• Certain local anesthetics decrease membrane permeability to sodium ions link • generic phrase denoting functional disturbances and/or pathological changes in the peripheral nervous system • in excess of one hundred different causes of peripheral neuropathy (diabetes, medication, infections, autoimmune) • Symptoms include tingling, pain or numbness especially in the extremities and muscle weakness • Affects about 1% of population • Short, recurrent, periodic attacks of motor, sensory, or psychological malfunction • Attacks celled seizures • Initiated by abnormal, synchronous electrical discharges from brain • Many causes (brain damage, toxins, metabolic disturbances) link • Damaged by compression (tumor, herniated disc, blood clots, penetrating wounds, traumatic events) • Can lead to paralysis – Monoplegia- one extremity – Paraplegia- both lower extremities – Quadriplegia- both upper and lower extremities link • Shingles- infection of peripheral nervous system by herpes zoster virus – Pain, skin discoloration, line of skin blisters • Poliomyelitis- poliovirus attacks neuron cell bodies – Fever, headaches, stiff neck and back, pain and weakness – Can cause paralysis • Infection and swelling of the meninges (membrane that surrounds brain and spinal cord) • Can be viral or bacterial link • Congenital defect of vertebral column in which spinal cord protrudes through unfused vertebrae • Can produce paralysis • Can be tested prenatally • Afflicts about 11% of population over 65 • Deterioration of mind – Loss of neurons in specific regions – Abnormal plaque deposits – Tangled protein filaments in neurons • Diagnosis difficult link • Progressive disorder of CNS • Usually seen around age 60 • Changes in substantia nigra and basal ganglia • Too little dopamine produced (neurotransmitter) • Too much acetylcholine produced • Progressive destruction of myelin sheaths of neurons in CNS • Form scleroses (hardened scars or plaques) • Slows conduction • Average onset age 33 • Progressive loss of function interspersed with remission periods • Devastating, degenerative brain disorder for which there is, at present, no effective treatment or cure • Genetic- autosomal dominant (50% chance to pass to children) • neurological disorder characterized by tics -involuntary, rapid, • Abnormal sudden movements or metabolism of vocalizations that neurotransmitters occur repeatedly in the dopamine and same way serotonin are • Onset before the age involved of 18 • Genetically transmitted • Girls have a 70% chance of displaying symptoms, boys with the gene have a 99% chance of displaying symptoms. link • Progressive neurodegenerative disease that attacks nerve cells in brain and spinal cord • As neurons die, body functions lost (paralysis) • Brain usually stays intact link
