Often medications to treat anxiety quality lincocin 500 mg, patients will describe being easily overstimulated and overwhelmed when there are too many noise or visual distractions in the immediate environment. Having the patient articulate the words aloud while they read may also assist with selfcueing and focusing attention on a reading task. Attention test on which selective attention accuracy (errors of omission and commission) and amount of information processed (accurate target detection speed) are measured. As with most neuropsychological tests, there are few that purely measure a single construct. For example, the DelisKaplan Executive Function System Color­Word Interference Test measures information pro cessing speed and response inhibition as well as shift set maintenance. There is considerable overlap between atten tion abilities and information processing speed. Individuals without brain injury are usually capable of completing tasks both accurately and within a reasonable period of time. The Wechsler Adult Intelligence Scale­Fourth Edition contains four indices that are ana lytically derived from the subtests of the test. The Verbal Comprehension, Perceptual Organization, and Working Memory Indexes require accurate responses, and the patient is penalized less for time of completion. An excep tion to this is the Block Design test in which the correct response is recorded, but more points are awarded with a more rapid correct response. The Processing Speed Index provides a measure of information processing efficiency. In the postacute phase, therapists may elect to improve either accuracy or speed, depending upon the task to be mastered. Those patients with whom behavioral impulsivity and disinhibition may be problematic may ben efit from an approach that focuses on pacing the speed of response and inserting verbal selfcueing methods between the instruction and execution of the task. In making job modifications, the patient with brain injury may require that tasks be done on a projectdriven basis rather than a timetowork product basis, thus with reduced demands for speed of processing perhaps with an emphasis on accuracy. Recent memory functioning I used to spend all my time lying on my right side or sitting up for a little while trying to recall some of my past. Zasetsky Content of the neuropsychological evaluation 621 Recent memory is a multifaceted concept covering verbal, visual, and tactile­spatial domains. Memory can include episodic (eventrelated memory) and procedural (recall and reproduction of actions) aspects. For a comprehensive dis cussion of the neuropsychology of memory, see Squire and Schacter,42 Tulving and Craik,43 and Addis, Barense, and Duarte. Recent memory ability and new learning skills are inti mately linked, seen in the neuropsychological evaluation of these skills and also observed in everyday situations. Those with selfawareness deficits may not pay attention to information that could be judged to be important to recall at a later time. Those with disinhibition syndromes may not have the sustained attention necessary to register important information, and therefore, storage of such relevant information may be incomplete. Another aspect of memory that is not easily ascertained is prospective memory capacity. This form of memory also requires executive abili ties, including planning, anticipation, and selfmonitoring functions. Although many tasks examine recent declarative or episodic memory functions, few are geared to determine prospective intent. Two available tests that measure this aspect of memory include the Cambridge Prospective Memory Test and the Rivermead Behavioural Memory Test-Third Edition, and these are noted in Table 31. In clinical practice, recent memory tests assess imme diate recall of information for which efficient encoding of information is required. Delayed recall of ini tially presented material across 20 to 30minute time inter vals are common among memory tests. The examiner will usually administer other neuropsychological tests/tasks in the interval time between the immediate and delayed recall portions of the test, thus introducing an element of alternat ing, focused, and divided attention. Recognition trials in which the patient must choose among several verbal or visual stimuli to identify what was initially presented assess recall accuracy, false positive, and false negative rates. Recall trials often require rote retrieval of information and are generally more difficult for the patient. Verbal and visual stimuli may be placed within a context such as a paragraph story that has a beginning, middle, and ending; visual stimuli may be recognizable objects or pictures. Other recent mem ory tests may require the patient to impose an organizing principle.

