ReviewA Systematic Review of Metacognitive Differences Between Alzheimer's Disease and Frontotemporal Dementia.
Clinicians often have difficulty distinguishing between various forms of dementia to achieve a correct diagnosis. Little research has been done to examine whether awareness of one's cognitive deficits, or metacognitive monitoring, might differ between dementia diagnoses, thereby providing an additional means of differentiating between dementia subtypes. ⋯ Greater monitoring deficits were apparent in frontotemporal dementia than in Alzheimer's disease, and participants with frontotemporal dementia were less likely to utilize task experience to update and improve the accuracy of subsequent monitoring judgments. Results provide evidence for the utility of metacognitive measures as a means of distinguishing between Alzheimer's disease and frontotemporal dementia.

Review Meta AnalysisMelatonin for sleep disorders and cognition in dementia: a meta-analysis of randomized controlled trials.
The current review aims to examine melatonin therapy for both sleep disturbances and cognitive function in dementia. We searched all randomized controlled trials published in Medline, Embase, the Cochrane Library, China National Knowledge Infrastructure, the Cochrane Dementia and Cognitive Improvement Group’s Specialized Register, and Clinical Trials.gov. The grading of recommendations assessment, development and evaluation framework was used to assess the quality of evidence. ⋯ Conversely, cognitive function did not change significantly. Additionally, there was no report of severe adverse events. Given the current studies, we conclude that melatonin therapy may be effective in improving SE and prolonging TST in patients with dementia; however, there is no evidence that this improvement impacts cognitive function.

ApoE type 4 allele affects cognitive function of aged population in Tianjin City, China.
Apolipoprotein E type 4 allele (ApoE∊4) is known as a risk gene for the late-onset Alzheimer's disease, and the relationship between ApoE∊4 and cognitive function of the elderly people has drawn the attention of the scientists. In this study, we investigated the relationship between ApoE∊4 and the cognitive function of the old people. ⋯ The ApoE∊4 primarily influenced the global cognitive function, perceptual speed, and work memory. The results indicate that ApoE∊4 has significant negative effect on the cognitive function of the elderly people who are 60 years and older.

ReviewMelatonin and melatonin agonist for delirium in the elderly patients.
The objective of this review is to summarize the available data on the use of melatonin and melatonin agonist for the prevention and management of delirium in the elderly patients from randomized controlled trials (RCTs). A systematic search of 5 major databases PubMed, MEDLINE, PsychINFO, Embase, and Cochrane Library was conducted. This search yielded a total of 2 RCTs for melatonin. ⋯ The search for a melatonin agonist for delirium in the elderly patients yielded 1 study of ramelteon. In this study, ramelteon was found to be beneficial in preventing delirium in medically ill individuals when compared to placebo. Ramelteon was well tolerated in this study.

ReviewDiagnosis and prognosis in idiopathic normal pressure hydrocephalus.
Idiopathic normal pressure hydrocephalus (iNPH) is a communicating hydrocephalus, of unknown pathophysiology, characterized by the classical triad of dementia, urinary incontinence, and ataxia. The most popular treatment option is shunt surgery, although it is not a cure. The diagnosis of the disorder is challenging as it may mimic a lot of other neurological conditions and has no distinct biomarker. ⋯ The predictors deciding the postsurgical prognosis has been discussed. Improved shunting modalities and novel shunt materials with valve adjustments have improved the precision of the shunting procedures. Still we have lot more to achieve in terms of early diagnosis and definitive management of iNPH.
