Paroxysmal dysarthria
• Seizure vs TIA ?Etiology
• ?Reflex seizure
• ? Due to SDH
• ? Hyperglycemia induced seizure

mechanism of paroxysmal
dysarthria• Following hypothesis as to the mechanism of the
paroxysmal attacks:
• The fact that the attacks are an early symptom
suggests that they may correspond to the earlier
stages of demyelination/ axonal injury
• During this phase it may well be that the axons,
though still capable of functioning normally in the
various facilitating and inhibiting systems, become
very vulnerable to changes in the internal environment
and that some minor, and reversible, change might
cause them temporarily to suspend function, which
they resume as the change passes off.

• Appears to be highly sensitive to the effects of
overbreathing. Since overbreathing is known to
decrease cerebral blood flow , small fall in the
blood supply producing, presumably, a minor
degree of hypoxia, to which damaged neurones
are abnormally sensitive.
• Biochemical and/or vascular changes responsible
for transient neurological disturbances,
• Emotion / stress - vasospasm - triggers
symptoms

symptom:
• Stroke: cerebrovascular ischemic disorders
