The statement that is least accurate about dementia from the given options is "Persons with dementia always suffer from aphasia." This statement is inaccurate because not all individuals with dementia suffer from aphasia, which is a condition that impairs one's ability to process language.
Although it is true that language can be affected in persons with dementia, it is not a guaranteed symptom for all individuals. The severity and progression of dementia varies greatly between individuals. In more severe forms of dementia, an individual may indeed suffer from aphasia and may not speak at all.
The progression and manifestation of symptoms in dementia is influenced by a variety of factors, including the underlying cause of the dementia, the individual's overall health, and the timeliness and effectiveness of treatment.
Furthermore, other conditions may also develop as dementia progresses, such as apraxia - a disorder of motor planning which can affect an individual's ability to perform learned movements. Therefore, while aphasia can be a symptom of dementia, it is not accurate to state that all persons with dementia always suffer from it.
Understanding the varied symptoms and experiences of individuals with dementia is vital for providing effective care and treatment. It is important to remember that each individual's experience with dementia is unique, and not all will exhibit the same symptoms or progress at the same rate.

In 2001, the Institute of Medicine published Crossing the Quality Chasm: A New Health System for the 21st Century. This report identified six goals for quality improvement in health care:
* Safe: Avoiding injuries to patients from the care intended to help them
* Effective: Providing services based on scientific knowledge to all who could benefit, and refraining from providing services to those not likely to benefit
* Patient-centered: Providing care that is respectful of and responsive to individual patient preferences, needs, and values, and ensuring that patient values guide all clinical decisions
* Timely: Reducing waits and sometimes harmful delays for both those who receive and those who provide care
* Efficient: Avoiding the waste of equipment, supplies, ideas, and energy
* Equitable: Providing care that does not vary in quality because of personal characteristics such as gender, ethnicity, geographic location, and socioeconomic status
