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.
Prolactinoma - What else can cause elevated prolactin levels? There are a few conditions other than prolactinomas that may be associated with hyperprolactinemia. As prolactin is regulated by dopamine , medications that interfere with this substance in the brain can cause elevated prolactin levels. Drugs prescribed for psychiatric and gastrointestinal disorders may raise prolactin levels to greater than 200 ng/ ml.
