Techniques are provided for regulating the expression and clearance of proteins in neural tissue using electrical stimulation. The techniques may be used for treating and/or preventing neurodegenerative disorders such as Alzheimer's disease. The treatment involves implanting an electrode within the neural tissue of a human or animal subject, and using the electrode to deliver an electric current to the neural tissue. The voltage, pulse width, frequency, duration, and other parameters of the electrical stimulation may be controlled to provide different effects on protein expression and/or clearance. The position of the electrode may also be selected to control protein expression and/or clearance in a selected neural region.
