Alzheimer's Disease CAT Flashcards
What is Alzheimer’s?
A progressive neurological disorder that results in deterioration and irreversible damage in the cerebral cortex and subcortical areas of the brain
What structures are usually damaged with Alzheimer’s?
Neurons that are normally involved w/ ACh transmission deteriorate in the cerebral cortex
Other contributing factors to Alzheimer’s
- Low levels of neurotransmitters
- Higher levels of aluminum
- Genetic inheritance
- Autoimmune disease
- Abnormal processing amyloid
- Virus
What demographics are most susceptible to Alzheimer’s?
- Risk increases with age (80+)
- Females > males
Clinical presentation for early alzheimer’s
- Subtle changes in memory, impaired concentration, difficulty w/ new learning
- Loss of orientation, word-finding difficulties, emotional lability, depression, poor judgment, impaired self-care
Clinical presentation for mid-stage alzheimer’s
- Develop behavioral and motor problems
- Neurological symptoms (aphasia, apraxia, perseveration, agitation, wandering, and violent or socially unacceptable behavior)
Clinical presentation for end-stage alzheimer’s
- Severe intellectual and physical destruction
- Vegetative symptoms (incontinence, functional dependence, inability to speak, seizures)
Role of imaging in managing Alzheimer’s
- Diagnosis cannot be confirmed until postmortem biopsy to reveal changes to tissue
- MRI can be used to find abnormalities or signs of atrophy, OR rule out other conditions
- SPECT can be used to determine brain activity and predict potential for Alzheimer’s
- Lab values can be used to rule out other diseases
Risk is elevated for what conditions with end-stage Alzheimers?
- Infection and pneumonia
- Complications from vegetative state (contractures, ulcers, fracture, and pulmonary compromise)
How is Alzheimer’s managed pharmacologically?
- Goal is to inhibit AChesterase, alleviate cognitive symptoms, and control behavioral changes
- Usually short-term (6-9 months)
- Tacrine (cognex)
- Donepezil (aricept)
- Rivastigmine (exelon)
Tacrine (cognex)
acetylcholinesterase inhibitor
Donepezil (aricept)
- used to treat confusion related to Alzheimer’s disease.
- may improve memory, awareness, and the ability to function
Rivastigmine (exelon)
- used to treat confusion related to Alzheimer’s disease and to Parkinson’s disease
- may improve memory, awareness, and the ability to perform daily functions
What should the focus of physical therapy be with patients who have Alzheimers?
- Maximizing remaining function
- Provide family and caregiver education
- Modify living space to facilitate easily finding stuff
Long-term effects of alzheimer’s
- 4th leading cause of death in US
- Typical course of disease 7-11 years
- Infection or dehydration is usually how they will pass
