CHINUN B . [B . CH INUN@GMAIL .COM ]
Contents: 7 Neuronal Diseases
◉ Transmissible Spongiform Encephalopathies
◉ Parkinson's Disease ◉ Huntington’s Disease ◉ Alzheimer’s Disease ◉ Amyotrophic Lateral Scierosis ◉ Multiple Scierosis ◉ Korsakoff’s Syndrome
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[ Pathology ]
Transmissible Spongiform Encephalopathies[ Incidence ]
Bovine Spongiform Encephalopathy (BSE) relates to TSE brain form1st Detection: 1980s in Great Britain
Transmissible Spongiform Encephalopathies[ The Origin and cause ]
Prion Protein

[ The Origin and cause ]
Lewy Bodies & Misfolded Proteins Parkinson’sDisease

Huntington’s Disease
Huntington’s Disease[Pathology]
[ Symptoms]
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
