Some physicians prescribe "off label" medications for forms of memory loss other than dementia and Alzheimer's disease. "Off-label" means the medication has not been approved by the FDA for other types of memory loss, but the physician is prescribing it with the expectation of reducing symptoms.
The FDA has approved certain medications for mild to moderate Alzheimer's. These are called cholinesterase inhibitors. You may have seen these medications advertized on television or in magazines. One of the first to come on the market was Aricept® (donepezil). My clinical experience with this medication has been positive, in that I have seen patients experience improvement of symptoms on this medication.
Other memory loss medications approved for mild to moderate Alzheimer’s disease include Razadyne® (galantamine), Exelon® (rivastigmine), and Cognex® (tacrine). Cognex is rarely prescribed today due to safety concerns.
