Preventing Alzheimer's Neuro Note

Lisa Genova is a well known author and neuroscientist. In 2017 Genova gave a TED Talk on what can be done to prevent Alzheimer's. During her presentation, she goes over the physical cause of Alzheimer's and mentions that there are several factors that play a role in a person developing the disease. Some factors are: age, DNA, lack of deep sleep, poor cardiovascular health, and lack of aerobic exercise. So lets say you are over the age of 65, you are genetically predisposed, don't sleep a lot, have poor cardiovascular health, and don't exercise. Is there anything else you could do that could reduce your chances of developing Alzheimer's? Genova says that through learning new things our brains are creating new synapses and strengthening synapses, a process called neuroplasticity. Individuals who have more years of formal education, high degree of literacy, who take part in mentally stimulating activities, have more cognitive reserve, which is more functional synapses. So if a person who has all the factors that play into the development of Alzheimer's, if they have a high level of cognitive reserve, they have many more synapses that can act as back up synaptic connections, which leads them to not notice that something is wrong with their memory. She goes on to say that by knowing more about a subject creates more neural pathways, so if some are damaged due to Alzheimer's, you can take a detour and are still able to remember a topic/person/place. But simply knowing more things about a subject is not enough, the meaning behind the new learned item needs to be rich in the recruitment of sight, sound, associations and emotions. This means that doing crosswords isn' going to prevent the development of Alzheimer's, it means that activities like learning a new language, meeting new people, reading a book, etc. Genova concludes her presentation with three things she has learned from the people she knows that are battling Alzheimers "Diagnosis does not mean you are dying tomorrow. Keep living. You won't lose your emotional memory. You'll still be able to understand love and joy. You might not remember what I said five minutes ago, but you'll remember how I made you feel. And you are more than what you can remember."

Prior to watching this TED Talk, I knew that one way to prevent Alzheimer's was to do mentally stimulating activities. I thought mentally stimulating activities were things like crosswords and puzzles. I now know that a mentally stimulating activity is much more than that. Mentally stimulating activities are new experiences, things that you might have a little bit of knowledge about but taking it a step further and learning all about that new activity. This TED Talk made me realize that I need to read more books instead of watching Netflix and I should meet more people instead of napping with my dog Noodle. As a future OT, it is encouraging to know that there is something I can encourage my client's to do to "keep their minds young" and that being old and forgetful does NOT have to be part of the aging process. 

I chose to do a neuro note on Alzheimer's because I have a personal connection to the disease. My great-grandmother had it and my grandmother is beginning to show signs of it. This means that my dad, my sisters and I could also one day develop this disease. While it is too late for my grandmother to be proactive about preventing Alzheimer's, if my dad, sisters and I started to do some of the activities that Genova recommends, while it would not completely guarantee that we would not develop the disease, it would be better than doing nothing. Learning this new information is exciting and frustrating to me. I'm excited that there is something that can be done that can possibly prevent  this terrible disease, but I'm frustrated that it is too late for someone I love. I wish I could turn back time and get my grandmother to read more books, meet more people, and learn a new language, but I can't. Instead I choose to look at the positive points Genova pointed out at the end of her presentation. It does not mean that my grandmother will die tomorrow and that she needs to keep living her life. It means that even though she might one day forget who my family and I are, that she will still feel love and joy from doing things with us. At the end of the day I have to love her in the stage of life she is in and understand that she will remember that love.

What is the OTPF?

The OTPF stands for Occupational Therapy Practice Framework. It is composed of ideas, concepts, and philosophies that guide OT. It addresses domain of OT, the OT process, occupations, and client factors. The domain of OT is the areas in which OT's have a great wealth of knowledge and expertise.  This is what defines the focus of OT. Client factors, performance skills, performance patterns, context, environment, and activity demand are all under the domain of OT practice. Each part of the domain brings a different part of occupational therapy to the table.  The OT process is the actions that a practitioner takes when providing services that are client-centered and focused on engagement in occupation. This is what defines the delivery of OT. Throughout the process, occupation remains central. There is also collaboration with the client throughout the process.  Occupations are ordinary, part of daily living, and are often taken for granted. They can be special when the...

Occupation: More than just a job

If you were to ask random people how they would define occupation a vast majority of the responses would be job or employment. While that is one definition of occupation, occupational therapists use another definition. Introduction to Occupational Therapy  by Jane Clifford O'Brien defines occupation as "Activity in which one engages that is meaningful and central to one's identity." Today in class, we learned about decades from the 30's to modern day. We learned about the society, politics, big events, education, healthcare, occupational therapy, work, and leisure. With each presentation it was interesting to see how each topic of the presentation changed, specifically occupations, the OT definition. One occupation that changed throughout the time periods was the role of women. With the start of World War II, women went from keeping the house and children together to working and keeping the house and children together. After soldiers returned home from war, women ...

ALS Neuro Note

Alex Coriell was diagnosed with ALS in January 2013 at the age of 29. The video, Alex Coriell's Journey with ALS, walks you through Alex's journey. It shows you just how quickly the disease progressed and how positive Alex remained through it all. Alex went from being a normal 29 year old, father of 3 to a man of low muscle tone needing to eat through a feeding tube. The clip starts with Alex standing up in church telling his friends of his recent diagnosis and as the clip progresses, while his condition continues to get worse Alex remains positive and joyful. This clip showed me the importance of remaining positive, despite how bleak the diagnosis might be. It would have been so much easier for Alex to be an Eyeore, he chose to be a Tigger. It also makes me wonder if Alex's positivity had anything to do with how long he was able to live with ALS? In college, I had to take a class called Sport Psychology, that focused on how psychology plays a role in sports. Based on what...
