1. Types of peripheral neuropathy Sensory Motor Autonomic Combined i.e. diabetic neuropathy i.e. Guillain-Barré i.e. Dysautonomia, diabetic autonomic neuropathy Most peripheral neuropathies

2. Guillain-Barré Syndrome Acute peripheral neuropathy, mostly motor Preceded by a viral infection Etiology is suspected to be autoimmune Severe cases may produce respiratory failure, even death Most cases completely resolve spontaneously in 6-12 months

3. Classification of traumatic brain injury Mild Moderate Severe UnconsciousnessAmnesia <1 hour<1 day 1-24 hours1-7 days >24 hours>7 days Abnormalities in brain images Absent Present

4. Levels of affectation in spinal cord injuries Above C4: Requires ventilator C4-T1: Different degrees of command of arms/hands T2-T12: Paraplegia L1-S5: Some sensory/motor loss in legs/hips

5. Brown-Séquard syndrome Same side of lesion: - Motor loss - Numbness to touch and vibration Opposite side of lesion: - Loss of pain - Loss of temperature sensation

6. Autonomic dysreflexia

7. Arterial blood supply of the brain

8. Ischemic stroke Vs Hemorragic stroke Atherosclerosis in arteries that feed the cerebral circulation In situ formation of a blood clot on Top of the atherosclerotic plaque Cerebral artery Direct obstruction Carotid artery Embolization to the brain Lack of oxygen in an area of the brain Neuronal death Neurological deficit Rupture of a blood vessel within the CNS: Aneurism in a cerebral artery Arterial-venous malformation Bleeding from the meninges Sub-arachnoideal hemorrage Epidural hematoma Subdural hematoma/ Intraparenchymal hemorrage Inflammatory reaction to the presence of blood Mechanical pressure from blood in closed space

9. Etiology of ischemic stroke
