Observations on the neurochemistry of dementia with Lewy bodies (DLB) have suggested that cholinesterase inhibitors (ChEIs) might be beneficial in treating some clinical symptoms of DLB. A 24-week, multicenter open-label study was designed to assess the safety and efficacy of the ChEI galantamine in patients with DLB, and an interim analysis of results was performed at 12 weeks. Efficacy analyses were performed on data from 25 patients. Scores on the Neuropsychiatric Inventory (NPI-12) improved (decreased) by 7.52 points over the 12 weeks (marginally significant, p = 0.061). NPI-12 scores decreased by half in 12 of the 25 patients. Highly significant improvement was observed in scores on the NPI-4 subscale (delusions, hallucinations, apathy, and depression: p = 0.003). Scores on the Clinician's Global Impression of Change (CGIC) improved by 0.95 points (significant, p = 0.02). Improvements also were found in secondary efficacy variables, including cognitive, functional, activities of daily living, sleep and confusion assessments. Motor scores, as measured by the UPDRS motor subscale, showed mild improvement, which demonstrates that galantamine has no adverse effect on parkinsonian symptoms. Adverse events generally were transient and of mild-to-moderate intensity. Two of the 25 patients discontinued galantamine because of nausea and anorexia. One serious adverse event was recorded, but it was judged to be unrelated to the study medication.

This article reviews the piperidine derivative, donepezil hydrochloride (E2020, Aricept), a reversible central acetylcholinesterase inhibitor currently approved for treatment of mild-to-moderate Alzheimer's disease. Donepezil is well absorbed orally, unaffected by food or by time of administration; it reaches therapeutic levels in doses of 5-10 mg/day and peak plasma concentrations are obtained 3-4 h after oral administration. A single bedtime dose is recommended due to the long elimination half-life of the drug (70 h). Donepezil does not cause liver toxicity or significant drug interactions and is relatively well-tolerated. Initial side effects include nausea, vomiting, diarrhoea, insomnia, muscle cramps, fatigue, anorexia and syncope. Caution is advised in patients with bradycardia. Long-term use of donepezil in AD has been found to delay nursing-home placement and to result in caregiver respite. Donepezil also slows deterioration of cognition and global function in patients with moderate-to-severe AD, with improvement of abnormal behaviours. In addition to AD, donepezil demonstrates significant improvement in cognition, global function and activities of daily living in comparison with placebo-treated patients with vascular dementia and has potential therapeutic benefit for other neurological conditions.

The records of 38 elderly patients with hip fracture admitted to our hospital between January and December 2002 were retrospectively reviewed to determine the incidence and outcomes of medical complications. The mean age was 84.5 +/- 6.83 years old, 32 women and 6 men. 27 patients (71%) suffered from dementia. Of the 38 patients, 33 (86.8%) had one and more underlying diseases: hypertension 29, cerebrovascular episode 7, congestive heart failure 5, diabetes mellitus 4, gastric ulcer or chronic gastritis 3, ischemic heart disease 4, depression 2. Three patients had a past history of hip fracture. Fourteen patients (37%) developed medical complications after hip fracture, most frequently pneumonia (64%). Other complications were dizziness, nausea, congestive heart failure, choledocholithiasis, and GI tract bleeding. Eight patients who suffered pneumonia cancelled elective surgery. Severity of pneumonia was mild in 2, moderate in 5, and severe in 2. Both cases with severe pneumonia died in hospital. Patients with pneumonia (pneumonia group) were significantly older and had more severe dementia than patients without pneumonia (non-pneumonia group). Although there were no significant differences in physical ability between the two groups before admission, physical ability on discharge was lower in the pneumonia group. The pneumonia group had a significantly longer mean hospital stay than the non-pneumonia group. Our results suggest that the prevention of pneumonia is necessary to improve the outcome of hip fracture.

