El origen de las convulsiones en pacientes ancianos
JAMA
|September 12, 1977
Resumen
En los adultos mayores que experimentan su primera convulsión, la causa permanece sin identificar en el 50% de los casos. La enfermedad cerebrovascular es la causa identificada más común, que difiere de los estudios previos de epilepsia de inicio en adultos.
Área de la Ciencia:
- Neurología Neurología.
- Geriatría La geriatría es la especialidad de la geriatría.
- Epileptología epileptología.
Sus antecedentes:
- Las convulsiones por primera vez en adultos mayores (≥69 años) presentan desafíos diagnósticos.
- Comprender la etiología de las convulsiones de aparición tardía es crucial para un manejo eficaz.
- Los estudios previos sobre la epilepsia de inicio en adultos pueden no representar completamente a la población anciana.
Objetivo del estudio:
- Investigar las causas de las primeras convulsiones en pacientes ancianos.
- Para comparar la distribución etiológica en este grupo de edad con la literatura existente sobre la epilepsia de inicio en adultos.
- Para determinar la proporción de causas identificables y tratables.
Principales métodos:
- Análisis retrospectivo de 50 pacientes de 69 años o más con una primera convulsión.
- Categoría de los tipos de convulsiones (motor focal frente a generalizado).
- Identificación y clasificación de las causas subyacentes.
Principales resultados:
- Se identificó una causa en solo el 50% de los pacientes.
- La enfermedad cerebrovascular fue la causa más frecuente (30%).
- Se encontraron causas tratables en el 20%; solo se identificó un tumor.
- Las convulsiones motoras focales (56%) tenían una mayor tasa de causa establecida (57%) que las convulsiones generalizadas (44%, 41%).
Conclusiones:
- Una proporción significativa de las primeras convulsiones en los ancianos siguen siendo criptogénicas.
- La enfermedad cerebrovascular es un factor etiológico primario en las convulsiones de inicio tardío.
- El perfil etiológico difiere de las poblaciones adultas más jóvenes, lo que requiere enfoques diagnósticos específicos de la edad.

01:15Drug Dosing: Geriatric Patients
269
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

01:21Drug Dosing: Obese Patients
263
In the United States, obesity is a prominent concern. It is linked to heightened mortality rates due to increased occurrences of conditions such as hypertension, atherosclerosis, coronary artery disease, and diabetes compared to nonobese individuals. A patient is classified as obese if their actual body weight surpasses the ideal or desirable body weight by 20%, based on Metropolitan Life Insurance Company data. Ideal body weights consider average weights and heights for males and females...

01:13Seizures: Classification
1.6K
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:

01:24Epilepsy and Seizures: Overview
1.3K
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...

02:21Cancers Originate from Somatic Mutations in a Single Cell
14.9K
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

3.0K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...
