Changes in the brain and nervous system occurs:
with aging and desease
Nervous system changes from aging:
- nerve cells are lost
- nerve conduction slows
- reflexes, responses and reaction times are slower
- vision, hearing, taste, smell and touch decrease
- sensitivity to pain decrease
- blood flow to the brain is reduced
- sleep patterns change
- memory is shorter, forgetfulness occurs
-dizziness can occur
Delirium occurs suddenly:
usually temporally
causes include:
-infection, drugs, illness, surgery, injury
treatment is aimed at cause
Is dementia hereditary?
Yeah it is
Early warning signs of dementia:
- Recent memory loss that affects job skills
- Problems with common tasks

- Getting lost in familiar places
- Misplacing things and putting things in odd places
- Personality changes
- Poor or decreased judgment
- Loss of interest in life
Types of permanent dementia:
- Alzheimer’s disease (most common)
- vascular dementia (stroke or other blood vessel problems damage vessels that supply blood to the brain)
- Lewy body dementia (abnormal protein deposits in the brain, lewy bodies affect chemicals in brain)
-Fronto-temporal disorders (nerve cells in certain areas of the brain [front and sides] break down) - Mixed dementia (2 or more types of dementia occur together)
Treatable causes of dementia:
- Drugs and alcohol
- Delirium and depression
- Tumors
- Heart, lung, and blood vessel problems
- Head injuries
- Infection
- Vision and hearing problems
Alzheimer’s disease functions affected:
- Memory
- Thinking
- Reasoning
- Judgment
- Language
- Behavior
- Mood
- Personality
What happens to the brain with alzheimer’s
Many brain cells are destroyed and die
connections between nerve cells are lost
brain shrinks from nerve cell death and tissue loss
Two abnormal structures are thought to cause damage in alheimer’s
Plaques- protein that build up in the spaces between nerve cells
Tangles- twisted protein fibers that build up inside cells
Dementia age group
65+
Alzheimer’s age group
60+
