chemical composition of IGF-I for the treatment and prevention of neurodegenerative diseases.

Chemical composition of IGF-I for the treatment and prevention of neurodegenerative diseases. The invention relates to the preparation and production of new chemical compositions slow administration of IGF-I. These compositions correspond to microspheres less than 5 micrometers size, among other characteristics, and subcutaneous implantation capsules. The present invention further describes the use of any such compositions in the preparation of medicaments for the treatment and prevention of neurodegenerative diseases such as, among others, Alzheimer's disease or cerebellar ataxia.
