The formation of memories in the brain is an intricate process involving the encoding, storage, and retrieval of information through interconnected neurons. While aging significantly contributes to memory loss by affecting neural pathways, it is not the only factor. Memory can also be impacted by medical conditions, certain medications, and nutritional deficiencies. A lesser-known condition that can indirectly affect memory and brain health is restless legs syndrome (RLS), known for disrupting sleep.

What is restless legs syndrome?

Restless legs syndrome is a neurological condition marked by an irresistible urge to move the legs, often accompanied by sensations like crawling, twitching, or tingling. These symptoms typically surface in the evening or nighttime, especially when an individual is sitting or lying down, thus interfering with sleep quality. According to Dr. Brynna Connor, Healthcare Ambassador at NorthWestPharmacy.com, RLS is frequently misunderstood and often affects women.

What causes restless legs?

The precise cause of RLS remains elusive, but several factors are associated with its development, including genetics, iron insufficiency, hormonal changes, and specific medications. Dr. Connor points out four subtle causes of RLS that women should be particularly mindful of:

1. Iron Deficiency: One of the primary contributors to RLS is a deficiency in iron. Iron is essential for dopamine production in the brain, a neurotransmitter crucial for regulating movement. Insufficient iron levels can lead to impaired dopamine activity, thereby worsening RLS symptoms.

2. Hormonal Changes During Menopause: The hormonal shifts that occur during menopause, particularly fluctuations in estrogen, can trigger or intensify restless legs. Women are particularly susceptible to RLS during pregnancy and menopause, indicating a link between reproductive hormones and the syndrome.

3. Certain Medications: Some medications, including antihistamines and antidepressants, may contribute to or aggravate RLS symptoms. Awareness of medication side effects is essential for managing RLS effectively.

4. Other Deficiencies: Besides iron, deficiencies in magnesium, folate, or vitamin B12 may also play a role in restless legs syndrome by affecting nerve function and muscle control.

Understanding these causes helps in managing RLS through targeted lifestyle changes and medical interventions. For example, addressing iron deficiency through supplements, regulating hormone balance, reviewing medications with a healthcare provider, and ensuring adequate nutrient intake can offer relief. Additionally, non-pharmacological measures like leg massages, warm baths, and regular moderate exercise can alleviate symptoms and improve sleep quality.

In the broader context of memory loss, it is important to recognize that RLS, by disrupting sleep, can indirectly contribute to forgetfulness and cognitive issues. Ensuring good sleep hygiene and managing restless legs symptoms are vital steps toward maintaining both physical comfort and brain health as one ages.

This article aims to shed light on restless legs syndrome’s often overlooked causes and offer simple fixes that women can implement, improving their nightly comfort and overall quality of life.

How Memories Are Formed and Lost

Memories form in the brain through a sequence of stages: encoding (acquiring information), storage (maintaining it), and retrieval (accessing it). The hippocampus is a key brain region involved in this process. Yet, aging reduces neural plasticity and the efficiency of these memory pathways, making recall more challenging over time. Besides aging, medical conditions such as Alzheimer’s disease, stroke, depression, and lifestyle factors like stress and poor sleep contribute to memory loss. Some medications also influence cognitive function, particularly in older adults.

What Is Restless Legs Syndrome? Defining the Condition

Restless Legs Syndrome (RLS) is a neurological disorder that causes uncomfortable sensations in the legs, often described as crawling, tingling, or twitching, prompting an irresistible urge to move. Symptoms usually worsen in the evening and night and when at rest. Movement temporarily relieves discomfort, but the cycle frequently disrupts sleep and quality of life. RLS affects about 5-10% of the population, with a higher prevalence in women, especially during pregnancy and menopause.

Four Sneaky Causes of Restless Legs Every Woman Should Know

1. Low Iron Levels: The Hidden Culprit

Iron deficiency is a well-established factor in RLS due to iron’s critical role in dopamine synthesis. Even mild iron depletion can worsen symptoms, and blood tests often underestimate brain iron levels. Women, especially those with heavy menstrual cycles or pregnancy, are more susceptible to iron deficiency, making this a common but frequently overlooked cause.

2. Hormone Shifts During Menopause

Hormonal fluctuations during menopause, particularly declining estrogen levels, significantly affect neurotransmitter systems involved in RLS. Research indicates that menopausal women experience increased severity and frequency of symptoms, linking hormonal changes to the condition’s onset or worsening.

3. Medications That May Trigger or Worsen RLS

Certain drugs, such as antihistamines, antidepressants, and some blood pressure medications, can provoke or exacerbate restless legs symptoms. Careful medication review with healthcare providers can identify and adjust such triggers, improving symptom control.

4. Other Nutritional Deficiencies Affecting Nerve Health

Deficiencies in magnesium, folate, and vitamin B12 may also contribute by impairing nerve and muscle function. These nutrients support nerve conduction and muscle relaxation, which are vital for preventing involuntary leg movements.

Simple Fixes That Make a Difference

• Iron Supplementation: Especially for women with identified deficiency; consult a healthcare provider for appropriate dosing.

• Hormone Therapy: For menopausal women, hormone replacement may alleviate symptoms but requires medical guidance.

• Medication Review: Adjusting or switching medications under doctor supervision may relieve RLS.

• Dietary Changes: Ensuring sufficient intake of magnesium, folate, and B12 through foods or supplements.

• Lifestyle Adjustments: Regular moderate exercise, avoiding caffeine and alcohol before bed, and maintaining good sleep hygiene.

• Physical Relief: Leg massages, warm baths, heat or cold compresses, and specialized RLS foot wraps can soothe symptoms.

Dr. Brynna Connor’s insights emphasize understanding the unique factors affecting women with restless legs, enabling tailored interventions for better sleep and life quality.

This comprehensive understanding equips women to address restless legs syndrome with informed strategies promoting relief and restful nights. Awareness of how RLS ties into broader issues like memory loss and aging highlights the importance of holistic health care in maintaining overall well-being.

If symptoms persist or worsen, consulting a healthcare professional specialized in sleep or neurological disorders is essential for personalized diagnosis and treatment.
