Alzheimer's and Dementia

In the United States, approximately 5.7 million people are living with some form of dementia.

In Illinois, there were approximately 220,000 people living with Alzheimer's disease in 2018; that number is projected to increase by 18.2% by the year 2025, to 260,000.

Dementia is defined as a decline in mental ability that is severe enough to impact an individual's daily life. This means having new problems with everyday activities and may or may not include memory dysfunction.

Dementia is the term for a group of symptoms that occur when the brain is damaged by disease. A diagnosis of dementia requires impairment in 2 or more core mental functions: memory, language skills, visual perception, ability to focus and pay attention, ability to reason and solve problems. There is no cure for dementia; progressive mental and cognitive decline is inevitable.

If you suspect a loved one is living with dementia, early diagnosis can provide an opportunity for early interventions and care and allow the individual to participate in the decision-making process. Always seek the counsel of a healthcare provider, since some conditions presenting as dementia are reversible, such as: infections and immune disorders, diet, chemical imbalances, mismanagement of medicines and/or drug interactions, alcohol abuse, depression, toxins, carbon monoxide, isolation/sensory deprivation.