What is instead required is a technique that addresses the impairment in attention itself rather than merely its manifestations symptoms enlarged spleen lincocin 500mg amex. Additionally, the same is true for individuals who display perseverative behaviors. The term perseveration does not adequately communicate the complex essence of the disorder. A holistic approach to outlining the deficit is beneficial in the assessment and treatment process. Although there are several manners in which to address attention, designing a bottom-up therapeutic program allows for a developmental approach to building attention skills. Taking this approach with all individuals exhibiting attentional deficits ensures that all skills have been acquired in a developmental and sequential fashion, setting the foundation for higher-level cognitive processes. Therapeutic activities addressing categorization, memory, visual and auditory processing, direction following, shifting, and problem solving can be performed to address the development of attentional skills. Physical or concrete tasks, such as sorting, scanning, and direction following, should be initiated first. Individuals with very poor attention may start with simple auditory sustained attention or vigilance tasks. Such tasks require the individual to listen to a string of stimuli targeting a specific number, letter, or word for short periods of time. For example, the individual can sort picture cards or hardware pieces into different categories. Visual scanning or vigilance tasks can involve searching magazine articles for a target word. Again, once this task has been mastered, the addition of multiple targets further challenges attentional skills. Auditory scanning activities involve listening to stories or passages and indicating a targeted response for a designated word and then increasing the number of target words. Basic level strategies to improve accuracy on concrete tasks include teaching systematic scanning, double-checking work, and increasing awareness of attention deficits. Consistency must be established prior to moving the individual to a higher distractor level. Once the individual exhibits the ability to consistently perform tasks in a quiet and controlled environment, a hierarchy of distractors should be introduced. Then, the individual can be moved from the controlled environment to a familiar environment with minimal distractors. This might simulate a person in a living or family room, providing the individual with the opportunity of a chance conversation and/or the presence of others nearby. To further challenge the attentional system, the next level should require the individual to perform tasks in a highly distractible, familiar setting. Once individuals demonstrate the ability to maintain attention in a distracting environment with good accuracy on concrete tasks, more mental or abstract tasks can be implemented. Working memory tasks, such as reordering a string of random numbers from smallest to largest or in reverse order, are more cognitively challenging. These tasks involve listening to a string of words and identifying items that fit into a designated category. This task involves the individual viewing a card with three rows of letters for a brief period of time (2 seconds) and then being asked to recall a specified row. The generalization of quick visual processing can be facilitated through setting up a scene in a room and having the individual enter the room for a brief amount of time. Upon leaving the room, the individual would be required to recall as many details as possible. Next in the hierarchy of attention is alternating attention, which refers to the ability to alternate attention from one activity to another with the least amount of interference to sensory stores, task sequencing, and task accuracy. Basic level attention should be relatively intact prior to addressing cognitive shift skills. Cognitive shift activities should adhere to the concepts of task complexity and presentation of external sensory stimuli. Activities should begin with two simple physical tasks, requiring the individual to shift from one activity to the other and back. Data collection includes response time to shift between tasks and accuracy of task completion.

The individual performs the math calculations while simultaneously monitoring time medicine abuse lincocin 500 mg order on line. These tasks can also be performed with the hierarchy of distractors presented in Table 27. The highest level of attention is divided attention, which requires the ability to attend to two or more different tasks simultaneously. Individuals divide their attention while driving, taking notes in class, performing household chores while watching television, etc. Divided attention can be addressed in a variety of ways, such as performing previously mentioned concrete and abstract tasks while simultaneously answering a series of questions differing in levels of complexity. For example, the individual may be required to sort hardware pieces into categories while simultaneously responding to yes/no or open-ended questions of varying complexity. The therapist can document response time to complete the sorting task, the percentage of correct responses, and any delay in responses to questions. In this way, processing speed can be monitored not only for task completion, but also for frequency of delayed responses. A perseverative response may be characterized as an inability to shift a focus of attention among perceptual features. Therapeutic activities that decrease perceptual salience and establish the use of iconic and symbolic feature identification skills usually result in a reduction of perseverative responses. For example, the therapist may present an object to an individual and direct his or her attention to various perceptual features of the object such as color, shape, construction, etc. Some perseverative behaviors, however, may be a result of perceptual salience in other sensory domains, such as self-abuse as a result of sensory integration deficits. Treatment for improving perceptual salience will be discussed later in this chapter. Attentional deficits also include problems with vigilance, referring to the ability to sustain a focus of attention and regulate perception of incoming information for a particular set of features. For an individual to be successful, he or she must first be able to quickly take in large amounts of visual and/or auditory information, resisting distractions of extraneous stimuli, and then be able to filter that information for the preferred feature(s). This process requires quick processing speed and increasingly abstract cognitive distance skills. Thus, therapy should address sustaining attention in a multisensory environment and building cognitive distance skills. Awareness of deficit and self-monitoring techniques should be explored and implemented. For example, prior to the initiation of a task, it would be appropriate to ask the individual to predict his or her success on the specific Therapeutic intervention 499 task. Based upon the difference between predicted and actual performance, strategies for improving attention can be discussed. Memory Memory is a component of cognition that entails the ability to encode, store, retain, and recall information. In describing memory, the typical metaphor used is that of a filing cabinet or computer that can store many folders and files. In the late 1960s, Richard Atkinson and Richard Shiffrin first described their model of memory as a sequence of three stages, from sensory memory to short-term/working memory to long-term memory as opposed to a single/unitary process. It acts as a kind of buffer for stimuli received through the five senses that are retained accurately but very briefly. For example, prior to the days of the Internet, one could dial the operator to find the phone number of a store. Once the operator stated the seven digits, that information was in memory until the last number in the phone number was dialed. Therapeutic tasks that address auditory or visual sensory memory include echoic store and iconic store tasks. The echoic store task utilizes cognitive processes, including attention, working memory, auditory recall and processing speed. In this task, numbers are presented verbally in a random order and the individual is required to organize the numbers from smallest to largest.

