1. A method of diagnosing cerebral infarction, comprising the steps of:

  • obtaining a set of teaching data on each subject in a group of health subjects and subjects of cerebral infarction, each said teaching data set comprising an age of said subject, measurement of at least one coagulo-fibrinolytic molecular marker for said subject, and an index indicative of cerebral infarction for said subject;

    modifying each said measurement of coagulo-fibrinolytic molecular marker in said teaching data in order to cause said measurements to be independent of age;

    inputting each set of the modified teaching data into a neural network for use in diagnosing patients and making said neural network learn said teaching data;

    obtaining a set of testing data on a patient to be diagnosed, said testing data comprising an age of said patient and measurement of said at least one coagulo-fibrinolytic molecular marker for said patient;

    modifying each said measurement of coagulo-fibrinolytic molecular marker in said testing data in order to cause said measurements to be independent of age for purposes of said diagnosing;

    inputting the modified testing data into said neural network and obtaining therefrom, as a diagnostic output for said patient, an index indicative of cerebral infarction which is specific to said patient; and

    diagnosing cerebral infarction in said patient from said index.
