Its temporal lobe dysfunction. Sensory input (hearing, seeing, feeling) is routed to the temporal lobe of the brain. The temporal lobe analyzes by referencing memory and providing emotional context to your inputs.
The temporal lobe is said to be "extremely prone to insult". Psychoactive drugs can insult the temporal lobe. Excessive amplitude of sensory input can stress the temporal lobe. (PTSD). Emotional abuse
insults the temporal lobe. The temporal lobe is also said to be the seat of an individual's soul. An insult to the temporal lobe can be like an insult to your soul. Loss of emotions. Loss of personality.
I write from experience and from my research. I lost my emotions following a sequence of temporal lobe seizures at age 17. A description of my epileptic syndrome describes me as a worst case scenario.
My "post ictal psychosis segued into an affective disorder of a recurrent major depressive disorder." A lesser symptom of my illness was temporary DR and long term DP.
It took 40 years to solve the riddle of my illness. Neurology, psychiatry, and the medical community in general were worthless in helping me. I discovered the appropriate diagnosis for myself
following research into British Neurological Journals after googling into a medical library. I followed up with an MRI and EEG which confirmed my self diagnosis. My EEGs show significant pathology in my
temporal lobe, consistent with a history of epileptic seizure. Sadly, all neurology could say....even after
40 years...was that I was disabled and entitled to social security disability payments. And, they are a welcome addition to my pension as I did not allow my illness to disable me.
I also suffered frequent ocular migraines from the age of 17. That was also due to my temporal lobe dysfunction and it is all related. A neurologist explained the ocular migraines and said "WE (US Neurology) have
"Bigger Fish to Fry". He then noted the Brits had done more research into that area. Well, that proved helpful in my future search for answers. But, today (thanks to the Brits), neurology understands the
nexus between migraine and epilepsy. "Migraine, the borderlands of Epilepsy" is the title of a recent research paper. My local Epilepsy Center also treats migraine. Temporal lobe epilepsy is the most common
form of the illness and it is all pathology in the temporal lobe.
If I ever write a book about my life, I will have to title it "Bigger Fish to Fry".
