Aphasiology: Disorders and clinical practice Essay
Acquired Aphasia Introduction Abstract            The paper describes aphasia in details and also the challenges that are faced by the individuals who suffer from aphasia. The paper also describes about the executive functioning and what it entail including the relationship between productivity outcomes and executive functions. The paper also highlights the challenges that aphasia patients face in their day to day lives. For instance, how these individuals handle their daily tasks. The paper shows that these patients face a lot of challenges including discrimination since they are misunderstood by many people. Also this paper shows how these patients can undergo therapy treatment as a way of improving their language and also to be educated on how to cope and interact with other people who do not have aphasia. Finally the paper describes the implications of this therapy treatment on aphasia patients.            Aphasia refers to comprehension impairment and language production which is usually led by damage in language constituent brain hemisphere. Aphasia is a family of disorders involving varying impairment degrees in four fundamental areas: Spoken language comprehension Spoken language expression Reading comprehension, and Written expression            An individual who have aphasia usually have comparatively nonlinguistic cognitive skills which is intact like executive and memory function skills even though these and other cognitive discrepancies may co-occur together with aphasia. Sensory deficits like visual and auditory agnosia and visual field deficits may also be present (Bhagal et al, 2003).            The result of aphasia is challenging to predict due to the wide symptoms variability. Aphasia result varies extensively from individual to individual depending on the brain insult severity and the lesion location. The indicator of the long- term recovery which is easily predictable is initial aphasia severity together with lesion size and site. Other factors which are usually considered concerning prognosis consist of the individual’s education level, gender, age among other comorbidities (Retrieved from http://www.aphasia.com/about-aphasia/who-gets-aphasia). When scrutinized properly, however, these factors appear to be weak predictors of the degree of recovery. Assessment of aphasia is goal-oriented, organized appraisal of the variety of pragmatic, linguistic and cognitive components of language. Executive function refers to the abilities and skills which enables individuals to achieve activities which are goal-directed. Prior to a head injury or traumatic brain, these abilities can be adversely affected (Simmons et al, 2010). Executive Functioning and completing a task Completing a task involves some steps as follows: Planning: planning and/ or knowing the steps for a specific activity Initiation: initiating an activity Doing the task: Executing the plans and at the same time self regulating and self monitoring. Evaluating- checking the outcomes of your work. Changing and improving- checking ways of simplifying the task next time and keeping away from any errors.            The above executive functions are used for all types of everyday tasks like shopping, laundry and cooking. In order to complete a task an individual must initiate each step, put in order, follow through and as this continues adjusting and monitoring of actions should be done. Most individuals do these activities without planning or any thought. However, for a person who is suffering from a brain injury he or she may face a challenge while initiating the task in the initial place. Such individuals may not have a thought of going food shopping and doing the washing even if their fridge is empty or there is a pile of laundry which is dirty, these clear cues may not initiate the thought process which makes them start a plan of action (Dickey et al, 2010).            People with acquired aphasia may start an activity however not have thought it through therefore they make errors. A simple illustration would be going for shopping however forgets carrying a shopping list or wallet. Although this can also happen to any individual however it occurs more frequently if an individual have a brain injury. Individuals with acquired aphasia may not learn from past errors and they end up repeating similar mistakes over and over again while they try accomplishing a task (Mesulam, 2001).            An individual with aphasia usually lack insight into their own capabilities to execute tasks, even in a case where individuals make suggestions which are positive. Treatment and rehabilitation usually involves executing systems and strategies to assist individuals with executive functioning difficulties: Daily organizers and planners Home information centre which includes calendars, notice boards etc. Reserve time each day purposed for planning Use a Dictaphone and timers for reminders Using step by step checklists Executive functions and regulating thinking and behavior            Another purpose of executive functions is that they assist individuals to control their behavior to respond and act properly. Problems with self regulation can result to verbalizations and impulsive behavior and may happen in numerous ways: Uttering inappropriate statements or remarks Dominating the conversation Being rude Being unable to stay on topic Continuously talking about a particular subject            With an aid of a duly qualified language and speech therapist some people with aphasia can be trained on picking up on a listener’s facial expressions or reactions thus realizing when they are making error in their communication. Recovery from aphasia may imply re-learning what facial expressions and social conventions signify, however it may imply just re-learning how to react appropriately to particular facial expression for instance, if a certain person say something and his or her communication partner seems to be shocked this may imply that the person have spoken a wrong thing (Hurkmans et al, 2012). Functional communication and executive function in aphasia            Functional communication refers to the capability of receiving and conveying a message, in spite of the mode, to converse successfully and independently in a particular environment. Broca and wernicke perceived language to be different from cognition where they argued that patients who have aphasia are cognitively integral however they deficits in their language. On the other hand, recent studies shows that cognitive impairments like attention, working memory and sequencing are possessed by individuals who have aphasia. Outcomes illustrates that diminished executive function capability may be linked to declined functional communication capability in individuals with aphasia. The executive function usually depends in communication success (Cherney et al, 2011).            