This 'presentation bias' echoes publication bias seen in major journals and may impact clinical care.
Dr. Elizabeth Osuch has received a $100,000 grant to improve diagnosis of bipolar disorder in youth through functional brain imaging. The average misdiagnosis often lasts 6-10 years and can lead to declining patient condition if treated with antidepressants.
Two Johns Hopkins psychiatrists argue that the Diagnostic and Statistical Manual of Mental Disorders (DSM) needs radical change due to its current 'field guide' form, which provides checklists of symptoms but lacks underlying causes. The manual's limitations make it difficult for clinicians to direct treatment or investigate disorders.
Suicide rates among psychiatric in-patients have fallen by 29-31% between 1997 and 2008, according to a new study. Young patients and those with schizophrenia saw the largest declines. However, the risk of suicide for recently discharged patients may have increased over the same period.
