Resumen
La mala calidad del sueño en personas con esclerosis múltiple (PSEM) se asocia con más problemas cognitivos autoinformados y una calidad de vida (CdV) reducida, pero no con el rendimiento cognitivo objetivo. Abordar el sueño puede mejorar la CdV de las PSEM.
Área de la Ciencia:
- Neurociencia
- Psicología Clínica
- Medicina de Rehabilitación
Sus antecedentes:
- La esclerosis múltiple (EM) es una enfermedad neurológica crónica que afecta la función cognitiva y la calidad de vida (CdV).
- Las alteraciones del sueño son comunes en personas con EM (PSEM) y pueden afectar su funcionamiento diario.
- La relación entre la calidad del sueño, el rendimiento cognitivo y la CdV en PSEM requiere una mayor investigación.
Objetivo del estudio:
- Comparar la función cognitiva (basada en el rendimiento y autoinformada) entre PSEM con mala calidad de sueño frente a calidad de sueño adecuada.
- Evaluar el impacto de la calidad del sueño en la CdV de las PSEM.
- Determinar si la calidad del sueño predice los resultados de CdV en la EM, controlando los factores relevantes.
Principales métodos:
- Un estudio transversal que involucró a 97 PSEM categorizadas en grupos de mala (n=22) y adecuada (n=72) calidad del sueño.
- La función cognitiva se evaluó mediante pruebas neuropsicológicas y medidas de autoinforme.
- La calidad de vida (CdV) se evaluó utilizando el Functional Assessment of Multiple Sclerosis (FAMS) y la calidad del sueño se midió a través del Sleep Habits Questionnaire.
Principales resultados:
- No se encontraron diferencias significativas en el funcionamiento cognitivo basado en el rendimiento entre los grupos de mala y adecuada calidad del sueño.
- Una proporción significativamente mayor de PSEM con mala calidad del sueño informó dificultades cognitivas en comparación con aquellas con calidad de sueño adecuada (86,36 % frente al 40,28 %, p < 0,001).
- La mala calidad del sueño predijo significativamente la CdV de Síntomas (R²=0,04, p=0,03) y la CdV de Fatiga (R²=0,05, p=0,02) después de controlar la progresión de la enfermedad, la depresión y la fatiga.
Conclusiones:
- La mala calidad del sueño en PSEM se asocia con un aumento de las dificultades cognitivas autoinformadas, no con deterioro cognitivo objetivo.
- La calidad del sueño es un predictor significativo de la CdV, afectando específicamente la percepción de los síntomas y los niveles de fatiga en PSEM.
- Las intervenciones dirigidas a la calidad del sueño pueden ser beneficiosas para mejorar la CdV general en personas con esclerosis múltiple.

01:13Insufficient Sleep and Sleep Deprivation
Insufficient sleep refers to not getting the recommended amount of sleep for optimal functioning, even if it's just slightly less than needed. Sleep insufficiency may occur due to lifestyle choices, such as staying up late for social events or work, resulting in routinely getting less sleep than required. For example, consistently sleeping 6 hours when the body needs 7-9 hours can lead to cumulative effects on health and well-being.

01:27Insomnia
Insomnia is a prevalent sleep disorder characterized by difficulty falling asleep, frequent awakenings during the night, and waking up too early without being able to return to sleep. People with insomnia often experience these disruptions at least three nights a week for at least one month. Chronic insomnia, which lasts for at least three months, can lead to increased anxiety, which in turn can worsen sleep difficulties, creating a cycle of sleeplessness and stress.

01:17Sleepwalking and Sleep Talking
Somnambulism, commonly known as sleepwalking, involves individuals engaging in activities ranging from simple walking to more complex behaviors such as driving. Sleepwalking typically occurs during the slow-wave sleep stages 3 and 4 early in the night when the person is not dreaming, contradicting the myth that sleepwalkers are acting out their dreams.
Factors that increase the likelihood of sleepwalking include sleep deprivation and alcohol consumption. Contrary to common beliefs, it is safe...

01:24Substance Use Disorders Affecting Sleep
Substance use disorders involve a pattern of using drugs more extensively than intended and continuing use despite harmful consequences. This includes legal substances like alcohol and nicotine, as well as illegal drugs. These disorders often involve both physical and psychological dependence, reflecting compulsive use of substances that significantly alter thoughts, feelings, and behaviors, contributing to a major public health issue.

01:27Language and Cognition
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.
01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
