Evaluation of brain injury related behavioral disturbances in community mental health centers

The high burden of traumatic brain injury and comorbidities amongst homeless adults with mental illness

OBJECTIVE

characterize the prevalence of self-reported head injury with loss of consciousness (LOC) and associated demographic, clinical and service use factors in a sample of homeless adults with mental illness.

METHOD

Participants in the At Home/Chez Soi study were interviewed at the time of study enrollment regarding their history of head injuries, mental and physical health diagnoses and justice system and healthcare interactions. Sociodemographic and clinical data were also collected.

RESULTS

Over half of the 2088 study respondents (52.6%, n = 1098) reported a history of head injury with a LOC, which was associated with several demographic, clinical and service use variables in this population. With respect to specific mental health conditions, a history of head injury with LOC was associated with higher odds of current depression (OR = 2.18, CI: 1.83-2.60), manic episode or hypomanic episode (OR = 1.91, CI: 1.45-2.50), PTSD (OR = 2.98, CI: 2.44-3.65), panic disorder (OR = 2.37, CI:1.91-2.93), mood disorder (OR = 1.78, CI: 1.40-2.26) and alcohol (OR = 2.09, CI: 1.75-2.49) and drug (OR = 1.73, CI: 1.46-2.06) misuse disorders, but reduced odds of having diagnosis of a psychotic disorder (OR = 0.63, CI: 0.53-0.76). A history of head injury with LOC was also associated with increased use of variety of services, including family medicine (OR = 1.33, CI: 1.12-1.59), criminal justice system (OR = 1.50, CI: 1.25-1.80) and the emergency department (OR = 1.03, CI: 1.01-1.05).

CONCLUSIONS

Amongst homeless adults with mental illness having a history of head injuries with LOC was independently associated with various adverse outcomes. These individuals constitute a high-risk group who may benefit from specialized services.

The mental health sequelae of traumatic head injury in South Vietnamese ex-political detainees who survived torture

Little is known about the relationship between traumatic head injury (THI) and psychiatric morbidity in torture survivors. We examine the relationship between THI and depression, PTSD, post-concussive syndrome (PCS), disability and poor health status in Vietnamese ex-political detainees who survived incarceration in Vietnamese re-education camps. A community sample of ex-political detainees (n=337) and a non-THI, non-ex-detainee comparison group (n=82) were surveyed. Seventy-eight percent of the ex-political detainees had experienced THI; 90.6% of the ex-political detainees and 3.6% of the comparison group had experienced 7 or more trauma events. Depression and PTSD were greater in ex-detainees than in the comparison group (40.9% vs 23.2% and 13.4% vs 0%). Dose-effect relationships for THI and trauma/torture in the ex-political detainee group were significant. Logistic regression in the pooled sample of ex-detainees and the comparison group confirmed the independent impact of THI from trauma/torture on psychiatric morbidity (OR for PTSD=22.4; 95% CI: 3.0-165.8). These results demonstrate important effects of THI on depression and PTSD in Vietnamese ex-detainees who have survived torture.

Perceptions of Long-term Community-based Support Following Severe Acquired Brain Injury

Many individuals require long-term community-based support following acquired brain injury (ABI). However, very few studies have examined individuals' perceptions of these support needs. The present exploratory study examined individuals' perceptions of community-based support following severe ABI. Participants included eight individuals (aged 20–48 years) with severe ABI, seven relatives and three case managers. The individuals were receiving long-term specialised lifestyle support ranging from 3–70 hours per week. A structured interview with open and closed questions was developed to explore perceptions of individuals' support needs across the areas of personal and home-based activities, community-based activities, self-organisation and vocational activities and social and psychological well-being. The questions investigated whether support was needed, the importance of support, the sources of support, the effectiveness of support and the need for change. A comparison of the three respondent groups' perceptions of support indicated a general consensus that community-based activities were the most important and most effective area of support. When the issues raised by the three respondent groups were compared and contrasted two main themes emerged from the data, which were labelled “relationships” and “individual choice versus support needs”. These themes are discussed in relation to the provision of long-term community-based support services following ABI.

The use of newer anticonvulsants in neuropsychiatric disorders

Anticonvulsants are becoming increasingly popular for the management of psychiatric and neuropsychiatric syndromes. This may be related to antikindling properties of these agents in addition to modulation of gamma-aminobutyric acid, serotonin, and other neurotransmitters. Treatment selection is complicated by the inconsistent availability of randomized controlled data among the growing range of choices. Moreover, generalization of psychiatric to neuropsychiatric applications of anticonvulsant treatments is not universally applicable. This paper reviews the use of newer anticonvulsants in the management of neuropsychiatric disorders, particularly aggression and agitation. The largest body of treatment data is available for valproic acid, which appears to be efficacious and well-tolerated in a wide range of neuropsychiatric disorders. Less consistent data are available for other medications. Further prospective studies are warranted to examine the use of these medications in neuropsychiatric populations.

Depression after traumatic brain injury: conceptualization and treatment considerations

The understanding and treatment of depression that develops following traumatic brain injury (TBI) is still unclear and likely to be the result of a complex variety of interacting factors. Past researchers have developed ways to classify important variables related to patients' depression into broad domains such as: Pre-injury assets and liabilities, the nature and severity of brain injury; and reaction to difficulties. However, a better conceptualization of the problem is required in order to guide the assessment and treatment considerations for depressed patients with TBI. This review provides this conceptualization by postulating six theoretical relationships between depression and TBI. The degree of empirical support provided in the literature for these links is indicated. Research findings suggested that an individual with TBI is the most susceptible to depression when any of the following conditions exist: a pre-existing psychiatric disturbance is exacerbated; the injury sustained involved the left anterior region of the brain; and when her individual has poor insight into her deficits, attempts to resume her pre-injury roles and experiences significant failure. For each relationship, a likely outcome is predicted if the recommended treatment plan is not conducted. The present conceptualization and treatment considerations will be of substantial benefit to clinicians working in the area.
