Overview. Dehydroepiandrosterone (DHEA) is a hormone produced by the body's adrenal glands. The body uses DHEA to make androgens and estrogens, the male and female sex hormones. DHEA levels peak at about age 25, then go down steadily as you get older. By the time people are 70 to 80 years old, their DHEA levels are only 10 to 20% those in young adults.
The Psychotic Symptom Rating Scales (Haddock et al., 1999) are semi-structured interviews designed to assess the subjective characteristics of hallucinations and delusions (see Appendix).
Two of the most common symptoms of psychotic disorders are hallucinations -- the experience of images or sounds that are not real, such as hearing voices -- and delusions, which are false fixed beliefs that the ill person accepts as true, despite evidence to the contrary.
