A Scientific Glimpse Into Alzheimer's Disease

The sixth-leading cause of death we cannot forget.

June is Alzheimer's Awareness Month. So in honor of the month, take a minute to learn about the disease and its implications.

Everyone knows what Alzheimer's disease is. It's the chronic, tragic disappointment you see on a person's face, in reality or in the movies, when her loved one cannot remember their cherished memories together. For most of us, memory is a faculty of our brain that we take for granted. We rely on it everyday, from knowing the route to work to the name of that distant cousin at family parties to avoid awkwardness. Our memory has been there for us — except when we are trying to find our keys.


Alzheimer's disease is usually associated with a wrinkled face, gray hair and slow pace. Though the majority of Alzheimer's patients are 65 and older, Alzheimer's is not an expected part of growing old. Alzheimer's disease is an irreversible, progressive disease, meaning it worsens over time, and causes memory, thought and behavior deterioration. It is the sixth leading cause of death in the United States and third amongst the elderly population. How is this disease persisting? What even IS Alzheimer's? Let me first clear up the common misconception that dementia is Alzheimer's disease.

Dementia is NOT Alzheimer's disease. According to the Alzheimer's association, dementia is "a general term for a decline in mental ability severe enough to interfere with daily life." Alzheimer's disease is the most common FORM of dementia, accounting for 60-80 percent of dementia patients. The second most common form is vascular dementia, which usually occurs after a stroke. Another misconception is that dementia is "senility." But this implies that reduction in mental abilities is a normal part of aging.

To be considered to have dementia, at least two of the following symptoms must be greatly impaired: memory, communication, ability to focus, reasoning and judgement and perception. Though memory loss issues does not mean one has dementia or Alzheimer's disease, it is best to get checked out by a doctor. The saying, "better safe than sorry" is pertinent in early detection for dementia as treatments will be available sooner.

What causes Alzheimer's disease? Let us delve into the category Alzheimer's fits in: neurodegenerative disorders. These are also called tauopathies, which share an accumulation of the hyperphosphorylated (fully saturated phosphorylated sites) form of a protein called tau in the affected neurons (brain cells) of patients.

In research I have done with Dr. Kuo at Michigan State University, we investigated different forms of the protein tau and compared the levels at which they aggregated through multiple procedures and experiments. Through the seven weeks of research, we confirmed that a couple of the forms of tau are contributors to the accumulation of neurofibrillary tangles, which are found in patients with Alzheimer's disease and are thought to assist with cell death in the brain.

Cognitive decline can be better prevented through some simple adjustments to one's lifestyle. Doing cardiovascular workout, taking an educational class, maintaining proper health of the heart, taking preventative measures with safety (seatbelt, helmet, etc), eating a healthy diet, getting an adequate amount of sleep, taking care of mental health, being social and challenging the mind reduce the onset of brain function regression.

Forty-seven million people are suffering from Alzheimer's and other forms of dementia from all around the world. This means millions and billions of hearts are breaking and money is being spent because a loved one lost the ability to recognize and act the way he used to. Family members are acting as caregivers, spending more than $5,000 a year for someone with Alzheimer's. Unfortunately, as of now, the terrible truth is there is no cure. To help the Alzheimer's Association, spread awareness of the disease by sharing on social media, making a donation, advocating for Alzheimer's patients' families against Congress, walking for "Walk to End Alzheimer's," or more through this website. Let's not forget the lives neurodegenerative diseases have taken — make their lives unforgettable through awareness and a healthy lifestyle.

For a long time, Goya has been a staple in some Latino households. People carry around jars of Adobo when they eat at friend's houses and packets of Sazón Goya can be found in almost everyone's pantry. Many BuzzFeed lists, videos, and memes aimed at Latinos reference Goya somewhere.

But in a year that just keeps hitting us with bad news, Goya Foods CEO Robert Unanue said that Trump was an "incredible builder" and that the US was "blessed" to have him as president at a White House event on Thursday.

Raven Baxter Was Our Favorite Teen Fashion Icon And We're Still Recreating Her Best Looks, Here

We take a look at Disney's most fashion-forward show to recreate some iconic looks.

Disney Plus

I grew up in the early 2000s. And, like any child at the time, I was hooked on Disney Channel shows. My favorite was and is "That's So Raven."

Raven is a teenage psychic navigating life in hopes of not revealing her powers. Only her family and close friends know she has them. Her powers oftentimes get her in trouble, which is where the comedy comes in. But, they also teach her and her friends sentimental life lessons.

Sobriety is so underrated, even when it comes to healthcare. The instant gratification of a substance or drink isn't exactly as gratifying as some people may think. For those of you who've never been hungover, consider yourself lucky — a hangover is biologically horrifying. A hangover is not instant gratification, so who are we kidding when people say "it just feels good." Being healthy actually feels good and won't hurt you or your bank account in the morning. The best way to be healthy is to choose sobriety.

Ah, yes. The juice cleanse. Yet another popular diet trend that promises to magically solve all of your health, nutrition, and weight issues.

Unauthorized Plastic Surgery Is Totally Unethical, And Happening WAY More Often Than We Know ‬

Plastic surgery for cosmetic enhancements has you looking more botched than beautiful and it’s painful to see.

Coming from someone who could afford numerous cosmetic enhancing procedures I would never in a million years cut up my face or my body. I'm pretty emphatic and when I watch these brainwashed victims with bandages and chronic inflammation (swollen lips) I literally feel their pain.

I've never been big on casual wear or athleisure. Most people who know me have never seen me in sweats. But, I do have those two or three pairs of sweats I can't resist climbing into the second I get home, the newest addition of which is the extra cozy Odyssey crewneck sweatshirt I got in an XL size to feel as close to being wrapped in a blanket at all times as possible.

In the past several months, I've started to expand my horizons, considering the ways in which I can bring my small wardrobe of comfortable bedroom clothing into the public. I've experimented with topping leggings and a sports bra with a denim jacket to the park, and an oversized sweatshirt worn as a dress, cinched at the waist with a belt when I'm out wearing leggings.

Insecure is one of my favorite shows ever. It really encapsulates what it's like being a Black 20-something, trying to navigate the many ups and downs of life. Issa, Molly, Kelli, and Tiffany are living their best lives in California while dealing with the twists and turns that come with that.

From life to relationships to careers, this show truly captures everything that runs through my mind on a daily basis. The show has a sense of realness and a strong frankness that makes you gravitate toward the characters and root for their success.

The waiter briskly moves towards us and stops just a foot away table, balancing the black serving tray stacked high with the ceramic plates that make-up our dinner. From memorization, he beings gently, but purposely, sliding everyone's orders in front of them and within seconds I'm am starring my meal.
