A major challenge was the number of different admission portals for these patients. In addition, although the survey was acceptable to the majority of patients (< 8% refused), it proved difficult to convince nursing staff to integrate such data collection into routine care, as the information gained did not appear relevant to their specific role. It comprises several existing measures, namely, the Rose Angina Questionnaire (Rose & Blackburn, 1968), the Rose Dyspnoea Questionnaire (Rose & Blackburn, 1968), the Fatigue and Vigour subscales of the Profile of Mood States (McNair et al. Cardiovascular dimension-specific measures Fifteen cardiovascular-specific measures focussing on a single symptom or dimension were also identified. Description of content and evidence for these measures are summarised in Appendix C. However, there was mixed evidence regarding its acceptability to patients, as reflected in response rates. Evidence for reliability, validity, responsiveness, and acceptability to patients was substantial; however, one study reported ceiling effects, and some studies had low response rates. Some of the other measures reviewed, such as the Cardiac Symptom Survey and the Heart Surgery Symptom Inventory, may also prove valuable if further evidence emerges. Choice of instrument may be influenced by whether short and medium-, or longer-term outcomes are the focus of investigation. If short and medium-term outcomes are the main object of attention, one of these surgery-specific measures could be the instrument of choice. The Duke Activity Status Index has considerable merit as a measure of cardiac patients’ capacity to engage in activities which are important to their QoL.

