Also known as senility, rare dementia

Dementia is a syndrome, often associated with neurodegenerative diseases such as Alzheimer's, and characterized by a general decline in cognitive abilities that affects a person's ability to perform everyday activities. This typically involves problems with memory, thinking, behavior, and motor control. Aside from memory impairment and a disruption in thought patterns, the most common symptoms of dementia include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Dementia is an incurable, prog

AI overview

Dementia is a condition involving a general decline in cognitive abilities—including memory, thinking, behavior, and motor control—that makes it harder for people to perform everyday activities. It matters because it's an incurable, progressive condition that can cause emotional problems, language difficulties, and decreased motivation, typically developing across several stages.

Dementia is a syndrome, often associated with neurodegenerative diseases such as Alzheimer's, and characterized by a general decline in cognitive abilities that affects a person's ability to perform everyday activities. This typically involves problems with memory, thinking, behavior, and motor control. Aside from memory impairment and a disruption in thought patterns, the most common symptoms of dementia include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Dementia is an incurable, progressive neurocognitive disorder, with varying degrees of severity (mild to major) and many forms or subtypes. The condition has a significant effect on the individual, their caregivers, and their social relationships in general. Dementia is not the same as age-related decline in cognition and memory, with no change in intelligence.

The most common form of dementia is Alzheimer's. Dementia can be caused by brain injuries and stroke. It has also been described as a spectrum of disorders with subtypes of dementia based on which known disorder caused its development, such as Parkinson's disease for Parkinson's disease dementia, Huntington's disease for Huntington's disease dementia, vascular disease for vascular dementia, HIV infection causing HIV dementia, frontotemporal lobar degeneration for frontotemporal dementia, Lewy body disease for dementia with Lewy bodies, and prion diseases. Subtypes of neurodegenerative dementias may also be based on the underlying pathology of misfolded proteins, such as synucleinopathies and tauopathies. The coexistence of more than one type of dementia is known as mixed dementia.
