Ultra Wellness Center wanted to know more. The age of onset suggests the involvement of brain immaturity phenomena at the base of the phenomenon.

Several authors postulated that an imbalance in the production of neurotransmitters in the brain stem may cause hypsarrhythmia and epileptic seizures (by increasing serotonin or adrenergic systems, or by inhibition of the cholinergic system.) This theory is based on reducing the duration of REM sleep in these patients, coinciding with periods of decrease in the pattern of hypsarrhythmia and a lower frequency of spasms.Several studies with positron emission tomography cerebral blood flow and the influence of support structures or abnormal cortical signals in the development of the painting.