However, there exists a substantial amount of or four to six times that reported for community-dwelling individual variability because clearance is also highly depen elderly. Compared to the young-old, those in the middle involve single-dose evaluations in small samples of the young old or old age group were 33% less likely to have been pre old. Another issue is that many elderly persons are taking other potentially interfering drugs (Table 37. Within the same study, compliant clinic the theoretical basis for expecting age-related changes in drug patients experienced variability of approximately 20% (37). Drug concentration at the site interlaboratory variability in measurement of drug concentra of action determines the magnitude of both desired and toxic tions, although laboratories not following rigid quality control responses. The unbound drug concentration in serum is in standards may experience even larger amounts of variability. The variability for carbamazepine is on the when the drug is not highly protein-bound (less than 75%), or order of 25%, possibly due to its shorter half-life, which may when the ratio of unbound to total drug concentration increase sample time variability (38). This was confirmed in an analysis of ser tein-bound, and protein binding is frequently altered. Some patients experienced a difference in concen ing and a reduction in liver volume and blood flow (28–30). Interestingly, some had very little fluctuation and were protein) concentrations in the elderly may alter protein binding similar to that of the younger adults previously mentioned. Factors that contribute to this variabil goes saturable metabolism, which has the effect of producing ity in concentration must be identified and strategies should nonlinear changes in serum concentrations when the dose is be developed in order to minimize this phenomenon. Clinical studies in elderly patients have shown decreases in phenytoin binding to albu min and increases in free fraction. However, years of age) persons, 32 middle-aged (40 to 59 years of age) there is little data relating specifically to these drugs in the persons, and 26 younger adult (20 to 39 years of age) per elderly, and those that are available have been limited to the sons with epilepsy (45). Notably, these declined with age, and significantly lower values of Vmax elderly patients also experienced side effects at lower levels were seen in the elderly group compared to the younger compared with the levels in younger subjects (42). Other earlier and smaller studies have also A multicenter, double-blind, randomized comparison shown that phenytoin metabolism is reduced in the elderly. United Kingdom showed that the main difference between the Relatively small changes in dose (10%) are recommended two groups was the rate of dropout due to adverse events, when making dosing adjustments. Thus, in the elderly a with lamotrigine incurring an 18% dropout rate compared to starting daily dose of 3 mg/kg appears to be appropriate, that of carbamazepine which incurred a 42% dropout rate rather than the 5 mg/kg/day used in younger adults (46). Coumadin also has a very complicated interaction with phenytoin and often doses of both need to be manipulated (46). Carbamazepine Phenytoin has some effects on cognitive functioning, espe cially at higher phenytoin serum concentrations (48). However, Carbamazepine is effective for localization-related epilepsies, it is not known if the elderly will be more sensitive to this and thus has an efficacy profile appropriate for the elderly. Two studies In a study involving elderly persons, among the various of new-onset epilepsy in the community-dwelling elderly lifestyle, demographic, and health factors which contributed found carbamazepine to be as effective as lamotrigine, but to an increased risk, phenytoin was the only drug which was noted that it had a higher incidence of side effects (11,43). The apparent clearance of carbamazepine has been However, this study could not determine if this was due to reported to be 20% to 40% lower in the elderly as compared falls from ataxia or seizures, or was an effect due to bone to adults (52,53). These changes in carbamazepine phar effects profile, which may worsen cognition and depression, macokinetics indicate that lower and less frequent dosing in make it an undesirable drug for the elderly, especially in the elderly patients may be appropriate. Observed carbamazepine concen trations in the Birnbaum study were lower or below the sug Only a few studies have compared the pharmacokinetics of gested therapeutic range used in treating younger adults. As a result, and should be instructed to inform the physician whenever the desired clinical response may be achieved with a lower they are beginning a new medication, including any over-the dose. Because the and may significantly lower the concentration of carba serum elimination half-life may be prolonged, the dosing mazepine. If the albumin concentration has Carbamazepine has some effects on cognitive functioning, fallen or the patient’s clinical response does not correlate with especially at higher levels. However, it is not known if the total drug concentration, measurement of the unbound drug elderly will be more sensitive to this problem. Because of its effects on mood stabiliza bamazepine may cause imbalance and ataxia. One of the major con cerns with carbamazepine is its effect on sodium levels (54). Hyponatremia is a well-known phenomenon seen with carba Felbamate mazepine use, and may cause significant problems in younger adults, especially if there is polydypsia. The hyponatremia Felbamate is effective for localization-related epilepsies and associated with carbamazepine is more pronounced as a per appears to have a broader spectrum of effectiveness than some son becomes older (55). Elderly subjects had a lower mean clear a person is on a salt restriction diet or a diuretic. Felbamate is primarily metabolized by the liver and meters in the elderly will need to be studied. Carbamazepine is is known to have a number of drug–drug interactions, both also known to affect cardiac rhythms, and should be used cau inhibitory and inductive, and therefore may not be a good tiously, if at all, in persons with rhythm disturbances. In the elderly, however, the half-life may be longer, and Gabapentin slow-release formulations may overcome the need to dose multiple times each day and may overcome some of the side Gabapentin is effective for localization-related epilepsies, effect problems associated with a rapid time to a high peak and has an efficacy profile appropriate for the elderly. Gabapentin is not metabolized by the liver, but rather renally excreted; therefore, there are no drug–drug interac tions (60). Chapter 37: Epilepsy in the Elderly 465 Gabapentin has a short half-life that requires it to be given body clearance and an increased half-life up to 2. In the elderly, however, the half-life may longer in elderly subjects (age 61 to 88 years) who exhibited be longer due to a reduction in renal elimination. Levetiracetam also appears to withdrawal related to side effects was highest for carba have a favorable safety profile. Analysis of 3252 elderly per sons involved in studies of levetiracetam for epilepsy and Lamotrigine other conditions demonstrated that levetiracetam was well tolerated by the elderly (68). Lamotrigine is effective for localization-related epilepsies, and has an efficacy profile appropriate for the elderly. However, very few studies regarding lamotrigine and its effects on the Oxcarbazepine elderly have been published. Lamotrigine is primarily metabo lized by the liver using the glucuronidation pathway, which Oxcarbazepine is rapidly metabolized by first-pass meta unlike the P450 system, is thought to be less affected by age (61). The most extensive elderly oxcarbazepine study jects from the old-old age group showed that age did not affect involved low doses of oxcarbazepine given to 12 young and lamotrigine apparent clearance (62). Based on a study of 150 12 elderly healthy male volunteers and 12 young and 12 elderly subjects, the drop out rate due to adverse events was elderly female volunteers. At low doses of oxcarbazepine lower with lamotrigine (18%) than with carbamazepine (42%). Clinicians may want to consider other Oxcarbazepine can affect the cytochrome P450 system by factors when dosing elderly lamotrigine patients. However, oxcarbazepine appears to have a more creatinine ratio, weight, and phenytoin use (63). However, these drug inter Pregabalin action studies included very few elderly subjects. Levetiracetam has been approved as adjunctive therapy for partial-onset seizures in adults. Levetiracetam is extremely Tiagabine water soluble, which allows for rapid and complete absorp tion after oral administration.

The tiagabine, giving it a drug interaction profile similar to carba lack of drug interactions makes levetiracetam useful for treat mazepine. A major feature of tiagabine is its potency; usually, ing elderly epilepsy patients, particularly those patients who effective doses are 20 to 60 mg/day, and effective concentra have other illnesses and are taking other medications (65).

Investigating brain regions that may be specialized for perception of our species specific faces may shed light on the nature versus nur ture debate erectile dysfunction treatment injection cost order top avana uk. Or does our vast experience with faces provide the information processing abilities that are not specific to faces, but rather utilizes visual object perception networks Studying face process ing during development may help us determine how genetic predisposition interacts with experience.

