Study Notes

EEG Data and Patient Confidentiality

EEG data must be protected; all staff are accountable for maintaining patient confidentiality.

Temporal Lobe Epilepsy

Accounts for 60% of all epilepsy cases.

Precocious Puberty

Associated with hypothalamic pathology.

Stroke Signs

Left anterior cerebral artery stroke expected to show right lower extremity sensory loss.

Meningioma

Typically encapsulated tumor.

Bell's Palsy

Characterized by facial paralysis.

Creutzfeldt-Jakob Disease

Defined by dementia, myoclonus, and repetitive discharges (biphasic or triphasic).

Cranial Nerves

Four cranial nerves possess both sensory and motor functions.

West Syndrome Onset

Typical onset around 4 months of age.

Electricity Types

Direct current provides a steady flow of current in one direction.

Electrode Types

Silver-silver chloride electrodes minimize distortion of low frequencies.

Sturge-Weber Disease

Onset usually occurs during infancy.

Homonymous Hemianopsia

Involves loss of the same visual field (left or right) in both eyes.

EEG Source Generation

Most critical source generator of EEG is pyramidal dendritic postsynaptic potentials (PSPs).

Absence Seizure Protocol

Technologist should assess patient's level of consciousness during an absence seizure.

ACTH Treatment

Administered for managing infantile spasms.

Decorticate Posturing

Characterized by bilateral elbow flexion.

Health Care-associated Infections

Reduction addressed by National Patient Safety Goals.

Rolandic Fissure

Separates the motor cortex from the sensory cortex.

Medical History Documentation

Document any recent medical procedures, such as dialysis.

EEG Utility

Most beneficial for evaluating seizure disorders.

Machine Ground Integrity

Life-threatening current can flow through a patient if machine ground is compromised.

ABRET's Code of Ethics

Failing to keep current with technology is a violation.

International 10-20 System

Electrode C6 is located on the right side of the head.

EEG Channel Attenuation

A channel may be single attenuated if inter-electrode spacing is too close.

PLEDS Association

Periodic Lateralized Epileptiform Discharges linked to acute cerebral infarction.

SDS Acronym

Stands for Safety Data Sheet.

Cerebellar Hemorrhage Signs

Clinical signs may include trunkal imbalance and poor coordination.

EEG After Transient Ischemic Attack

Likely shows normal activity within two days following the event.

Diplopia Definition

Refers to double vision.

Important EEG Patient History

Last seizure event is crucial information to document.

Tuberous Sclerosis

A genetic disorder.

Wernicke's Encephalopathy Cause

Resultant of thiamine deficiency.

EEG Activity Generation

Results from both excitatory and inhibitory postsynaptic potentials.

Large Lesion at Optic Chiasm

Can cause total visual loss.

Dysarthria Definition

Describes impaired speech.

Posterior Cerebral Artery Function

Supplies blood to the visual cortex.

Rare Seizure Progression

Transition from Rolandic seizures to absence seizures is uncommon.

Creutzfeldt-Jakob Disease Presentation

Features progressive dementia, bilateral rigidity, myoclonus, stupor, and eventual death.
