The increasing elderly population will pose significant challenges in cancer care, including inadequate training of healthcare professionals and inappropriate ageist attitudes. Improved technology may help address some issues, but a digital divide and escalating costs threaten the accessibility of cancer treatment.
Decreased inhibitory ability in late adulthood can lead to prejudice, social inappropriateness, depression, and gambling problems. Poor inhibition also predicts increased rumination, leading to depression. Scheduling social activities earlier in the day may help mitigate these issues.

The Hypertension in the Very Elderly Trial (HYVET) found that lowering blood pressure significantly reduces both stroke and mortality in patients aged 80 and over. The trial, which began in 2001, involved 3,845 patients from across the world and stopped early due to significant reductions in overall mortality.
Elizabeth Stine-Morrow's "Dumbledore hypothesis" suggests that aging adults can compensate for age-related cognitive changes by allocating effort differently. Older readers with good comprehension spend more time building a 'situation model' and pausing to integrate new information.
Older adults experience cognitive decline that affects their ability to comprehend humor, according to Washington University researchers. However, this decline does not mean they cannot understand humor, and previous experiences, preferences, and personality play a significant role in humor comprehension.
A new study found that hip and knee replacements are rarely performed in patients over 100 due to concerns about short-term life expectancy. However, the research suggests that these procedures should not be denied solely based on age and that the benefits may outweigh the risks.

A new study found that even slightly abnormal pre-operative red blood cell counts can increase the risk of death or cardiac events after major non-cardiac surgery. Researchers analyzed data from 310,311 veterans and found that maintaining a normal red blood cell count may be beneficial for elderly patients facing surgery.
A new study found that both newer atypical and older conventional antipsychotics are associated with increased mortality in older adults with dementia. The risk appears to be highest for conventional antipsychotics.

After six months of twice-weekly resistance training, older adults' mitochondrial function and muscle strength improved significantly, with some even surpassing those of younger adults.
Researchers found that older adults with a history of excess weight in midlife or earlier had worse physical performance than those who were normal weight throughout adulthood. Maintaining healthy weight may prevent or delay physical disability as we age.
Research suggests that older-adult dieting won't lead to reduced physical function, with women losing muscle but maintaining aerobic fitness and strength. Weight regain also doesn't negatively impact physical performance, as long as the regained weight is not excessive fat.
A University of Alberta study found that seniors are being stereotyped as grouchy and inflexible, with caregivers holding misconceptions about aging and Alzheimer's disease, while most seniors are adaptable and seldom angry. The study highlights the need for more education about aging and dementia to promote positive care.

Research shows that elderly patients (90+ years) who receive recommended treatments for acute coronary syndromes have better survival rates, but at a higher risk of bleeding complications. Guidelines must be balanced to balance survival benefits with increased bleeding risk.
A study of 4,681 older adults found that those with high levels of depressive symptoms were more likely to develop type 2 diabetes over a 10-year period. The researchers followed participants for 10 years, tracking changes in depressive symptom scores and the development of diabetes.
A recent editorial by Dr. Malaz Boustani suggests that primary care physicians should not assess the safety of older drivers due to resource constraints and potential conflicts of interest. The editorial is based on a survey of Canadian family physicians, who reported low confidence in assessing driving fitness.
Researchers at MIT have developed a humanoid robot called Domo that can adapt to new environments, grasp objects, and interact with humans. The robot learns from its experiences and can perform tasks like putting away dishes, which could help elderly or wheelchair-bound people.

A University of Alberta study reveals that older adults feel less confident about their computer knowledge due to memory issues and health problems. The research highlights the importance of adapting computer technology to accommodate vision, hearing, and motor skills impairments.
A study found that undocumented immigrants with pregnant women account for 48,391 Emergency Medicaid cases, with 99% being Hispanic and 95% female. This trend indicates an increasing burden on publicly funded healthcare, necessitating improved services such as comprehensive contraceptive care and chronic disease management.
As people age, their neurons must speak more loudly to muscles to achieve precise control, leading to poorer physical responses and increased falls. Exercise, such as weight training, can increase firing rates and preserve motor capacity in older adults.
A University of Virginia study suggests that older adults are more likely to commit suggestibility errors, where they believe an event occurred when it was suggested, and have high confidence in their recollections even if wrong. This has significant implications for the reliability of older persons' eyewitness testimonies in courtrooms.
New research found that older adults gain fat and lose lean mass each year until age 80, contributing to disability. The study also revealed that those born later experienced higher body fat percentages, highlighting the impact of the obesity epidemic on aging
