Objective: To determine the prevalence of cognitive impairment in the elderly and its relation with sociodemographic and health factors in the Mexican population.
Material And Methods: From the first wave data of the National Aging and Health Study, collected in 2001 in Mexico, subjects 65 years or older and who had completed a cognitive assessment were selected. Subjects were classified according to two groups: with and without cognitive impairment, based on the cutoff point corresponding to the 10th percentile of the total cognitive assessment score, adjusted for age and educational level. All subjects with cognitive impairment that also had difficulty with one of the activities of daily living were classified as a third group: with cognitive impairment and functional dependency. Prevalence rates were calculated, and an association with demographic and health variables was established through regression analysis.
Results: Seven percent of the population had cognitive impairment while 3.3% had both conditions. The probability of cognitive impairment was not significantly associated with any demographic or health variables. Cognitive impairment and functional dependency indicated an association with gender, age, marital status, diabetes, stroke, heart disease and depression.
Conclusions: The high prevalence of cognitive impairment and its relation with chronic disease frequently observed in the Mexican elderly suggest the need to increase early identification of both conditions in the population.

Neural effects of memory training to reduce false memories in older adults: Univariate and multivariate analyses.

The growing population of older adults emphasizes the need to develop interventions that prevent or delay some of the cognitive decline that accompanies aging. In particular, as memory impairment is the foremost cognitive deficit affecting older adults, it is vital to develop interventions that improve memory function. This study addressed the problem of false memories in aging by training older adults to use details of past events during memory retrieval to distinguish targets from related lures.

Individuals with high math anxiety (HMA) demonstrate a tendency to avoid math-related tasks, a behavior that perpetuates a detrimental cycle of limited practice, poor performance, increased anxiety, and further avoidance. This study delves into the cognitive and neural bases of math avoidance behavior in HMA through the lens of reward processing. In Experiment 1, participants reported their satisfaction level in response to the reward provided after solving an arithmetic problem.

Extensive research has demonstrated endurance exercise to be neuroprotective. Whether these neuroprotective benefits are mediated, in part, by hepatic ketone production remains unclear. To investigate the role of hepatic ketone production on brain health during exercise, healthy 6-month-old female rats underwent viral knockdown of the rate-limiting enzyme in the liver that catalyses the first reaction in ketogenesis: 3-hydroxymethylglutaryl-CoA synthase 2 (HMGCS2).

This review aimed at summarizing the literature evidence on clinical, cognitive, and neurobiological correlates of impaired timing abilities in schizophrenia (SCZ). Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic literature search was conducted in PubMed, EMBASE, and PsycInfo by looking at correlates between timing abilities and either symptom severity, cognition, and neurobiological data (imaging and electroencephalography) in individuals with SCZ, without restrictions on study design. A total of 45 articles were selected: associations were identified between impaired timing performance and positive, negative, and disorganization symptoms, as well as with executive functioning, working memory, and attention.

Background: Previous reports suggest patient and caregiver lack of awareness of dementia. Little is known about how this varies by ethnicity and how informal (family) caregiver burden is associated with knowing a dementia diagnosis.
Objective: To investigate whether participants with probable dementia were aware of a diagnosis provided by a physician and how this differed among Mexican American and non-Hispanic White participants; whether having a primary care physician was associated with dementia diagnosis unawareness; and the association of dementia diagnosis unawareness with caregiver burden.
