As a treatment in Alzheimer's disease, Deprenyl studies showed improvement in attention and memory. Deprenyl slows the breakdown of neurotransmitters in the brain and increases the release of dopamine. There has been much research and literature in the past few years about the broad spectrum of aging related symptoms which Deprenyl can treat successfully.
Dosage: For Alzheimer's patients 10 mg per day. For depression 5-10 mg per day with 500mg of l-phenylalanine. Other uses for life-extension 1-5 mg per day depending on age.
Precautions: At lower dosages, there seems to be no precaution required. There is some interaction with MAO inhibitors at extremely high (50-60mg) doses.
