APPLICATION OF FUZZY CLASSIFIER TO OBSESSIVE COMPULSIVE DISORDER (OCD) IDENTIFICATION AND PROGNOSIS
DOI: 10.5987/UJ-NJSE.16.015.2 | Article Number: D679A715 | Vol.12 (2) - September 2013

Keywords: Fuzzy classifier, fuzzy logic, fuzzy set, diagnosis, OCD
Many of us occasionally have to go back and double-check that an iron is unplugged or the car
door is locked. However for sufferers of obsessive-compulsive disorder (OCD), obsessive thoughts
and compulsive behaviors become so excessive that they interfere with their daily lives. The persistent
thought associated with OCD often lingers unnecessarily. Family history, chemical imbalances
in the brain, specific chromosome/gene variation and some life stressors; like being the victim
of sexual abuse as a child are thought to contribute to the development of the disorder. Symptoms
of OCD are characterized by ritual feelings, repeated hand washing, repeated touching, repeated
counting, repeated checking, rearranging things, anxious thoughts, frequent thoughts of violence,
fear of causing harm, unwelcome sexual thoughts and fantasies. In this paper, the traditional
procedure of the medical diagnosis and prognosis of OCD employed by physicians is expressed
using Fuzzy classifier. The proposed expert system eliminates uncertainty and imprecise diagnosis
of OCD.
