- It is a rare (really really rare) neurological condition/brain disorder. Her neurologist has been practicing for 30 plus years and has only seen 3 prior cases.
- One half of the brain (the right hemisphere in Bowen’s case) is abnormally large (i.e. developmentally different).
- This was NOT something anyone did (believe me I asked..did I eat something wrong? Do the wrong things?). She had this before she was born-- it's a chromosomal defect that occurs developmentally in the womb.
- One of the concerns with HME is that the abnormally large hemisphere of the brain does not allow for the normal hemisphere of the brain to properly grow and develop.
- Another concern with HME is the side effect of seizures.
- The primary concern with seizures is if the severity of the seizure cuts off oxygen to the brain. HME should be the explanation of Bowen’s developmental delays to date. We have seen steps in the right direction thanks to therapy. The concern is moving backwards (i.e. learning and developmental impacts) resulting from seizures. Fevers lower the threshold for seizures stemming from HME.
- Anti-epileptic drugs do exist, although there are side effects and they do not work all of the time for all HME patients.
- Brain surgery in the form of a hemispherectomy exists in which the abnormally large hemisphere is disconnected and removed with the hopes that the normal hemisphere compensates for the lack of the other hemisphere (the technical term for this is “plasticity”).
So what's next? Her neurologist has referred her to a seizure specialist as well as a geneticist to sort of connect all the dots and figure out the best plan of action. The hard part is trying to get everyone to answer my phone calls :)
The fact that Bowen has only had one seizure and doesn't seem like the ''typical'' fit for HME is so encouraging for us and we know if anyone can progress and prove doctors wrong it's her! One really important to thing us is that we cannot allow the label to define her. She is just Bowen.
We will continue to keep you updated of course and we are always an open book for any questions you have.
