true

seizures are divided into two broad categories: generalized and partial (also called local or focal).

true

Generalized seizures are produced by electrical impulses from throughout the entire brain

true

partial seizures are produced (at least initially) by electrical impulses in a relatively small part of the brain.

"Grand Mal" or Generalized tonic-clonic

Unconsciousness, convulsions, muscle rigidity

Absence Seizure

short loss of consciousness (just a few seconds) with few or no symptoms. The patient, most often a child, typically interrupts an activity and stares blankly. These seizures begin and end abruptly and may occur several times a day. Patients are usually not aware that they are having a seizure, except that they may be aware of "losing time."

Myoclonic Seizure

sporadic jerks, usually on both sides of the body. Patients sometimes describe the jerks as brief electrical shocks. When violent, these seizures may result in dropping or involuntarily throwing objects.

Clonic Seizure

repetitive, rhythmic jerks that involve both sides of the body at the same time.

Tonic Seizure

Muscle stiffness, rigidity

Atonic Seizure

sudden and general loss of muscle tone, particularly in the arms and legs, which often results in a fall.

Linear skull fractures

blunt trauma

Depressed skull fractures

high-energy transfer, such as a blow from a baseball bat

Basilar skull fractures

Caused by a blow to the back of the head, characteristic signs: blood in the sinuses; a clear fluid called cerebrospinal fluid (CSF) leaking from the nose or ears; raccoon eyes

Intracranial hemorrhages

dural and arachnoid membranes and their associated blood vessels are readily torn by the impact and fractured bone fragments

Subdural hemorrhage

gap between the dura and the cortical surface of the brain.

4 things that protect the brain

meningies, csf, blood-brain barrier, skull

nsg intervention for spinal injury

vitals/turn freq/call light close/ ROM

acceleration injury

head is suddenly forced to stop or start moving, or to turn rapidly.

deceleration injury

collision between a rapidly moving body part and a stationary object
