Hand cramping can occur for many reasons and cause significant discomfort in some people. Often, hand cramps are caused by muscle spasms, which are described as an uncontrollable or involuntary muscle contraction. These spasms or contractions do not allow the muscle to become relaxed and can become excruciating in some cases.
Serum levels of prolactin may increase as a consequence of epileptic seizures. The hormone release is caused by the propagation of epileptic activity, usually from the temporal lobe to the hypothalamic-pituitary axis.
High serum prolactin concentrations inhibit secretion of gonadotropin-releasing hormone (GnRH) from the hypothalamus, thereby decreasing the secretion of gonadotropins (luteinizing hormone and follicle-stimulating hormone), and may also inhibit the action of gonadotropins on the gonads.
