Dementia
Moderate
Dementia is a group of disorders characterized by a decline in memory, thinking, language, problem-solving, or other mental abilities severe enough to interfere with everyday life. It is not a normal part of aging. Different forms of dementia affect the brain in different ways and can produce changes in behavior, movement, communication, and the ability to perform familiar activities. Symptoms and progression vary according to the underlying condition.

When to Seek Medical Attention
Dementia usually progresses gradually, so a sudden change in confusion, alertness, behavior, or physical function should receive urgent medical assessment. Seek emergency care for severe breathing difficulty, seizures, significant injury after a fall, loss of consciousness, or other sudden serious symptoms.

Causes
Dementia can result from several different diseases and brain disorders. Common forms include Alzheimer disease, vascular dementia, Lewy body dementia, and frontotemporal disorders. Alzheimer disease is associated with abnormal protein deposits and loss of nerve-cell connections, while vascular dementia is related to problems affecting blood supply to the brain. Other neurological disorders, brain injuries, infections, metabolic conditions, and certain medications or substances can also cause dementia-like symptoms.
Risk Factors
Increasing age is the strongest known risk factor for dementia, although dementia is not an inevitable consequence of aging. Other factors associated with increased risk include a family history of dementia, smoking, uncontrolled diabetes, high blood pressure, excessive alcohol use, cardiovascular disease, and certain neurological conditions. Risk varies according to the type of dementia, and some causes of cognitive decline may be treatable or partly reversible.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Dementia is diagnosed through a combination of medical history, assessment of symptoms, physical examination, and testing of memory and other cognitive abilities. Healthcare professionals may use blood tests to look for contributing conditions and may recommend brain imaging such as CT or MRI. Depending on the situation, neurological, genetic, or mental health evaluations may also be used. The evaluation aims to identify the type and possible underlying cause of cognitive decline.
Prevention
Key Prevention Tips
There is no proven way to prevent every form of dementia, particularly those caused by age-related or genetic changes
However, maintaining a healthy lifestyle may help address some modifiable risk factors
Managing blood pressure, diabetes, and cardiovascular health, avoiding tobacco, limiting excessive alcohol use, remaining physically active, and maintaining social and mental activity may support overall brain health
Early evaluation of persistent cognitive changes can also help identify treatable contributing conditions
