Abstract

Insights

Magnetic resonance imaging (MRI) reveals connections between movement disorders and sleep disturbances. Neuroimaging highlights how brain area malfunctions contribute to both motor and sleep issues, aiding diagnosis and understanding.

Area of Science:

  • Neurology
  • Neuroimaging
  • Sleep Medicine

Background:

  • Neuroimaging, particularly magnetic resonance imaging (MRI), is crucial for identifying sleep disturbances.
  • Movement disorders often present with associated sleep disruptions, necessitating advanced diagnostic tools.

Purpose of the Study:

  • To review the role of magnetic resonance imaging (MRI) findings in understanding movement disorders and their associated sleep disturbances.
  • To synthesize current research on the neuroimaging of motor and sleep abnormalities.

Main Methods:

  • Systematic literature review of MRI studies on movement disorders and sleep disruptions.
  • Searched PubMed and Google Scholar (2000-2022) for English publications, including original research and reviews.
  • Included approximately 100 publications focusing on MRI, movement disorders, sleep disorders, and brain region involvement.

Main Results:

  • MRI techniques assess movement disorders like Parkinson's disease (PD), Huntington's disease (HD), and REM sleep behavior disorder (RBD).
  • Specific brain areas are linked to movement abnormalities and related sleep disturbances.
  • A significant overlap exists between mobility disorders and sleep problems, suggesting common underlying neurological causes.

Conclusions:

  • Neuroimaging provides critical insights into the structural and functional correlates of sleep difficulties in movement disorders.
  • Understanding the brain basis of these comorbidities aids in diagnosis and therapeutic strategies.

REM Sleep Behavior Disorder01:15

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...

Sleep-Wake Cycles01:24

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:

Substance Use Disorders Affecting Sleep01:24

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,...

Narcolepsy01:07

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.

Sleepwalking and Sleep Talking01:17

Sleepwalking 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...

Brain Imaging

Brain imaging technologies provide critical insights into both the structure and function of the human brain, enabling medical professionals and researchers to diagnose, study, and treat neurological disorders or psychiatric disorders more effectively.
These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans),  magnetic resonance imaging (MRI),  functional magnetic resonance imaging (fMRI), and Transcranial Magnetic...
