MULTIPLE SCLEROSIS Flashcards
is an immune-mediated, progressive demyelinating disease of the CNS.
Multiple Sclerosis
Damage of Multiple Sclerosis are irreversible or reversible?
Irreversible
It commonly affects 20 to 40 years old
Multiple Sclerosis
Serves as insulator
Myelin Sheath
Speeds the conduction of impulse along the axon
Myelin Sheath
Risk Factors of Multiple Sclerosis
-Genetics
-Environmental
-Smoking
- Lack of Vitamin D exposure
-Exposure to Epstein-Barr Virus
refers to the destruction of myelin
Demyelination
What involves in the destruction of myelin
Destruction involves the Schwann cells and Oligodendrocytes
What causes myelin sheath to occur?
Due to destruction of myelin sheaths
What will happen if the myelin sheath is destructive?
Flow of nerve impulses is interrupted and it may result to:
-Optic nerve damage
-Chiasm
-Tracts
-Cerebrum
-Brainstem and cerebellum
-Spinal Cord
Therefore, the motor, sensory, cerebellar and emotional are affected
Clinical Manifestations of Multiple Sclerosis
Charcot’s Neurologic Triad
-Scanning speech
-Intentional Tremors
- Nystagmus
Location of Plaque in Scanning Speech
Brainstem
Scanning Speech Effects on Conscious and Unconscious Movements
- Conscious Movements: Chewing problems
- Unconscious Movements: Dysphagia
