Fragment I
I have read, reviewed, and re-read the email from Jackson's Genetic Neurologist detailing the findings from his MRI. After the most recent re-read, I realized I completely missed the first finding, Unilateral Cerebellar Hypoplasia. So I did what any technologically savvy mother would do and I Googled it. I found it on the NINDS website, which can sometimes be too much information, if you know what I mean.
It was alarming to read the description, particularly because of the reference to Ataxia Telangiectasia which has been a topic of discussion for us before. Jackson now has two of the classic markers of AT, a thought which leaves me anxious. After careful consideration and a discussion with Jason, I emailed Ronni (Genetic Neurologist) to clear the air. Fully expecting a scolding for spending too much time online, the reply I received was not so light hearted.
His reply was as follows:
"Despite the finding of unilateral cerebellar hypoplasia, I still think that Jackson does not fit the clinical phenotype of children with AT, the MRI findings in patients with AT (regarding the cerebellar hypoplasia) are much more pronounced and probably more importantly, as far as I know, have never been shown to exhibit periventricular nodular hypoplasia. I also think that the periventricular nodular hypoplasia finding is the most significant finding on Jackson's MRI.
Having said all of this, as we have discussed before, most of genetic syndromes present with a wide variety and Jackson is still young enough to not present with the all the classical features of AT. Therefore, if you want us to rule this out, we can look into it."
Translation: We cannot say AT is not a possibility. They only way rule it out is to perform expensive time consuming genetic testing. An option we are set to discuss with Ronni this afternoon in his office.

A Googling We Go
- Unilateral Periventricular Nodular Heterotopia is a conditon of the brain in which gray matter is found in areas where the should be white matter.
- The outer layer of the brain is known as the cerebral cortex or the ‘grey matter’. It covers the nuclei deep within the cerebral hemisphere known as the ‘white matter’.
Grey matter is the closely packed neuron cell bodies form the grey matter of the brain. The grey matter includes regions of the brain involved in muscle control, sensory perceptions, such as seeing and hearing, memory, emotions and speech.
White matter is the neuronal tissue containing mainly long, myelinated axon, is known as white matter or the diencephalon. The nuclei of the white matter are involved in the relay of sensory information from the rest of the body to the cerebral cortex, as well as in the regulation of autonomic (unconscious) functions such as body temperature, heart rate and blood pressure. Certain nuclei within the white matter are involved in the expression of emotions, the release of hormones from the pituitary gland, and in the regulation of food and water intake. - The genetic mutation that causes this condition also has very serious cardiac implications, causing narrowing of the arteries and heart failure.
- Along with this diagnosis comes the official label "mentally retarded". The severity of which varies from case to case.

MRI Results
We finally have the results of Jackson's MRI from last week. Dr. Cohn, his Genetic Neurologist, called me this morning to discuss it. And this time there actually are some findings to discuss. Here they are in official medical jargon:
Jackson has unilateral right cerebellar hypolasia with intact left cerebellar hemisphere and vermis (although the inferior vermis is lightly small). He also has subtly smaller volume of the left cerebral hemisphere, probably related to cerebellar-cerebral connection. Additionally there is a finding of a left parietal periventricular nodular heterotopia.
What does this mean? I've only had a few hours to digest all of this - and even less time to research it. The basics that I understand at this point are as follows:
- The volume of Jackson's left hemisphere is slightly diminished in size.
- His inferior vermis on his right side is slightly small. (I don't know what this is either.)
- In his left hemisphere there is gray matter where there should be white matter.
This last finding is the most significant. This is a Neuronal Migration disorder, meaning that when the cells of Jack's brain were forming in utero, some of the cells didn't get the message as to where they should be and what they should be doing. Hence the gray matter where the white matter should be. This mislocation of gray matter causes developmental delays, gross motor issues, hypotonia, speech and language delays, and seizures. And while Jack has only had one seizure, post operatively there is significant reason to believe he will have more seizures.
As with many neurological disorders, the severity of issues varies greatly from patient to patient. This condition is rare and nearly never found in live males. Most afflicted males die in utero.
During our conversation this morning, Dr. Cohn said we would be doing further genetic testing specifically, the Filamin A gene. It is very likely that we will find a mutation of this gene, given this is the most common cause of these malformations.
I suspect I will find more information on these issues. I spent a brief period of time Googling the subject this morning and now have a stack of reading material to get through while I wait for my flight home.

I've still had no word from the Genetic Neurologist regarding Jack's scan from last week.
So I wait; for results, for possible evacuation, for freedom from the stifling air that surrounds me.

Travel Karma
The flight was bumpy, particularly towards the end, which would normally bother me, but I didn't really mind it so muh, feeling lucky just to have left the ground in the first place. When the plane landed, I grabbed my bag from the baggage claim belt and headed off to the rental car desk. I am a "Preferred" member so I don't even stop at the desk. I check the board of names and go straight to the car- where I am really disappointed to find a Ford Focus waiting for me. I wheeled back to the desk and politely asked the attendant if he could give me a different car. After a few minutes he winked and told me the location of the new car and told me to "Have fun". It wasn't until I saw the glow of the cherry red convertible Eclipse that I understood what he meant. I'm not normally a convertible kind of girl but I thought it would be fun. So I hopped in the car and hit the road. I turned on the Sirrus satellite radio to find The Smiths playing and cruised on down I-95.
Late night with Ms. Elizabeth Bennett
We spent the day at a cook out hosted by one of Jason's co-workers. It was a casual gathering, one which we were privileged to be included in, of the hosts' friends and family and we found ourselves at great ease with everyone. During our Bocce Ball rematch, Jack was bounding around, chasing the feral cats, occasionally throwing his own ball into the match. Shortly after the seventh point, I looked over to find that Jack was in the midst of another nose bleed. The game stopped, we tended to our boy, at which point we packed everyone up and headed home. The rest of the evening was uneventful.

You are here.
I am happy to report that our IEP meeting went really, really well. They have determined that Jack does indeed need five days a week of intensive preschool. Included in that is three, one on one sessions of speech and language and one session each of OT and PT. According to several people who have experienced IEPs, this is an incredible plan, aggressive and realistic and we are extraordinarily happy with the outcome.

A Blog in Three Acts: Act II
Q: What kind of friend abandons a friend in the midst of difficult times?
A Blog in Three Acts: Act I
First there is good news and there is bad news. The good news: At his PACT assessment today, we learned that Jackson does indeed qualify for their daycare. The bad news: PACT does not allow for pick up and drop off by Baltimore County. Translation: I'm in a pickle. A big sour puckering pickle.
