Attention-Deficit/Hyperactivity Disorder

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

Narcolepsy

Narcolepsy

Narcolepsy is a chronic sleep disorder characterized by pervasive, uncontrolled sleepiness and other sleep disturbances. One of its hallmark symptoms is an abrupt transition to REM sleep upon falling asleep, which causes symptoms typically associated with this phase to occur unexpectedly during wakefulness. These include the following symptoms, which typically last from a minute or two to half an hour.

Substance Use Disorders Affecting Sleep

Substance 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.
Understanding the concepts of physical dependence,...

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder

REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.
RBD is significantly associated with...

Management of Insomnia

Management of Insomnia

The sleep cycle, an integral part of human health, consists of several stages with distinct characteristics and functions. It begins with a transition from wakefulness to sleep, known as the light sleep phase, followed by the restorative deep sleep phase, essential for physical recovery and growth. The cycle concludes with the Rapid Eye Movement (REM) phase, characterized by high brain activity and vivid dreaming. Insomnia, a prevalent sleep disorder, involves difficulty falling asleep, staying...

Sleep-Wake Cycles

Sleep-Wake Cycles

Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
NREM Sleep
NREM sleep comprises four progressive stages that seamlessly merge:

Summary

Adults with attention-deficit/hyperactivity disorder (ADHD) often experience sleep issues. This study found differences in sleep quality and fatigue between ADHD subtypes, suggesting tailored treatments may be beneficial.

Background:

Sleep disturbances are prevalent in adults with attention-deficit/hyperactivity disorder (ADHD), affecting over 50% of this population.
The specific associations between sleep and ADHD, particularly across different subtypes, remain poorly understood.
Investigating sleep-related variables is crucial for a comprehensive understanding of ADHD pathophysiology and management.

Purpose of the Study:

To investigate sleep-related variables in adults diagnosed with ADHD.
To compare sleep quality, daytime sleepiness, and fatigue between the predominantly inattentive (ADHD-I) and combined (ADHD-C) subtypes of ADHD.
To explore the interrelationships between sleep quality, daytime sleepiness, and fatigue within each ADHD subtype.

Main Methods:

Utilized the Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), and Fatigue Severity Scale (FSS).
Collected data from 126 adult subjects, comprising 45 with ADHD-I and 81 with ADHD-C.
Employed partial correlation analyses to examine subtype-specific interrelationships between variables.

Main Results:

Approximately 85% of participants reported excessive daytime sleepiness or poor sleep quality.
ADHD-I subtypes reported significantly poorer sleep quality and higher fatigue levels compared to ADHD-C subtypes.
Fatigue associations with sleep quality and daytime sleepiness differed between subtypes, with a notable gender interaction observed in ADHD-I women.

Conclusions:

The interplay between sleep and daytime functioning varies significantly across ADHD subtypes.
These findings highlight the importance of considering ADHD subtypes in understanding sleep disturbances.
Tailored diagnostic and treatment approaches for ADHD may be necessary based on subtype-specific sleep profiles.
