System and method for treating various neurological disorders using synchronized nerve activation

A method of neuromodulating treatment for Alzheimer's Disease (AD) or dementia in a patient, the method comprising:

• applying stimulation to a cranial nerve by at least one electrode of a cranial nerve stimulator of a neuromodulation system attached to a concha of an ear, thereby treating the AD or the dementia, wherein said applying comprises applying said stimulation to said cranial nerve by said at least one electrode attached to said concha of the ear and by at least one second electrode attached to a back of the ear.

A method of neuromodulating treatment for Alzheimer's Disease (AD) or dementia in a patient, the method comprising:

• applying stimulation to a cranial nerve by at least one electrode of a cranial nerve stimulator of a neuromodulation system attached to a concha of an ear, thereby treating the AD or the dementia, wherein said applying comprises applying said stimulation to said cranial nerve while said patient is asleep.

A method of neuromodulating treatment for Alzheimer's Disease (AD) or dementia in a patient, the method comprising:

• detecting that said patient is asleep;
• applying based on said detecting, stimulation to a cranial nerve by at least one electrode of a cranial nerve stimulator of a neuromodulation system attached to a concha of an ear, thereby treating the AD or the dementia, wherein said applying comprises applying said stimulation to said cranial nerve while said patient is asleep.
