We have received the official reports from our last round of testing. Here are some bits and pieces...
The PET scan showed a mild hypometabolism of the left parietal, temporal and occipital cortex. The right hemisphere appears normal. The basal ganglia thalamus, brainstem and cerebellum showed a normal distribution of glucose metabolism. The gyri in the left posterior cortex are not very well defined compared to those on the right side. The architecture suggest cortical dysplasia. The right hemisphere abnormality is no longer present (very, very good news).**
The background activity during the awake state consisted of posterior dominant alpha rhythm at 8 Hz, which was bilaterally symmetrical and reactive to eye opening and eye closure (meaning the background rhythm is normal for age). During sleep, sleep spindles were seen bilaterally (don't know what this means). Hysparrhythmia was also seen during the sleep segment (that is bad...very bad). There were frequent right spike and wave activity along with independent left parietal-central-temporal spike and wave activity. Besides the right and left parietal-central-temporal activity there was also diffuse spike and wave activity. Besides these there was also temporal intermittent rhythmic theta wave activity seen in right and left side independently. Two types of spasms were captured. One was atonic spasms characterized by head nodding and the second was tonic seizures.
That about sums it up.
**Initial PET scan at 11 months of age stated the following...PET scan showed a large area of decreased glucose metabolism in the left hemisphere involving portions of the parietal, occipital and possibly frontal cortex. There is also a suggestion of a right parietal abnormality.
