Brain changes: Are there connections between dementia and Traumatic Brain Injury (TBI)?

Every time I spend time with my mother now, I see increasing signs of her slipping away from me. Our conversations aren’t as friendly and light. Her affect seems flat. I feel no joy there. The mother I remember is absent. She refuses to wear her hearing aid, so it’s difficult to tell how much she is taking in of our conversations. She refuses to see a neurologist about these changes. I am left wondering how long she will be able to engage fully with us.

Alzheimer’s disease of course comes to mind. Five million Americans now suffer from Alzheimer’s. It is the most common form of dementia.

According to Alz.org, symptoms may include:

  • Increased memory loss and confusion.
  • Inability to learn new things.
  • Difficulty with language and problems with reading, writing, and working with numbers.
  • Difficulty organizing thoughts and thinking logically.
  • Shortened attention span.
  • Problems coping with new situations.

“The future ain’t what it used to be…” – Yogi Berra

These thoughts lead naturally into wondering about myself after one moderate traumatic brain injury (TBI) and a few concussions. Every brain injury is different depending on what part of the brain is damaged and how severely. In my case, I have had concussions before and after my TBI. The later one is probably a result of losses in coordination.

According to a study from the National Center for Biotechnology Information:

“Traumatic brain injury remains a major problem in modern societies, primarily as a consequence of traffic crashes and falls. In the United States alone, an estimated 1.7 million people sustain a TBI annually, of which 275,000 require hospitalization and 52,000 die.”

Moderate to severe traumatic brain injuries

Moderate to severe traumatic brain injuries can include any of the signs and symptoms of mild injury, as well as these symptoms that may appear within the first hours to days after a head injury:

Physical symptoms

  • Loss of consciousness from several minutes to hours
  • Persistent headache or headache that worsens
  • Repeated vomiting or nausea
  • Convulsions or seizures
  • Dilation of one or both pupils of the eyes
  • Clear fluids draining from the nose or ears
  • Inability to awaken from sleep
  • Weakness or numbness in fingers and toes
  • Loss of coordination

Cognitive or mental symptoms

  • Profound confusion
  • Agitation, combativeness or other unusual behavior
  • Slurred speech
  • Coma and other disorders of consciousness

Over the past 30 years, research has linked moderate and severe TBI to a greater risk of developing Alzheimer’s disease or another dementia, years after the original head injury. According to recent studies,

“Individuals who have had a head injury of sufficient severity to result in loss of consciousness were at approximately 50% increased risk of dementia compared with others.” https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3716376/

Now you see why I continue to read, write, think, watch Jeopardy! and exercise as much as possible…

Living in the simplicity of the present

I’ve been thinking a lot lately about how I have been changed by the experience of leaving city life behind. The greatest change has been my new ability to at least occasionally be in the present. I see now that before I moved here, I was constantly stressed out, and in distraction mode.

“Distractions are both more tempting and more destructive than we realize. It’s tempting to fill in every little minute of the day with productivity or distractions. Don’t. Leave some emptiness.”  – Zen Habits

It seems to me that cities are set up for constant outside noise and distraction. Any time you feel uncomfortable in any way, you can call up someone to go see, order some new kind of food, go out shopping or go see a movie. People in cities spend most of their time sitting in traffic or driving somewhere else. Cities are distraction machines, and the Internet is the ultimate, easily available escapism.

Being in the present means you are not planning ahead. You are sitting still, willing to be here now to observe and absorb your present surroundings with no thoughts of yesterday or tomorrow, no need to distract yourself. I find many of the observations of ZenHabits.com useful in my new mindset:

“If you’re filling your life with distractions, its probably because you’re afraid of what life would feel like without those distractions…”

To be honest, I never really had the time to gain full awareness of all of this until I moved away from modern American life. I knew I was anxious and not as relaxed as I wanted to be in the city, and now I see why. Cities raise our anxiety levels. I know because it took me at least a year away from a city to see how anxious I have been most of my life, and then find ways to allow myself to truly relax.

I have been a worry shopper my whole life. Once I solved one problem I moved on to the next one. Out here there is so little to worry about, leaving me much more time to focus on what is important to me. Now that’s a great new challenge! And what is important to me now is a few important relationships, and appreciating the natural world and its wonders.

We can sit and dream about so many things, but we would be wasting our lives. This present reality is all we get. Let’s learn to love it.
