Types of peripheral neuropathy

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

2. Guillain-BarréSyndrome 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 Abnormalities in brain images Unconsciousness Amnesia Absent Mild <1 hour <1 day Moderate Present 1-24 hours 1-7 days Severe Present >24 hours >7 days

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