Also, older children show more bilateral fusiform face area activation for faces as compared to houses than younger children, and the pattern of activation correlates with age (Aylward 500 15. Nevertheless, these studies indicate that, processes develop and mature, much more work is while older children show more focal activation than needed before we can claim to understand fully the younger children, they do not show adult-like pat intricacies of human face perception. Understanding emotional cues in Taylor reported that only the oldest group of children facial expressions is a vital aspect of social cognition (14–15 years) showed N170 patterns of response that in humans. And, even in this group, the cues is complex, however, and not well understood N170 response did not appear to be adult-like in dis in adults let alone in developing children. In this study, the children developmental path of emotional cues in face process were 10–12 years old. Lobaugh and colleagues used a ing is in its early stages: while these studies provide gender decision task for investigating emotional cues some useful early data for understanding how these in faces: the children were asked to decide if the face 4. The leagues attempted to understand the neural substrates differing tasks and techniques used in these studies of implicit recognition of emotional cues during face make an interpretation of the findings problematic in processing. First, Lobaugh and colleagues evalu spite of the fact that the two studies investigated very ated brain areas that were differentially responsive to similar processes, emotional cues in faces. These are shown in the investigations presented here provide early evi Figure 15. These areas were right fusiform/para dence for differing patterns of brain response in child hippocampal gyrus, which were more active in the hood when processing emotional cues in faces. Many face task, and bilateral superior temporal gyrus and more studies are needed in order to for us to under posterior temporal gyrus, which showed decreased stand fully the brain area and developmental path of activity in the face task. Some A second key finding was that brain activation to important aspects of the future studies may entail negative emotions (disgust, fear) was stronger than determining if boys and girls process emotional cues responses to positive (happiness) or neutral emotions in a similar way and assessing if children pay more (Figure 15. The strongest responses were to faces attention to certain aspects of faces (such as eyes) as with expressions of fear. One central finding from Taylor and Lobaugh and colleagues tell us about a variety of data sources (histological, pathological, how children understand complex emotional cues in neuroimaging) is that the cortical regions subserving faces We have a wealth of behavioral data showing study of hemodynamic changes) are quite different a similar pattern in tasks that tap more complex and in just what brain responses they are able to measure. Putting these two bodies of informa (4–15 years), while the other had a small sample (10) tion together in order to map brain development onto 502 15. The first pattern most strongly distinguished disgust (blue, negative task weight) from fear (red, positive task weight) and, to a smaller extent, from surprise (cyan) and happiness (gray). Yellow/red: regions where the response to fear was greater than that to disgust; blue: regions where the response to disgust was larger than that to fear. This pattern most strongly distinguished disgust and fear (blue and red, positive task weights) from sadness (green, negative task weight). Yellow/red: regions where the response to disgust and fear was greater than that to sadness; blue: regions where the response to sad faces was larger than that to disgust and fear. Consider the hypothesis that being worked out in adults, with less known about the some brain systems, such as language, have a strong patterns of emergent language. If there is early insult to those tapping attentional, planning, and working memory pre-specified regions, will the infant develop language systems.

In this way, early ‘baseline’ where the perinatal damage is limited to a circum measures can be taken and then the development and scribed region (Figure 15. Finally, new experimental design approaches the types of cases that we will focus on in this section: with young infants are demonstrating that babies know early, focal, unilateral brain insult. New advances in measuring infant cognition and mapping the relevant brain activity will provide important insights into the developmental changes occurring in the first year of life. Right: A is especially important when assessing the long-term deep lesion involving subcortical regions. Stiles and colleagues have followed the cognitive development of several hundred children with perinatal brain damage since 1989. Much of the focus of the investigations by Stiles and colleagues in the San Diego Longitudinal Project has been on language development in children with perinatal brain damage. Examples of memory reproductions of hierarchical form ing deficits, this pattern is quite different with infants stimuli by adult stroke patients with either right or left hemisphere who suffer perinatal brain damage. Center of the figure: patients with right hemisphere damage typi of word comprehension at 9–12 months and word pro cally produce the local (detailed) aspects of the stimulus but omit duction at 12–15 months, by the age of 5 years, these the global (overall) aspects of the stimulus: in this case, the ‘ M ’ or children have largely ‘caught up’ in linguistic abilities. Right side of the figure: patients with the important finding, however, is that when tested left hemisphere damage typically produce the global aspects of the stimulus but omit the local aspects of the stimulus. These children with early brain damage do ultimately achieve language competence, greater left hemisphere occipital-temporal activation but the evidence provided by the longitudinal studies for local processing (Figure 15. Thus, while the children do acquire vation for both global and local processing in the left many skills and proficiencies with respect to language, (undamaged) hemisphere (Figure 15.
