Abstract: The present invention provides a method of delivering a treatment to the central nervous system, including the steps of administering a therapeutic intramuscularly into muscles innervated by nerves chosen from the group consisting of cranial nerves and spinal nerves, and transporting the therapeutic peripherally through nerves into the CNS and to the site of treatment. The present invention provides a method of treating a neural disorder or a part of the body by administering an effective amount of a compound affecting neural cells into muscles innervated by cranial and/or spinal nerves, and affecting neural cells. The present invention also provides a method of treating a spinal cord injury by administering an effective amount of a compound affecting neural cells into musculature directly innervated by the spinal cord, and affecting neural cells.

Abstract: A method for differentiating cognitively normal elderly individuals from mildly demented patients with Alzheimer's disease by monitoring motor/psychomotor test results by the use of various computer monitored transducer apparatus attached to the individual while the individual undergoes testing. Head tracking ability, head steadiness, EMG-Arm extension tracking, and joint position matching are measured parameters used in the method.
