Answer 15

Deep brain stimulation - by electrode in the thalamus is adjustable and reversible, ablation - has been used but is replaced by deep brain stimulation, transplantation -Fetal neural tissue which provides dopamine producing cells

Question 16

Nutritional therapy for Parkinson’s disease

Answer 16

Food that’s easily chewed and swallowed. Roughage and fruit to avoid constipation. Six small meals per day.

Question 17

Define myasthenia gravis

Answer 17

In autoimmune disease of the neuromuscular junction characterized by the fluctuating weakness of certain skeletal muscle groups

Question 18

Etiology of myasthenia gravis

Answer 18

Autoimmune process in which antibodies attack acetylcholine receptors preventing muscle contraction

Question 19

Clinical manifestations of myasthenia gravis

Answer 19

Fluctuating weakness of skeletal muscle, eyes, eyelids, chewing, swallowing, speaking, breathing, muscles are strongest in the morning but weak by end of the day

Question 20

What is a myasthenic crisis and what triggers one

Answer 20

It is an acute exacerbation of muscle weakness. Triggered by infection, surgery, emotional distress, drug overdose, inadequate drugs.

Question 21

Diagnostic studies for myasthenia gravis

Answer 21

Diagnosis is based on history and physical. If diagnosis still in doubt EMG or Tensilon test maybe used.

Question 22

Drug therapy for myasthenia gravis

Answer 22

Corticosteroids suppress the immune response, anticholinesterase drugs enhance the function of the neuromuscular junction

Question 23

Surgical therapy for myasthenia gravis

Answer 23

Removal of the finest gland - thymectomy

Question 24

Other therapies for myasthenia gravis

Answer 24

Plasmapheresis is a short-term improvement indicated for patients in crisis or preparation for surgery

Question 25

Define amyotrophic lateral sclerosis ALS

Answer 25

Hey where progressive neurologic disorder characterized by loss of motor neurons

Question 26

ALS (Lou Gehrig's disease) life expectancy

Answer 26

Death within 2 to 6 years

Question 27

ALS etiology/pathophysiology

Answer 27

For unknown reasons, motor neurons in the brain stem and spinal cord gradually degenerate leading to weakness of upper extremities, dysarthria, dysphagia, muscle wasting and fasciculations, Pain, sleep disorders, spasticity, drooling, emotional lability, depression, constipation, esophageal reflux, devastating because patient remains cognitively intact while wasting away.
