Sudden Onset of Weakness

Sudden Onset of Weakness

1. physiology of cerebral blood flow

   • myogenic regulation
   • neurogenic regulation
   • flow / metabolism neural coupling

2. headaches

   • primary
     • cluster
     • tension
     • Migraine
   • secondary
     • tumor
     • hematoma
     • Meningitis
     • post traumatic

3. facial nerve lesion

   • UMNL
     • lesion above the facial nuclei
     • it cause contralateral droop of the lower muscles of facial expression
   • LMNL
     • lesion below the facial nuclei
     • it cause paralysis in the upper and lower muscles of the facial expression in the same side

4. strokes

   • signs and symptoms
     • NUMBNESS or weakness of face
     • Sudden CONFUSION, trouble speaking
     • dizziness
     • HEADACHE
   • Differential diagnosis
     • intracranial hemorrhage
     • transient ischemic attack
     • seizure
   • risk factors
     • Modifiable
       • smoking

     • DVT
     • Depression
     • Chronic headaches
     • Dysphasia
   • Management
     • Rehabilitations
       • repetitive practice And to practice those skills impaired due to the stroke
       • SPEECH-LANGUAGE THERAPY
       • PHYSICAL THERAPY
       • PHYSICAL THERAPY OCCUPATIONAL THERAPY
       • NEUROLOGICAL THERAPY
     • Primary
       • Determine whehter the lesion is ischemic or hemorrhagic
         • ischemic
           • IV tPA
           • Aspirin
         • hemorrhagic
           • surgery