The resulting convulsive behavior evolves through stages that are highly reproducible from animal to animal and may be graded by levels of behavioral severity symptoms dizziness nausea generic 500 mg lincocin overnight delivery. At stage 3, the animal displays clonus jerking of forelimbs, and at stage 4, there is forelimb clonus with rearing onto hind limbs. The fifth and most severe stage consists of forelimb clonus with rearing and falling. Electrical kindling of seizure activity induces neuronal changes within the brain that result in more severe generalized seizures from a stimulus that initially produced only focal seizure activity. Numerous transient and long-term changes occur during and as a result of electrical kindling with the most dramatic being seen within the excitatory and inhibitory amino acid transmitter systems. Because sequelae of brain injury also elicit aberrations in the excitatory and inhibitory tone,70 using the kindling model to produce postinjury epileptogenesis is a useful tool, particularly in combination with focal cortical damage. In this model,94,95 injury severity is controlled using a reproducible focal cortical lesion113,114 that induces behavioral deficits in animals similar to those seen in humans with brain injury. In our laboratory, we observed a 37% decrease in stage 5 seizure threshold following cortical lesion in comparison to fully kindled animals without lesions. Electrical kindling of the amygdala after focal cortical lesion is a useful and unique model as it allows for the study of the neurobehavioral impact of epileptogenesis (with and without anticonvulsant drug administration) while still controlling seizure timing, type, and number. Individuals with posttraumatic epilepsy pose a special case, in that they are neither patients with only a brain injury nor patients having only epilepsy. Thus, the treatment requirements for posttraumatic epilepsy extend well beyond those available for either the epilepsy or brain injury alone. Although many antiepileptic drugs may block fully kindled convulsions in animals, they do not prevent the kindling process and do not prevent the increases in seizure severity. Specifically, phenytoin and carbamazepine may block seizures, but they do not consistently prevent epileptogenesis from occurring. Administration of the alpha adrenergic receptor agonist, clonidine, can significantly retard the rate of evolution of kindled seizure stage but, by itself, does not block the fully established kindled seizure. Use of models of epilepsy, rather than acute seizures, holds great promise for future development of antiepileptogenic drugs. These models include the electrical kindling paradigm, studies in genetically seizure-prone animals, and models in which the focal insult. The question is, does this come at a cost to the traumatically brain injured patient For example, it was initially suggested that carbamazepine induced less cognitive impairment than phenytoin. To address these issues, it has been recommended that anticonvulsant prophylaxis be utilized in high-risk patients. For example, if diazepam is administered during the first 3 weeks after unilateral anteromedial cortex damage, recovery from somatosensory deficits is delayed indefinitely. As a caveat, however, when an anticonvulsant dose of vigabatrin was coadministered against subconvulsive kindled seizures, recovery was impeded. There are several potential mechanisms by which anticonvulsants may adversely affect the recovering brain. This condition of postinjury neuronal depression has been referred to as diaschisis,162 which is the temporary disruption of neuronal activity in undamaged areas functionally related to injured areas. Evidence that diaschisis occurs after brain injury has been well established with measures of blood flow, metabolism, electrical activity, and neurotransmitter levels. For this to be the case, the neurobehavioral consequences of seizures would need to be associated with improved recovery or no deleterious effect. Experimental data in animal studies suggest the effects of seizures are not uniform and greatly depend on seizure type, severity, and frequency. However, when the entire array of neural and functional consequences of seizures are considered, a complex yet fairly clear picture emerges that is dependent on the timing, type, and severity of postinjury seizures. For example, using an animal model of posttraumatic epilepsy (described above), it appears that the impact of seizures is bimodal: Convulsive seizures (stage 1) during the 6-day postlesion critical period are detrimental to the recovery process whereas subconvulsive seizures (stage 0) have no functional impact. Moreover, contralaterally kindled seizures exert no impact on recovery regardless of when they occur. We propose that the occurrence of early stage 0 kindled seizures after cortical lesion models early posttraumatic seizures, and the occurrence of early stage 1 kindled seizures after lesion models posttraumatic epilepsy. As such, our results suggest that the occurrence of early posttraumatic seizures does not adversely affect recovery from the brain injury, but early posttraumatic epilepsy blocks recovery completely.
