TREATMENT OF DEGENERATIVE BRAIN DISORDERS USING TRANSCRANIAL MAGNETIC STIMULATION
Methods and systems for transcranial magnetic stimulation applied to the posterior cingulate including bundle fibers to treat Alzheimer's. Excitatory impulses from (or triggered by) the applied TMS may be transmitted through to the entorhinal cortex and hippocampus, which are early sites in which Alzheimer's disease begins to develop. Excitatory signals in the hippocampus and entorhinal cortex strengthen connectivity between cells, and increase. Overall metabolic activity may be increased, serving to help promote resistance to the Alzheimer's disease process and encouraging maturation and integration of neural stem cells native to this region of the brain.

applying a rapid TMS pulse pattern of at least 10 Hz from each of the plurality of TMS coils to drive stimulation of the patient's posterior cingulate for about thirty seconds or more; and
repeating the orienting and applying steps above for a plurality of treatment sessions.

7 . The method of claim 1 , wherein applying comprises independently applying pulsed TMS from each of two or more TMS coils oriented around a back region of the subject's head to evoke stimulation of the subject's posterior cingulate.
8 . The method of claim 1 , wherein applying comprises applying pulsed TMS at at least 10 Hz from each of three or more TMS coils oriented around a back region of the subject's head to neuromdulate the subject's posterior cingulate nerve fiber bundle until action potentials are propagated into the subject's entorhinal cortex and hippocampus to increase neuronal activity therein.
9 . The method of claim 1 , wherein positioning comprises locking two or more TMS coils into a position around a back of the subject's head to aim stimulation from the plurality of TMS coils to the subject's posterior cingulate nerve fiber bundle.
10 . The method of claim 1 , wherein applying the rapid TMS pulse pattern produces a net increase in metabolic activity in the subject's posterior cingulate fiber bundle.
11 . The method of claim 1 , wherein applying the rapid TMS pulse pattern produces an increase in metabolic activity in the temporal lobe.
12 . The method of claim 1 , wherein applying the rapid TMS pulse pattern from each of the plurality of TMS coils comprises applying a rapid TMS pulse pattern for between about one minute and 1 hour.
