Imagine your little one forgetting the things she just barely mastered: the ability to feed herself, identify shapes and letters, and to walk and talk. You had hope that she'll live a long life before going through the challenges of a declining mind and body but for kids with "childhood Alzheimer's" these effects come sooner.

Officially titled "Sanfilippo syndrome," "childhood Alzheimer's" is so nicknamed because its symptoms mirror Alzheimer's disease. Since most parents are unaware of Sanfilippo syndrome, and therefore unable to recognize it. To make sure you aren't one of those parents, here are a few things you should know:

Sanfilippo is passed through parents

Sanfilippo is an inherited disease, meaning it is caused by gene mutations and passed to a child through parents' DNA. Specifically, Sanfilippo syndrome is autosomal recessive which means that two copies of the abnormal gene (the gene causing the disease) must be present in order to cause Sanfilippo. If both parents are carrying the mutation, the child has a 25 percent chance of having Sanfilippo syndrome.

If you think that you and your spouse may be a carriers of Sanfilippo, consider seeing a a genetic counselor so you can be aware of your child's chances of being born with Sanfilippo.

Symptoms generally arent apparent until age one

Usually, symptoms of Sanfilippo arent obvious for about a year. Occasionally an infant with Sanfilippo will have a bigger head than average but this isnt always the case. In general, children with Sanfilippo develop normally for a couple of years. Usually it's not until around age two or six that children with Sanfilippo begin missing developmental milestones, making their disease apparent.

Symptoms mirror Alzheimer's

As is apparent from its nickname, Sanfilippo syndrome is similar to Alzheimer's disease. Sanfilippo usually begins to be manifest through behavior issues, excessive activity and sleeplessness. Also, early on, children with Sanfilippo often get diahrrea, sinus infections and ear infections. Over time, kids with "childhood Alzheimer's" lose their ability to form words and sentences, eat on their own, walk and talk.

There is not a cure yet

Although there are some cases of people with Sanfilippo surviving into their thirties, most children with Sanfilippo Syndrome die in their late teens.

However, doctors are working to find a cure. In fact, several potential cures have already moved towards trial. You can help by donating to organizations that are researching cures, advocating for legislation that enables organizations to research cures, spreading awareness and offering support to families affected by this disease.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
