Case 1 :
Miss x is a 31 years old secretary who has always been a clean and tidy person. For the past 3 months, however, she has been excessively fearful of getting contaminated by “germs”. She spends a several minutes each time washing her hands with soap whenever she touched a surface which she deemed as “contaminated” eg. An office document, a chair and most other surfaces. She is starting to develop redness and peeling of her hands because of excessive washing. At home, she can only sleep very late as she has to spend many hours cleaning her house. Her relationship with her boyfriend suffers as she finds kissing and even holding hands unhygienic and “dirty”. She becomes depressed as a result.
In obsessive doubt, a sufferer may have a persistent fear of having missed various things (such as not properly switching off lights or gas stove, not closing doors or windows properly, making a careless mistake in work or misplacing a wallet). He or she then compulsively checks for these “mistakes”. Hence the sufferer may spend a long time checking these things.
Case 2 :
Mr x is a 26 year old engineer who has become increasingly “stressed” by the need to check and double check items at home and work. Before leaving home for work, he will spend 30 minutes or even longer ensuring that all switches and taps are turned off. He has developed a time-consuming ritual of turning on and off a tap several times, then staring at it for 1 minute to ensure that it is properly turned off. On many occasions as he starts to drive to work, he will suddenly return home to repeat all the checks as he is doubtful if the checks are properly done previously. As a result he is frequently late for work. Besides chiding him for lateness, his boss also complains that he has not been submitting his work on time. Indeed, his compulsive checking and rechecking of all documents and papers because of his fears that he might make careless mistakes has delayed his work significantly and his colleagues has started to brand him as “slow”.
There is also a group of OCD sufferers who predominantly has repetitive and intrusive thoughts and mental images that keep replaying in their minds, for example of sex, violence, silly or senseless things that is abhorrent and has no relevance at all to the sufferer.
Case 3 :
Ms x is a 21 year old undergraduate studying Accountancy, who has been distressed for the past few weeks by some disturbing thoughts. She has thoughts of slapping her friends (for no reason) when they study together and also has mental images of them indulging in sexual acts. She finds these thoughts and images to be repulsive and disturbing, but they continued to be intrusive and difficult to resist. She is even more distressed when she goes for her regular prayers: she will have sudden impulses to blaspheme the name of God. She is afraid that she might lose control one day and shout blasphemies in public.
