Impaired awareness of memory deficits has been recognized as a common phenomenon in Alzheimer's disease (AD) and research is now increasingly focusing on awareness in groups at risk for future dementia. This study aimed to determine whether levels of awareness differ among healthy elderly people and patients with subjective cognitive decline (SCD), amnestic and non-amnestic subtypes of mild cognitive impairment (aMCI, naMCI), Alzheimer's disease (AD) and Parkinson's disease (PD), to explore correlates of awareness and to establish frequencies of memory over- and underestimation within each diagnostic group.

756 consecutive outpatients of a memory clinic and 211 healthy controls underwent thorough neuropsychological testing. Impairment of awareness was measured as the difference between subjective memory appraisals (16-item questionnaire on current memory-related problems in everyday life) and objective memory performance (15-item delayed recall task). Subgroups of over- and underestimators were classified using percentile ranks of controls.

At group level, awareness significantly decreased along the naMCI→aMCI→AD continuum, with naMCI patients showing a tendency towards overestimation of memory dysfunction. PD patients showed accurate self-appraisals as long as memory function was largely unaffected. However, there was a considerable between-group overlap in awareness scores. Furthermore, different correlates of awareness were observed depending on the diagnostic group. In general, unawareness seems to be associated with decreased cognitive performance in various domains (especially memory), higher age and lower levels of depression and self-reported functional impairment.

Impaired awareness is an important symptom in aMCI. Yet, given the considerable variability in awareness scores, longitudinal studies are required to evaluate their predictive power.

Considering people with dementia, increasing cognitive, physical, and environmental impairments can impede the capacity to express and experience intimacy and sexuality. When a move to a residential (nursing) home becomes inevitable, increasing dependency can influence this even more. The aim of the review is to provide a structured overview of all elements of intimacy across the full spectrum of intimacy and sexuality in people with dementia, living in specialist residential care.

A systematic search and review were conducted. Research published between 1990 and 2013 was identified in the electronic databases: Pubmed, PsychInfo, and Medline. Inclusion and exclusion criteria were predefined. Selected studies were assessed on quality, using the Mixed Methods Appraisal Tool.

Twelve of the 215 initially retrieved unique research publications were selected. A varied range of studies were found; these studies differed in design, research quality, searched population, and research theme. Different themes emerged: intimate and sexual behavior, knowledge and attitudes, capacity to consent and care culture, and staff training and guidelines.

Although results were found in a wide range of intimate and sexual behavior, knowledge, attitudes and needs of others, and descriptions of culture in residential and nursing homes, the perspective of residents was lacking in literature. Also a “protective” care paradigm was found throughout. Future research is needed to highlight resident perspective and develop training opportunities and guidelines for care staff.

Neuropsychiatric symptoms (NPS) often occur in patients with dementia. Understanding the course of NPS in dementia is important for healthcare professionals for psycho-educational purposes and adequate and timely interventions to prevent or diminish NPS as much as possible.

We conducted a systematic literature search in several electronic databases. We combined search strings for the terms dementia, community-dwelling, cohort studies and NPS. Screening titles and abstracts, assessing the methodological quality and data-extraction were independently conducted by at least two authors.

This literature search revealed 6605 unique records of which 23 studies were included in data synthesis. In total 7184 patients participated in the included studies with a mean number of 312. Sixty percent of the participants were female and the mean age of all participants was 74.8 years. Follow-up varied between 1 and 6 years; in 17 studies loss to follow-up was less than 20% per year. NPS are highly prevalent, incident and persistent although frequency parameters vary considerably across studies. Delusions/delusional misidentification, wandering/agitation, aberrant motor behavior/motor hyperactivity and apathy are the most common NPS. For hallucinations, delusions/delusional misidentification, paranoia, aggression, wandering/agitation, aberrant motor behavior/motor hyperactivity, disinhibition, apathy, and sleep disturbance increasing trends in point prevalence rates have been found.

NPS in community-dwelling patients are frequent and persistent. The increasing trends of several NPS in the course of dementia require a preventive approach of professional caretakers. For such an approach, a timely diagnosis and adequate professional support to prevent or diminish these problems is necessary.

We aimed to examine trends in the use of psychotropic medications among elderly outpatients with dementia in Japan between 2002 and 2010.

