According to the CDC website, dementia is not a specific disease, but it's rather a general term for the impaired ability to remember, think, or make decisions that interfere with everyday activities. Alzheimer's Disease is the most common type of dementia. Though Dementia, mostly affects older adults, it is not a part of normal aging.


Dementia is the loss of cognitive functioning, thinking, remembering, and reasoning to such an extent that it interferes with a person's daily life in activities.

Some people with dementia cannot control their emotions, and their personalities may change. Dementia ranges in severity from the mildest stage, when it is just beginning to affect persons functioning, to the most severe stage, when the person depends completely on you and others for basic activities of daily living, such as feeding oneself.




According to the mayo clinic.org website, dementia is a term used to describe a group of symptoms, affecting memory, thinking, and social abilities, severely enough to interfere with your daily life. It isn't a specific disease, but several diseases can cause dementia. Alzheimer's disease is the most common cause of progressive dementia in older adults, but there are a number of other causes of dementia. Depending on the cause, some dementia symptoms might be reversible. Www.mayoclinic.org


Dementia is an umbrella term used to describe a range of neurological conditions affecting your brain to get worse over time. It is the loss of the ability to think, remember, and reason to levels that affect only life and activities. Some with dementia cannot control their emotions and other behaviors, and their personality may change.





Dementia is a non-specific clinical syndrome that involves cognitive impairments of sufficient severity to interfere with social or occupational functioning. It involves at least two areas of affected cognition – memory, language, reasoning, attention, perception, or problem-solving. Memory loss alone is not necessarily dementia as there can be many causes of memory loss. Among the most common types of dementia are Alzheimer’s disease, Lewy body dementia, frontotemporal dementia, and vascular dementia.




Dementia is a loss of mental functions that is severe enough to affect your daily life and activities. These functions include:

  • Memory

  • Language skills

  • Visual perception (your ability to make sense of what you see)

  • Problem-solving

  • The trouble with everyday tasks

  • The ability to focus and pay attention

It is normal to become a bit more forgetful as you age. But dementia is not a normal part of aging. It is a serious disorder that interferes with your daily life.
