental amalgams results in systemic exposure to mercury (Gross and Harrisson, 1989;
Researchers suggest that Gulf War veterans and others who meet the diagnostic criteria for more than one
of CFS, FMS and/or MCS may all be suffering from dental amalgam poisoning but as yet not undefined common
syndrome. Summers et al. 1993). It is also clear that significant exposure to elemental mercury results in toxic syndrome with complex clinical presentation (Wyngaarden et al. 1992.) At the same time, relatively few human studies of adverse effects of amalgams have been done. Interest in diminishing elemental mercury exposure has resulted in proposals in Sweden, Denmark and Germany for restrictions on the use of mercury - containing dental amalgams.
To date, the hypothesis of unexplained symptoms in PGW veterans associated with the recent installation of dental amalgams has not been directly investigated to the best of our knowledge.
All, for example, seem to share heightened sensitivity to a diverse range of stresses, from physical exertion and infection to environmental exposures. In addition to chemical sensitivity, they often also report heightened sensitivity to bright lights, loud noises, hot and/or cold weather, and/or being touched. Until further research clarifies the nature of this overlap, however, the majority of physicians, insurers, attorneys and support groups continue to regard CFS, FMS, MCS and GWS for legal claims are trying to define as separate and distinct conditions.
The report Neurotoxicity: Identifying and Controlling Poisons of the Nervous System
U.S. Office of Technology Assessment
April 1990
NTIS order #PB90-252511 was reviewed and confirmed that similar effects are known for decades.

These patients also reported to suffer from skin, carpal tunel, computer vision, erectile dysfunction disorder, or severe menopause, neuropathy, artritis and asthma, as well as neurological symptoms when they are near computer monitors, fluorescent tubes, or other electrical appliances. Provocation studies with electromagnetic fields emitted from these appliances have, with only one exception, all been negative, indicating that there are factors such as dental mercury amalgam can effect the autonomic and/or central nervous system, resulting in the symptoms reported.

Many individuals who work at a computer video display terminal (VDT) reported a high level of job-related complaints and symptoms, including ocular discomfort, muscular strain, and stress. Surveys of computer workers show that eye and vision problems are the most frequently reported health-related problems, generally occurring in 70 to 75 percent of computer workers. The complex of eye and vision problems were suspected as related to neurotoxicity of dental mercury amalgam fillings, as all experienced same syndrome during computer use which has been termed "computer vision syndrome".

The elements of working at a computer which make it visually demanding include frequent saccadic eye movements (ocular motility) and continuous eye focusing (accommodation) and alignment (vergence) demands. Problems occur when the visual demands of the task exceed the visual abilities of the individual to comfortably perform the task.

Eye movements, eye focusing, and eye alignment processes involve repetitious muscular activity. The movement of each of the eyes is controlled by six extraocular muscles that are responsible for proper alignment of the eyes when viewing objects such as the computer monitor.
The ability of the eyes to change focus is controlled by the ciliary muscle, which exerts a force on the internal lens of the eye. In many respects, many computer related vision problems can be considered a form of musculoskeletal disorder associated with dental mercury amalgam fillings neurotoxicity, previously referred to as cumulative trauma disorder (CTD) or repetitive stress injuries (RSI).

The relationship between computer related vision problems and dental mercury amalgam fillings was suspected for many years.

Flickering light is one such aggravating factor and was therefore chosen as the exposure parameter in this study.

The study to determine if dental mercury amalgam fillings are related to neurological injury due to neurotoxicity and short distance of mercury fillings to brain centers.

All subjects complaining of photosensitivity, fluorescent light flicker, dizziness, migranes and electrical hypersensitivity were exposed to low frequency amplitude-modulated light.

The sensitivity of the brain to this type of visual stimulation was tested by means of objective electrophysiological methods such as electroetinography and visual evoked potential. A higher amplitude of brain cortical responses at all frequencies of stimulation was found when comparing patients with the control subjects, whereas no differences in retinal responses were revealed.

The suspected for long time neurotoxicity of dental mercury amalgam fillings causes non specific at this time injuries to eye nerves and brain centers responsible for brain cortical responses.

Brain SPECT scan performed on the many subject reveals mild frontal lobe perfusion, believed to be associated with constriction of brain capillary as consistent with heavy metals neurotoxicity.

The RAP music give you headaches and result in stupid posts on this board.
To change frequency follow instructions.

You need to start your electric stove.

If you do not have one buy one.

Than start all burners on.

Once read hot .... sit on it.

Onece temperature increases the frequency will be changing.

At the same time your HAM will be roasting.

Onece fully backed, chill it, than slice it and serve chilled with horseradish cream.

Enjoy the music.
