"WebThe asymmetry in the alpha wave is normal, but we notice increased amplitudes of the slow waves (delta, theta, and alpha) in the left hemisphere. The amplitudes of the SMR wave in C3 are 3.51 mV and in C4—3.27 mV, the difference in amplitudes is 20%, but the amplitude itself is lower than the norm. " - Generalized theta delta slowing causes

WebMedically intractable seizures appear to be highly correlated with focal slow activity (delta or theta). They also correlate highly with decreases in the coherence of theta. Normalization of focal slowing and of decreased theta coherence will probably be the neurofeedback approaches most likely to decrease or eliminate seizures in future cases. WebJul 11, 2011 · Some possible causes: migraine, seizure, stroke, hypoglycemia or hyperglycemia. When the neuro looks at the slowing, the main factor they consider is the speed of the wave.
