Rehabilitation of the Working Memory

6 comments
Memory loss is a common issue for mold-exposed patients. Until I began the brain rehabilitation component of our journey, I had no idea the problem involved my working memory rather than my short-term memory. The working memory is centered in the prefrontal cortex. One aspect of working memory involves "holding on" to thoughts and tasks.

For example, last week I went into the laundry room for white vinegar. I noticed the load of clothes needed to be moved to the dryer. I went back to the kitchen and forgot the white vinegar. I couldn’t "hold on" to my reason for entering the laundry room.



This is why I can focus on my blog or answer an email. I’m performing one task. Multi-tasking is a different story.

Kathleen Stein has written an in-depth look at the prefrontal cortex, titled The Genius Engine: Where Memory, Reason, Passion, Violence, and Creativity Intersect in the Human Brain. Stein explains it this way:

"Multitasking is a unique prefrontal talent that falls under the general rubric of 'working memory.' Working memory comprises the mind’s intersynaptic DNA, its central operating system for thinking-in-time. Or to use another metaphor, working memory provides the musical notation system from which the higher symphonies are composed."

The prefrontal cortex also handles attention. According to Stein, there are three types of attention:

1. Focus. This involves the ability to "stay with" a thought or skill. For example, the batter focuses on the ball as it leaves the pitcher’s hand.

2. Effortful attention. Stein describes this as "dedication, the drive that compels a person to persevere, keep striving, maintain discipline, and keep his eyes on the prize. It can be inextricably bound up with motivation, will, and desire."

3. Exclusionary/inhibitory attention. According to Stein, this form of attention "repels the continuous sensory barrage to which the brain is exposed, and runs interference against distracting thoughts, and inappropriate behaviors and remarks. When brain damage to the orbitofrontal PFC causes the loss of this attention, primitive drives and emotions can gain the upper hand over reason and social conventions."

If the prefrontal cortex is compromised through a toxic exposure, one or all three of these forms of attention will be adversely impacted.

One of the tools often used for patients with ADD, MS, balance disorders, autism, and sensory integration disorder, as well as those with traumatic brain injuries, is the Interactive Metronome. This biofeedback computer program is an assessment and treatment tool designed to improve the neurological processes of motor planning, sequencing, and processing.

The following 3-minute video, filmed by my son Reagan, shows me working with the IM under the guidance of psychologist and toxic mold researcher Dr. Robert Crago.

Prior to this recording I was unable to hit more than three greens in a row.
This type of rehabilitation can be difficult during a heavy period of detoxification. For the right person, at the right time, it can be an excellent tool. For a list of certified network IM providers, see the Interactive Metronome website.

Short term memory loss

5 comments
I have said little about the impact of the toxic mold exposure on my life. By necessity the focus of my life this last 19 months has been my children. I have been increasingly aware, however, that something is amiss with me. The pulmonary and neurological testing in December confirmed my suspicions. Further blood testing has also revealed abnormalities. By sharing a bit of my story I hope others will find help and hope.
These are the symptoms I have experienced: Chronic fatigue, ringing of the ears (tinnitus),disrupted sleep patterns, rashes, black tongue, emotional outbursts (to the point where my 10 year-old sobbed, "I want my old mommy back!"), joint pain, and general malaise.
I have read numerous times about something called brain fog. We have been on aggressive treatment for exactly a month and today I felt a level of clarity I have not felt for a very long time. Honestly, the inside of my head felt lighter. My pulmonary tests showed decreased lung capacity. I exercise so rarely I hadn't noticed the shortness of breath that comes with this. I did notice the decreased appetite that led to my weight loss in the last year. Mycotoxins play with leptin levels and several of us have high or low leptin levels.
By far my most debilitating symptom has been short-term memory loss and the resulting inability to multi-task. This is a very common symptom and easily dismissed as stress or age related. Let me immediately put the age issue to rest. My 19 year-old daughter has the same symptom and it showed up in her testing. I began to notice last year when I mixed up a number of appointments and missed some key events for my children. Uncharacteristic but understandable in light of the stress we were under. I could never find my cell phone or my glasses. I was having a much harder time in the kitchen. I would start something, leave it, and forget it. I had a hard time with my son's insulin doses. One time I gave him our dog's insulin by mistake. (It turned out fine. Just a humbling phone call to make to the doctor.) My kids couldn't depend on me to remember things they needed. I found myself saying, "Write it on the board or I won't remember." I started to forget where my car was parked. I couldn't find my keys. I couldn't remember what I needed at the store. This all was exacerbated when we re-located to Tucson. Parking lots are far more daunting without the familiar spots. Directions are very very difficult. I have to write them out in large print to read while I'm driving. I don't remember things I have told people. Numerous friends and family members have said to me, "You told me that already." It is indeed a disability and undoubtedly a result of mycotoxins at work in the brain. I have had two doctors assure me this is reversible and so I remain hopeful. Until then I am finding ways to adjust.
The other day my daughter gently "encouraged" me to buy a cell phone holster. I have thanked her numerous times because I haven't lost my phone one time. I keep a notebook with me and index cards nearby. I did miss an orthodonist appointment this morning for Colin. I wrote it down. I just couldn't find the paper.
