Dementera

Dementera is a medical term used to describe a syndrome of chronic, progressive cognitive decline that interferes with daily life. It is caused by brain disease or injury and is not considered a normal part of aging. Dementera encompasses a range of conditions in which memory, thinking, language, and problem-solving abilities are impaired beyond expected levels for age and education.

Causes and risk factors include neurodegenerative diseases such as Alzheimer's disease, vascular dementia, Lewy body dementia, and frontotemporal dementia. Mixed etiologies, brain injuries, infections, and treatable conditions like thyroid disorders, vitamin deficiencies, depression, and certain medications can also contribute. Age is the primary non-modifiable risk factor, while cardiovascular health, education, and genetics influence risk.

Common symptoms involve memory loss that disrupts daily tasks, difficulties with language and communication, impaired planning and judgment, disorientation, changes in mood or behavior, and a decline in the ability to manage personal care. Symptoms typically worsen over time and vary by underlying cause.

Diagnosis relies on clinical assessment, cognitive testing (such as screening and more detailed neuropsychological tests), and medical history. Imaging studies (MRI or CT scans) help identify brain changes and rule out other conditions. Laboratory tests may be used to exclude reversible causes. In some cases, a diagnosis is refined as the disease progresses.

There is no cure for most dementeras, but treatments can slow progression and alleviate symptoms. Medications such as cholinesterase inhibitors and memantine may help some individuals. Nonpharmacological strategies, including cognitive stimulation, physical activity, social engagement, and caregiver support, are important. Management focuses on safety, planning, and addressing comorbidities.

Epidemiologically, dementera prevalence rises with age and places a growing burden on families and health systems worldwide. Ongoing research aims to improve early detection, disease-modifying therapies, and quality of life for patients and caregivers.
