Axis I and II psychiatric disorders in patients with traumatic brain injury: a 12-month follow-up study.
ABSTRACT To evaluate the occurrence of axis I and II psychiatric disorders among patients with traumatic brain injury (TBI).
Prospective observational study. Forty-five adult patients, who had attended an emergency unit because of TBI, were recruited. At 12 months, 38 patients were interviewed.
Psychiatric disorders were evaluated using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN) and the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II).
Before TBI, the 12-month rate of axis I psychiatric disorders was relatively high (39.5%) and the rate of alcohol dependence was especially elevated (18.4%). During the 12 months after TBI, axis I disorders were found in 47.4% of subjects. Six patients (15.8%) were found to have a disorder with an onset after TBI. Of these, five patients had depressive disorders (13.2%). Almost one third of the subjects (29.0%) had personality disorders. Antisocial and obsessive-compulsive personality disorders were the most frequent (10.5%).
Both axis I and II psychiatric disorders are common among patients with TBI. Alcohol dependence and personality disorders are prevalent in individuals prone to TBI, whereas depressive disorders typically develop after injury. Psychiatric disorders should be addressed in rehabilitation, as otherwise they will hinder the recovery after TBI.

ABSTRACT: Mild traumatic brain injury (mTBI) refers to the clinical condition of transient alteration of consciousness as a result of traumatic injury to the brain. The priority of emergency care is to identify and facilitate the treatment of rare but potentially life-threatening intracranial injuries associated with mTBI through the judicious application of appropriate imaging studies and neurosurgical consultation. Although post-mTBI symptoms quickly and completely resolve in the vast majority of cases, a significant number of patients will complain of lasting problems that may cause significant disability. Simple and early interventions such as patient education and appropriate referral can reduce the likelihood of chronic symptoms. Although definitive evidence is lacking, mTBI is likely to be related to significant long-term sequelae such as Alzheimer disease and other neurodegenerative processes.Emergency medicine clinics of North America 08/2010; 28(3):571-94. · 0.96 Impact Factor

ABSTRACT: Traumatic brain injury (TBI) is a worldwide public health problem. Over the last several decades, improvements in acute care have resulted in higher survival rates. Unfortunately, the majority of survivors of moderate and severe TBI have chronic neurobehavioral sequelae, including cognitive deficits, changes in personality and increased rates of psychiatric illness. These neurobehavioral problems are understandable in the context of the typical profile of regional brain damage associated with trauma. This paper presents an overview of the neurobehavioral sequelae of TBI and outlines issues to consider in the evaluation and management of these challenges.World psychiatry: official journal of the World Psychiatric Association (WPA) 03/2008; 7(1):3-10. · 8.97 Impact Factor

ABSTRACT: Traumatic brain injury (TBI) is a worldwide public health problem typically caused by contact and inertial forces acting on the brain. Recent attention has also focused on the mechanisms of injury associated with exposure to blast events or explosions. Advances in the understanding of the neuropathophysiology of TBI suggest that these forces initiate an elaborate and complex array of cellular and subcellular events related to alterations in Ca(++) homeostasis and signaling. Furthermore, there is a fairly predictable profile of brain regions that are impacted by neurotrauma and the related events. This profile of brain damage accurately predicts the acute and chronic sequelae that TBI survivors suffer from, although there is enough variation to suggest that individual differences such as genetic polymorphisms and factors governing resiliency play a role in modulating outcome. This paper reviews our current understanding of the neuropathophysiology of TBI and how this relates to the common clinical presentation of neurobehavioral difficulties seen after an injury.Dialogues in clinical neuroscience 01/2011; 13(3):287-300.
