那時候的EEG 報告

EEG 報告

2012/02/21 15:14

今早媽媽很早起床,裝好昨晚弄給你今早當早餐的米包,然後準備午飯.怕到GH等看診會等上一個早上.來不及回來給你弄午飯,所以午飯也打包好帶去.

第1 次帶你去GH見兒科醫生DR.F是去年10月.12 月時做了EEG TEST.
今早是第2次見GH的Dr.F.大略跟醫生聊過你的狀況,用些supplements的事.還有最近幾個月,看到一些些進步,一些 self-stimultion behaviours減少了甚至沒有了,但有出現些新的behaviour-.ie.sniffing.醫生只是說sniffing is not harmful behaviour. 只要不是危險的動作、行為就沒關係.至於上回constipation的問題,媽媽告訴醫生說,比較好了.用Juicing,有益菌,維他命,礦物質後, 改善了.便便不硬了.大概2-3天,便便1次.醫生說很好啊,不需再用laxatives.(其實上回拿回來的藥,媽媽也不敢給你用)

其實今天真正目的就是為了看報告.EEG 報告真得很簡單,就只有兩句.是爸爸媽媽希望的結果,
"No epileptic activity was noted."

不過還是有一行寫著,"Apart from very occasional increase in slow delta activity over the left posterior quadrant,..."
當時沒有拿到報告在手,只是聽著醫生跟我們說,no epileptic during the test 兒科醫生覺得不需要用藥,認為沒有到那種嚴重的地步.雖然EEG TEST 只是說明當時EEG 的狀況,如果過程沒有發生epileptic,但確實在其他時間發生epileptic也是可能的.

醫生給了推薦信,讓爸爸媽媽5月再帶你回GH見神經科醫生和遺傳基因科醫生.神經科醫生會評估你需不需要做進一步檢查,或用些什麼藥.

從兒科診所走出來拿到報告副本看了後,媽媽問爸爸,為甚麼寫著" very occational increase in slow delta activity ..." "什麼意思?"爸爸也不知道.爸爸還回媽媽說,如果爸爸知道就當醫生囉!只有等著下次預約5月見神經科醫生問個明白.

媽媽回家不忘google,不過都是些technical的用語,看到媽媽霧煞煞.

上周五,Teacher Mariah 繼Teacher Terri跟媽媽反映你sudden eye-rolling.媽媽跟Teacher Mariah提起你的EEG 報告.問了上面那段句子,Teacher說是neuro problem.
而剛過去的周日,媽媽跟Ms Oh(你的ST)也探討關於這個問題.她說,有可能是internal fit.
媽媽很憂心.
SG visit to DAN! doctor時,媽媽沒有真正跟Dr, Erwin問個明白,但醫生有說,你有neuro方面的問題.開了一些幫助neuro & brain function的supplements.
媽媽只好自我安慰,也許真的只是neuro 的問題,因為醫生看過那簡單的報告,沒有特別的comment.也開了supplements那就試試用看,這幾個月再觀察你的狀況.
媽媽大略從ST,了解一些techinical terms,再google,看到了這麼一段的解說.心,有點沉重.

The four basic types of brain waves are alpha, beta, theta, and delta, with the type distinguished by frequency. Alpha waves fall between 8 and 13 Hertz (Hz), beta are above 13 Hz, theta between 4 and 7 Hz, and delta are less than 4 Hz. Alpha waves are usually the dominant rhythm seen in the posterior region of the brain in older children and adults, when awake and relaxed. Beta waves are normal in sleep, particularly for infants and young children. Theta waves are normally found during drowsiness and sleep and are normal in wakefulness in children, while delta waves are the most prominent feature of the sleeping EEG. Spikes and sharp waves are generally abnormal; however, they are common in the EEG of normal newborns.
Different types of brain waves are seen as abnormal only in the context of the location of the waves, a person's age, and one's conscious state. In general, disease typically increases slow activity, such as theta or delta waves, but decreases fast activity, such as alpha and beta waves.
Not all decreases in wave activity are abnormal. The normal alpha waves seen in the posterior region of the brain are suppressed merely if a person is tense. Sometimes the addition of a wave is abnormal. For example, alpha rhythms seen in a newborn can signify seizure activity. Finally, the area where the rhythm is seen can be telling. The alpha coma is characterized by alpha rhythms produced diffusely, or, in other words, by all regions of the brain.
Some abnormal beta rhythms include frontal beta waves that are induced by sedative drugs. Marked asymmetry in beta rhythms suggests a structural lesion on the side lacking the beta waves. Beta waves are also commonly measured over skull lesions, such as fractures or burr holes, in activity known as a breach rhythm.
Usually seen only during sleep in adults, the presence of theta waves in the temporal region of awake, older adults has been tentatively correlated with vascular disease. Another rhythm normal in sleep, delta rhythms, may be recorded in the awake state over localized regions of cerebral damage. Intermittent delta rhythms are also an indication of damage of the relays between the deep gray matter and the cortex of the brain. In adults, this intermittent activity is found in the frontal region whereas in children, it is in the occipital region.
The EEG readings of persons with epilepsy or other seizure disorders display bursts, or spikes, of electrical activity. In focal epilepsy, spikes are restricted to one hemisphere of the brain. If spikes are generalized to both hemispheres of the brain, multifocal epilepsy may be present. The EEG can be used to localize the region of the brain where the abnormal electrical activity is occurring. This is most easily accomplished using a recording method, or montage, called an average reference montage. With this type of recording, the signal from each electrode is compared to the average signal from all the electrodes. The negative amplitude (upward movement, by convention) of the spike is observed for the different channels, or inputs, from the various electrodes. The negative deflection will be greatest as recorded by the electrode that is closest in location to the origin of the abnormal activity. The spike will be present but of reduced amplitude as the electrodes move farther away from the site producing the spike. Electrodes distant from the site will not record the spike occurrence.
A final variety of abnormal result is the presence of slower-than-normal wave activity, which can either be a slow background rhythm or slow waves superimposed on a normal background. A posterior dominant rhythm of 7 Hz or less in an adult is abnormal and consistent with encephalopathy (brain disease). In contrast, localized theta or delta rhythms found in conjunction with normal background rhythms suggest a structural lesion.
