Acquired brain injury

Acquired brain injury (ABI) is brain damage caused by events after birth, rather than as part of a genetic or congenital disorder such as fetal alcohol syndrome, perinatal illness or perinatal hypoxia. ABI can result in cognitive, physical, emotional, or behavioural impairments that lead to permanent or temporary changes in functioning. These impairments result from either traumatic brain injury (e.g. physical trauma due to accidents, assaults, neurosurgery, head injury etc.) or nontraumatic injury derived from either an internal or external source (e.g. stroke, brain tumours, infection, poisoning, hypoxia, ischemia, encephalopathy or substance abuse). ABI does not include damage to the brain resulting from neurodegenerative disorders.Symptoms:Behavioral manifestations: Acquired brain injury (ABI) is brain damage caused by events after birth, rather than as part of a genetic or congenital disorder such as fetal alcohol syndrome, perinatal illness or perinatal hypoxia. ABI can result in cognitive, physical, emotional, or behavioural impairments that lead to permanent or temporary changes in functioning. These impairments result from either traumatic brain injury (e.g. physical trauma due to accidents, assaults, neurosurgery, head injury etc.) or nontraumatic injury derived from either an internal or external source (e.g. stroke, brain tumours, infection, poisoning, hypoxia, ischemia, encephalopathy or substance abuse). ABI does not include damage to the brain resulting from neurodegenerative disorders. While research has demonstrated that thinking and behavior may be altered in virtually all forms of ABI, brain injury is itself a very complex phenomenon having dramatically varied effects. No two persons can expect the same outcome or resulting difficulties. The brain controls every part of human life: physical, intellectual, behavioral, social and emotional. When the brain is damaged, some part of a person's life will be adversely affected. Consequences of ABI often require a major life adjustment around the person's new circumstances, and making that adjustment is a critical factor in recovery and rehabilitation. While the outcome of a given injury depends largely upon the nature and severity of the injury itself, appropriate treatment plays a vital role in determining the level of recovery. ABI has been associated with a number of emotional difficulties such as depression, issues with self-control, managing anger impulses and challenges with problem-solving, these challenges also contribute to psychosocial concerns involving social anxiety, loneliness and lower levels of self esteem. These psychosocial problems have been found to contribute to other dilemmas such as reduced frequency of social contact and leisure activities, unemployment, family problems and marital difficulties. How the patient copes with the injury has been found to influence the level at which they experience the emotional complications correlated with ABI. Three coping strategies for emotions related to ABI have presented themselves in the research, approach-oriented coping, passive coping and avoidant coping. Approach-oriented coping has been found to be the most effective strategy, as it has been negatively correlated with rates of apathy and depression in ABI patients; this coping style is present in individuals who consciously work to minimize the emotional challenges of ABI. Passive coping has been characterized by the person choosing not to express emotions and a lack of motivation which can lead to poor outcomes for the individual. Increased levels of depression have been correlated to avoidance coping methods in patients with ABI; this strategy is represented in people who actively evade coping with emotions. These challenges and coping strategies should be kept in consideration when seeking to understand individuals suffering from ABI. Following acquired brain injury it is common for patients to experience memory loss; memory disorders are one of the most prevalent cognitive deficits experienced in sufferers. However, because some aspects of memory are directly linked to attention, it can be challenging to assess what components of a deficit are caused by memory and which are fundamentally attention problems. There is often partial recovery of memory functioning following the initial recovery phase; however, permanent handicaps are often reported with ABI patients reporting significantly more memory difficulties when compared people without an acquired brain injury. In order to cope more efficiently with memory disorders many people with ABI use memory aids; these included external items such as diaries, notebooks and electronic organizers, internal strategies such as visual associations, and environmental adaptations such as labelling kitchen cupboards. Research has found that ABI patients use an increased number of memory aids after their injury than they did prior to it and these aids vary in their degree of effectiveness. One popular aid is the use of a diary. Studies have found that the use of a diary is more effective if it is paired with self-instructional training, as training leads to more frequent use of the diary over time and thus more successful use as a memory aid. In children and youth with pediatric acquired brain injury the cognitive and emotional difficulties that stem from their injury can negatively impact their level of participation in home, school and other social situations, participation in structured events has been found to be especially hindered under these circumstances. Involvement in social situations is important for the normal development of children as a means of gaining an understanding of how to effectively work together with others. Furthermore, young people with ABI are often reported as having insufficient problem solving skills. This has the potential to hinder their performance in various academic and social settings further. It is important for rehabilitation programs to deal with these challenges specific to children who have not fully developed at the time of their injury. Rehabilitation following an acquired brain injury does not follow a set protocol, due to the variety of mechanisms of injury and structures affected. Rather, rehabilitation is an individualized process that will often involve a multi-disciplinary approach. The rehabilitation team may include but is not limited to nurses, neurologists, physiotherapists, occupational therapists, speech-language pathologists, music therapists, and rehabilitation psychologists. Physical therapy and other professions may be utilized post- brain injury in order to control muscle tone, regain normal movement patterns, and maximize functional independence. Rehabilitation should be patient-centered and guided by the individual’s needs and goals.
