a genetic locking of the small bones in the middle ear, can be made worse by infections. Can be treated surgically.

Declining perceptual-motor skills can make driving a car difficult and contributes to decreasing mobility.

High stomach obesity, high triglycerides', abnormally high HDL & low LDD, high glucose.

natural selection has not eliminated many harmful conditions and nonadaptive characteristics in older adults.

•Evolution occurs on a time scale that does not lend itself to empirical study.
It fails to account for cultural influences

Leonard Hayflick's theory that the maximum number of times that human cells can divide is about 75 to 80

D N A sequences that cap chromosomes, become shorter each time a cell divides

people age because normal metabolic processes within cells produce unstable oxygen molecules that ricochet inside cells, damaging D N A and cellular structures

aging is caused by mitochondrial decay

Slowing in information processing is linked to the dings and dents in brain from living.

Neuronal Fallout
Plasticity model

Losses occur in numbers of neurons and synapses: loss of brain tissue

Decreases in prefrontal cortex, hippocampus, increases in white matter hypersensitivities. White matter decrease

Continued growth through dendritic elaboration

Diet and exercise preserve brain function and cognition

Mild Cognitive Impairment (MCI) Dementia Alzheimer's Disease Frontal Temporal Dementia

you are aware your memory or mental function has "slipped." May increase your risk of later progressing to dementia. Between normal aging and dementia.

A global term for several neurlogical disorders involving irreversible decline in mental function severe enough to interfere with daily living
