A seizure disorder or Epilepsy are used interchangeably. Epilepsy/Seizure disorder are two or more unprovoked seizures caused by abnormal electrical activity in the brain. Back when I was diagnosed eons ago by my then primary and two days later by a Neurosurgeon as having Epilepsy but only had one seizure. Somewhere along the line they decided you needed to have two unprovoked seizures for that diagnosis. Terminology has changed, for example, when I was diagnosed, my seizures were called major motor seizures, later, they were called grandmal and now are Tonic-Clonic. I wonder if seizure disorder had a different meaning at one time. Perhaps if seizures were/are provoked by certain illnesses were/are considered a seizure disorder.
As far as the “very loud noise” is concerned it may have been what’s known as the Epileptic cry. It happens during the tonic phase of a seizure when powerful contractions squeezes the air out of the lungs and the vocalization is made as the air rushes past the vocal cords.
It’s usually short and loud.”
Most strokes are caused by a blockage usually a clot (ischemic stroke) causing lack of blood and oxygen that causes brain cells/tissue to die. High blood pressure is also a cause. There are also hemorrhagic strokes when a blood vessel ruptures.
Atrophy is common especially in older folks. The rear part of your brain is the occipital lobe, seizures originating there are uncommon. You should get more information about the atrophy. Are you having any problems speaking, writing or other issues?
