- generalized seizure
- Scar tissue that develops in the area of the seizure is called?
- gliosis
- Because gliosis has developed, what can occur?
- additional seizures
- Seizures are divided into two major classes. What are they?
- generalized and partial seizures
- What type of seizure is preceded by an aura or warning?
- Partial seizure

- Generalized seizure
- What type of seizure is a Akinetic seizure?
- Generalized seizure
- Partial seizures are divided into two categories. What are they?
-
1. Simple partial seizure
2. Complex partial seizure - Manifestations of a Tonic-clonic (generalized) seizure may include?
-
* LOC
* Falling to the ground
* Stiffening of the body
* Jerking of the extremities
* Cyanosis
* Excessive salivation
* Tongue/cheek biting
* Incontinence - In the postictal phase of a Tonic-clonic seizure, how does the patient feel?
-
* Muscle soreness
* Very tired
* May sleep for several
hours
* Patient has no memory of
seizure - Absence/Petit Mal (generalized) seizure usually occur in children or adults?
- Children. Rarely do they continue beyond adolescence.
- Manifestations of absence/Petit Mal seizures include what?

* Brief staring spells
lasting only a few
seconds. - Manifestations of an atypical absence (generalized) seizure include what?
-
* brief warning
* peculiar behavior during
the seizure
* Confusion after seizure - A myoclonic (generalized) seizure is characterized by what?
-
* Sudden, excessive jerk of
the body or extremities
* The jerk may be forceful
enough to hurl person to
ground

may occur in clusters. - Causes of Tonic-Clonic seizures include?

- Akinetic, atonic, and astatic are terms used to describe dropt attacks or falling spells. What are these types of patients at a greater risk for?
- Head injury. Pts. are encouraged to wear helmets
- What do simple partial seizures involve?
- They involve motor, sensory
- What do complex partial seizures involve?
- They involve a variety of behavioral, emotional, affective, and cognitive function.
- The location of the complex partial seizure is normal located where in the brain?
- Temporal lobe
- Partial Seizures can be confined to one side of the brain and remain partial or focal in nature. They also can spread and involve the entire brain. This is called?
- A generalized tonic-clonic siezure.
- Complex partial seizures/temporal seizures manifest how?
-
* clouding of consciousness
* Confused state without
any motor or sensory
components. - How do complex partial seizures differ from simple partial seizures?
- They involve some alteration in consciousness.
- Complex partial seizures/temporal seizures involving confusion without any motor or sensory components is sometimes called?
- Temporal lobe absence
- The most complex partial seizur involves what?
-
* lip smacking and
automatisms (repetitive
movements that may not be
appropriate)
* These are also called
psychomotor seizures - Manifestations of psychomotor/automatisms seizures (aka, complex partial seizures) are?
-
* Continuation of activity
before seizure started.
* picking at clothing
* fumbling with objects
(real or imaginary)
* simply wallking away - Psychosensory symptoms that may occur during a complex partial seizure include:
-

auditory sensations and
vertigo
* there may be alterations
in memory (such as deja
vu)
* Alterations in thought
process
* Alterations in sexual
drive or erectile
dysfunction - What is "Status epilepticus"?
- A state of continuous seizure activity or a condition in which seizures recur in rapid succession without return to consciousness between seizures.

emergency - Status epilepticus is a neurologic emergency why?
