Experts say lack of privacy, safety fears and ageism deny elderly care home residents the right to consensual sex. Formal policies are needed to address this, despite research showing residents want their sexual expression acknowledged.
A recent study found that almost 90% of older adults aged 65-96 were willing to undergo dementia screening, with refusal rates higher among those between 70-79 years old. The study's results suggest that age is the primary factor affecting willingness, with no significant impact from sex, race, or income level.

A new study published in Archives of Internal Medicine reports that gastric feeding tubes may not prevent but rather increase the risk of pressure ulcers in people with advanced dementia. The analysis of thousands of nursing home patients found that those with a feeding tube were 2.27 times more likely to develop a stage II ulcer, and ...
A new study from the Regenstrief Institute and Indiana University has found that individuals with dementia are more likely to die at home rather than in a nursing home. The majority of care for those with dementia is provided in the community by families, contradicting previous assumptions.
Research suggests that lifelong depression increases the risk of developing vascular dementia, while late-life depression may be an early symptom of Alzheimer's disease. A study of over 13,000 participants found a significant association between depressive symptoms in midlife and late life with increased risk of dementia.
