Judith, like her mother, father, sister and brother, suffered from familial tremors. Tremors, as explained by the National Institute of Neurological Disorders and Stroke (NINDS), are unintentional, rhythmic muscle movements that involve to-and-fro movements of one or more body parts
Judith Perretta, who recently underwent a deep brain stimulation procedure at Northeast Georgia Medical Center, can now enjoy activities with her friends, such as dessert and coffee, without worrying about her familial tremors.
