When the patient has finished all the tests and placed them in front of the doctor, based on this information the doctor will make a diagnosis and design a treatment plan. Although it takes only a few minutes, it is never a moment of inspiration, but the result of reasoning, comparing and analyzing faster than the most advanced computers. First, from the seizures described by the patient’s family, the doctor determines which aspects fit the characteristics of epilepsy and which areas do not. Then, weighing the importance of whether the most important and basic aspects are consistent with epilepsy, and also comparing whether the patient’s condition is consistent with certain diseases that are not epileptic but have seizure symptoms, if the former is yes and the latter is no, the diagnosis of epilepsy will emerge. Next, the results of the EEG are first looked at and analyzed for any epilepsy-related waveforms exhibited by the EEG. In addition to a normal EEG, a slower frequency or increased slow wave is abnormal but not related to epilepsy, if there is an epileptic-like waveform is the greatest support for the clinical diagnosis. Both a normal EEG such as clinical symptoms very much consistent with epilepsy will be initially considered as epilepsy because as highlighted in the introduction to EEG due to recording conditions epileptic patients can present with a normal EEG. The initial determination of the diagnosis completes only the first step in thinking about the claim, and further determination of what type of seizure it is is based on the patient’s seizure profile and EEG presentation. This is a complex process of comparing the patient’s data with the characteristics of the various seizure types stored in the physician’s brain, leaving the similar ones to be gradually narrowed down and finally identified as a certain type of seizure. For example, a patient’s family said it was a generalized convulsion, but the patient said he felt sick in his stomach first and had a rush of gas up to his brain and then he didn’t know anything. Combining these two points, the patient’s seizure started from a specific symptom and the EEG abnormality also started from a localization, so the result of the comparative analysis this patient should be a partial seizure secondary to a generalized seizure. The patient also had other tests such as CT, MRI and blood tests, etc. These results do not affect the diagnosis of epilepsy, but hopefully these clues will identify the cause of epilepsy. Not all abnormalities are causes of epilepsy. For example, if MRI reveals an enlarged occipital brain pool or a small cyst, whether this finding is the cause of epilepsy also needs to be carefully analyzed to see if these abnormalities are in the area where the patient’s symptoms should occur. Blood test results should also be analyzed. If a patient has a positive blood serologic test for cysticercosis, it does not necessarily mean that the cause of the patient’s epilepsy is cysticercosis, because the patient’s intestinal parasites can also have a positive serologic test for tapeworms. In order to clarify the true relationship between a positive serologic test and epilepsy, a test of the cerebrospinal fluid for cysticercosis is necessary. Finally, based on the diagnosis, it is important to estimate what the patient’s prognosis will be in the future and what treatment options will achieve the best outcome. The consequences of the same seizure type are completely different. For example, if a child has an aphasic seizure, there is no adverse effect on the child’s intelligence, and the treatment is also effective; on the other hand, atypical aphasic seizures are more difficult to control and have a negative impact on intelligence. The medication used for different seizure types is not exactly the same. The time it takes to make a diagnosis of epilepsy may be just a few minutes, but the doctor puts a lot of brain power into analyzing and thinking about it, and this reasoning process cannot be replaced by any computer.
