Dissociative Identity Disorder: Latest Medical Breakthroughs

Monday, 04 Oct 2010 09:19 AM

Dissociative Identity Disorder (DID) was once called multiple personality disorder. This disorder is characterized by the affected person displaying at least two distinct personality types with unique perception and interaction patterns. These personalities are exhibited in response to triggers like certain events, trauma, certain actions, and can even result from the impact of seeing certain pictures. In some cases, dissociative identity disorder cases can be triggered by anxiety.
Dissociative identity disorder symptoms include memory loss, depression, derealization, phobias, extreme reactions, aggression, and certain comorbidities.
The latest dissociative identity disorder breakthroughs are:
1.Electroencephalography (EEG) test may help predict if a patient will respond to certain drugs prescribed for this psychiatric condition. This study was published by the Clinical Neurophysiology Engineering and Health Sciences researchers at McMaster University. The researchers studied EEG patterns and were able to predict how patients responded to certain drugs. The initial study was conducted for the drug clozapine.
Through this breakthrough, researchers have opened up a new path for the application of machine learning methods for analyzing EEG signals to predict the patient’s response to psychiatric treatment drugs. It is believed that a statistical analysis can be done by incorporating other clinical, laboratory, and personal data that can lead to efficient diagnosis and prescription for psychiatric conditions including dissociative identity disorder.
2.  A study published by Cell Press on August 5, 2010 in the American Journal of Human Genetics finds that a deletion on chromosome 3 relates to the incidence of schizophrenia. This study could lead to finding missing heritability of complex disorders by studying copy number variants or CNVs. The study has found the genes responsible for a whole host of mental disorders.
3. A review of key findings from a conference on Early Life Programming and Neurodevelopmental Disorders held at the University of Pennsylvania in 2009, published in Biological Psychiatry, focuses on early life conditions as a source of adult psychopathology. Data indicates that maternal infection, stress, or exposure to famine can increase the risk for depression in offspring. Studies reveal that adults who have experienced maltreatment during childhood have a higher risk of developing mood disorders and other mental disorders including dissociative identity disorder cases.
4. As published on www.treatdepression.info, vagus nerve stimulation treatment for chronic or recurrent depression is likely to be approved by the FDA. The nerve stimulation treatment is considered effective for dealing with mental disorder cases where antidepressants are found ineffective. This treatment can also be very useful for dissociative identity disorder cases.
