My loss of consciousness is precipitated by a paroxysmal discharge of neurons from a focus in the cortex of my occipital lobe. Linked to the spinal cord, this misfiring of neurons fires other neurons thoughout my brain. Axons in my spinal cord controlling muscle activity fire abnormally, causing disordered contractions of muscles, especially those in the face, hands, and feet.
The first phase of the
seizure is the contraction phase-- my body becomes rigid, respiratory
and jaw
muscles contract, and oxygen supply in the blood is rapidly depleted
so my skin
turns a dusky blue color.
After one or two minutes, the
seizure
passes into its convulsive phase, with rhythmic movement of limbs and
trunk muscles.
These cease after a few
minutes, color returns, breathing regulates, consciousness returns
gradually. Normal movements of swallowing are lost, perhaps
there's some saliva dribbling from between my tightly clenched teeth.
Disordered contraction of bladder muscles could cause incontinence.
