Researchers recently examined the effects of cognitive behavioural therapy (CBT) on brain functioning in depressed patients and found that the psychotherapeutic approach made actual changes in the brain [1]. The study was published in the journal Social Cognitive and Affective Neuroscience.
Hearing voices that are not there was once thought to be a core symptom of schizophrenia and signify severe mental illness. It has been increasingly acknowledged that people with no other symptoms of schizophrenia or psychosis do hear voices [1]. There are several theories about what causes these auditory hallucinations. For example, there is good evidence that hearing voices can be linked to trauma [2]. Attempting to understand the phenomenon is not only scientifically interesting but also relates to how society views people with these experiences and if and how they may be treated. A search for how these experiences are associated with brain function is ongoing. New research published in the journal Human Brain Mapping suggests that the predisposition to hearing voices may relate to abnormal functioning of the brain whilst at rest [3].
Some children who are accurately diagnosed in early childhood with autism lose the symptoms and the diagnosis as they grow older, a study supported by the National Institutes of Health has confirmed [1]. The research team made the finding by carefully documenting a prior diagnosis of autism in a small group of school-age children and young adults with no current symptoms of the disorder.
Scientists at Johns Hopkins University are developing a new early warning system for seizures that is sensitive enough to detect imminent seizures without setting off a large number of false alarms. The software may someday be embedded in a microchip that would continually check electrical activity in the brain and launch electrical stimulation whenever a seizure is beginning to form.
