Case ReportsAnticholinergic drug-induced delirium in an elderly Alzheimer's dementia patient.
Drug-induced delirium is a common matter in the elderly and anticholinergics, together with a number of different drugs, may significantly contribute to the delirium onset, especially in demented people. We report a case of a probable anticholinergic drug-induced delirium in an elderly patient. An 80-year-old man with Alzheimer's dementia presented with wandering, depressed mood with crying, somatic worries, anedonism and suicide recurrent ideas. ⋯ The patient began a treatment with quetiapine 25mg/day for two days, then twice a day, and infusion of saline 1000 ml/day for two days; psychiatric symptoms gradually diminished and therapy with galantamine was begun. We postulate that this clinical report is suggestive for an anticholinergic drug- induced delirium since the Naranjo probability scale indicated a probable relationship between delirium and drug therapy. In conclusion, a complete geriatric, pharmacological, and psychiatric evaluation might be necessary in order to reduce the adverse drug reactions in older patients treated with many drugs.

Conversion of mild cognitive impairment to dementia in elderly subjects: a preliminary study in a memory and cognitive disorder unit.
Prevalence and incidence of predementia syndromes vary as a result of different diagnostic criteria, as well as different sampling and assessment procedures. Mild cognitive impairment (MCI) is thought to be a prodromal phase of dementia and therefore highly predictive of subsequent conversion. The aim of our study was to investigate the risk of conversion to dementia for different MCI subtypes diagnosed according to standardized and recently revised criteria (amnestic; impairment of memory plus other cognitive domains; nonamnestic). ⋯ The possible role of cortical atrophy and low folate in the conversion from MCI to dementia could have important implications, because both conditions are easily identifiable. Moreover, low folate status is potentially amenable to therapeutic options. Although discouraging with respect to the clinical usefulness of currently available MCI criteria, our results raise the possibility that defining a protocol of multiple clinical risk factors may be useful in identifying MCI individuals at increased risk of conversion.

Comprehensive geriatric assessment in female elderly patients with Alzheimer disease and other types of dementia.
The most visible manifestation of dementia is the progressive inability to activities of daily living (ADL) and to instrumental activities of daily living (IADL). The comprehensive geriatric assessment (CGA) is the validated and recommended instrument to a correct evaluation and decision making in elderly patients. To judge if the decline in cognitive functions is associated with a worsening in functional, emotional and clinical status measured by CGA, we also compared CGA in the same patients stratified for mild, moderate and severe dementia. ⋯ Patients with severe cognitive impairment are more likely to be dependent at ADL and IADL; to present a larger number of comorbidity and geriatric syndromes; to have lower !evels of Hb and higher levels of CR; to be in a worse nutritional status and to take a larger number of drugs. Polypharmacy maybe related to high comorbidity but the risk of irrational drug use should be evaluated. We suggest single testing with CGA as an effective tool providing a comprehensive assessment of elderly, and able to detect unaddressed corrigible problems.

Affective, behavior and cognitive disorders in the elderly with chronic musculoskelatal pain: the impact on an aging population.
Chronic musculoskeletal pain is a common, disabling condition that affects at least one in four elderly people. Figures are much higher in nursing homes, in which as many as 45-80% of residents has pain that contributes to functional impairment and decreased quality of life. Multiple comorbidity, under-reporting of symptoms and cognitive impairment make pain evaluation often difficult. ⋯ In a large Italian home care study, age of 85 years or more and low cognitive performance were predictors of failing to receive adequate analgesics. However, most patients with cognitive impairment and even those with severe dementia can be assessed using one of the available pain-intensity scales (verbal or not verbal). Structured programs are needed for routine pain assessment and treatment in older people.
