The first study was a pilot study with people who suffer from mental illness at the Abarbanel Mental Health Center, Israel. The findings were published in the Israel Journal of Psychiatry in 1999. The aim of the study was to determine whether or not the hand features can reveal psychiatric diseases. It was based on the fact that many studies had found that minor physical anomalies (MPA) including some hand features, were associated with physical and mental problems. The results appear in my book: The Hand: The Mirror of the Soul.
