Generally act by stabilizing nerve cell membranes and preventing spread of the epileptic discharge.
**Primary goal of antiseizure drugs is to obtain maximum seizure control with minimum amount of toxic side effects.
**Begin with single drug - loading dose (larger than usual dose) to bring blood to therapeutic level.
**Serum drug levels monitored for therapeutic range.
Seizures may be controlled with less than therapeutic level of med or greater than therapeutic level (if no side effects)
May need combination regimen

During a seizure, a person may injure himself or herself.
Nurse needs to assess for injury after seizure****
Seizure precautions are guidelines that a person can follow in order to minimize injury during a seizure. For any activity, it is important to ask, "What would happen if I had a seizure while doing this?"

Focus care on respiratory maintenance. The use of devices to assist in breathing includes machines that are only used at night as well as mechanical ventilation. Patients should discuss their wishes regarding artificial ventilation with their doctors.
Chronic disease characterized by fatigue and weakness primarily in muscles innervated by the cranial nerves as well as in skeletal and respiratory muscles.
Progressive autoimmune disease of the neuromuscular junction
Caused by an autoantibody attack on the acetylcholine receptors in the muscle end plate membranes.
Nerve impulses are not transmitted to the skeletal muscle at the neuromuscular junction.

Complication is respiratory failure
The immune system starts to destroy the myelin sheath that surrounds the axons between the nodes of Ranvier.
The result is dispersion of impulses and slow conduction.
difference between Guillian syndrome and MS
is that multiple sclerosis attacks the central nervous system, whereas in the Guillain-Barre syndrome, it is the peripheral nerves that are affected. The nerve damage is thought to be the result of an abnormal immune reaction directed against the myelin of the peripheral nervous system. Another difference is that Guillain-Barre syndrome does not recur except in rare instances.

Bell's palsy is a temporary form of facial paralysis. It results from lesion or damage to the nerve that controls movement of the muscles in the face.
Bell's palsy involves damage to the seventh cranial (facial) nerve. This nerve controls the movement of the muscles of the face. The cause is often not clear, although herpes infections may be involved.
Bell's palsy is thought to be linked to inflammation of the nerve in the area where it travels through the bones of the skull.
symptoms of bells palsy
Symptoms usually start suddenly, and range from mild to severe. They may include:
Twitching in face
Weakness in face
Face feels stiff or pulled to one side
Droopy eyelid or corner of mouth
Drooling due to inability to control facial muscles
Paralysis of one side of the face, makes it hard to close one eye
Change in facial expression (for example, grimacing)
Dry eye or mouth
Loss of sense of taste.
Difficulty with eating and drinking
Pain behind or in front of the ear, may occur 1-2 days before muscle weakness
Sensitivity to sound (hyperacusis) on the side of the face affected
treatment of Bells Palsy
In many cases, no treatment is necessary. The goal of treatment is to relieve the symptoms. Recovery usually occurs within a few weeks, without residual effects.
Corticosteroids or antiviral medications may reduce swelling and relieve pressure on the facial nerve. These drugs must be given early to be most effective (preferably within 24 hours of the symptoms starting).
ye drops or eye ointments
Frequent oral care
Chew on unaffected side
Surgery to relieve pressure on the nerve (decompression surgery) is controversial and has not been shown to routinely benefit people with Bell's palsy
