Resumen

Este estudio de caso revela un vínculo entre la epilepsia de ausencia y el trastorno por atracón (TPA) en una mujer de 18 años. El tratamiento de la epilepsia con lamotrigina resolvió los episodios de atracón y mejoró la función cognitiva.

Área de la Ciencia:

Neurociencia
Psiquiatría
Epileptología

Sus antecedentes:

El trastorno por atracón (TPA) a menudo coexiste con afecciones psiquiátricas.
Los factores neurológicos en el TPA siguen siendo poco estudiados.
Los síntomas disociativos son comunes en el TPA.

Objetivo del estudio:

Investigar los posibles fundamentos neurológicos del TPA.
Destacar la importancia de la evaluación neurológica en pacientes con TPA y síntomas específicos.
Explorar la comorbilidad de la epilepsia y el TPA.

Principales métodos:

Informe de caso de una mujer de 18 años con TPA.
Evaluación integral que incluye EEG e neuroimagen para diagnosticar la epilepsia de ausencia.
Pruebas neuropsicológicas para evaluar la función cognitiva.
Tratamiento con lamotrigina (200 mg/día).

Principales resultados:

Se diagnosticó epilepsia de ausencia en una paciente con TPA, lapsos de memoria y alteración de la conciencia.
Se observaron importantes déficits cognitivos en la memoria de trabajo, la velocidad de procesamiento y la atención dividida.
El tratamiento con lamotrigina condujo a la remisión completa de los episodios de atracón asociados con las convulsiones y a mejoras cognitivas.

Conclusiones:

La evaluación neurológica es crucial para los pacientes con trastornos alimentarios con alteración de la conciencia o problemas de memoria.
La actividad epiléptica puede estar relacionada con comportamientos alimentarios desinhibidos.
Se recomiendan enfoques de tratamiento integrados para la comorbilidad de la epilepsia y el TPA.

Binge Eating Disorders

Binge Eating Disorders

Binge eating disorder is a significant mental health condition characterized by recurrent episodes of excessive food consumption within a short period, accompanied by a perceived loss of control over eating behavior. Unlike occasional overeating, binge eating disorder is marked by distressing emotions such as guilt, shame, and anxiety following binge episodes. The disorder affects individuals across different ages and backgrounds, with profound implications for physical and psychological...

Seizures: Classification

Seizures: Classification

Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Epilepsy and Seizures: Overview

Epilepsy and Seizures: Overview

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

What is Behavior?

What is Behavior?

Behaviors are actions that an organism engages in—they can be related to finding food, reproducing, defending against threats, and many other possible actions. Behaviors include activities related to the environment around the animal—such as migration—as well as social interactions within a species or population. Many behaviors involve motor output—that is, muscle movements—while others involve less visible actions, such as learning.

Self-Presentation: Self-Monitoring and Self-Handicapping

People can go to great lengths to protect their self-image and present themselves in ways that they want others to see them. Sociologist Erving Goffman presented the idea that a person is like an actor on a stage. Calling his theory dramaturgy, Goffman believed that we use “impression management” to present ourselves to others as we hope to be perceived. Each situation is a new scene, and individuals perform different roles depending on who is present (Goffman, 1959). Think about...

Behaviorism

Behaviorism

The field of behaviorism was pioneered by figures such as Ivan Pavlov, John B. Watson, and B.F. Skinner fundamentally shifted the focus of psychology to the observable and controllable aspects of human and animal behavior. This shift marked a critical evolution in the discipline, emphasizing scientific rigor and experimental methodology.
The core premise of behaviorism is its focus on observable behavior rather than internal thoughts or feelings. This approach argues that true scientific...