We used data from the 2002–2010 Survey of Medical Care Activities in Public Health Insurance (SMCA-PHI), a nationally representative cross-sectional survey of claims data for the month of June in every year. We included ambulatory care visits by patients aged 65 years or older who were prescribed cholinesterase inhibitors (n = 15,591), and identified use of any psychotropic medications during the survey month.

In 2008–2010, the most prevalently prescribed psychotropic medications to patients with dementia were sedatives-hypnotics (37.5%), antipsychotics (24.9%), antidepressants (13.0%), and mood-stabilizers (2.9%). Between 2002–2004 and 2008–2010, use of second-generation antipsychotics (SGAs) increased from 5.0% to 12.0%, while use of first-generation antipsychotics (FGAs) decreased from 20.6% to 12.9%. These numbers resulted in a 1.1-fold increase in the adjusted prevalence of the overall use of antipsychotics. Quetiapine and risperidone use showed a 4.8- and 1.8-fold increase, respectively, while haloperidol use showed a 2.3-fold decrease.

Despite safety warnings against the use of antipsychotics for patients with dementia in several countries, our study revealed a slight increase in the extensive use of off-label antipsychotics over time in Japan. This finding indicates an urgent need for evaluation of the efficacy of antipsychotics for the approved treatment of severe agitation, aggression, and psychosis associated with dementia. Moreover, psychosocial interventions and antipsychotic withdrawal strategies are needed in order to reduce the overall prevalence of antipsychotic use.

There is a lack of information regarding geographical differences in the incidence and prevalence of dementia diagnosis according to the degree of aging of the population. The objectives of this study were to analyze the rate of dementia diagnoses, and to compare the dementia subtypes and the clinical characteristics of the patients depending on the degree of aging of their municipalities.

We used data from the Registry of Dementias of Girona (ReDeGi), containing the cases of dementia diagnosed in the memory clinics of the Health Region of Girona, in Catalonia (Spain), during 2007–2012. The municipalities were classified by a cluster analysis as aged or young municipalities according to their proportion of older people using population ageing indicators. The incidence rates of dementia diagnosis in each type of municipality were compared.

The ReDeGi registered 4,314 cases in the municipalities under surveillance. The clinical incidence of dementia was lower in aged municipalities (4.5 vs. 6.1 cases per 1,000 person-years aged 65 and over). Patients from young municipalities had an increased frequency of behavioral and psychological symptoms of dementia.

The environment may influence the clinical manifestations of dementia that predispose people to visit health specialists and obtain a diagnosis.

We investigated the characteristics of Alzheimer's disease (AD) biomarkers for mild cognitive impairment (MCI) reversion to cognitively normal (CN).

Of a total of 1,233 participants from the ADNI database, 42 participants with MCI reversion to CN (MCIr), 778 with MCI, and 413 CN were obtained. We evaluated demographics, clinical outcomes, medication use, MCI type, and AD biomarkers, including genetic, cerebrospinal fluid, imaging, and neuropsychological data.

This study showed that the differences between MCIr and CN were only age, Mini-Mental State Examination, and Clinical Dementia Rating – Sum of Boxes, but the differences between MCIr and MCI were not only clinical outcomes but also AD biomarkers, including genetic, cerebrospinal fluid, imaging, and neuropsychological data. Overall, MCIr may be similar to CN and not MCI in clinical characteristics.

With assessment of MCI reversion to CN, the possibility of false-positive errors should be considered. With the assistance of AD biomarkers, MCI can be evaluated more accurately than the conventional criteria.

We examined the associations between serum cholesterol measures, statin use, and cognitive function measured in childhood and in old age. The possibility that lifelong (trait) cognitive ability accounts for any cross-sectional associations between cholesterol and cognitive performance in older age, seen in observational studies, has not been tested to date.

Participants were 1,043 men and women from the Lothian Birth Cohort 1936 Study, most of whom had participated in a nationwide IQ-type test in childhood (Scottish Mental Survey of 1947), and were followed up at about age 70 years. Serum cholesterol measures included total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides, and cholesterol:HDL cholesterol ratio. Cognitive outcome measures were age 70 IQ (using the same test as at age 11 years), general cognitive ability (g), processing speed, memory, and verbal ability.

