Obsessions kuwukuphazamiseka kwengqondo. Zibonakala ngezithombe eziphazamisayo ezivela ngokuphindaphindiwe futhi okunzima ukuzisusa engqondweni. Zingahlotshaniswa nezindikimba ezehlukene ezinjengokungcola, ukungcoliswa, ukuhlambalaza, ubulili noma isiyaluyalu.

Ngezinye izikhathi okubizwa ngokuthi “imibono egxilile” noma “i-obsessive neurosis,” ukukhathazeka kuyaphazamisa, akujabulisi futhi akwamukeleki kumuntu obhekene nakho.

Kunezinhlobo ezintathu: imiqondo ecatshangelwayo (= imibono, ukungabaza, ukungabaza), i-phobic obsessions (= ukwesaba okuxakile) kanye nokuthatheka okungalindelekile (= ukwesaba ukwenza isenzo sobugebengu noma esiyingozi).

Abantu abanezinkanuko ngokuvamile bayayibona imvelo engalingani yemicabango yabo. Izimpawu zokuqala ze-obsessive neurosis ngokuvamile zivela cishe eminyakeni engama-20.

Kunezizathu ezehlukene ezingabangela i-obsessions:

• Izici ezingokwengqondo nezenhlalo (ukuhlukumezeka okwenzeka ebuntwaneni, izimo ezinzima zempilo, njll.) zingadala ukuthatheka.
• Kungase kuhileleke izici zofuzo. Izakhi zofuzo ezisiza ukulawula i-serotonin (= i-brain chemical messenger edlulisa amasignali phakathi kwamangqamuzana obuchopho) zingasakazwa.
• Ukuphazamiseka kwe-Metabolic ebuchosheni kungakhuthaza ukuqala kokukhathazeka ngenxa yokugcwala okunganele kwe-serotonin edlala indima ekulawulweni kwemizwa, ulaka, umfutho, ukulala, isifiso sokudla, izinga lokushisa lomzimba kanye nobuhlungu.
• Ezimweni zezinguquko emsebenzini wobuchopho, izifunda ezingu-3 zobuchopho zingase zibe nomsebenzi ophakeme kunokuvamile (i-orbito-prefrontal cortex, i-caudate nucleus, ne-corpus callosum) futhi ingaholela ku-neurosis ecindezelayo.

Ukukhathazeka isikhathi eside kungaholela ku-Obsessive-Compulsive Disorder (OCD). Kuwukusabela kokuziphatha emibonweni, ukuphoqelelwa kanye nokuphikisana nentando yomuntu obhekana nakho.

Ukukhathazeka kungaziveza kubantu abanokuthatheka ngoba bayazi ukuthi banemibono eqondile kodwa akukho abangakwenza ngakho.

Kwabanye abantu, ukuthatheka kuholela enkolelweni yokuthi ukucabangela okuthile kwandisa ingozi yokuthi kwenzeke, okuyinto  kungaba nemingcele kakhulu.

Ukuze ugweme ukuthatheka, kuhle ukugwema izinto ezivuselelayo ezifana notshwala, ikhofi noma ugwayi. Ukuzivocavoca umzimba kunconywa kanye nokuphumula.

Eminye imithi inganciphisa ukuqala kokukhathazeka ngokubonana nodokotela kuqala.

Ukwelashwa kweqembu noma imikhiqizo yezempilo yemvelo kungapholisa futhi kunciphise ukuthatheka.
