Altered brain structure in pathological narcissism

Published: Wed, 19 Jun 2013 14:14:14 GMT

A far-reaching disorder of the self-esteem is denoted as a narcissistic personality disorder. Persons with pathological narcissism on the one hand suffer from feelings of inferiority, while on the other hand projecting themselves to the world as arrogant, disparaging and self-absorbed. One of the key features of a narcissistic personality disorder is the lack of empathy. Although patients suffering from such a disorder are well able to recognize what other persons feel, think and intent, they display little compassion.

Scan predicts whether therapy or meds will best lift depression

Published: Wed, 12 Jun 2013 20:23:23 GMT

Pre-treatment scans of brain activity predicted whether depressed patients would best achieve remission with an antidepressant medication or psychotherapy, in a study that may help mental health treatment decision-making move beyond trial-and-error. The study sought to identify a biomarker that could predict which type of treatment a patient would benefit from based on the state of his or her brain.

New imaging technique holds promise for speeding MS research

Published: Wed, 12 Jun 2013 20:23:23 GMT

Researchers have developed a new magnetic resonance imaging technique that detects the telltale signs of multiple sclerosis in finer detail than ever before -- providing a more powerful tool for evaluating new treatments.

Frequent soccer ball 'heading' may lead to brain injury

Published: Tue, 11 Jun 2013 12:22:22 GMT
