Chaologic brain function diagnosis apparatus

A chaos theoretical brain function diagnosis apparatus for diagnosing a brain function of a subject by giving a load to a functional site of a living organism of the subject, receiving a reaction emitted from the living organism of the subject as an electric signal, and analyzing the electric signal,

• wherein the apparatus selects at least two from among a voice signal, a nystagmus signal, a pulse wave signal and a gravity center swinging signal as the electric signal;
• calculates chaos theoretical indexes according to a chaos theoretical technique;
• detects changes in the chaos theoretical indexes with passage of time;
• and collectively evaluates and diagnoses the brain function, and
• wherein the chaos theoretical brain function diagnosis apparatus comprises:
• a nystagmus signal processor that divides the nystagmus signal, which is input from a nystagmus measuring instrument to the chaos theoretical brain function diagnosis apparatus and converted into a digital signal, into processing units, and removes data other than nystagmus data;
• a chaos theoretical index calculator that analyzes nystagmus data with data other than the nystagmus data removed in the nystagmus signal processor, by using a chaos theoretical technique, calculates a chaos theoretical index, and stores a calculation result of the chaos theoretical index in an evaluation and diagnosis database;
• and
• a chaos theoretical index change state detector that detects a change state of the chaos theoretical index by comparing the calculation result of the chaos theoretical index with a chaos theoretical index of the nystagmus signal of the same person at a different time point previously stored in the evaluation and diagnosis database.
