Study Notes
Types of Dementia
- Dementia is a term that describes a group of symptoms resulting from a progressive decline in cognitive function.
- The only way to determine the type of dementia a person has is through an autopsy after death.
Characteristics of Dementia
- Symptoms depend on the areas of the brain damaged and the extent of the damage.
- Most forms of dementia affect older people and last for years, ultimately leading to death.
- As brain cells become damaged, the person gradually loses the ability to remember, think, and use language.
- Physical abilities are lost, and the person becomes totally dependent on others for care.
Alzheimer's Disease
- Accounts for more than 50% of all dementias.
- Caused by plaques (abnormal sticky clumps of amyloid, a protein) and tangles (twisted protein fibers within nerve cells) building up in the brain.
- Characteristics include progressive memory loss, difficulties with thinking, problem-solving, and performing familiar tasks.
- Problems recognizing people and objects, loss of language skills, and personality changes.
- Lasts on average 8 to 12 years, usually occurring after age 60, with risk increasing with advanced age.
- A rare form (early-onset Alzheimer's disease) can occur between ages 30 and 60.
Other Key Facts
- Some medications have helped slow the progression of symptoms, but they do not work for everyone and are not useful in all forms of dementia.
- Dementia ultimately robs the person of all memories, personality, and abilities, leading to death.
- Despite widespread research, there is still no cure for dementia.
