A series of ketamine infusions reduced PTSD symptoms by up to 30% from baseline compared to treatment with midazolam, which reduced symptoms by 20% over the same period. Ketamine treatment significantly reduced three of four PTSD associated symptoms, including intrusive thoughts, avoidance, and negative alterations in cognition and mood.
Researchers have identified a biomarker that can help predict a patient's prognosis and response to therapies for glioblastoma brain cancer subtypes.
According to a new study, cocaine has the most potent effects on the female brain when estrogen levels are at their highest.
A new study reports herpes virus utilizes ancient RNA to proliferate, mimicking the same process tumors have been found to manipulate. The findings could have implications for new treatment options and also may shed light on neurodegenerative diseases.
Long term outcome data of patients with treatment-resistant depression found subcallosal cingulate deep brain stimulation (SCC DBS) was both effective at relieving symptoms and safe.
People with schizophrenia who experience auditory hallucinations have greater activation in specific areas of the auditory cortex in response to sound frequencies. The mapping of sound frequency in the auditory cortex is scrambled in those with schizophrenia, suggesting a disruption in the normal processes for organized sound representation in the brain. As the tonotopic map is established during infancy and remains stable throughout life, the findings suggest vulnerability for auditory hallucinations is linked to defects in the organization of the auditory system during infantile development. This precedes speech development and the onset of psychiatric symptoms.
A new study reports prenatal exposure to common antidepressants and antipsychotics does not increase the risk of a child developing autism.
Altered expression of FYN, a gene associated with the production of Tau, was identified in the brains of people addicted to heroin. Findings suggest opioid use can affect the brain in a way that might cause vulnerability in neural systems that can trigger neurodegeneration later in life.
Mothers who use cannabis during pregnancy to relieve stress may be putting their children at risk of developing anxiety and stress later in life. Researchers found placental tissue revealed cannabis use in mothers was associated with lower expression of immune-activating genes. Cannabis suppression of placental immune-gene networks predicted higher anxiety in children.
Researchers have identified 64 genomic regions that contain genetic variants associated with an increased risk of developing bipolar disorder. The study also revealed a genetic overlap between bipolar disorder and other psychiatric disorders.
Researchers say Black patients are at greater risk of advanced vision loss than white patients following a diagnosis of primary open angle glaucoma.
Researchers have identified key differences between the way males and females with schizophrenia process the emotional states of others than those without the condition. The study reports those with schizophrenia use less complex brain regions than healthy controls to process other people's emotions.
