Delusional disorder is a condition with non bizarre delusions; beliefs that can occur in real life; for
instance being poisoned, being watched, being deceived, or having an illness, These
delusions do not include other symptoms of schizophrenia or other disorders
where delusions can occur. These delusions may seem believable, and the person
may appear normal. These delusions are
not due to a medical condition or substance abuse.
The delusions are of different
types: a type where the person believes
that a person, usually of higher social standing, is in love with the
individual; grandiose type the person believes
that he has some great but unrecognized talent or insight, a special identity,
knowledge, power, self-worth, or special relationship with someone famous or
with God; jealous type the belief that his partner has been unfaithful;
persecutory type the individual believes he is being cheated, spied on,
drugged, followed, slandered, or somehow mistreated; somatic type where there
is an experience of physical sensations or tactical; such as foul odors or
insects crawling on or under the skin or he is suffering from a general medical
condition or defect; mixed type more than one of the type of delusion. Delusions also
occur as symptoms of many other mental disorders, especially the other psychotic
disorders.
The cause of delusion disorders
is not know however researchers find certain features indicate that when
delusional disorders occur later in life they may be hereditary. Early childhood experiences
may be a contributing factor. Some
researchers propose that any person with a sensitive personality is vulnerable
to developing a delusional disorder.
Treatment of delusional disorders is drug therapy and psychotherapy. Treatment is complicated, for many reasons,
such as the patient's denial that they have a psychological problem.
Antipsychotic medications are
used in the treatment of delusional disorder as well as in schizophrenic
disorders. These medications work by reducing the incidence of psychotic
symptoms; hallucinations and delusions. They also alleviate the anxiety
and agitation.
Psychotherapy for patients with
delusional disorder includes cognitive therapy. Psychotherapy has been
said to be an effective form of treatment.
