  inflammatory vesicles along peripheral nerves

3
Neuralgia

• Sudden, sharp, severe stabbing pain along a nerve
  pathway

4
Bells Palsy

• Unilateral facial paralysis, sudden onset, viral

6
Meningitis

• Bacterial or viral inflammation of meninges,
  causes headache, fever, sore throat, back and

7
Epilepsy

• Idiopathic recurring and excessive electrical

Hydrocephalus

• Increased accumulation of CSF within the
  ventricles of the brain, causes cranium to
  enlarge unless treated to remove excess fluid

9
Parkinsons disease

• Tremors, uncontrolled shaking, related to
  decreased amounts of dopamine in the brain

10
Cerebral palsy

• Congenital brain disorder causing damage to motor
  neurons, flaccid or spastic paralysis

11
Multiple Sclerosis

• Autoimmune, destroys myelin around spinal cord
  with progressive deterioration

12
Muscular dystrophy

• Genetic defect in muscle metabolism, causes
  progressive atrophy

13
Alzheimers Disease

• Not all timers or old timers disease
• Dementia producing lesions in the brain

14
Stroke (CVA) Cerebrovascular Accident

• A blockage of blood flow to an area of the brain
  caused by either a blood clot or aneurysm (bleed)
• TIA- Transient ischemic attack- small stroke
  occurs when the blood flow is blocked for a short
  amount of time, creating signs and symptoms that
  then disappear when the blood returns
