Can your identity be preserved amid dementia?

How do 'dementia villages' work?

The goal of good dementia care is to preserve a patient's quality of life as the incurable disease progresses, maximizing their ability to lead normal lives and maintain their health and dignity. Dementia villages are small neighborhoods built for people with severe dementia, with typical neighborhood haunts like salons or grocery stores staffed by people trained in dementia care, helping residents maintain a sense of autonomy and connection.

After a dementia diagnosis, it's important to plan ahead but also savor the moment

The next steps after a diagnosis include taking lifestyle steps to slow disease progression and completing legal paperwork about long-term medical preferences. It's also important to appreciate the moments and days ahead and find humor in them, when possible. (Some users may encounter a paywall.)

How neurodegeneration happens, the underlying disease process of dementia

Dementia symptoms may vary between individuals, and may include mood changes, difficulty walking, speaking, and memory problems. It can progress over many years, occurring due to progressive damage to nerve cells in the brain. This degradation may happen for myriad reasons, and its triggers are under investigation.

Dementia describes progressive memory issues that impact daily activities

Although Alzheimer's disease is sometimes thought of synonymously with dementia, there are multiple types of dementia, which manifest in memory loss and other symptoms that make it challenging to perform daily tasks. These types include Lewy Body dementia, vascular dementia, and frontotemporal dementia. Parkinson's disease is not a form of dementia, but this movement disorder can sometimes develop into issues with memory and a formal diagnosis of dementia.

How frontotemporal dementia changes your personality

Significant changes in personality later in life are often attributed to psychological factors. But Dr. Bruce Miller, long-time researcher of FTD, argues this shift is most often attributable to changes in the brain.

Learn the differences between mild cognitive impairment and age-associated memory loss

Mild cognitive impairment is a condition in which people experience more thinking and memory problems than expected for their age. It's often associated with depression and anxiety. Daily routines, writing things down, and healthy lifestyle choices can help cope with the condition, but there's no cure. The condition elevates the risk of developing dementia and Alzheimer's.

How reading and writing can lower dementia risk by almost 40%

Research published in 2026 that tracked almost 2,000 older adults for an average of nearly eight years suggests that lifelong exposure to intellectual stimulation, such as learning a language, reading, and writing, can lower dementia risk by as much as 40%.

Memory disorders disrupt the brain's ability to make, store, or recall memories

These disorders stem from reversible issues like vitamin deficiencies or irreversible causes such as stroke or dementia. Only one type of dementia—familial Alzheimer’s disease—is directly inherited and accounts for about 20% of Alzheimer’s cases.

How Alzheimer's caregivers get pulled into their loved one's reality

Caregivers, most often children and spouses, do not just witness a family member's cognitive decline—they also often become drawn into it, navigating a world in which the typical rules of time, order, or logical continuity may not apply.

Super-agers: seniors 80 and above with the memory ability of people in their 50s

Studies show the number one indicator of whether someone is a "super-ager" is not diet or genetics, but the extent of their social relationships. Moreover, scans reveal noticeable physical differences in certain parts of the brain in patients with extensive social networks.

Some dementia cases may be linked to microorganisms in the brain

Researchers now know that, much like the gut, the brain is home to an ecosystem of microorganisms—the brain microbiome. While this area of study is still new, some scientists believe 50% of bacteria-caused dementia cases could be treated. (Some users may encounter a paywall.)

Does our fear of Alzheimer's create stigma around its treatment?

Surveys suggest our fear of Alzheimer's as a disease outranks that of heart disease and cancer. This piece argues our fear of aging and the slipping away of our mental capacities make it more difficult to treat Alzheimer's compassionately.

America's financial burden from dementia in 2025 was $781 billion

That figure, calculated by researchers at the University of Southern California, includes medical and long-term care costs, unpaid family and friend caretaking, lost productivity for patients and their families, and the economic loss in quality of life for patients and their families. In 2025, they estimate there were 5.6 million people living with dementia.

An online presence provides a means of grieving and honoring individuals after death

Shifting perspectives toward the increasing importance of digital profiles of the dead have made anticipatory management of one's digital legacy more critical. Experts suggest choosing a tech-savvy relative—such as a cousin—over a spouse to reduce confusion about what to preserve or discard, as well as how to access password-protected content.

Why 'spacing out' or dissociating may help reduce trauma awareness

Dissociation may have developed as a defense mechanism in the brain to help navigate intense emotional or physical situations by providing out-of-body experiences that put distance between the mind and the environment. However, in about 1.1% and 1.5% percent of the general population, a severe form of this separation can produce alternate identities, or alters.

Alzheimer's can lead to brain shrinkage, with an average of around 2% of volume reduction per year

Always forget a face? The science of face-blindness

Faces and names don't always go together in some people's minds. While everyone forgets other peoples's names occasion, people diagnosed with prosopagnosia can't recognize faces, much less names. Even friends can family members can appear to be strangers. This article covers the diagnosis and issues attendant to prosopagnosia and its sufferers.

Smell is a robust memory cue for individuals with Alzheimer's disease

Odor is more effective than both visual and verbal cues for triggering autobiographical recall in Alzheimer's disease, according to 2021 research.

Core memories are a popularized version of autobiographical memories

Core memories are not limited to five key events, do not individually shape personality traits, and are not formed in childhood. Our strongest memories are formed in early adulthood, but are as prone to error as any other memory.

The brain consolidates memories during sleep

During sleep, the brain appears to process memories from the day and encode them into long-term storage. At the same time, the brain prunes old memories out of the brain that are no longer useful. Understanding this process also sheds light a various neurodegenerative diseases.

An essay exploring how living day-to-day with a brain implant helps restore a sense of identity

Companies like Neuralink are experimenting with volunteers who have lost control over their bodies. Many of the program's participants claim the most significant benefit from the tool is the ability to perform simple, mundane tasks, such as playing video games or shaking hands, rather than more obvious milestones like walking or eating. This essay explores what it's like, day to day, to use a brain implant.

Four in 10 CPR patients report consciousness not captured by standard measures

A recent study found people revived by CPR after cardiac arrest reported they experienced some amount of consciousness during clinical death, suggesting our brains are capable of thought and memory for significantly longer after death than previously thought.

The ideas of Einstein and Freud combined in 'The Persistence of Memory'

The Persistence of Memory was painted on a canvas roughly the size of a sheet of paper, depicting a desolate landscape with melting clocks, ants, and a distorted figure. The piece incorporates Freud and Einstein's ideas, resulting in a haunting composition symbolizing time's fluidity and Dalí's personal anxieties.

Prolonged Grief Disorder has certain recognizable risk factors

This official diagnosis is characterized by intense, daily symptoms of grief a year after the loss of a loved one among adults and faster—around at least six months—for kids and teens. Factors that put people at increased risk of this disorder include being single, attachment anxiety, violent or unnatural death, low education, low income, and multiple losses, among others.

Nostalgia is a psychological coping mechanism that can help combat loneliness—but it's created from bias

Researchers have observed that though nostalgia can help counteract feelings of loneliness, our memories of the past are somewhat rose colored. Negative emotions seem to fade faster than positive ones, a phenomenon that they suggest may be a psychological coping mechanism so that memories don't hurt every time they're recalled.
