Comparative Anatomical Evaluation of Hippocampal Sclerosis in Mesial Temporal Epilepsy

These flashcards cover key concepts related to the study and understanding of Mesial Temporal Lobe Epilepsy and Hippocampal Sclerosis.

Epilepsy

A chronic neurological disorder characterized by recurrent, unprovoked seizures due to abnormal electrical discharges in the brain.

Hippocampal Sclerosis (HS)

A pathological condition involving neuronal loss and gliosis in the hippocampus, strongly associated with drug-resistant epilepsy.

Mesial Temporal Lobe Epilepsy (MTLE)

The most common focal epilepsy in adults, primarily arising from mesial structures of the temporal lobe.

Prevalence

The number of existing cases of a disease in a given population at a specific time.

Incidence

The number of new cases of a disease that occur in a specified time period.

Antiepileptic Drugs (AEDs)

Medications used to treat epilepsy and prevent seizures.

Drug-Resistant Epilepsy (DRE)

Epilepsy that does not respond to adequate trials of two tolerated AEDs.

Cognitive Impairment

Difficulty in processing information, which can affect memory, attention, and learning.

Neuroimaging

Techniques such as MRI or MRS used to visualize the structure and function of the brain.

Epidemiology

The study of how often diseases occur in different groups of people and why.

Morbidity

Refers to the state of being diseased or the prevalence of disease within a population.

Mortality

The state of being subject to death; the death rate in a population.

Auras

Subjective sensations that precede seizures and provide localizing information.

Seizure Semiological Features

Characteristics that describe the presentation and symptoms exhibited during a seizure.

Gliosis

The proliferation of glial cells in response to injury, which can disrupt normal neuronal circuitry.

Neuronal Loss

The death or dysfunction of neurons, leading to various neurological deficits.

Living with Epilepsy

The challenges faced by individuals with epilepsy, including stigma and social exclusion.

Selective Amygdalohippocampectomy

A surgical procedure to remove the amygdala and parts of the hippocampus to treat refractory epilepsy.

Magnetic Resonance Spectroscopy (MRS)

An imaging technique that provides metabolic information about brain tissues.

Quality of Life

The general well-being of individuals; encompasses emotional, social, and physical health.

Pharmacoresistance

Resistance of epilepsy to treatment with antiepileptic drugs, often complicating management.
