Restless legs syndrome in older adults

Area of Science:

• Neurology
• Sleep Medicine
• Geriatrics

Background:

• Restless legs syndrome (RLS) is a prevalent neurological disorder marked by an irresistible urge to move the legs.
• RLS symptoms exhibit significant circadian rhythmicity, worsening in the evening and at night, leading to frequent sleep disturbances and medical consultations.
• The prevalence of RLS escalates with age, affecting an estimated 9% to 20% of the elderly population.

Purpose of the Study:

• To provide an overview of Restless Legs Syndrome (RLS) in the elderly, focusing on its characteristics, prevalence, and management.
• To highlight the importance of age-related factors in RLS presentation and treatment.
• To discuss therapeutic strategies and potential complications in geriatric RLS patients.

Main Methods:

• Literature review of RLS epidemiology, pathophysiology, and treatment options.
• Analysis of age-specific prevalence data for RLS.
• Examination of current pharmacological treatments, including dopaminergic drugs, opioids, and anticonvulsants.
• Consideration of secondary RLS forms and medication interactions in the elderly.

Main Results:

• RLS is common in the elderly, with symptoms worsening at night and causing sleep disturbances.
• Dopaminergic agents are the primary treatment, but opioids and anticonvulsants are also effective.
• Secondary RLS and polypharmacy in older adults necessitate careful treatment individualization.

Conclusions:

• RLS is a significant concern in the geriatric population, impacting sleep and quality of life.
• Current treatments are effective, but careful consideration of age-related factors and drug interactions is crucial.
• Further research into managing RLS in the elderly, particularly concerning secondary forms and polypharmacy, is warranted.
