and believe that certain individuals, or people in general, are "out to get them." Paranoid perceptions and behavior may appear as features of a number of
mental illnesses, including
and dementia, but are most prominent in three types of psychological disorders: paranoid schizophrenia, persecutory delusional disorder (persecutory type), and paranoid
personality disorder (PPD). Individuals with paranoid schizophrenia and persecutory delusional disorder experience what is known as persecutory delusions: an irrational, yet unshakable,
belief that someone is plotting against them. Persecutory delusions in paranoid schizophrenia are bizarre, sometimes grandiose, and often accompanied by auditory
Delusions experience by individuals with persecutory delusional disorder are more plausible than those experienced by individuals who are paranoid schizophrenic; not bizarre, though still
unjustified. Individuals with persecutory delusional disorder may seem offbeat or quirky rather than mentally ill, and, as such, may never seek treatment. Persons with paranoid personality
disorder tend to be self-centered, self-important, defensive, and emotionally distant. Their paranoia manifests in constant suspicions rather than full-blown delusions. The disorder often
impedes social and personal relationships and career advancement. Some individuals with PPD are described as "litigious," as they are constantly initiating frivolous law suits. PPD is more

schizophrenia. It
is a very serious lifelong condition, which may lead to complications such as
suicidal behavior.

information, work with the child at home to meet
IEP or IFSP goals, and give written consent for any evaluation or changes in placement. Professionals should value parents and build a

pervasive developmental disorder (PDD) -- Clinically described disorder in which autism is included, characterized by severe and pervasive impairment in several areas of development:
reciprocal social interaction skills, communication skills, the presence of stereotyped behavior, interest, and activities, abnormal social relations, bizarre mannerisms, inappropriate social
behavior, and unusual or
delayed speech and language.

pervasive developmental disorder, not otherwise specified (PDD-NOS) -- Subthreshold condition in which some -- but not all -- features of autism or another explicitly identified
Pervasive Developmental Disorder are identified. Also called atypical personality development, atypical PDD, or atypical
autism; marked impairment of social interaction, communication
and/or stereotypical behavior patterns or interest, but when full features for autism or another explicitly identified PDD are not met. According to the
DSM-IV, this category should be used
"when there is a severe and pervasive impairment in the development of social interaction or verbal and nonverbal communication skills, or when stereotyped behavior, interests, and
activities are present, but the criteria are not met for a specific Pervasive Developmental Disorder,
Schizophrenia, Schizotypal Personality Disorder, or Avoidant Personality
Disorder." However, the DSM-IV framework has not offered specific techniques or criteria for diagnosing PDD-NOS. Currently, no objective biological test, such as a blood test or an X-ray
examination, can confirm PDD-NOS. Diagnosing PDD-NOS is complicated and much like putting together a jigsaw puzzle that does not have a clear border and picture. Therefore it is
reasonable to say that, when a diagnosis of PDD-NOS is made, it reflects the clinician's best guess. Obtaining an accurate diagnosis requires an assessment conducted by a well-trained
professional who specializes in developmental disorders, usually a child psychiatrist, developmental pediatrician, pediatric neurologist, child psychologist, developmental psychologist, or

phobias -
Fears that result in excessive and unrealistic anxiety about everyday happenings. Exposure to the feared object
provokes an anxiety reaction. The anxiety and discomfort is out of proportion to the real threat of the feared object. The person
may experience excessive sweating, poor muscle control, or rapid heart rate. He/she may avoid situations in which contact with
the feared thing may occur. This may interfere with job and social functioning. The person may feel weak or cowardly and lose

psychosexual development -- Freud's stage theory of development, based on how the libido is transformed into different structures and modes of expression. Many of his notions were
inspired by
Karl Abraham's original work, centered around the idea that libido invests certain bodily zones with energy as the child grows older. The order of stages is oral (birth to 8
anal (8 months to 2 years), phallic (two years to 6 years), latency (six to 12 years), genital (puberty to adult). As one masters the stages, one's ability to exert ego control over
one's drives grows. Family conflict can fixate a person on any of these stages and thereby produce a lasting effect on character: the greedy, ever-empty, grasping oral type; the fanatically
orderly and controlling anal type; the thrusting, ambitious phallic type; the quiescent latent type (this one isn't seen as so pathological) -- and the mature outcome of a successful upbringing
or analysis, the genital type, devoted to love and work, but not necessarily in that order. **NOTE -- the ages of these stages stated here differ from the ones presented in texts.**

: whereas a neurosis is a conflict between the ego and id, psychosis is a conflict between ego and reality. Rogers: the end result of a threatening situation. Psychosis occurs when a
person's defenses are overwhelmed, and their sense of self becomes shattered into little disconnected pieces. His behavior likewise has little consistency to it. We see him as having
pscyhotic breaks -- episodes of bizarre behavior. His words may make little sense. His emotions may be inappropriate. He may lose the ability to differentiate self and non-self, and to become
disoriented and passive (see:
threatening situation).
