Too many ions inside a neuron cell. What happens?

For example, there are diseases where the sodium channel cannot gauge voltage difference effectively, and so it remains open, rapidly ... a concentration of sodium ions in the cell, and this disorder often affects potassium channels, so there is practically no way that the excess sodium ions ...
