A specific clinical protocol for use toward therapy of defective, diseased and damaged cholinergic neurons in the mammalian brain, of particular usefulness for treatment of neurodegenerative conditions such as Alzheimer's disease. The protocol is practiced by delivering a definite concentration of recombinant neurotrophin into, or within close proximity of, identified defective, diseased or damaged brain cells. Using a viral vector, the concentration of neurotrophin delivered as part of a neurotrophic composition varies from 10<10 >to 10<15 >neurotrophin encoding viral particles / ml of composition fluid. Each delivery site receives from 2.5 mul to 25 mul of neurotrophic composition, delivered slowly, as in over a period of time ranging upwards of 10 minutes / delivery site. Each delivery site is at, or within 500 mum of, a targeted cell, and no more than about 10 mm from another delivery site. Stable in situ neurotrophin expression can be achieved for 12 months, or longer.

The invention provides a specific protocol for use in grafting donor cells genetically modified to produce nerve growth factors into grafting sites within the cholinergic basal forebrain and is especially useful in treating neurodegenerative conditions such as Alzheimer's Disease. Grafting sites are selected for proximity to previously identified defective, diseased or damaged brain cells.