Higher TC, higher HDL-C, and lower triglycerides were associated with higher age 70 cognitive scores in most cognitive domains. These relationships were no longer significant after covarying for childhood IQ, with the exception a markedly attenuated association between TC and processing speed, and triglycerides and age 70 IQ. In the fully adjusted model, all conventionally significant (p < 0.05) effects were removed. Childhood IQ predicted statin use in old age. Statin users had lower g, processing speed, and verbal ability scores at age 70 years after covarying for childhood IQ, but significance was lost after adjusting for TC levels.

These results suggest that serum cholesterol and cognitive function are associated in older age via the lifelong stable trait of intelligence. Potential mechanisms, including lifestyle factors, are discussed.

The study's aim was to examine the association of alcohol consumption with verbal and visuospatial memory impairment in older people.

Participants were 1,572, aged ≥60 years, in the hospital-based registry of the Clinical Research Center for Dementia of South Korea (CREDOS). Moderate drinking was defined as no more than seven drinks per week and three drinks per day. Memory impairment was defined as performance with more than 1 standard deviation below the mean value on the Seoul Verbal Learning Test and Rey Complex Figure Test.

Those who consumed alcohol moderately, compared with abstainers, had a lower odds of verbal memory impairment (Odds Ratio [OR] = 0.64; 95% Confidence Interval [CI]: 0.46–0.87), adjusting for covariates. Visuospatial memory, however, was not significantly associated with alcohol consumption.

Moderate alcohol drinking is associated with a reduced likelihood of verbal memory impairment among older people attending memory clinics.

The highest increase in the prevalence of dementia in the elderly population is expected in South Korea than in any other country in the world. However, there is no assessment of the community-based general populations’ understanding of dementia in South Korea, in spite of the increasing burden of dementia. Thus, this study assessed the public knowledge about dementia.

This is a population-based, cross-sectional study of 2,189 participants, aged 10 years or older, and living in Seoul, South Korea. A 12-item questionnaire with true/false responses was used to assess the knowledge about dementia from June to November 2011. The data obtained were analyzed using quantitative methods.

The mean score for the knowledge about dementia was 9.0 ± 2.1 points out of 12 points. More than half of the respondents (52.7%) reported that dementia is not treatable, and one-third of the participants did not know that Alzheimer's disease is the most common cause of dementia. The level of dementia knowledge was negatively associated with increasing age, and positively associated with higher education level.

Our results suggest that although laypersons had a fair knowledge about dementia, further educational programs and campaigns are needed to improve knowledge about dementia, more focusing on elderly adults as the target audience and emphasizing the causes and treatments of dementia as educational contents.

Music can be therapeutic to people with dementia; however, little is known about its effect on the family carers. This project aimed to (1) assess the effects of MP3 player use by a person with dementia on caregivers’ mental health and wellbeing, including their self-care and health-promoting behavior and (2) determine whether MP3 player use increases caregivers’ self-reported capacity to cope with their role.

A pre–post quantitative and qualitative design was used. Carers completed a survey prior to commencing and four weeks after using the player. The survey included validated measures to assess the level of stress and coping among carers. Carers also kept a diary of the way they used the MP3 player. Half of the carers were interviewed about their experiences at the end of the study.

Of 59 people who started using the MP3 player, 51 carers completed the four-week study period and surveys. Use of the MP3 player significantly decreased psychological distress, significantly improved the mental health and wellbeing of carers, significantly increased caregiver self-efficacy to manage symptoms of dementia, and was reported to provide valued respite from the high level of vigilance required for caring for a person with dementia.

An MP3 player loaded with music can be a low cost and relatively simple and effective additional strategy to support families caring for people with dementia in the community.

This study identified possible risk factors for newly diagnosed mood disorders, including depressive and bipolar disorders, in prostate cancer patients.

From 2000 to 2006, two cohorts were evaluated on the occurrence of mood disorder diagnosis and treatment. For the first cohort, data of patients diagnosed with prostate cancer was obtained from the Taiwan National Health Insurance (NHI) Research Database. As the second cohort, a cancer-free comparison group was matched for age, comorbidities, geographic region, and socioeconomic status.

Final analyses involved 12,872 men with prostate cancer and 12,872 matched patients. Increased incidence of both depressive (IRR 1.52, 95% CI 1.30–1.79, P <0.001) and bipolar disorder (IRR 1.84, 95% CI 1.25–2.74, P = 0.001) was observed among patients diagnosed with prostate cancer. Multivariate matched regression models show that cerebrovascular disease (CVD) and radiotherapy treatment could be independent risk factors for developing subsequent depressive and bipolar disorders.

