Chronic traumatic encephalopathy and the locus coeruleusHealy, Ryan 12 June 2019 (has links)
Chronic Traumatic Encephalopathy (CTE) is a neurodegenerative disease that is associated with repetitive traumatic brain injury like those sustained in sport, military combat, and other activities with repetitive head impact exposure. Repetitive head impacts typically cause mild traumatic brain injury (mTBI) resulting in both concussive and subconcussive injury. Repeated mTBIs injuries appear to cause an abnormal accumulation of proteins, including hyperphosphorylated tau (p-tau) and TDP-43, progressive axonal failure with gradual structural degradation, microvascular disruption, breach of blood-brain barrier, neuroinflammation and microglial activation; each of these manifestations lead to axonal degeneration and neuronal death, which impairs neuronal pathways and are likely to give rise to CTE symptoms. CTE can be microscopically characterized mainly by p-tau accumulation in perivascular spaces and at the depths of the cortical sulci. Clinical presentation of CTE may include behavioral, mood, cognitive, or motor symptoms. Some of the common symptoms include impulsivity, aggression, anxiety, depression, memory impairment, dementia, and suicidality. The Locus Coeruleus (LC), a nucleus in the pons of the brainstem, is suspected to be involved in CTE. The LC provides the main source of norepinephrine to the entire brain and is critical for its control over arousal, behaviors, attention, and memory. Dysfunction of the locus coeruleus has shown to cause a wide array of symptoms, many of which are similar to those seen in CTE. Furthermore, the LC is affected in many other neurodegenerative diseases and is believed to be responsible for the progressive and widespread nature of the various diseases and their clinical symptoms. Although the LC has been implicated in CTE there have been no studies examining LC pathology in relation to the disease progression or its symptoms. We hypothesize LC CTE pathology should increase with the severity of CTE. Furthermore, increased CTE pathology in the LC should create disturbances to the LC and the LC-NE system and manifest clinically. Specifically, LC CTE pathology may be associated with age of onset of general behavioral and cognitive symptoms as well as individual symptoms and outcomes including impulsivity, depression, depressed mood and death by suicide. To determine this, a postmortem study was performed on 184 individuals with a history of RHI and no comorbid diseases examining the relationship between AT8-immunopositive tau density in the LC and various clinical variables. The study found that LC AT8 density showed a significant positive correlation with duration of repetitive head impact (RHI) exposure when controlled for age. There also was a significant increase in LC AT8-immunoreactive tau in cases with stage III and IV CTE compared to those with no CTE and stage I and II CTE, and AT8 density was predictive of CTE stage when controlled for age. There were no significant relationships found between density of LC AT8-immunoreactive tau and age of any CTE symptom onset or individual symptom (impulsivity, depressed mood, MDD, death by suicide) presence. Future studies should continue to evaluate CTE pathology in the LC and its effects on both the pathological and clinical characteristics of the disease.

Coping and psychological distress among head and neck cancer patientsElani, Hawazin. January 2008 (has links)
Objectives: To identify correlates of psychological distress and to investigate how coping skills, anxiety and depression are related in a group of head and neck cancer patients 6-12 months after their diagnosis. Methods: We evaluated in 107 head and neck cancer patients their anxiety and depression levels using the Hospital Anxiety and Depression Scale, and their Coping strategies using the Ways of Coping Checklist. Results: There were statistically significant associations between gender and anxiety level, and between living arrangements, cancer site, time since treatment, tumor stage and depressive symptoms. Results also showed that patients used a variety of coping strategies. Different coping strategies were used in subjects with high versus those with low levels of anxiety or depressive symptoms. Conclusion: Data show several correlates of psychological distress in head and neck cancer patients. They also suggest that coping strategies of these patients vary according to their level of psychological distress.

The prediction of functional outcome by trauma scores in infants and young children with traumatic head injuriesTrance, Deborah A. January 1991 (has links)
Thesis (M.S.)--Boston University / PLEASE NOTE: Boston University Libraries did not receive an Authorization To Manage form for this thesis or dissertation. It is therefore not openly accessible, though it may be available by request. If you are the author or principal advisor of this work and would like to request open access for it, please contact us at open-help@bu.edu. Thank you. / In this pilot study, 28 subjects ages 0 to 6 years who had sustained head injuries were assessed as to their functional status at one and six months post hospital discharge. The functional assessments used were the Rand Child Health Scale, the Battelle Developmental Inventory Screening Test, the Battelle Developmental Inventory Motor Domain, and the Pediatric Evaluation of Disability Inventory. Correlations between these functional measures and trauma scores reported through the National Pediatric Trauma Registry (Glasgow Coma Scale; Injury Severity Score, and Pediatric Trauma Score) were calculated to determine the predictive capacity of the trauma scores in determining functional outcome. The trauma scores were not found to be reliable predictors of functional outcome in these young children. / 2031-01-01
