Dementia

Dementia is not a specific disease. It is a descriptive term for a collection of symptoms that can be caused by a number of disorders that affect the brain. People with dementia have significantly impaired intellectual functioning that interferes with normal activities and relationships.

What Causes Dementia?

Dementia occurs due to loss of brain function that occurs with certain diseases. It can affect several brain functions such as memory, thinking, language, planning, behavior and judgement. Dementias are usually progressive and worsen with time. They usually are degenerative and non reversible.

Early cognitive stimulation preserves memory in Alzheimer’s

A team from the Institute of Neurosciences of the University of Barcelona (UBneuro) has discovered that early and sustained cognitive stimulation can help preserve brain connectivity and memory in Alzheimer's disease, even in advanced stages of the pathology.

FDA-approved anti-seizure drug could help fight Alzheimer's disease

While physicians and scientists have long known Alzheimer's disease involves the buildup of toxic protein fragments in the brain, they have struggled to understand how these harmful fragments are produced.

Lifelong learning associated with lower risk of Alzheimer's disease

Engaging in a variety of intellectually stimulating activities throughout life, such as reading, writing and learning a language, is associated with a lower risk of Alzheimer's disease and slower cognitive decline, according to a new study published on February 11, 2026, in Neurology, the medical journal of the American Academy of Neurology.

Alzheimer’s plaques decline after CAR-T immune cell treatment in preclinical study

Researchers engineered CD4+ chimeric antigen receptor T cells targeting fibrillar amyloid beta and tested them in a mouse Alzheimer model. The preclinical study showed reduced amyloid pathology and altered neuroimmune responses, supporting CAR-T immunotherapy as a potential future Alzheimer strategy.

Dementia Care Aware partners with IHI to advance age-friendly care

Dementia Care Aware (DCA) is collaborating with the Institute for Healthcare Improvement (IHI) to support its March 2026 Action Community, a community learning experience that helps health systems across the country implement the 4Ms Framework of an Age-Friendly Health System.

Study suggests shingles vaccine may help lower Alzheimer’s and dementia risk

A large observational electronic health record study found that older adults receiving the recombinant zoster vaccine showed substantially lower rates of diagnosed dementia compared with matched unvaccinated individuals. The association persisted after multiple sensitivity analyses, although causality remains unproven and longer follow-up is required given the long latency of dementia.

Choroid plexus enlargement in Long COVID signals cognitive risk

The increased size of, and lesser blood supply to, a key brain structure in patients with Long COVID tracks with known blood markers of Alzheimer's disease and greater levels of dementia, a new study finds.

Study links eye movements to real-time memory retrieval

The eyes may reveal how experiences are recalled according to new Baycrest research that suggests that shifts in eye movements play a critical role in memory retrieval.

Low-grade inflammation connects aging, obesity and cognitive impairment

Obesity and older age are strongly associated with low-grade inflammation in the body, a condition that appears closely linked to cognitive decline and dementia.

Study identifies link between gut bacteria and deterioration of the brain in ALS, dementia

A significant discovery by Case Western Reserve University researchers could change how doctors treat two of the most devastating neurodegenerative diseases.

Cognitive speed training shows potential to delay dementia for two decades

Adults age 65 and older who completed five to six weeks of cognitive speed training - in this case, speed of processing training, which helps people quickly find visual information on a computer screen and handle increasingly complex tasks in a shorter time period - and who had follow-up sessions about one to three years later were less likely to be diagnosed with dementia, including Alzheimer's disease, up to two decades later, according to new findings published today in Alzheimer's & Dementia: Translational Research and Clinical Interventions.

Novel neuroprotective drug improves recovery after acute ischemic stroke

Stroke patients treated intravenously with loberamisal, a novel neuroprotective medication, daily for 10 days and starting within 48 hours of stroke symptoms, had better recovery than patients who received a placebo, according to a preliminary late-breaking science presentation at the American Stroke Association's International Stroke Conference 2026.

Dementia collaborative care delivers greater value than Alzheimer’s medication

Programs that match caregivers with patient navigators yield better outcomes than Alzheimer's drug – but combining the two may be best.

Does motherhood influence brain aging? New research suggests a positive cognitive association

Longitudinal data from postmenopausal women suggest that cumulative pregnancy duration and breastfeeding history are associated with modestly better cognitive performance later in life. These associations reflect higher cognitive trajectory levels rather than proven slowing of decline, and causality remains uncertain.

Study elucidates key steps in the ubiquitin tagging of mutated huntingtin protein

Researchers have elucidated key steps in the ubiquitin tagging of the mutated huntingtin protein, providing hope for future therapies.
