Lisdexamfetamine is primarily helpful for the treatment of ADHD (attention deficit hyperactivity disorder) and binge eating disorder. It has similar pharmaceutical effects like amphetamines. Vyvanse is not recommendable for individuals above 65 years of age. In individuals with ADHD, Vyvanse improves brain development and nerve growth. Reviews of MRI studies suggest that Vyvanse long-term treatment can decrease brain structure abnormalities in people with ADHD and improves the functioning of several parts of the brain such as the basal ganglia’s right caudate nucleus. It is a medication that is useful for the long-term treatment of attention deficit hyperactivity disorder.

Although Vyvanse helps treat moderate to severe Binge Eating Disorder (BED), It is not advisable to use the medicine for weight loss. The use of sympathomimetic drugs such as Vyvanse for weight loss results in severe adverse cardiovascular effects. There is no establishment of the safety and effectiveness of medicine for obesity treatment or weight loss.