Normal pressure hydrocephalus (NPH) is characterized by insidious onset and gradual development of the triad of gait disturbance, dementia, and urinary incontinence. Nausea, vomiting, and signs of increased intracranial pressure do not occur. A 71-year-old male patient was scheduled for total knee replacement due to osteoarthritis of right knee joint. No neurological symptoms and signs except mild forgetfulness were detected during physical examination following admission. Due to operational mistakes, the anesthesiologist was informed that the surgery was cancelled just after completion of induction of general anesthesia. The patient was allowed to emerge from anesthesia. Unfortunately, his consciousness became drowsy the next morning. After a series of examinations, he was at last diagnosed as a case of NPH principally by the brain computed tomography scan. So he was scheduled again but this time for vetriculoperitoneal (V-P) shunt. The patient regained consciousness after V-P shunt. From this case, we learned that NPH may remain in concealment in the patients we contacted in our daily practice. A vigilant physician should keep in mind that the presentation of gait disturbance, dementia, and urinary incontinence in a patient may indicate the likelihood of NPH.

Cognition in transgenic mouse models of Alzheimer's disease (AD) has been predominantly characterized in explicit spatial orientation tasks. However, dementia in AD encompasses also implicit memory systems. In the present study a line of transgenic mice (TgCRND8) encoding a double mutated allele of the human amyloid precursor protein (APP) genes was evaluated in an implicit associative learning task of conditioned taste aversion (CTA). CTA is a form of Pavlovian classical conditioning, in which a mouse learns to avoid a novel taste of saccharine (conditioned stimulus) paired with an experimentally induced (systemic injection of lithium chloride) nausea (unconditioned stimulus). In contrast to conditioned non-Tg mice, TgCRND8 APP mice developed weaker aversion against saccharine and quickly increased its consumption in repeated tests. These results indicate that TgCRND8 mice show a significant impairment not only in explicit spatial memory, as has been previously shown [Nature 408 (2000) 979], but also in implicit memory. Control experiments confirmed that TgCRND8 and non-Tg mice had comparable taste sensitivities in response to appetitive as well as aversive tastes. The study suggests that the CTA paradigm can be a sensitive tool to evaluate deficits in implicit associative learning in APP transgenic mouse models of AD.

Pellagra is a systemic disturbance caused by a cellular deficiency of niacin, resulting from inadequate dietary nicotinic acid and/or its precursors, the essential amino-acid tryptophan. In Europe and North America cases of pellagra are rarely encountered, but in some developing countries this disease is frequent, and is the most frequent clinical feature of nutritional deficiency of adult. The principal causes of pellagra are: nutritional niacin deficiency; chronic alcoholism; gastro-intestinal malabsorption; some medications (5-fluoro-uracil, isoniazid, pyrazinamide ehtionamide, 6-mercaptopurine, hydantoins, phenobarbital and chloramphenicol). The diagnosis of pellagra is based on the patient's history and the presence of "3 D syndrome": dermatitis, diarrhea, and dementia. The dermatitis caused by pellagra is a bilaterally symmetrical erythema at the sites of solar exposure. The dermatitis begins in the form of an erythema with acute or intermittent onset gradually changing to an exsudative eruption on the dorsa of the hand, face, neck, and chest with pruritus and burning. Acute dermatitis of pellagra resembles sunburn in the first stages, sometimes with vesicles and bullae. The gastro-intestinal disturbances are: anorexia, nausea, epigastric discomfort and chronic or recurrent diarrhea. Anorexia and malabsorbative diarrhea lead to a state of malnutrition and cachexia. Stools are typically watery, but occasionally can be bloody and mucoid. Neuropsychologic manifestation included photophobia, asthenia, depression, hallucinations, confusions, memory loss and psychosis. As pellagra advances, patient become disoriented, confused and delirious; then stuporous and finally die. Pathological changes in the skin is non-specific, there are no chemical tests available to definitively diagnose pellagra. However low levels of urinary excretion of N-methylnicotinamide and pyridone indicates niacin deficiency. The treatment of pellagra consisted to exogenous administration of niacin or nicotinamide cures. Topical management of skin lesions with emollients may reduce discomfort. The therapy should also include other B vitamins, zinc and magnesium as well as a diet rich in calories. The prevention is based in the nutritional education (food sources of niacin: eggs, bran, peanuts, meat, poultry, fish, red meat, legumes and seeds), and the eviction of alcohol.

