What is a PSYCHOSIS?

A 'psychosis' or a 'psychotic' state of mind is: a sever psychological state of mind where the subject is not able discriminate the outside (objective) reality from the inside (subjective) reality1. Possible aspects of psychotic behavior are: delussions, hallucinations and thinking disorders. Genes may play a part in the onset of this kind of behavior. Table C-1 (see page 14) describes the various psychoses which are described in the DSM-IV system of classification.

The relationship between hand features and psychoses (other than schizophrenia) has been studied in a relative small number of studies. Nevertheless, these studies have produced results which appear to be related to schizophrenia.

LEVEL 1: the dermatoglyphics and psychotic behavior.

In a study executed by Hilbun2 the hands of 20 psychotic children had e.g. a relatively high number of fingerprint whorls. In a study executed by Markow & Gottesmann3 the hands of twins had frequently a different pattern on individual fingers of both hands.

The study of Hilbun2 describes a high frequency of a palmar loop between the middle finger and the ring finger. The axial triradius was more frequently observed in the lower parts of the palm, however the AtD-angle showed frequently a value above 56 degrees, see: table C-7 and figure C-8.

Table C-7: the AtD-angle in psychotic people.

- AtD-angle - Normal - Psychotic
- t - less than 450 - 63 % - 25 %
- t' - between 450 and 560 - 21 % - 10 %
- t'' - more than 560 - 2 % - 50 %
- tt' (= 2 triradii) - 6 % - 10 %
- Overige combinaties - 8 % - 5 %

Figure C-8: The AtD-angle = angle between the a- and d-triradius on the basis of the axial-triradius (t).
