5 Factors Help Predict Psychosis in Children
Family history of schizophrenia, social withdrawal among symptoms, study
finds
(January 9, 2008) -- (HealthDay News) -- It may be possible to predict who
will develop psychotic illnesses, such as schizophrenia and bipolar
disorder, very early in the disease process, a new study says.
The study found five factors that were often present prior to the
diagnosis of a psychotic disorder in children who were already at high risk
of such disorders. When three or more of these factors were present, the
study found an 80 percent likelihood of developing psychosis within two and
a half years.
"Not everybody who has early symptoms goes on to develop psychosis. But
if we identify the group in which 80 percent will develop psychosis, the
efforts of intervention would be best applied to those at highest risk,"
said study author Tyrone D. Cannon, the Staglin Family professor of
psychology, psychiatry and biobehavioral sciences at the University of
California, Los Angeles.
Results of the study were published in the Jan. 7 issue of the Archives
of General Psychiatry.
Cannon said it's not yet known if early intervention with anti-psychotic
medications would help prevent the development of psychotic illnesses. He
said two studies have suggested that early psychological intervention might
be more useful, because they can give teens skills for staying connected,
solving problems and for conflict resolution.
Symptoms of psychosis are seen in numerous mental health disorders, such
as bipolar disorder, schizophrenia, depression, and with some forms of
alcohol or drug abuse, according to the American Academy of Child and
Adolescent Psychiatry (AACAP). The two most common psychotic symptoms are
delusions and hallucinations, according to AACAP. Delusions are false but
firmly held beliefs. Hallucinations are false sensory perceptions, such as
hearing voices when no one is talking.
While these symptoms can certainly be disturbing, Cannon said, "most
people with psychotic disorders aren't really more prone to violence." And,
he added, this study wasn't designed to address violence or the potential
for violence in those with psychotic illness, so it isn't clear if earlier
identification and intervention for these illnesses could help prevent
incidents like school shootings.
Cannon and his colleagues prospectively studied 291 young people who
sought mental health treatment at one of eight different treatment centers
in North America. The average age of the study participants was 18 years,
and all sought treatment for early symptoms of psychosis, such as unusual
thoughts.
During the two-and-a-half-year follow-up, 35 percent of this group went
on to develop psychotic illness.
The researchers identified five factors that could help predict the
eventual development of psychosis. These included a family history of
schizophrenia with recent deterioration in functioning; higher levels of
unusual thoughts; higher levels of suspicion or paranoia; greater social
impairment; and a history of substance abuse.
When two or three of these factors were present, the odds of psychotic
illness jumped. Two factors increased the likelihood of psychotic illness to
68 percent, and three factors combined raised the risk to 80 percent.
"This was a really good study in terms of size, and once it's replicated
can add on to the field," said Dr. Christopher Lucas, an associate professor
of child and adolescent psychiatry at the New York University School of
Medicine and the director of the Early Childhood Service at the New York
University Child Study Center.
But, the question is, Lucas added, "If you have somebody with this
picture, do you treat them prophylactically?"
Both Lucas and Cannon noted that this study was done on a high-risk
population, so it can't be generalized for the whole population.
Parents need to be on the lookout for a child who withdraws
socially and stops participating in activities he or she once enjoyed,
according to Cannon. He said it's not usually until a child is receiving
mental health treatment that they admit to having delusions or hearing
voices or feeling a greater sense of suspicion, so parents might not notice
such symptoms. Parents should be especially wary of any of these symptoms if
there's a family history of psychotic illnesses, according to the study.
