Schizophrenia
Schizophrenia is a mental disorder characterized by a breakdown of thought processes and by poor emotional responsiveness. It most commonly manifests itself as auditory hallucinations, paranoid or bizarre delusions, or disorganized speech and thinking, and it is accompanied by significant social or occupational dysfunction. Diagnosis is based on observed behavior and the patient's reported experiences.
Schizophrenia Stories
- A research team identified and prioritized a comprehensive group of genes most associated with schizophrenia that together can generate a score indicating whether an individual is at higher or lower risk of developing the disease.
- Careful analyses of the electrical signals of brain activity, measured using electroencephalography (EEG), may reveal important harmonic relationships in the electrical activity of brain circuits.
A person’s willingness to work may be determined by the levels of dopamine in three different parts of their brain, new research suggests.- Pharmaceutical giant Johnson & Johnson must pay $1.1 billion penalty over shady marketing of its antipsychotic drug Risperdal.
- Scientists have identified some molecules that are responsible for brain cells that reproduce more rapidly in schizophrenic patients by examining cultured neural stem cells derived from the nose of healthy and schizophrenic individuals, according to a new study.
Teens diagnosed with schizophrenia and other psychoses appear to show greater decreases in the brain's gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis.
Researchers have discovered a brain cell malfunction in schizophrenia as DNA stays too tightly wound in certain brain cells of schizophrenic subjects.
The 21-year- old man who calls himself the modern day "Jesus" that's accused of opening fire on the White House, is believed to have a possible case of paranoid schizophrenia, but has yet to be treated.- A new study from researchers at Hudson Alpha Institute for biotechnology, indicate non-familial genetic mutations may account for about half of schizophrenia cases.
- An article in the current issue of Technology & Innovation, Proceedings of the National Academy of Inventors â„¢ reports on the bright future and enormous need for stem cell therapeutics that may offer hope for those suffering from debilitating and deadly diseases. Stem cell transplantation may offer therapy through "simple cell replacement" procedures to restructure damaged organs, tissues and cells, or provide methods for "reawakening" biological cues to regenerate cells.
- There is a significant need for objective tests that could improve clinical prediction of future psychosis.
Two new research studies published in Biological Psychiatry point to progressive abnormalities in brain development that emerge as vulnerable individuals develop schizophrenia.
