Multiple sclerosis- most common CNS disorder; loss of myelin, autoimmunity or viral infections, can lead to immobility; no known cure, research with interferons 2. Meningitis- inflammation of meninges (arachnoid layer), caused by bacteria (worse kind) or virus, can 3. Hydrocephalus- CSF gets blocked in ventricle or arachnoid layer, pressure causes brain damage, drain 4. Schizophrenia- genetic; overabundance of dopamine; common symptoms are thought disturbance, withdrawal, hallucinations, grandiosity, anxiety, depression; drug treatment 5. Stroke- neurons destroyed from hemorrhage/ ischemia, can lead to paralysis if motor neurons destroyed, 6. Dementia- degeneration of nerves in brain; affects memory, attention span, intellectual capacity, 7. Headache- pressure in blood vessels around head and neck; electrical and/or chemical instability in neurons such as lack of serotonin, sends pain messages to brain; drug treatment such as ibuprofen – analgesic anti-inflammatory 8. Migraine- type of tension headache, genetic; symptoms include nausea, vomiting, increased sensitivity to light, sound, smell; drug treatment such as beta-blockers (preventative), antidepressants, calcium channel blocker, methysergide (anti-inflammatory), divalproex sodium (seizure medicine) 9. Alzheimer’s disease- destruction of cerebrum, lack of acetylcholine, form neural plaques – lesions on cortex; causes debated from genetic to environmental; prevent by low b.p. and cholesterol; leads to dementia 10. Huntington’s disease- genetic, autosomal dominant gene on chromosome IV; cerebrum degenerates in cortex, ventricles, and basal ganglia; leads to tremors and dementia; appears in older people, usually past 40 11. Parkinson’s Disease- destruction of substantia nigra in diencephalon, lack dopamine, affects voluntary muscles – tremors, use L-dopa treatment, research with fetal cells/ stem cells 12. Cerebral Palsy- nerve damage from prenatal infection, head trauma, poisons, anoxia; involuntary muscle control lost – paralysis; use muscle relaxants for treatment 13. Spina Bifida- birth defect in spine, leads to paralysis, take folic acid during pregnancy, surgery 14. Seizures- convulsions, cycles of brain circuitry abnormal, bursts of neuron activity; change in consciousness, motor control, sensory perception; treatments include anti-convulsants 15. Epilepsy- chronic seizures; drugs used to block neurotransmitters such as chlorine transport receptors 16. Depression- lack of neurotransmitters such as norepinephrine, dopamine, serotonin, etc.; SIGECAPS: 5 or fewer symptoms; drug treatment such as Prozac, Zoloft, Paxil 17. Bipolar Disorder- AKA manic depression; mental illness, mood swings – Highs and Lows; imbalance of neurotransmitters; SIGECAPS: 6 or more symptoms; drug treatment
