Brain Research: Brain structure reveals ability to regulate emotions ♦ Source of debilitating memory loss ♦ New insights into the circuitry of PTSD

Source of debilitating memory loss in people with psychosis discovered As disabling as its delusions and hallucinations, psychosis' devastating toll on memory arises from dysfunction of frontal and temporal lobe regions in the brain that rob sufferers of the ability to make associative connections, a study has found, pinpointing potential target areas for treatments to help the more than 3.2 million Americans for whom medication quells the voices and visions, but not the struggle to remember.

Scientists identify schizophrenia's 'Rosetta Stone' gene  A breakthrough reveals gene's influence in a vulnerable period of the brain's development. Researchers hope it could offer a therapeutic target for reversing the disease. There is 'strong evidence' that subtle changes early on in life can lead to 'much bigger' effects in adulthood.

New insights into the circuitry of PTSD, mild traumatic brain injury Posttraumatic stress disorder (PTSD) and traumatic brain injury (TBI) can have devastating consequences. Both are associated with high rates of disability and suicide, and although they are separate conditions, they commonly co-occur. For example, a soldier who has developed PTSD as a result of a traumatic experience may have also sustained a brain injury during that experience.

Brain structure reveals ability to regulate emotions People diagnosed with a personality disorder may find it difficult to function in society due to difficulties in regulating emotions -- but also healthy individuals differ in how often they become irritated, angry or sad. Scientists have published a study where they show that the affected brain areas in people with a clinical diagnosis are also affected in healthy individuals.
