Definition
degenerative disease in motor neurons in the spinal cord and brainstem; motor neuron disease
Term
epilepsy
Definition
chronic brain disorder characterized by recurrent seizure activity
Term
seizure
Definition
abnormal, sudden exessive discharge of electrical activity within the brain
Term
tonic-clonic seizures (ictal events)
Definition
sudden loss of consciousness with stiffening (tonic contractions and then clonic contractions (twitching)-often preceded by aura
Term
absence seizures (petit mal seizures)
Definition
minor form of seizure--clouding of consciousness and loss of contact with environment momentarily
Term
multiple sclerosis
Definition
destruction of myelin sheath on neurons in CNS and its replacement by plaques of sclerotic tissue
Term
myasthenia gravis
Definition
neuromuscular disorder characterized by weakness of voluntary muscles
Term
palsy
Definition
paralysis
Term
parkinson disease
Definition
degeneration of nerves in basal ganglia, occuring in laterl ife and leading to tremors, weakness of muscles and slowness of movement
Term

gliomas--a type is an astrocytoma. Gliobastoma multiforme is most malignant form of astrocytoma -- Meningioma--usually benign--however cause compression of brain--they are surrounded by a capsule
Term
cerebral concussion
Definition
brief loss of consciousness after injury, usually clears within 24 hrs., no evidence of structural damage--more severe may lead to coma
Term
cerebral contusion
Definition
bruising of brain tissue as result of direct trauma to head--neurological deficits persist for more than 24 hours--usually associated with a skull fracture--subdural and epidural hematomas occur and can lead to permanent brain injury and epilepsy
Term

Term
embolic
Definition
a dislodged thrombus (embolus) travels to cerebral arteries and occludes (blocks) small vessel; occurs suddenly
Term
hemorrhagic
Definition
blood vessel breaks and bleeding occurs; can be fatal
Term
to treat thrombotic stroke
Definition
clot dissolving (anticoagulant) drug therapy--(tPA--tissue plasminogen activator) if started within 3 hours of onset of stroke; also surgically treated with a carotid endarterectomy (removal of plaque from inner lining of carotid artery)
Term
