In the middle of the claim that mobile phone radiation in the long term can cause brain tumors, a new study appears and shows the electromagnetic wave can protect and even reverse Alzheimer's disease, at least in mice.
Not only that, the cell phone radiation is also a positive effect increased brain activity in mice that do not suffer from Alzheimer's, according to the researchers.
"We were surprised to find that exposure to mobile phones, beginning in early adulthood, protects mice memory that looks to develop Alzheimer's symptoms," said Gary Arendash, lead author of the study and researcher at the Florida Alzheimer's Disease Research Center of publication in the Journal of Alzheimer's Disease.
The researchers showed that older mice with Alzheimer's presents to the electromagnetic waves generated by mobile phones to eliminate deposits of beta-amyloid in the brain, a protein associated with Alzheimer's disease. Beta-amyloid clumps form of the brain called plaques, are characteristic of the disease. The scientists speculated mobile phone radiation will increase the temperature of the brain, causing brain cells to release evil plaque.
They suspect the same effect will appear in humans, so that cell phone radiation can be used to prevent and treat the debilitating disease for us, they said.
However, studies conducted in mice does not always translate would be useful for human therapy, so further research is still needed.
This study involved 96 rats, most of which are genetically altered to develop beta-amyloid plaques and memory problems mimic Alzheimer's disease as they age. Some rat is left untouched, so that researchers can test the effects of radiation on normal memory as well.
Mice with Alzheimer's and normal mice exposed to electromagnetic fields generated by the use of standard mobile phones to two 1-hour period each day for seven to nine months.
Rats were not really talking on the phone of course. Instead, they were placed in cages arranged around the antenna that produces cell phone signal. The cage is set at equal distances from the antenna and exposed to radiation normally emitted by cell phones attached to the human head.
Radiation and Memory
The results indicate if exposure phone begins when young adults aged Alzheimer's mice, before signs of memory disorders clearly visible, their cognitive abilities are protected. In fact, mice with Alzheimer's works as well as mice without dementia in terms of measurement of memory and thinking skills.
If a parent with Alzheimer's mice have demonstrated memory problems presented cell phone radiation, their memory impairment disappeared. The researchers confirmed this reversal may be caused by a slight increase in brain temperature that they observed in Alzheimer's mice after months of exposure to mobile phones. Higher temperatures may have helped the brain affected by Alzheimer's to remove the formation of new beta-amyloid, in which brain cells will release it.
Exposure to cell phone encourages even the memory of normal mice on a normal level.
Benefits to the memory takes many months to appear, indicating that a similar effect in humans may take many years. The researchers suspect that the main reason for this improvement involve the ability of electromagnetic radiation to enhance brain activity, increases blood flow which is larger and increases energy metabolism in the brain.
Memory tests used in mice was designed from the tests used to determine whether Alzheimer's disease, or signs of very early (mild cognitive), is present in humans.
"Because we chose the electromagnetic parameters are identical to cell phone use humans and rats tested in the task is closely analogous to human memory testing, we believe our findings can be quite relevant for humans," said Arendash.
Arendash and colleagues conclude that exposure to electromagnetic fields may help to prevent and treat Alzheimer's disease in humans. They are currently evaluating whether the device is different from the frequency and electromagnetic forces will result in faster and even greater cognitive benefit than those found in their current research.
There is some controversy over whether electromagnetic waves from mobile phones cause brain cancer. While many studies have found no risk, a review article last October concluded that several studies 'high quality' did show the associated risk.
World Health Organization and the National Institutes of Health is still conducting research on this topic, and some countries have issued guidelines for cell phone use, such as restricting its use for children.
This study found no evidence of abnormal growth of the rat brains of Alzheimer's after months of exposure to electromagnetic waves from mobile phones.
Not only electromagnetic waves of mobile pasa, nasal spray insulin in patients with early stage Alzheimer's disease can recover their memories, some researchers said the United States (U.S.).
Patients who received treatment for four months showed increased memory in several trials conducted over the past two months, a report by Reuters Health.
"We believe our results are very promising and they give a guarantee on future trials," said Dr. Suzanne Craft of the VA Puget Sound Health Care System and University of Washington in Seattle, who presented the findings at the Alzheimer's Association meeting in Honolulu.
Alzheimer's is a fatal disease that causes the incurable brain degeneration in people with 26 million people in the world. The most common form of dementia is Alzheimer's.
Several studies have shown that people with Alzheimer's have low insulin levels in the brain, even at the earliest stage. Insulin is essential for communication between brain cells and is required for brain function.
Craft's research team tested what would happen if they give insulin directly into the brain.
They studied 109 non-diabetic patients with early Alzheimer's disease or a condition called mild cognitive impairment.
One third of the patients getting a placebo and two-thirds received different doses of insulin that has content in the nebulizer and sprayed in their noses twice a day for four months.
Patients who received lower doses of insulin showed significant progress on all key measures of thinking and memory, and on the test capabilities of daily activities.
In 15 patients treated with insulin and agree to perform spinal fluid examination (spinal tap), the team found an association between memory improvement and advancement in the size of a key protein associated with Alzheimer's disease.
Craft said that the treatment is still far from useful for patients, but the findings were strong enough to be studied in large clinical trials.
Alzheimer's drug is currently only dealing with symptoms only, but so far no drug that can improve the memory of patients with Alzheimer's.
