Analysis
of the cerebrospinal fluid may be used to detect cases of schizophrenia
(02/06/06)
A study published recently shows that soon we may be able to
detect brain disease before symptoms even begin, by examining the
contents of the cerebrospinal fluid, the clear liquid present our
brain and spinal cord. Changes in the levels of certain lipids,
like cholesterol, and proteins in the cerebrospinal fluid may be
linked to various brain conditions, including schizophrenia and
depression.

Brain
imaging studies of the brain may reveal early signs of schizophrenia
(03/19/05)
There is a decline in function in an area of the brain called
the prefrontal cortex in high-risk individuals experiencing early
symptoms of schizophrenia that may reflect biological changes that
precede the onset of the illness. Brain imaging examinations may
reveal these changes, a new study shows.

Researchers
say schizophrenia can be predicted long before symptoms develop
(01/07/05)
Researchers
at Edinburgh University in Scotland say schizophrenia can be predicted
in high risk groups years before symptoms and psychosis are developed.
The signs include social withdrawal, odd behaviour, and feelings
of being disconnected from reality.

New imaging
test may be used to diagnose schizophrenia (05/01/04)
An
American research team have developed a new method for diagnosing
schizophrenia, which includes the identification of an abnormal
pattern in an area of the brain that governs hearing. Abnormalities
in the structure and function of the brain cortex are characteristic
features of the brains in persons with schizophrenia, particularly
in an area called the superior temporal gyrus (SRG). A reduction
in size of the SRG may correlate with auditory hallucinations and
of thought disturbances.

New device
may help solve mysteries around mental illness (11/17/03)
Researchers at University of Colorado in the US have developed
a new device they call the Whole-Head MEG system. The system can
be used to study and photograph a person's brain at work. The researchers
hope the device will help answer many question about brain diseases
like schizophrenia and bipolar disorder.

Modern techniques
facilitate diagnosis of psychiatric disorders (08/15/03)
Psychiatric
disorders are among the hardest to diagnose. Until fairly recently,
diagnoses were still based entirely on the patient's own report
of symptoms and the psychiatrist's observations of the patient's
behavior. However, with the modern techniques that are being developed
today, such as genetic testing and neuroimaging techniques, it is
starting to get easier to diagnose and diistinguish psychiatric
conditions like schizophrenia, autism, bipolar disorder and major
depression.

Protein levels
may be used to differentiate schizophrenia and bipolar disorder
(03/01/03)
It has been previously demonstrated that the elevels of a protein,
apolipoprotein D (apoD), are elevated in certain brain regions in
subjects with schizophrenia and bipolar disorder compared to controls.
A current study has found evidence that the distriubution of ApoE
elevation is different in schizophrenic and bipolar disorder patients.
These differences may be used in the diagnosis to separate these
disorders.

Changes
in the brain may be used to predict psychosis (02/03/03)
A current study in medical journal The Lancet shows that some
of the abnormalities in the gray matter of the brain that are associated
with psychotic disorders may be observed before symptoms occur,
whereas other anatomical changes are developed only once the symptoms
start to show. These findings could be useful both for understanding
the clinical course of the disease in psychotic disordes and for
developing new methods for diagnosis.

Heart rhythm measurements
in the diagnosis of psychiatric illness (08/02/02)
Research has demonstrated abnormal heart rate patterns that
are associated with depression, anxiety, panic disorder, and schizophrenia.
The assessment of these patterns is a new methodology for documenting
physiological dysregulation associated with psychiatric illness.
This type of analysis may be a promising new method for analysis
in psychiatric research and health care.

MRI in the
diagnosis of mental illness (01/31/02)
Magnetic resonance imaging - MRI - is an advanced imaging method
to detect changes in for instance the brain's anatomy, metabolism,
and blood flow. At Harvard University
researchers are now working on a computerized method for interpreting
brain MRI scans. The researchers hope the technique will make it
simpler and cheaper for physicians to make an early diagnosis of
neurodegenerative conditions like Alzheimer's disease and schizophrenia.
To diagnose mental illness may thus soon be as simple as checking
a patient't blood pressure.

Childhood-onset
schizophrenia may be confused with mood disorders (12/10/01)
There
is an evident risk for confusing symptoms of psychic mood disorders
with childhood-onset schizophrenia, according to child psychiatry
experts at National Institute of Mental Health (NIMH), Bethesda,
USA.
As part of an investigation of childhood-onset
schizophrenia (COS) children diagnosed with COS were referred to
the research team in Bethesda. The experts however found that several
of these children had received an incorrect diagnosis. To investigate
this situation, the researchers studied 33 patients who had been
re-diagnosed as suffering from of a mood disorder rather than schizophrenia.
Diagnostic reliability study were performed, including reevaluation
by three psychiatrists who were blind to the initial research diagnosis.
Also, pilot follow-up data regarding current function and treatment
status were obtained for a majority of the subjects.
Interrater reliability, reliability between
raters and NIMH research diagnoses and agreement for patients with
mood disorders were all excellent or good. Pilot follow-up data
indicate that none of the subjects with a diagnosed mood disorder
developed a clinical course resembling schizophrenia.
The authors conclude that: "Many of
the patients referred to the NIMH COS study with clinical diagnoses
of schizophrenia had psychotic mood disorders ..., and these research
diagnoses were reliable. The diagnosis of COS is difficult and requires
a time-consuming evaluation process.

Telling patients
with schizophrenia their diagnosis
(04/09/01)
Psychiatrist
Robert A. Clafferty and coworkers have studied if psychiatrists
themselves may contribute to the misunderstandings surrounding schizophrenia
by avoiding discussion of the diagnosis with their patients. All
consultant psychiatrists working in Scotland was contacted by using
a postal questionnaire. Close to 250 responded. Almost everyone
(95%) thought the consultant psychiatrist was the most appropriate
person to tell a patient their diagnosis of schizophrenia. However,
far from all psychiatrists reported doing so. In fact, 15% would
not use the term "schizophrenia". The researchers found
that a and a variety of confusing terminology was used.
The authors conclude that "greater openness
by psychiatrists about the diagnosis of schizophrenia may be an
essential first step in reducing stigma."

Schizophrenia
linked to father's age (04/12/01)
According
to a recently published study, older fathers are more likely to
have children with predisposal for schizophrenia. The study, which
is published in the April issue of Archives
of General Psychiatry, shows that fathers aged 50 or older are
almost three times more likely to have a child with schizophrenia.
This supports previous studies demonstrating a link between older
fathers and other gene-related diseases.

Possible test for schizophrenia (01/29/01)
In the current issue of BMJ (vol 322, p192), Judy Siegel-Itzkovich
reports from Jerusalem:
"Israeli researchers may have found a way to diagnose schizophrenia
by analysing white blood cells for signs of a chemical that is overactive
in patients with the psychiatric condition. Psychiatrists may be
able to give patients a simple blood test to determine at an early
stage whether a patient has the disorder instead of observing behaviour
for at least six months before diagnosing and treating it. The blood
test, which has been patented but is not likely to be commercially
available for several years, was proposed and tried on patients
by Professor Sara Fuchs of the immunology department of the Weizmann
Institute of Science in Rehovot and by graduate student Tal Ilani."
