What Is Contamination OCD Signs, Symptoms And Why It’s More Than Just Being Clean
Contamination OCD is a variation of Obsessive Compulsive Disorder OCD, which extends well beyond likability to keeping things clean. Although most people like clean environments, patients who have contamination OCD have overpowering, intrusive phobias directed at germs, dirt, disease, or toxic substances. Such fears are also not one time or short lived, but overwhelming and hard to contain, and they tend to disrupt everyday life, personal relationships, and performance.
Contamination OCD consists of the belief that one may be contaminated or may contaminate others. These obsessions cause intense anxiety, thus resulting in compulsions with an object of alleviating distress. These thoughts are recurrent and uncontrollable as opposed to normal thoughts that are concerned with hygiene.
A person with contamination OCD will be afraid of touching door handles, sitting on public transportation, or even cash. The fear cannot be easily relieved and it tends to increase unless the individual undertakes some rituals.
It is important to identify symptoms of contamination OCD to intervene early.
Some common signs include:
One of the major distinctions between cleanliness and contamination OCD is distress and dysfunction. When a person is just obsessed with cleanliness, he gets satisfaction after cleaning. It is hard to find a person with contamination OCD who does not feel relieved. Rather, they experience unceasing uncertainty, such as, did I wash well enough, might there be still some germs, which results in repetitive behaviour.
The situation is based on anxiety rather than preference. The fear is usually catastrophic, like thinking that one can get a serious disease by touching a surface or even hurt his or her loved ones. This is a continual alertness which may affect the mental health, leading to exhaustion, irritability and withdrawal.
Similar to other types of Obsessive Compulsive Disorders, contamination OCD can be caused by a complex of genetic, neurological, and environmental factors. Vulnerability can be enhanced by stressful events in life, a family history of anxiety disorders or traumatic experience. According to brain imaging research, some brain circuits associated with fear and decision-making could work differently on people with OCD.
When fears of germs or contamination are taking over an hour or more a day, distressing or interfering with normal life, it is possible to seek the help of a professional. Early treatment and diagnosis is one of the key elements that can improve the outcome. Contamination OCD is not concerned with being too clean or being overprotective. It is a severe mental illness that should be understood, be empathetic and treated with evidence based care.
