In a new study from Dr. Andrew Nicholson (left) and Dr. Ruth Lanius (right), brain imaging is shown to be a promising tool for early diagnosis of psychiatric illness.
Psychiatric disorders are often difficult to diagnose. As research advances, we are learning there are multiple subtypes of illness that differ in symptoms and treatment needs, making classification even harder. Post-traumatic stress disorder (PTSD) is one example. Individuals with the more common type of PTSD experience active defensive responses like hyperarousal or outbursts of emotion while those with the dissociative subtype experience additional passive defensive responses like ‘shutting down’ or out-of-body experiences.
