Systems and methods for the identification of medical conditions, and determination of appropriate therapies, by passively detecting acoustic signals from cerebral vasculature

A method for determining if a patient is suffering from a condition, the method comprising:

• positioning at least one microphone, acoustic sensor, or accelerometer within a first predefined distance of at least one of the patient's basilar artery, anterior inferior cerebellar artery, anterior vestibular artery, internal auditory artery, common cochlear artery, internal carotid artery, or ophthalmic artery and outside of a second predefined distance from at least one of the patient's zygoma, external carotid artery, internal maxillary artery, facial artery, or occipital artery, wherein the first predefined distance is less than the second predefined distance;
• capturing a signal transduced through a medium, wherein the medium is at least one of air, tissue, bone, vasculature, or nerves, wherein the signal is caused by blood flow in a cerebral vasculature of the patient's brain and is not a function of a second signal originating external to the patient, and wherein the signal is captured using at least one of the accelerometer, the acoustic sensor, or the microphone;
• digitizing the captured signal using a first component in data communication with the accelerometer, acoustic sensor, or microphone;
• transmitting the digitized captured signal to a signal analyzer using a second component in data communication with the first component;
• using the signal analyzer, acquiring the digitized captured signal and processing the acquired digitized captured signal to identify a signature, wherein the signature is a function of a non-zero amplitude, frequency and periodicity of the signal, wherein the signature is uniquely indicative of the condition, and wherein the condition is one of a tension headache, a migraine, vascular dementia, Alzheimer's disease, epilepsy, vascular Parkinson's disease, cerebral vasospasm or meningitis;
• and
• using a computing device, receiving the signature, comparing the signature to one of a plurality of predefined patterns indicative of the condition, and categorizing the signature as being representative of the condition, wherein the plurality of predefined patterns includes acoustic signal data indicative of a plurality of different migraine types.
