Carers experience distress due to difficult behaviors and social withdrawal, emphasizing the importance of providing support to prevent further mental illnesses.
A Yale study shows that combining newer antipsychotic drugs with a nicotine patch leads to nearly triple the success rate in quitting smoking for schizophrenic patients. The study found that this combination was particularly effective in reducing carbon monoxide levels, a by-product of cigarette smoke.
A new brain imaging study found that people with schizophrenia exhibit distinct brain changes at the earliest stages of the illness, potentially identifying warning signs and preventing development. The research suggests a role for brain imaging in pinpointing early signs and may lead to preventive psychiatry.
A new study published at the CINP meeting found that treating patients with schizophrenia with Risperdal resulted in a daily savings of $2.80 US per patient, corresponding to an annual saving of $1,022 US. This cost-effectiveness analysis may translate into significant figures given the high prevalence of schizophrenia worldwide.
A new 25-minute test distinguishes between different types of schizophrenia by measuring people's response to a sudden loud noise. Early onset schizophrenia has more severe information processing deficits and is less responsive to current treatments.
Researchers are conducting a nationwide study to identify genes that predispose individuals to major mental illnesses such as depression, bipolar disorder and schizophrenia. The study aims to develop better treatments and tailored medications for these disorders, which often run in families.
A new study finds that Risperdal treatment reduces clinical outcomes, relapse risk by 30%, and significantly lowers medication costs compared to olanzapine. The results suggest that better schizophrenia treatment can improve patients' lives while reducing healthcare burdens.
Researchers have localized a major susceptibility gene for schizophrenia on chromosome 1, according to a study published in Science. The study involved assessing 300 individuals from 22 Canadian families with a high incidence of schizophrenia over a 12-year period.
