Central pontine myelinolysis sodium concentration. Three to five days later, a second phase of neurological manifestations occurs correlating with the onset of myelinolysis. Observable immediate precursors may include seizures, disturbed consciousness, gait changes, and decrease or cessation of respiratory function. The classical clinical presentation is the progressive development of spastic quadriparesis, pseudobulbar palsy, and emotional lability (pseudobulbar affect), with other more variable neurological features associated with brainstem damage. These result from a rapid myelinolysis of the corticobulbar and corticospinal tracts in the brainstem. The most common cause is overly rapid correction of low blood sodium levels (hyponatremia). Apart from rapid correction of hyponatraemia,
Serum protein electrophoresis blood serum (the fluid portion of the blood after the blood has clotted) is applied to an acetate membrane soaked in a liquid buffer., to a buffered agarose gel matrix, or into liquid in a capillary tube, and exposed to an electric current to separate the serum protein components into five major fractions by size and electrical charge: serum albumin, alpha-1 globulins, alpha-2 globulins, beta 1 and 2 globulins, and gamma globulins. Proteins are separated by both electrical forces and electroendoosmostic forces. The net charge on a protein is based on the sum charge of its amino acids, and the
