mc_squared Posted August 24, 2009 Share Posted August 24, 2009 Suncream may be linked to Alzheimer's disease, say experts By Daily Mail Reporter Last updated at 7:24 PM on 24th August 2009 Comments (21) Add to My Stories Suncream stops millions of people each year from burning their skin, but scientists are now looking for a link between suncream and Alzheimer's disease The frightening possibility of Alzheimer's disease being induced by suncream is being investigated by academics. Millions of British holidaymakers use block to protect their skin from the sun every year. Now the University of Ulster says two of its experts have been awarded £350,000 by the European Union to explore the possible links between the suncream and the brain disease. They are leading a groundbreaking three-year research project into whether human engineered nanoparticles, such as those found in sunscreen, can induce neurodegenerative diseases such as Alzheimer's and Parkinson's. It follows a 2003 study by British doctors that found some leading brands of sunscreen lotions failed to stop the sun's damaging rays penetrating the skin. They recommended staying out of the sun or covering up when outside as the best way to protect against skin cancer. Professor Vyvyan Howard, a pathologist and toxicologist, and Dr Christian Holster, an expert in Alzheimer's, are conducting the latest research as part of a worldwide project called NeuroNano. The University of Ulster experts will be specifically looking at nanoparticles present in chemicals found in sunscreens and an additive in some diesel fuels - titanium dioxide and cerium oxide - and their connection to Alzheimer's and Parkinson's diseases.

Low-factor suncreams 'should be banned', health experts warn Professor Howard said: 'There is now firm evidence that some engineered nanoparticles entering intravenously or via lungs can reach the brains of small animals. 'Indeed they lodge in almost all parts of the brain and there are no efficient clearance mechanisms to remove them once there.' Enlarge The University of Ulster's Professor Vyvyan Howard (left) and Dr Christian Holscher, who are leading the groundbreaking research There were also suggestions that nanoscale particles arising from urban pollution had reached the brains of animals and children living in Mexico City, he said. 'It has recently been discovered that nanoparticles can have highly significant impacts on the rate of misfolding of key proteins associated with neurodegenerative diseases like Alzheimer's and Parkinson's disease. 'The brain itself is a very special organ. It cannot repair by replacing nerve cells, the ones you get at birth have to last all your life, which makes them peculiarly vulnerable to long term low dose toxicity.' The brain had built up some protective mechanisms but a major worry was that nanoparticles seemed to be able to circumvent them, he said. 'All this adds up to a new field of investigation. This research programme is deeply challenging and entails the gathering of entirely new knowledge in a field - neuronanotoxicology. 'It requires the marshalling of unique expertise, methodologies, techniques and materials, many themselves completely new and never before brought together in the required combination,'" said the professor. Latest figures show neurodegenerative diseases currently affect over 1.6 per cent of the European population, with dramatically rising incidence likely in part to the increase of the average age of the population. 'There is also some epidemiological evidence that Parkinson's disease is connected to environmental pollutants and it is often noted that, historically, reports of Parkinson's symptoms only began to appear after widespread industrialisation. 'The risk that engineered nanoparticles could introduce unforeseen hazards to human health is now also a matter of growing concern in many regulatory bodies, governments and industry,' said the professor.

Darlene_Ihnfsa Posted August 24, 2009 Share Posted August 24, 2009 so they want to try to stop alzheimer and parkinson? :thinking: i thought they were going to study if there's any connection in the suncream use and the fact of getting that at an early age or something.

Matter-Eater Lad Posted August 24, 2009 Share Posted August 24, 2009 I've decided EVERYTHING is going to kill us! Seriously, every year a thousands new things cause medical problems. Soon they will release a study finding happiness causes blood clots! Link to comment Share on other sites More sharing options...
Ambergris Posted August 26, 2009 Share Posted August 26, 2009 :confused: I didn't know this. I use sunscreen everyday. Btw, I also found this at wiki with regard to the nanoparticles present in the sunscreen (as TiO2 and ZnO): "There is evidence from isolated cell experiments that zinc oxide and titanium dioxide can induce free radical formation in the presence of light and that this may damage these cells (photo-mutagenicity with zinc oxide). However, this would only be of concern in people using sunscreens if the zinc oxide and titanium dioxide penetrated into viable skin cells. The weight of current evidence is that they remain on the surface of the skin and in the outer dead layer (stratum corneum) of the skin." I know TiO2 is considered a possible carcinogenic if inhaled. But I'm not really sure how much of it can be readily absorbed through the surface of the skin. I guess this is where the studies might be focusing I guess.

an angel Posted August 26, 2009 Share Posted August 26, 2009 So now everything we use in everyday life not only gives us cancer, but Alzheimer's as well. :confused: Link to comment Share on other sites More sharing options...
