Abstract
Techniques are described for determining cognitive impairment, an example of which includes accessing a set of epochs of magnetoencephalography (MEG) data of responses of a brain of a test patient to a plurality of auditory stimulus events; processing the set of epochs to identify parameter values one or more of which is based on information from the individual epochs without averaging or otherwise collapsing the epoch data. The parameter values are input into a model that is trained based on the parameters to determine whether the test patient is cognitively impaired.
Claims20
A method comprising:
- accessing a set of epochs of electrical data of responses of a brain of a test patient to a plurality of auditory stimulus events;
- identifying different types of peaks in the set of epochs, the different types of peaks including at least a first type of peaks;
- selecting a subset of epochs that are identified as having the first type of peaks;
- determining a plurality of parameter values by analyzing individual epochs of the electrical data,
- at least first parameter values determined based on epochs captured by an electrical sensor that is located ipsilateral to where the auditory stimulus events occurred on the test patient;
- at least second parameter values determined based on epochs captured by an additional electrical sensor that is located contralateral to where the auditory stimulus events occurred on the test patient;
- and
- at least the first parameter values or the second parameter values determined from the subset of epochs that are identified as having the first type of peaks;
- inputting the parameter values into a model that is trained based on the parameters;
- and
- providing a determination as to whether the test patient is cognitively impaired based on the plurality of parameter values.
A computer system comprising:
- a computer processor;
- a memory storing a set of instructions that when executed by the computer processor causes the computer processor to:
- access a set of epochs of electrical data of responses of a brain of a test patient to a plurality of auditory stimulus events;
- identify different types of peaks in the set of epochs, the different types of peaks including at least a first type of peaks;
- select a subset of epochs that are identified as having the first type of peaks;
- determine a plurality of parameter values by analyzing the epochs of the electrical data,
- at least first parameter values determined based on epochs captured by an electrical sensor that is located ipsilateral to where the auditory stimulus events occurred on the test patient;
- at least second parameter values determined based on epochs captured by an additional electrical sensor that is located contralateral to where the auditory stimulus events occurred on the test patient;
- and
- at least the first parameter values or the second parameter values determined from the subset of epochs that are identified as having the first type of peaks;
- and
- inputting the parameter values into a model that is trained based on the parameters;
- and
- provide a determination as to whether the test patient is cognitively impaired based on the plurality of parameter values.
