Vascular dementia can be performed quickly (1 minute per scan) and simply, is associated with a mottled, uneven, patchy appearance, Barber et al. In PD, the blood flow in basal ganglia is decreased, which suggests that at least in some cases relative preserva- and when PD is associated with dementia, bilateral parietal tion of the hippocampus and medial temporal lobe may changes similar to those seen in AD are reported (96,97). Sample medial temporal lobe In the few SPET studies of DLB, patterns of blood flow images are shown in Fig. The reason for this variability changes similar to those of AD have been found, although in temporal lobe atrophy in DLB is unknown, although Donnemiller et al. Perfusion of the medial However, although cross-sectional imaging may be helpful temporal lobe may be less impaired in DLB than in AD in some cases, it clearly is not diagnostic. It is yet to be (100), consistent with the structural imaging findings de- scribed above of preservation of the same structures in DLB. The more powerful, although still research-based, use of SPET involves the use of specific ligands for different neurochemical systems. Ligands have been developed for presynaptic and postsynaptic dopaminergic and cholinergic systems. However, one disadvantage of CIT is that imaging has to be delayed for 24 hours after injection. Coronal magnetic resonance imaging slices of pa- that a ligand with faster imaging kinetics, FP (fluoropropyl)- tients with Alzheimer disease (AD) and dementia with Lewy bod- CIT, can distinguish DLB from AD (103).

In contrast, 123 the appearance of the medial temporal lobe in the subject with strated with [ I]iodobenzamide, has been reported in DLB DLB is normal for age.

In summary, current evidence ably high risk of precipitating or exacerbating hallucinations suggests that SPET studies of blood flow show similar ap- and confusion. In addition, most of these agents can cause pearances in DLB and AD, although SPET may still be or worsen orthostatic hypotension and lead to an increased useful in distinguishing DLB, like AD, from frontal lobe incidence of falls.

New chemical imaging tech- sessed, avoidance of these drugs in DLB patients would niques, although not yet clinically available, show great seem prudent. Indeed, for a DLB patient presenting with promise in differentiating DLB from other disorders and parkinsonism, in whom dementia and neuropsychiatric are an exciting area of current research. TREATMENT At a practical level, the antiparkinsonian drug with the Neuropsychiatric Symptoms best risk-to-benefit ratio currently available for the treat- ment of extrapyramidal signs in DLB is levodopa. However, Some of the key clinical features of DLB are similar to those although the efficacy of levodopa for the treatment of PD induced in normal subjects by anticholinergic, specifically is beyond question, how effective is this drug in the manage- antimuscarinic, agents. The evidence regarding the responsiveness sion, and visual hallucinations are recognized effects of anti- of DLB patients to levodopa is conflicting. Some reports cholinergic drug toxicity, and cumulative effects of subcorti- suggest that up to 100% of patients with DLB may improve, cal and cortical cholinergic dysfunction probably play a but the numbers of patients have usually been small in these major role in the spontaneous generation of similar fluctuat- series, and the degree of functional change and duration of ing symptoms in DLB. As discussed in the earlier section on the response have not been specified (39,40). Furthermore, neurochemical clinical–pathologic relationships, reductions the effects of levodopa therapy on neuropsychiatric symp- in choline acetyltransferase are correlated with cognitive im- toms are poorly documented in this group. Given the post- pairment (75), and hallucinations may be related to hypo- synaptic changes in dopamine D2 receptors noted in post- cholinergic and (relatively) hypermonoaminergic neocorti- mortem studies, it might be postulated that levodopa cal neurotransmitter function (80). Clearly, a number of Several reports have indicated that patients who respond issues regarding the efficacy of dopaminergic treatment in well to cholinesterase inhibitor treatments are more likely DLB have not been resolved, and further trials are in to have DLB than AD at autopsy (106,107). Case reports suggest that cholinesterase prescribing neuroleptic medications, which are the mainstay inhibitors can reduce psychotic symptoms in DLB (108), of antipsychotic treatment in other groups of patients.

They occur in It is possible that cholinergic drugs may emerge as the 40% to 50% of DLB patients treated with neuroleptics antipsychotic treatment of choice in dementing diseases of the elderly, such as DLB. Not only are typical neuroleptics and are associated with a twofold to threefold increase in inappropriate (23); according to more recent reports, so are mortality.

The guideline will provide recommendations for good practice that are based on the best available evidence of clinical and cost effectiveness. The statements in each NSF reflect the evidence that was used at the time the Framework was prepared. The clinical guidelines and technology appraisals published by the Institute after an NSF has been issued will have the effect of updating the Framework. The NSF for Renal Services (2005) is of particular relevance to this guideline. In an important minority of people, CKD will develop into established renal failure (ERF), necessitating treatment by dialysis and/or a kidney transplant (collectively known as renal replacement therapy, RRT) for continued survival. For a small minority of people with 4 Appendix B: Scope of the guideline significant associated comorbidity conservative management (i. Regular testing of high-risk groups (people with diabetes, hypertension, cardiovascular disease or known kidney disease, and the elderly) can give an early indication of renal damage, thus allowing the delivery of interventions at an early stage. However, the diagnosis is often delayed or missed due to a lack of specific symptoms until CKD is at an advanced stage. Factors associated with progression of CKD and with increased cardiovascular risk are similar and targeting of these risk factors may both reduce CVD in people with CKD and reduce progression of CKD to end stage renal failure.
