dementi

Dementia, or dementi in some languages, is a syndrome characterized by a persistent decline in cognitive function beyond what might be expected from normal aging. It typically involves memory impairment plus at least one other cognitive domain (such as language, attention, executive function, or visuospatial skills) and is sufficient to interfere with daily activities and independence. The condition is usually progressive and most forms are not curable, though some causes are treatable if identified early.

Common symptoms include memory loss, difficulties with language and communication, problems with planning or organizing, reduced ability to concentrate, and changes in mood or behavior. People may have trouble with familiar tasks, navigation, or recognizing people. Symptoms tend to worsen over time, affecting daily life, independence, and the ability to live at home without support.

Dementia has multiple causes and is one of several brain disorders. Alzheimer’s disease is the most common form, but vascular dementia, Lewy body dementia, frontotemporal dementia, and mixed dementias are also seen. Risk factors include increasing age, family history, and certain genetic factors. Modifiable risk factors include cardiovascular health, diabetes, hypertension, smoking, and physical inactivity.

Diagnosis involves a clinical assessment of history and symptoms, cognitive testing, and brain imaging to rule out other conditions. Blood tests and other investigations may be used to identify reversible causes or biomarkers.

Management focuses on symptom relief, safety, and planning for the future. While there is no cure, treatments such as cholinesterase inhibitors and memantine may help some symptoms. Non-pharmacological approaches—physical activity, cognitive stimulation, social engagement, sleep management, and caregiver support—are important. Ongoing medical care and social services support patients and families as the disease progresses.
