Transcript of Alzheimer's disease

Alzheimer's Disease
Alzheimer's disease (AD) is the most common form of dementia. There is no cure for the disease, which worsens as it progresses, and eventually leads to death. It was first described by Alois Alzheimer in 1906 .
5. Poor or decreased judgment.
The disease course is divided into four stages, with progressive patterns of cognitive and functional impairments.
1. Pre-dementia
2. Early
3. Moderate
4. Advanced
The early symptoms can affect the most complex daily living activities. Rare problems with the executive functions of attentiveness, planning, flexibility, and abstract thinking, or impairments in semantic memory (memory of meanings, and concept relationships) can be symptomatic of the early stages of AD.
Difficulties with language, executive functions, perception , or execution of movements are more prominent than memory problems.
Language problems are mainly characterized by a shrinking vocabulary and decreased word fluency, which lead to a general impoverishment of oral and written language.
Although Alzheimer's disease develops differently for every individual, there are many common symptoms. Early symptoms are often mistakenly thought to be 'age-related' concerns, or manifestations of stress
People with Alzheimer’s experience difficulties communicating, learning, thinking and reasoning — problems severe enough to have an impact on an individual's work, social activities and family life.
7. Misplacing things.
3. Problems with language.
1. Memory loss.
9. Changes in personality.
2. Difficulty performing familiar tasks.
4. Disorientation to time and place.
6. Problems with abstract thinking.
8. Change in mood or behavior.
10. Loss
of initiative.
Speech difficulties become evident which leads to frequent incorrect word substitutions. Reading and writing skills are also progressively lost. Complex motor sequences become less coordinated as time passes and AD progresses, so the risk of falling increases.
During the final stage of AD, the person is completely dependent upon caregivers. Language is reduced to simple phrases or even single words, eventually leading to complete loss of speech. Although aggressiveness can still be present, extreme apathy and exhaustion are much more common results. They lose complete control on their muscles. AD is a terminal illness, with the cause of death typically being an external factor


During this phase, memory problems worsen, and the person may fail to recognize close relatives. Long-term memory becomes impaired. Behavioral and neuropsychiatric changes become more prevalent.