Reminyl (galantamine)-- a cholinesterase inhibiting component--was used in treatment of 15 patients with dementia featured by the presence of Levi bodies in brain neurons. The treatment duration was 16 weeks with elevation of the drug dosage every 4 weeks--from 8mg to 12 mg twice a day. Treatment evaluation was conducted clinically and by psychometrical tests and scales. Reminyl improved patient's state reducing cognitive, behavioral and psychotic disturbances. The highest effect was achieved in 2/3 patients. Side-effects (nausea, dizziness, dyspepsia, general sickness, etc) were observed in 47% cases. Only in 2 patients they caused treatment withdrawal. The absence of aggravation of extrapyramidal disorders is emphasized.

The objective is to evaluate the efficacy of galantamine when a slow titration regimen is employed in Thai Alzheimer's disease (AD) patients with or without cerebrovascular disease and vascular dementia (VaD). A 6-month, multicentre, open-label, uncontrolled trial was undertaken in 75 AD patients. Eligible patients received an initial galantamine dose of 8 mg/day and escalated over 5-8 weeks to maintenance doses of 16 or 24 mg/day. Primary efficacy measures were AD Assessment Scale-cognitive subscale (ADAS-cog) and the Clinician's Interview-Based Impression of Change-Plus version (CIBIC-plus). The Behavioural Pathology in AD Rating Scale (BEHAVE AD), the AD Cooperative Study Activities of Daily Living Inventory and Pittsburgh Sleep Quality Index were the secondary efficacy variables. Analyses were based on the intent-to-treat population. Treatment with galantamine showed significant improvement in cognition on the ADAS-cog and CIBIC-plus at month 6. Galantamine showed favourable effects on activities of daily living. Behavioural symptoms and sleep quality were also significantly improved (p < 0.05). Galantamine was well tolerated. The adverse events were mild-to-moderate intensity. The most frequent adverse events commonly reported were nausea (16.4%), dizziness (9.6%) and vomiting (6.8%). The results of this study may be consistent with galantamine being an effective and safe treatment for mild-to-moderate AD patients with or without cerebrovascular disease and VaD. Flexible dose escalation of galantamine was well tolerated. The daily maintenance dose of galantamine was 16 mg/day, followed by a back up dose of 24 mg/day.

Inhibition of acetylcholinesterase improves symptoms of dementia in patients with Parkinson's disease (PD). Dementia in PD has a cumulative incidence of up to 80% and is mainly caused by a distinct cholinergic deficit. Objectives of this investigator initiated multicenter open label trial were to confirm the efficacy of donepezil in the treatment of dementia in PD patients and to investigate the tolerability and safety of donepezil. The Mini Mental State Examination (MMSE)-score significantly increased in patients, who finished the trial. A detailed analysis of the various items of the MMSE revealed, that only task performance of orientation and recall significantly improved. Scores of the short syndrome test and the Clinical Global Impression Scale improved, motor impairment did not increase. Only 14 out of 24 PD patients finished the trial due to predominant onset of vomiting, nausea, dizziness and confusion. This may result from the titration regime of donepezil, that allows only 5 and 10 mg dosages. Participants with premature study termination had a significant longer duration of PD, less motivation and sleep disturbances at night. Treatment with donepezil was only effective in PD patients with dementia, who experience nearly no side effects from the drug.

Nursing homes have taken on more and more the character of a hospice where palliative competence has significantly become more important. The aim of palliative treatment is not to heal but to control the symptoms during the final stage. The treatment of pain is definitely the main priority. Diagnosing and estimating the severity of the pain are basic requirements of an effective analgesic treatment. In addition to the pain, there are other symptoms such as nausea and emesis, dyspnoea, death rattle,fear, delirium and obstipation in the final stages of a disease which should be controlled very carefully. Not only patients suffering from cancer, but also very sick multimorbide patients and those suffering from dementia in geriatric environments will profit from palliative care.
