I have been treated for depression for over ten years and have had various diagnoses from bipolar disorder, OCD to personality disorders. I have tried over thirty medications with little benefit. Thanks for the question Jackie. Encephalomalacia refers to scaring of the brain and can be due to a number of abnormalities - vascular problems being one. It is really a non-specific term to denote an area of previous injury.
Demyelination refers to scaring related to abnoralities of myelin in the brain.
This can be caused by a number of disease processes including multiple sclerosis and viruses. The Temporal lobe, however, is not a common area for demyelinating lesions. I am concerned, however, that the previous EMG revealed sharp wave discharges. We have a world renowned epilepsy department that has as one of its major interests temporal lobe abnormalities that cause seizures. This information is provided for general education purposes only.
