Mild Cognitive Impairment (MCI) is a condition characterized by noticeable cognitive decline that is greater than expected for a person's age, but not severe enough to interfere significantly with daily life or independent function. It is often considered an intermediate stage between normal cognitive aging and more serious conditions like dementia, and can sometimes progress to Alzheimer's disease or other types of dementia.

Mild Cognitive Impairment

Cognitive decline refers to the gradual deterioration of cognitive abilities, including memory, reasoning, and problem-solving skills, often associated with aging or neurological disorders. It can significantly impact daily functioning and quality of life, making early detection and intervention crucial for managing its effects.

Alzheimer's disease is a progressive neurodegenerative disorder characterized by memory loss, cognitive decline, and behavioral changes, primarily affecting older adults. It is the most common cause of dementia, with complex pathophysiology involving amyloid-beta plaques, tau tangles, and neuroinflammation, leading to neuronal death and brain atrophy.

Alzheimer's disease

Dementia is a broad category of brain diseases that cause a long-term and often gradual decrease in the ability to think and remember, significantly affecting daily functioning. It is not a single disease but a syndrome that involves a decline in memory, reasoning, or other cognitive skills, often accompanied by changes in mood, perception, and behavior.

Serious conditions refer to medical or health issues that pose significant risk to an individual's well-being, potentially leading to severe complications or death if not properly managed. These conditions often require immediate attention, specialized treatment, and ongoing management to mitigate risks and improve quality of life.
