The medical community is currently still uncertain of the actual causes of phobias. However, there are many theories which attempt to explain the possible causes. These include, for example, an internal conflict within one’s conscience, prior negative experiences with the object of their fear, or a chemical imbalance in the brain. Another cause may be related to a person’s genetic makeup, owing to findings that suggest people who suffer from phobias are likely to have family who also suffer from phobias.
Nonetheless, these causes may only go so far in explaining why some sufferers experience phobias. There are, as of yet, no sure clinical techniques available that can be used to assess the causes of all types of phobias.
