Researchers at IBM and the Columbia University-psychotic disorder have developed a program of speech analysis to diagnose possible cases psychosis . A condition characterized by loss of coherent thought and lack of perception of reality.
Psychosis is a generic term used in psychiatry and psychology to refer to a state Mental described as a split or loss of touch with reality. About 1% of the population between the ages of 14 and 27 years is considered to be of high clinical risk for psychosis.
People experiencing psychosis may have hallucinations or delusions and can exhibit changes in their personality and disorganized thinking. These symptoms may be accompanied by unusual or bizarre behavior, as well as difficulty interacting socially and inability to perform activities of daily life.
For the development of the scientific program of IBM and Columbia came together to create a base of established patterns and meaningless phrases when a person talks for long periods.
The tests were performed in 34 subjects, most of them were male where They were asked to narrate indefinitely their subjective experiences, being his speech transcribed and analyzed by the computer in relation to their expression patterns, including the semantics (meaning) and syntax (structure).
The analysis established the semantic consistency of each patient (how well he or she developed in the subject), and the syntactic structure, as the length of the sentences and using words that link determining sentences.
“A clinical psychiatrist can intuitively recognize the symptoms of disorganized thoughts in a traditional interview, but the machine can increase what you hear when accurately measure variables “, referred to developers.
” The current detection method have a range of 70% efficiency. In tests, the software was able to have a 100% effective in detecting “.
Certainly an encouraging step forward, not only to patients who may suffer the disorder but for psychiatry in general, as a frequent criticism of this specialty is old and questionable validity of some of its instruments, jobs like these researchers are a connecting bridge between the computer and . psyche
Now the researchers hope to go further in future work addressing other disorders such as depression, obsessive compulsive disorder or autism
