What awareness patterns indicate?
What awareness patterns indicate?
Patterns of awareness or responsiveness an indication of the extent of damage.
What is a vegetative state?
What is a vegetative state?
Absence of responsiveness and awareness due to overwhelming dysfunction of the cerebral hemispheres.

Study Notes
- Awareness
Brain Destruction
- Brain destruction can be caused by a number of things.
- Patterns of brain destruction give indications to the extent of damage someone has.
- Vegetative state is the absence of responsiveness and awareness caused by overwhelming dysfunction of the cerebral hemispheres.
- The diencephalon and brain stem may have sufficient sparing to preserve autonomic and motor reflexes, as well as sleep and wake cycles.
- Locked-in syndrome patients are aware but cannot move or communicate verbally because of complete paralysis except for blinking and eye movements.
Types of Delirium
- Hyperkinetic
- Hypokinetic
- Agnosia
- Dyspraxia
- Dysphasia
- Aphasia
Alzheimer's
- Extracellular deposits of beta amyloids and intracellular accumulation of tau protein are both compounds are insoluble.
- These compounds are characteristics of Alzheimer's disease
Delirium
- No structural changes to the brain
- Follows a time pattern with an abrupt upset
- Short duration
- Typically a temporary event
- Usually reversible
Dementia
- Group of cognitive disorders
- Gradual onset that progresses over time
- Involves death of brain cells or permanent damage of the neurons
Alzheimer's vs Delirium
- Alzheimers is a common form of dementia
- Unlike dementia, delirium has a disturbed sleep cycle

Description
This covers brain destruction, types of delirium, Alzheimer's disease, and general delirium information. Brain destruction patterns indicate the extent of damage. Alzheimer's is characterized by extracellular beta amyloids and intracellular tau protein. Delirium involves no structural brain changes and follows a time pattern.
