typical migraine symptoms
unilateral, fronto-temporal, throbbing pain in head often is worse behing one eye or ear. accompanies by sensitive scalp, anorexia, photophobia, phonophobia, and nausea with or without vomiting.
most common type of chronic long-duration headache with pain lastine more than 4 hours
abnormal, sudden, excessive, uncontrolled electrical discharge of neurons within th ebrain that may result in a change in LOC, motor or sensory ability, and or behavior
two or more seizure experienced by a person, it is a chronic disorderin which repeated unprovoked seizure activity occurs
lasts 2-5 minutes beginning with a tonic phase that causes stiffening or rigidity of the muscles, and immediate loss of consciousness, clonic or rhythmic jerking of all extremities follows
brief periods of loss of consciousness and blank staring as though the person is daydreaming, the person's eyes may flutter
brief jerking or stiffening of the extremities that may occur singly or in groups, lasting for just a few seconds
atonic (akinetic) seizure
patient has a sudden loss of muscle tone, lasting for seconds, followed by postictal (after the seizure) confusion. in most cases, these seizures cause the patient to fall, which may result in injury.
complex partial seizure
LOC or "black out" for 1-3 minutes. the patient is unaware of environment and may wander at the start of seizure. after seizure patient may experience amnesia. temporal lobe is most involved
simple partial seizure
remains conscious throughout the episode. patient often reports an aura before seizure. patient may have one-sided movement of an extremity, change in heart rate, skin flushing, and epigastric discomfort
be sure oxygen and suctioning equipment with an airway are readily available, maintain iv acess, siderails up at all times
most common type, results from measles, mumps, herpes simplex, and herpes zoster, and other viral infections. No organisms are obtained in the CSF, clinical manifestations include: fever, phototopia, headache, myalgias, nausea
medical emergency with mortality rate of 25%, occurs in areas of high population density in fall or winter, causes formation of exudate
key features is patient's with meningitis
change in LOC, disorientated to person, place, time, abnormal eye movements, shortened attention span, behavior/personality changes, severe headaches, generalized muscle aches, fever and chills, nausea, vomiting, tachycardia, red macular rash
most important nursing intervention for patients with meningitis
accurate monitoring and recording of their neurologic status, vital signs, vascular assessment
inflammation of brain tissue and often the surrounding meninges, affectin gthe cerebrum, brainstem, and cerebellum
patho of encephalitis
virus infades brain tissue via bloodstream. inflammation extends over cerebral cortex causing degeneration of neurons of the cortex. demyelination of axons occurs, this leads to hemmorhage, edema, necrosis, and development of cavities in cerebral hemispheres
clinical manifestations of encephalitis
high fever, changes in mental status, motor dysfunction, focal neurological deficits, phototopias, fatigue, symptoms of increasing ICP
Nursing intervention for encephalitis
maintain a patent airway to prevent the development of atelectasis or pneumonia which can lead to further brain hypoxia
is a progressive neurodegenerative disease that is the third most common neurologic disorder of older adults
Parkinson's disease is characterized by four cardinal symptoms:
tremor, rigidity, bradykinesia or akinesia, and postural instability.
chronic, progressive, degenerative disease that accounts for 60% of dementias occurring in people older than 65 years old
hereditary disorder transmitted as an autosomal dominant trait at the time of conception. This movement disorder causes both neurologic and behavioral symptoms
two main symptoms of HD:
progressive mental status changes, leading to dementia, and choreiform movements (rapid, jerky movements)
