Evolving Concept ofDegeneration:

Not Aging and Normal Disorder Processes

▶ Lack of vital endurance ▶ Premature death

Pathology of Cell Death:

Necrosis an injured cell form which results in the premature death of cells in living tissue by autolysis.

It’s caused by external factors.

Apoptosis a process of programmed cell death

lead to characteristic cell changes and death.

Apoptosis and Degeneration:

Degeneration Disorders are more rapid neuronal loss, associated with deposition of

degenerative products

appear in cell molecular mechanism [normal] [apoptosis]

Degenerative Products: protein aggregation and inclusion body formation

[Characteristic Neurodegenerative Diseases involved Deposition of Abnormal Protein Aggregation]

Transmissible Spongiform Encephalopathies[ Incidence ]

Bovine Spongiform Encephalopathy (BSE) relates to TSE brain form1st Detection: 1980s in Great Britain

Huntington’s Disease

Atrophy

Usually age 35 – 45 (+ or – 17 years)

Men and women equally

Younger people with Huntington's disease often have more severe case, and symptoms may progress more quickly
