Method of detecting cerebral stroke or asymptomatic cerebral infarction using acrolein, interleukin-6 and crp contents, polyamine oxidase activity or polyamine oxidase protein content and subject's age as indicators

A kit for detecting asymptomatic cerebral infarction in a subject, comprising;

• a reagent for measuring, in a biological sample obtained from the subject,
• (a) content of an aldehyde compound fowled from polyamine,
• (b) content of interleukin-6,
• (c) content of C-reactive protein, and
• (d) polyamine oxidase activity or content of polyamine oxidase protein;
• and
• an instruction on how to determining a likelihood of asymptomatic cerebral infarction in the subject based on the measured value of one or more of (a)-(e) and the age of the subject.

A system for detecting asymptomatic cerebral infarction in a subject, comprising:

• a reagent for measuring, in a biological sample obtained from the subject,
• (a) content of an aldehyde compound formed from polyamine,
• (b) content of interleukin-6,
• (c) content of C-reactive protein, or
• (d) polyamine oxidase activity or content of polyamine oxidase protein;
• a computer;
• and
• software for carrying out statistical analysis.
