The symptoms are muscle weakness, slow reaction time, visual perception issues, seizures, hearing loss, weight gain, general sense of pain and delusions. Using the above scanning techniques, a doctor concluded that there are problems in emission of neurotransmitters and secretion of hormones as well as myelin sheath of some neurons, occipital lobe, and temporal lobe. Could you tell me how the doctor used the scanning tools to reach to his conclusion? I totally have no idea how the doctor learned that there's problem in emission of neurotransmitter by using scanning techniques.

You would have to ask your doctor to be certain but it seems to me that the PET could have identified the myelin sheath problems by the MeDAS binding and certainly could identify the neurotransmitters which were out of balance. The neurotransmitters are found by using a radiotracer which makes them measurable on the PET. The fMRI would have confirmed or identified the myelin sheath problems in a more localized way. The EEG was also given to rule out certain kinds of seizures and possibly identify the correct type.
T2 weighted MRI scans can reveal white matter lesions, so that may explain the detection of demyelination.
Of course, that's not fMRI...
