Alzheimer's disease is treated with an amphetamine compound. In one embodiment, the method includes administering an l-amphetamine compound. In another embodiment, the method includes administering an l-methamphetamine compound.
1 . A method of treating Alzheimer's disease in a human, comprising the step of administering an effective amount of an amphetamine to the human, wherein the amphetamine is administered as a component of a composition that includes amphetamine and, optionally, a methamphetamine, wherein at least about 85 mole percent of the total amphetamine and methamphetamine content of the composition is l-amphetamine.
2 . The method of claim 1 , wherein at least about 95 mole percent of the total amphetamine and methamphetamine content of the composition is l-amphetamine.
3 . The method of claim 1 , wherein memory is improved in the human following administration of the amphetamine.
4 . The method of claim 3 , wherein the improvement in memory is an improvement in at least one member selected from the group consisting of an improvement in short-term memory, long-term memory, memory consolidation, procedural memory and declarative memory.
5 . The method of claim 1 , wherein attention is improved in the human following administration of the amphetamine.
6 . The method of claim 1 , wherein executive function is improved in the human following administration of the amphetamine.
7 . The method of claim 1 , wherein reaction time is improved in the human following administration of the amphetamine.
8 . The method of claim 1 , wherein learning is improved in the human following administration of the amphetamine.
9 . A method of treating Alzheimer's disease in a human, comprising the step of administering an effective amount of an amphetamine to the human, wherein the amphetamine is administered as a component of a composition that includes amphetamine and, optionally, a methamphetamine, wherein at least about 85 mole percent of the total amphetamine and methamphetamine content of the composition is l-amphetamine and wherein the amphetamine is administered at a dose of at least about a 2 mg and about a 60 mg dose per day.
10 . A method of treating Alzheimer's disease in a human, comprising the step of orally administering an effective amount of an amphetamine to the human, wherein the amphetamine is administered as a component of a composition that includes amphetamine and, optionally, a methamphetamine, wherein at least about 95 mole percent of the total amphetamine and methamphetamine content of the composition is l-amphetamine and wherein the amphetamine is administered at a dose of at least about a 2 mg and about a 60 mg dose per day.
11 . A method of treating Alzheimer's disease in a human, comprising the step of orally administering an effective amount of amphetamine to the human, wherein the amphetamine is at least about 95 mole percent l-amphetamine relative to the total amphetamine content of the composition.
