The aim of this study was to analyze the differences between the handwritings of schizophrenia patients and healthy subjects in addition to the changes that occurred in schizophrenia patients' handwriting in response to the treatment. The test subjects were 29 schizophrenia patients and 29 healthy individuals with the same age, gender, and dominant hand. The changes in the handwritings were examined according to 14 different parameters. On the day of admittance, the percentage of extra letters was 16.7%, and after 7-10 days of hospitalization, it rose to 33.3%. The percentage of skipped words decreased from 29.2% to 16.7% after 7-10 days of hospitalization, and to 10% after 3 weeks. The letters written by schizophrenia patients are significantly larger in height and width compared to the control group. The schizophrenia patients showed a higher incidence of crossed-out letters, adding extra words, missing punctuation as well as missing words.
