In AD patients with symptoms of psychosis, agitation, or aggressive behavior, medications can have a small but significant impact on caregiver burden.
-
Among 14 placebo-controlled trials of elderly patients with dementia reporting a total global outcome score that includes symptoms such as psychosis, mood alterations, and aggression, small but statistically significant effects sizes ranging from 0.12 and 0.20 were observed for aripiprazole, olanzapine, and risperidone.
-
71/100
There was no difference between groups in time to emergence of agitation or psychosis (Cox proportional hazard ratio, 0.96; P = .88).
-
Two phase 3 studies evaluated the efficacy and safety of rosiglitazone (RSG), a type 2 diabetes treatment, in an extended release (RSG XR) form as adjunctive therapy to ongoing acetylcholine esterase inhibitor (AChEI) treatment in AD (REFLECT-2, adjunctive to donepezil; REFLECT-3, to any AChEI).
-
75/100
Simvastatin had no benefit on the progression of symptoms in individuals with mild to moderate AD despite significant lowering of cholesterol.
-
Decreases in depression scores at 13 weeks did not differ between 111 controls and 107 participants allocated to receive sertraline (mean difference 1·17, 95% CI -0·23 to 2·58; p=0·10) or mirtazapine (0·01, -1·37 to 1·38; p=0·99), or between participants in the mirtazapine and sertraline groups (1·16, -0·25 to 2·57; p=0·11); these findings persisted to 39 weeks.
-
These data suggest a revision of the original ADAPT hypothesis that NSAIDs reduce AD risk, as follows: NSAIDs have an adverse effect in later stages of AD pathogenesis, whereas asymptomatic individuals treated with conventional NSAIDs such as naproxen experience reduced AD incidence, but only after 2 to 3 years.
-
Ten weeks of treatment with PF-04494700 was safe and well tolerated in patients with mild-to-moderate Alzheimer disease, indicating the feasibility of a larger long-term efficacy trial.
-
Naproxen may attenuate cognitive decline in slow decliners while accelerating decline in fast decliners.
-
Summary results for patients with mild AD were obtained by contrasting the summary results for patients with mild or moderate AD with the summary results for the subset of patients with moderate AD.
-
The primary efficacy analysis did not show cognitive benefit with huperzine A 200 μg BID.
-
Subjects receiving the activity specific exercise program improved in ability to perform transfers, whereas subjects in the other 2 groups declined.
-
Type 2 diabetes is a risk factor for Alzheimer's disease, most likely linked to an impairment of insulin signaling in the brain.
-
Forecasted outcomes are compared with outcomes observed on candidate drugs, thus replacing a concomitant placebo group.
-
AF ablation patients were less likely to have diabetes, but were more likely to have hypertension, HF, and significant valvular heart disease.
-
The primary planned analyses did not show a significant treatment effect, but were confounded by unexplained variance.
-
The current drug treatment for Alzheimer's disease (AD) is only partially and temporary effective.
-
Homocysteine lowering in dementia patients did not significantly reduce global cognitive decline.
-
Poor vitamin D nutrition is linked with dementia, but vitamin D has not been tested in a randomized controlled trial (RCT) in Alzheimer's disease (AD).
-
Donepezil and antidepressant therapy temporarily improved global cognition (treatment × time interaction, F₂,₂₁₆ = 3.78; P = .03), but effect sizes were small (Cohen d = 0.27, group difference at 1 year).
-
A high incidence of fractures, particularly of the hip, represents an important problem in patients with Alzheimer disease (AD), who are prone to falls and have osteoporosis.
-
The 59 recruiting sites for the Alzheimer's Disease Neuroimaging Initiative (ADNI).
-
A consent process that addresses the deficits in memory and attention of a patient with AD can improve capacity to give informed consent for early phase AD research.
-
80/100
Epidemiological studies suggest that consumption of DHA is associated with a reduced incidence of Alzheimer disease.
-
We investigated the effects of renin-angiotensin system blockade on cognitive function in patients aged 55 years and older with established atherosclerotic cardiovascular disease or diabetes with end-organ damage in two clinical trials.

(18)F-Flutemetamol performs similarly to the (11)C-PIB parent molecule within the same subjects and provides high test-retest replicability and potentially much wider accessibility for clinical and research use.
-
