Identification and treatment of augmentation in patients with restless legs syndrome: practical recommendations

Sleep Issues in Parkinson's Disease and Their Management

Parkinson's disease (PD) is an alpha-synucleinopathy that leads to prominent motor symptoms including tremor, bradykinesia, and postural instability. Nonmotor symptoms including autonomic, neurocognitive, psychiatric symptoms, and sleep disturbances are also seen frequently in PD. The impact of PD on sleep is related to motor and nonmotor symptoms, in addition to the disruption of the pathways regulating sleep by central nervous system pathology. Rapid eye movement sleep behavior disorder is a parasomnia that can lead to self-injury and/or injury to partners at night. Restless legs syndrome is a subjective sensation of discomfort and urge to move the legs prior to falling asleep and can lead to insomnia and reduced sleep quality. Excessive daytime sleepiness is common in PD and exerts a negative impact on quality of life in addition to increasing the risk of falls. Obstructive sleep apnea is a breathing disorder during sleep that can cause frequent awakenings and excessive daytime sleepiness. Circadian rhythm dysfunction can lead to an advanced or delayed onset of sleep in patients and create disruption of normal sleep and wake times. All of these disorders are common in PD and can significantly reduce sleep quantity, sleep quality, or quality of life for patients and caretakers. Treatment approaches for each of these disorders are distinct and should be individualized to the patient. We review the literature regarding these common sleep issues encountered in PD and their treatment options.

Differential Diagnosis and Treatment of Restless Legs Syndrome: A Literature Review

Restless legs syndrome (RLS) is a chronic neurological disorder affecting a growing number of people. Patients describe an irresistible urge to move their lower limbs in times of immobility. Due to its vague symptoms and similarity to other disorders, it has become increasingly difficult for primary care clinicians to properly diagnose and manage RLS. As a result, patients with RLS are routinely misdiagnosed and continue their lives without proper management. This literature review examines the current understanding of the disorder, provides key points to assist clinicians in differentiating RLS from similar disorders, and explores recently updated evidence-based guidelines for the effective management of RLS.