We observed that the risk of developing newly diagnosed depressive and bipolar disorders is higher among Taiwanese prostate cancer patients. Clinicians should be aware of the possibility of increased depressive and bipolar disorders among prostate cancer patients in Taiwan. A prospective study is necessary to confirm these findings.

High suicide rates in late middle-aged and older adults are significant public health problems. Although suicide risk and protective factors are well established, more research is needed about suicide planners and attempters. Using multi-year, national epidemiologic survey data, this study identified correlates of making suicide plans and nonfatal suicide attempts among U.S. adults aged 50+ years.

Data are from the 2008 to 2012 U.S. National Survey on Drug Use and Health (NSDUH). Descriptive statistics were used to examine sample characteristics by past-year serious suicidal thoughts, suicide plans, and suicide attempts. Binary logistic regression analyses were used to examine potential correlates (sociodemographic factors, health status, religiosity, psychiatric and substance use disorders (SUDs), and mental health and substance abuse treatment use) of suicide plans and suicide attempts among those who reported serious suicidal thoughts.

Of the 2.5% of the study population that had serious suicidal thoughts (n = 804), 28% made suicide plans and 11.5% attempted suicide. Although 42% of those with serious suicidal thoughts had major depressive episode (MDE), MDE was not significantly associated with suicide plans or attempts in multivariate models. Being employed decreased the odds of making suicide plans, while mental health service use was associated with increased odds of suicide plans. SUDs increased the odds of suicide attempts.

It is important to screen middle-aged and older adults for severe mental and SUDs and suicidal thoughts and to target interventions for likely planners and attempters.

While it is well known that posttraumatic stress disorder (PTSD) is characterized by heterogeneous symptom clusters, little is known about predominant typologies of PTSD symptoms in older adults.

Latent profile analyses (LPAs) were employed to evaluate predominant typologies of PTSD symptoms in a sample of 164 treatment-seeking older adults with childhood war-related trauma. Multinomial logistic regressions were conducted to evaluate predictors of class membership.

LPAs revealed that a 3-class solution best fit the data. These included an Intermediate Disturbance class (50.0%) and two Pervasive Disturbance classes, which differed with respect to severity of avoidance symptoms (Pervasive Disturbance-Low Avoidance: 33.5%, Pervasive Disturbance-High Avoidance: 16.5%). A greater number of traumatic events predicted membership in the Pervasive Disturbance classes. The Pervasive Disturbance-Low Avoidance class had a higher level of education than the Pervasive Disturbance-High Avoidance class. Compared to the Intermediate Disturbance class, the Pervasive Disturbance classes had the highest levels of depression, anxiety and somatization symptoms.

These results suggest that PTSD in treatment-seeking older adults may be characterized by three predominant typologies, which are differentiated by overall severity and avoidance symptoms, lifetime trauma burden, education level, and comorbid depression, anxiety, and somatization symptoms. These results underscore the importance of considering heterogeneity in the phenotypic presentation of PTSD in assessment and treatment approaches for this disorder in older adults.

Several studies have suggested that cognitive training is a potentially effective way to improve cognition and postpone cognitive decline in older adults with mild cognitive impairment (MCI). The MEMO+ study is a randomized, controlled, single-blind trial designed to test the efficacy, specificity, and long-term effect of a cognitive training intervention and a psychosocial intervention in persons with MCI.

One hundred and sixty-two participants with MCI will be recruited. They will be randomized into three groups: cognitive training, psychosocial intervention, and no-contact. Each intervention will last for eight weeks (one session per week) and a booster training session will be provided three months after the end of the intervention. Various proximal and distal outcomes will be measured at pre-intervention as well as at one week, three months, and six months post-training. Proximal outcomes include memory and psychological health measures. Distal outcomes focus on self-rated functioning in complex daily activities and strategies used in daily life to enhance function. Socio-demographic factors (age, gender, and education), general cognition, personality traits, engagement in activities, and self-efficacy will be used as moderators. Enrolment began in April 2012 and will be completed by December 2014.

This study is likely to have a significant impact on the well-being of persons with MCI by contributing to the development of adapted and scientifically supported cognitive and psychosocial interventions.
