Does blocking the NA channels have similar behavioral effects than blocking the CA channels.

It depends where you block Na/Ca channels in the body. The physiology of the hohle system is very complicated. In the kidneys it would cause diuresis. In the gastrointestinal tract it would hamper resorption of substances and water. In the brain. In the heart it would block fast Na channels and therefore changing timing of action potential. Na and Ca are essential metals also in the propagation of actionpotential in dendrites, axones. Ca is also trigger of muscle contraction (sarcoplasmatic reticulum) and plays an important role in releasing neurotransmitters in synapses. Blocking na/ca directly would cause tremendous side effects.
Na/ca plays an essential role in the brain.
But it is only partly understood.

I have noticed that a lot of anti-convulsants work on CA and NA in the brain.
I just recently got a hair analysis done and it showed low lithium levels and four times the amount of calcium and magnesium than is usually seen in hair samples. However, I don't know if hair samples correlate with what is in your blood serum, or in your brain.
I have not been dx'd as bipolar (felt great on paxil for many years until I went through horrible withdrawal--now, nothing seems to work or I can't tolerate it), but it made me wonder. Does anyone know if people with bipolar have too much calcium?