According to Davis et al (2004) functional communication and executive function ability are associated closely in individuals with aphasia. Language impairment may not correlate always with real like communication capability. Thus, executive function may be an ideal functional communication ability indicator (Davis, 2004).            In a case where there is impairment of Executive function in aphasia patients, this may be due to the fact that functional communication capability is more impaired than what is indicated by severity of language impairments.            Relationship between executive functions and productivity outcomes following stroke, disability and rehabilitation            This study shows the need of assessing executive functions thoroughly in order to direct cognitive rehabilitation interventions as a result of a stroke. This is different from carrying out a cognitive screening incorporating merely one or two elements of executive functions.            Additionally, the findings show that more comprehensive evaluation of executive functions may be acceptable for younger people that have suffered from stroke. The evaluation will establish their ability to return to productive tasks which include tailor rehabilitation and employment to provide aid to needs consequently.            Future research is suggested in order to study efficacy of approaches which evaluate the interactive and separate influence of fundamental executive functions and cognitive processes. In addition, methodical assessment of rehabilitation practices to help management of individuals of executive dysfunction in everyday’s life is recommended.            Relations between semantic processing, short-term memory deficits and executive function            Allen et al (2012) shows that semantic processing capabilities, semantic short-term memory deficits are highly related to general or specific executive function deficits. A research was conducted involving a total of 20 patients with STM deficits and aphasia were evaluated on basis of semantic processing, short -term retention and both simple and rigid executive function activities. The study found no evidence that semantic STM deficits result due to deficits in executive function (Brady et al, 2012).            Executive function tasks performance was found to relate with some semantic processing tasks performance proposed that a relational combination function may bring about performance on both sorts of tasks. Correlation between some executive function activities and phonological STM was realized where phonological rehearsal and storage play great role in executive function activities with verbal element (Engelter et al, 2006).            Clinical repercussions for the elucidation of the executive function role in language-processing activities and the achievable contributions of executive function deficits and STM in treatment regimes.            Executive function capabilities depend on fundamental cognitive resources. Relational integration- role in discourse            EF role in treatment of language deficits depends on aspect of language which is being treated.            Found no relation between performance and semantic STM on complex and simple executive function activities (Pedersenet al, 1995). Instead they realized that executive function tasks and phonological STM were related in activities that had a verbal element recommends that performance in several executive function activities depends on rehearsing or maintaining phonological codes. Although semantic STM was unrelated to executive function capability, semantic processing tasks performance was connected to the executive function (Moxley, 2002).            After the completion assessment stage, a plan for treatment is obtained from the outcomes of the assessments. Clinician must assess the form of treatment approach they will utilize. It has been investigated that early intervention is more ideal compared to late intervention. The basic goal in aphasia treatment is to improve functional communication so as to participate in tasks of daily living. The main goal of the patient is to recuperate enough language to carry on with their life normally as possible (Faroqui-Shah et al, 2010). Treatment of executive function and language            Impairment based Approach:            This approach uses cognitive processing to find out the processes and components which have been fractioned as a result of brain damage. The approach also uses normal cognitive processing models to come up with the processes and components, which are damaged. Treatment is determined on basis of these outcomes. The approach argues that brain has ability of reorganizing and that reorganization is shaped directly by the environment. There is a perception that language and executive function will return as a successful treatment product (Teasell et al, 2011). Consequence Approach            It is also known as social, functional, psychological, life participation approach. This approach targets the outcomes of life participation impairment and creates treatment goals on basis of these impairments. A therapist who uses consequence approach should comprehend fully the limitations aphasia has on the life of an individual. The consequences approach influences values and principles which are separate it from impairment based approach (Hier et al, 1994).            There is growing support for the notion that executive/attention function skills in people with aphasia are remediable. Moreover, there is a significant relationship between functional communication and executive/attention function in individuals with aphasia. The outcomes recommend that treatment of executive/attention function in aphasia may lead to measurable variations in these skills and in the conversation communication success. References Bhogal, S.
