Hydergine is used to treat age-related brain disorders such as memory loss or difficulty concentrating. It is believed that the drug helps improve blood flow to the brain, which enhances cognitive functions and reduces symptoms associated with certain types of dementia.
Hydergine may also be used in some cases to treat orthostatic hypotension or balance problems. However, it should only be used under medical supervision due to its potential effects and compatibility with the patient's health condition.
