Getting my PhD in Google

In this day and age, the minute we hear something we don't know about or are diagnosed with something, or even have symptoms of something, the first place we head to is I've been spending a lot of time googling. Sometimes it is too much to handle all at once but it's great to have this info handy 24/7.

Complex Partial Seizures

I liked all of it so I copied and pasted it in here. Good info!

Complex partial seizures cause impaired consciousness and arise from a single brain region. Impaired consciousness implies decreased responsiveness and awareness of self and surroundings. During a complex partial seizure, the patient may not communicate, respond to commands, or remember events that occurred. Consciousness might not be impaired completely. During a complex partial seizure, some patients may make simple verbal responses, follow simple commands, or continue to perform simple or, less commonly, complex motor behaviors such as operating a car. Complex partial seizures typically arise from the temporal lobe but may arise from any cortical region.

Automatisms are quasi-purposeful motor or verbal behaviors that commonly accompany complex partial seizures. The behavior is called quasi-purposeful because it is repeated inappropriately or is inappropriate for the situation. Verbal automatisms range from simple vocalizations, such as moaning, to more complex, comprehensible, stereotyped speech.

Automatisms also may occur during nonepileptic states of confusion (eg, metabolic encephalopathy), after ictus, and during absence seizures. Motor automatisms are classified as simple or complex. Simple motor automatisms include oral automatisms (eg, lip smacking, chewing, swallowing) and manual automatisms (eg, picking, fumbling, patting). Unilateral manual automatisms accompanied by contralateral arm dystonia usually indicates seizure onset from the cerebral hemisphere ipsilateral to the manual automatisms.

Complex motor automatisms are more elaborate, coordinated movements involving bilateral extremities. Examples of complex motor automatisms are cycling movements of the legs and stereotyped swimming movements. De novo automatisms often begin after seizure onset. In other cases, perseverative automatisms occur as repetitions of motor activity that began before the seizure. Bizarre automatisms such as alternating limb movements, right-to-left head rolling, or sexual automatisms may occur with frontal-lobe seizures.

Seizures often begin with a brief aura (simple partial seizure) lasting seconds and then becomes a complex partial seizure. The type of aura is related to the site of cortical onset. Temporal-lobe seizures often begin with a rising abdominal sensation, fear, unreality, or déjà vu. Parietal-lobe seizures may begin with an electrical sensation, tingling, or numbness. Occipital-lobe seizures may begin with visual changes, such as the perception of colored lines, spots, or shapes or even a loss of vision.

Complex partial seizures of the temporal lobe often begin with a motionless stare followed by simple oral or motor automatisms. In contrast, frontal-lobe seizures often begin with vigorous motor automatisms or stereotyped clonic or tonic activity. Extratemporal-lobe seizures may spread quickly to the frontal lobe and produce motor behaviors similar to those associated with complex partial seizures of the frontal lobe. Tonic and dystonic arm posturing may occur in the arm contralateral to the seizure focus. Sustained head or eye turning contralateral to the seizure focus may occur immediately before or simultaneously with clonic or tonic activity elsewhere.

Complex partial seizures often last 30 seconds to 2 minutes. Longer seizures may occur, particularly when the seizures become generalized convulsions. Complex partial status epilepticus may also occur with prolonged episodes of waxing and waning of consciousness.
