Better management of cardiovascular risk factors and higher levels of education may have contributed to this improvement.
Someone whose hippocampus stayed the same size was nearly 6 times more likely to develop Lewy body dementia.
In 2016, an estimated 5.4 million US adults have Alzheimer disease.
Sundowning is a complex multifactorial condition that has eluded rigorous understanding of its pathophysiological causes.
Basic Research Findings for the Practicing Clinician
Those with lower BMI showed higher levels of beta-amyloid, closely tied to the onset of Alzheimer's disease.
The findings suggest that interactions between beta-amyloid and tau lead to neurodegeneration in Alzheimer's.
Cases of all-cause dementia and Alzheimer's did not significantly differ between study groups, but vascular care is safe and may reduce incidence of non-Alzheimer's dementia.
The effects of aggregate genetic AD risk are detectable before symptoms appear, even early in life.
Distinguishing between psychiatric disorders and AD is crucial because of the differing prognosis and management of the two.
If transmission of neurodegenerative diseases such as dementia of any type, AD, or PD does occur, it is rare.
Tetrahydrocannabinol (THC) is the main active chemical ingredient found in cannabis and is a potent cannabinoid receptor (CB)-1 agonist.
Modifiable risk factors (eg, smoking, hypertension, sedentary behavior, overweight/obesity, and social engagement) contribute to nearly half of documented dementia cases.
Cognitive test scores are negatively correlated with blood-brain barrier disruption in patients with early AD.
Although inconclusive, late-onset Alzheimer's Disease could be triggered by infectious pathogens.
Researchers identified increased fibrinogen levels and amyloid-β deposits in the blood vessels and brain parenchyma of patients with Alzheimer's disease.
The case suggests that some patients with HIV and dementia may be misdiagnosed with HIV-associated brain disorders.
Administration time for cognitive assessment screenings is currently suboptimal in many clinical settings.
Researchers identified 8 categories of sensory stimulation interventions that significantly influenced dementia.
White matter hyperintensity volume differences were seen 6 years before Alzheimer's symptoms.
Researchers found an elevated risk of dementia after adjustment for age, sex, and comorbidities.
Declines in processing sleep and episodic memory were observed in those with low levels of activity.
While scientists have long known that tau is involved in dementia, the way in which it hinders cognitive function has remained uncertain.
There was improvement in cognitive performance and brain function in those who took the blueberry powder.
Higher educational level and increased cognitive activity has been associated with less amyloid deposition in APOE4 carriers.
While many studies have explored the role of microglia in Alzheimer's, very few researchers have examined the role of the adaptive immune system.
There is substantial evidence that mental stimulation in middle age helps to delay the onset of memory and thinking problems.
The findings suggest that it may be possible to develop a non-invasive tool for early diagnosis of Alzheimer's disease.
Those who had 2 to 3 alcoholic drinks a day had a 77% lower risk of dying during the study period than those who had 1 or fewer drinks a day.
Participants' cardiorespiratory fitness improved by about 8%, and the greater the fitness improvements, the more growth in the cortical layer.
