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

* 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
* Seizures are brief and
may occur in clusters.
Causes of Tonic-Clonic seizures include?
* Head Trauma
* Overdose of drugs or
withdrawal of drugs
* Infectious Process
(meningitis, septicemia,
encephalitis)
* Intracranial events
tumors, hemorrhage,
stroke,^ICP)
* metabolic imbalances
* Medical disorders

loss of tone
The term "astatic" refers to what?
Loss of balance
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:
* distortions of visual or
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
