The invention involves the formation of a prodrug from a fatty acid carrier and a neuroactive drug. The prodrug is stable in the environment of both the stomach and the bloodstream and may be delivered by ingestion. The prodrug passes readily through the blood brain barrier. Once in the central nervous system, the prodrug is hydrolyzed into the fatty acid carrier and the drug to release the drug.
In a preferred embodiment, the carrier is 4, 7, 10, 13, 16, 19 docosahexa-enoic acid and the drug is dopamine. Both are normal components of the central nervous system. The covalent bond between the drug and the carrier preferably is an amide bond, which bond may survive the conditions in the stomach. Thus, the prodrug may be ingested and will not be hydrolyzed completely into the carrier molecule and drug molecule in the stomach.

A method of treating Mild Cognitive Impairment has been discovered. The treatment method comprises administering an effective amount of a serotonergic agent, including, but not limited to dexnorfenfluramine. The agent can be any serotonergic agonist, partial agonist, serotonin reuptake inhibitor, or combinations of these agents. The treatment method also encompasses combinations of serotonergic agents and non-steroidal anti-inflammatory agents. The treatment method may also delay the onset of Mild Cognitive Impairment, dementia, or both.
