People who reported hearing voices or having anxiety were the ones more likely to be misdiagnosed, according to theContinue reading “Reported Symptoms of Anxiety, Hearing Voices Most Common Reasons for Misdiagnosis of Schizophrenia”

Small RNA identified that offers clues for quieting the “voices” of schizophrenia

St. Jude Children’s Research Hospital scientists have linked disruption of a brain circuit associated with schizophrenia to an age-related decline in levels of a single microRNA in one brain region St. Jude Children’s Research Hospital scientists have identified a small RNA (microRNA) that may be essential to restoring normal function in a brain circuit associatedContinue reading “Small RNA identified that offers clues for quieting the “voices” of schizophrenia”

New research links subgroups of schizophrenia to specific visualized brain anomalies

An international team of researchers has linked specific symptoms of schizophrenia with various anatomical characteristics in the brain, according to research published in NeuroImage. By analyzing the brain’s anatomy with magnetic resonance imaging (MRI), researchers from the University of Granada, Washington University in St. Louis, and the University of South Florida have demonstrated the existenceContinue reading “New research links subgroups of schizophrenia to specific visualized brain anomalies”

Eye tests may predict schizophrenia

Schizophrenia is associated with structural and functional alterations of the visual system, including specific structural changes in the eye. Tracking such changes may provide new measures of risk for, and progression of the disease, according to a literature review published online in the journal Schizophrenia Research: Cognition, authored by researchers at New York Eye andContinue reading “Eye tests may predict schizophrenia”

Meet the Man Trying to Use Ayahuasca to Treat PTSD

Deep in the Amazon rainforest, a group of veterans chokes down a gritty, gut-wrenching shot of liquid absolution. They try to drink away their severe mental disturbances, but not the way you drink away your ex-girlfriend with a bottle of whiskey. They’re looking for a cure. Their leader: 27-year-old retired infantryman Ryan LeCompte. Their goal:Continue reading “Meet the Man Trying to Use Ayahuasca to Treat PTSD”

In the first caseContinue reading “Man experiencing headaches, seizures, memory flashbacks and strange smells discovered to have had tapeworm living in his brain for 4 years”

7 Very Bizarre (and Very Rare) Psychotic Hallucinations

brain The many documented cases of strange delusions and neurological syndromes can offer a window into how bizarre the brain can be. It may seem that hallucinations are random images that appear to some individuals, or that delusions are thoughts that arise without purpose. However, in some cases, a specific brain pathway may create aContinue reading “7 Very Bizarre (and Very Rare) Psychotic Hallucinations”
