Dementia Glossary
Understanding Alzheimer's Disease: A Comprehensive Glossary
Welcome to the Dementia Glossary provided by Social Service of America, a leading philanthropy organization dedicated to making a positive impact within our community and society. In this comprehensive glossary, we aim to provide you with a detailed understanding of the various terms associated with Alzheimer's disease, a common form of dementia.
What is Dementia?
Dementia refers to a range of cognitive impairments that affect memory, thinking, and social abilities, resulting in a decline in daily functioning. Alzheimer's disease is the most common cause of dementia, accounting for approximately 60-80% of cases. This glossary aims to demystify the complex terminology surrounding dementia and Alzheimer's.
Dementia Glossary
Below, you will find an extensive list of terms related to dementia and Alzheimer's disease, each explained in detail:
1. Alzheimer's Disease
Alzheimer's disease is a progressive brain disorder that causes memory loss, cognitive decline, and behavioral changes. It is characterized by the accumulation of amyloid plaques and neurofibrillary tangles in the brain.
2. Amyloid Plaques
Amyloid plaques are abnormal protein deposits that build up between nerve cells in the brain of individuals with Alzheimer's disease. These plaques are primarily composed of beta-amyloid protein fragments.
3. Neurofibrillary Tangles
Neurofibrillary tangles are twisted fibers of tau protein that form inside brain cells. They are a hallmark of Alzheimer's disease and disrupt the normal functioning of neurons.
4. Mild Cognitive Impairment (MCI)
Mild cognitive impairment (MCI) refers to a stage between normal age-related cognitive decline and dementia. Individuals with MCI may experience memory or thinking problems beyond what is expected for their age, but the symptoms are not severe enough to interfere with daily activities.
5. Vascular Dementia
Vascular dementia is caused by impaired blood flow to the brain, often due to a stroke or other vascular conditions. It is the second most common type of dementia after Alzheimer's disease and is characterized by difficulties with planning, judgment, and reasoning.
6. Lewy Body Dementia (LBD)
Lewy body dementia (LBD) is a progressive form of dementia caused by the presence of abnormal clumps of alpha-synuclein protein, known as Lewy bodies, in the brain. It shares similarities with both Alzheimer's disease and Parkinson's disease.
7. Frontotemporal Dementia
Frontotemporal dementia (FTD) is a group of disorders characterized by the progressive degeneration of the frontal and temporal lobes of the brain. It often affects behavior, personality, and language abilities.
8. Sundowning
Sundowning refers to the worsening of behavioral and psychological symptoms of dementia, such as restlessness, confusion, and agitation, that often occur in the late afternoon or evening.
9. Caregiver Burnout
Caregiver burnout refers to the physical, emotional, and mental exhaustion experienced by individuals caring for someone with dementia. It can result from prolonged stress, constant caregiving responsibilities, and a lack of support.
10. Respite Care
Respite care provides temporary relief to caregivers by allowing trained professionals to take over caregiving duties temporarily. It offers caregivers the opportunity to rest, recharge, and attend to their own needs.
Conclusion
We hope that our Dementia Glossary has provided you with a comprehensive understanding of the terms associated with Alzheimer's disease and other forms of dementia. By familiarizing yourself with these terms, you can better navigate the complexities of dementia and advocate for the well-being of those affected. At Social Service of America, we are committed to supporting individuals and families impacted by dementia through our philanthropic efforts. Together, let's work towards a future where effective treatments and prevention strategies allow individuals to enjoy a better quality of life.
