Scientists are investigating the effects of stereotype threat on cognitive function, particularly in women and minority groups. The study aims to understand the physiological processes underlying these impairments and develop strategies to help affected groups cope with social stigma.
The studies confirm SEROQUEL's effectiveness across a range of schizophrenia symptoms, including positive and negative symptoms, and cognitive functioning. Cognitive improvements were seen in patients treated with SEROQUEL.
A study of 97 Parkinson's disease patients found that those with elevated homocysteine levels were more depressed, had worse cognitive functioning, but no difference in physical functioning. High homocysteine levels are likely due to the use of levodopa in these patients.
A long-term study found that people with diabetes are at a 65% increased risk of developing Alzheimer's disease compared to those without the condition. The study also showed that cognitive decline in perceptual speed was associated with diabetes, but not other cognitive systems.
Researchers from Rush University Medical Center have discovered that diabetics are at a significantly higher risk of developing Alzheimer's disease. The study, which followed over 800 Catholic nuns and priests for five years, found a 65% increase in the risk of AD among those with diabetes.
Scientists successfully deleted primary afferent neurons expressing vanilloid receptor 1, leading to potential breakthroughs in pain management. The study aims to provide new avenues for treating chronic pain by targeting the TRPV1 receptor.
Researchers found that alcohol impairs cognitive functioning even when motor functioning appears normal. The study suggests that the motor component of information processing recovers during declining blood alcohol concentrations, but the cognitive effects linger, creating a 'illusion' of sobriety.
A study published in The Journal of Cognitive Rehabilitation found that computer-assisted cognitive rehabilitation improved treatment response for individuals with substance abuse. Participants who received the rehabilitation program stayed longer in treatment and had higher graduation rates compared to those who did not receive it.
A recent study published by the American Academy of Neurology found a strong link between smoking and accelerated cognitive decline in elderly individuals. Smoking was shown to lower MMSE scores by up to .16 points per year, with higher cigarette pack-year exposure leading to greater declines.
A JAMA study validates a new class of drugs for treating advanced Alzheimer's, improving cognitive function and daily life. The combination of memantine and donepezil shows statistically significant benefits for patients with moderate to severe Alzheimer's disease.
Researchers found a strong link between increased stroke risk and lower cognitive function in individuals who have never had a stroke or dementia. The study suggests that preventing stroke risk factors may also help prevent cognitive decline.
Researchers found that patients with Parkinson's disease performed better when their stimulators were turned off in tasks requiring spatial memory and inhibitory control. The study suggests that adjusting stimulation levels may be possible to minimize cognitive impairment while maintaining motor benefits.
A study found that repeated alcohol detoxifications are associated with increased impairment of cognitive function, specifically frontal-lobe damage. Patients with two or more previous withdrawals performed worse than those with fewer or no experiences in tasks requiring attention and executive function.
Researchers found that executive cognitive functioning is more impaired during the descending limb of the blood alcohol concentration curve, when people no longer feel stimulated by alcohol. This effect lasts much longer than previously believed, with significant ramifications for behaviors like driving and aggression.
A study found that white college students with high racial bias experienced a decrease in executive function after interacting with black people. Conversely, those who interacted with white people showed no subsequent loss of cognitive function.
A new software package called MiniCog is being developed to evaluate cognitive processes and determine mental readiness for tasks. The program uses a series of nine cognitive tasks to assess attention, working memory, problem-solving ability, and other mental functions.
A large randomized trial found no improvement in cognitive function among postmenopausal women with coronary disease after four years of hormone replacement therapy. The study provides no evidence regarding the effect of estrogen-only therapy on cognition, contradicting some previous studies that showed an improvement in younger women
Chicago researchers awarded $9 million NIH grant to investigate the impact of lifestyle experiences on cognitive function and Alzheimer's disease. The study aims to understand how cognitively stimulating activities can increase neural reserve and reduce the likelihood of memory loss and other clinical signs of Alzheimer's.
A study of Peruvian children found that chronic malnutrition in infancy is associated with poor cognitive function in late childhood. Children who were stunted or had Giardia infections performed lower on the Wechsler intelligence scale, highlighting the importance of addressing nutritional deficiencies and parasitic infections early on.
A study found that dopamine transporter levels improved in methamphetamine abusers after prolonged abstinence, suggesting potential for recovery. However, cognitive and motor function did not show significant improvement, highlighting the need for further research.
A 24-week study found consistent benefits of ARICEPT in patient function, cognition, behavior, and activities of daily living. The medication showed statistically significant overall improvement vs. placebo in behavioral disturbances associated with Alzheimer's disease.
A study found that emotional support was a significant predictor of better cognitive function in older adults, independent of other risk factors. Unmarried participants showed better cognitive function than married ones, suggesting that the presence of a spouse may have negative effects on cognition due to care burdens.
A study found that recently detoxified male alcoholics experience significant cognitive and motor deficits, particularly in gait and balance. These impairments can lead to an increased risk of falls and may be linked to the 'premature aging hypothesis,' where the brains of older alcoholics resemble those of non-drinkers.
Researchers found that chronic sleep deprivation can lead to changes in glucose tolerance and hormone secretion, resembling the effects of advanced age or early stages of diabetes. Sleep deprivation also altered thyroid-stimulating hormone production and cortisol levels, with significant consequences for overall health.
A study of 11 young men found that sleep debt increased glucose concentrations in the blood, while altering cortisol levels and thyroid hormone regulation. The research suggests that persistent sleep debt may exacerbate age-related chronic disorders.
A study found that people potentially at high risk for schizophrenia exhibit executive functioning problems before psychosis onset, which could serve as an early warning sign. This discovery may allow mental health professionals to test for and intervene in executive functioning issues.
A recent study by Yale University School of Medicine researchers found that nearly 30% of people over 72 years old regained their ability to perform essential activities of daily living. The strongest predictor of recovery was age, with participants aged 85 or younger being more likely to regain independent ADL function.
A study found that serotonin function declines with age, particularly in the hippocampus region, leading to impaired cognitive function and increased risk of depression. Researchers hope to develop new therapeutic approaches based on these findings.
Daily performance testing is suitable for immediate determination of relevant psychomotor impairment at the start of work. However, managers must remain aware of test limitations associated with job requirements, such as decision-making skills required for driving a truck safely.
