Exposing the cause can diminish the anxiety associated with the fear by taking it out of the unknown so that rational suggestions can be used to alleviate symptoms. Once the causes are revealed, the technique of systematic desensitization may be the treatment of choice. Systematic desensitization is a well organized procedure to bring the psyche back into balance, eliminating the fears by hypnotic confrontation. The fears are met and faced through the subconscious mind. Repeated confrontation causes deterioration of the fear symptoms and increases the ability to face and deal with past traumatic experiences without apprehension, which the conscious mind then accepts.
Age regression can also be a highly effective technique for uncovering causes.
