Dementia is a syndrome, classed as a major neurocognitive disorder often associated with neurodegenerative diseases such as Alzheimer's, and characterized by a general decline in cognitive processes that affects the 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 disorder, with varying degrees of severity 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.
