  • Hey there, welcome to Life Noggin.

  • Memory... is the diary that we all carry about with us.”

  • So says Miss Prism in The Importance of Being Earnest.

  • It’s a pretty accurate metaphor.

  • Memories hold our secrets, our feelings, and our experiences.

  • But what she doesn’t point out is that memories, just like diaries, can be lost.

  • Our thoughts and recollections of the past can be gone in an instant.

  • What we tend to picture when we think of memory loss is what’s known as retrograde amnesia.

  • Someone with retrograde amnesia can’t remember certain aspects of the past and things they

  • already knew.

  • Generally, amnesia affects a person’s short-term memory.

  • Theyll remember the name of their childhood dog, but might not remember what day it is

  • or what they were doing immediately before they lost their memory.

  • Amnesia can be caused by a stroke, heart attack, or head injury, just as a few examples.

  • Fortunately, amnesia usually resolves itself without treatment.

  • However, millions of people will experience some form of incurable memory loss in their

  • lifetime.

  • In fact, this year an estimated 5.5 million people in the US live with Alzheimer’s disease,

  • a disease that impacts the brain’s ability to form memories.

  • Essentially Alzheimer’s starts with a buildup of bits of a protein called beta-amyloid,

  • also known as plaque, in the brain.

  • The plaque gets in between nerve cells, and as more and more of it builds up, it damages

  • and kills brain cells, and Alzheimer’s progresses.

  • According to the Alzheimer’s Association, 1 in 10 people over the age of 65 has Alzheimer’s.

  • That’s a lot of people.

  • But what does memory loss mean for a person?

  • Is their personality gone too?

  • And what can be done for them?

  • Many researchers are asking, and answering, these questions.

  • Research shows that losing your memory to a disease like Alzheimer’s isn’t just

  • about forgetting facts you learned in school or the name of the street you grew up on.

  • It can progress into forgetting how to go through your daily routines like eating and

  • getting dressed.

  • Side effects of Alzheimer’s also include personality changes, ranging from apathy to

  • paranoia to indecision.

  • However, in an interview about his experience with the disease, one man who has been living

  • with Alzheimer’s for several years saidwere still in there.”

  • But researchersunderstanding of the disease can only go so far.

  • They can see the effects that Alzheimer’s has on people, but typically they don’t

  • fully comprehend the feeling of forgetting their own life.

  • According to a firsthand account from one individual who was diagnosed with early-onset

  • Alzheimer’s, in order to imagine the disease, you should imagine waking up after a dental

  • procedure or a surgerysome event that involves drugs that erase your short term memory.

  • But also imagine that youve woken up in a building you don’t recognize, surrounded

  • by things youve never seen before, and youre all alone.

  • Soon, people start coming into the room with you and talk to you like youve always known

  • them.

  • Maybe theyre your best friend or your kid or your spouse.

  • But you have no idea who they are.

  • This is terrifying and heartbreaking to imagine.

  • I don’t like to think about it.

  • But it’s reality for so many people, and it’s incredibly important to think and talk

  • about.

  • Alzheimer’s has no cure.

  • But we have many scientists and researchers to thank for devoting their time and work

  • to looking for

  • a cure.

  • As always, my name is Blocko and this has been Life Noggin.

  • Don’t forget to keep on thinking!

Hey there, welcome to Life Noggin.
