Neurological Disorders
What is Neurological Disorders?
Neurological disorders affect the brain, spinal cord, and nerves throughout your body. These conditions can impact how you think, move, feel, and function. Some develop slowly over years, while others appear suddenly.
Your nervous system controls everything from memory and mood to balance and coordination. When something disrupts this system, it can cause a wide range of symptoms. Common neurological disorders include Parkinson's disease, dementia, peripheral neuropathy, and cognitive decline.
Many factors can contribute to neurological disorders. Some are caused by genetics, infections, or injuries. Others develop from long-term exposure to toxic metals like lead, aluminum, or mercury. Nutritional deficiencies, particularly vitamin B12, can also damage the nervous system over time.
Symptoms
- Memory loss or difficulty concentrating
- Numbness or tingling in hands and feet
- Mood changes, including depression or anxiety
- Difficulty with balance or coordination
- Muscle weakness or tremors
- Confusion or disorientation
- Speech difficulties or slurred words
- Headaches or dizziness
- Changes in vision or hearing
- Seizures or loss of consciousness
Some neurological conditions develop gradually, and early symptoms may be mild or barely noticeable. Many people dismiss early warning signs as normal aging or stress. Early detection through blood testing can help identify underlying causes before symptoms become severe.

Causes and risk factors
Neurological disorders have many possible causes. Chronic exposure to toxic metals is a major risk factor. Lead exposure damages nerve cells and disrupts brain function, causing memory loss, mood disorders, and reduced cognitive ability. In severe cases, it can trigger seizures or coma. Aluminum has been linked to Parkinson's disease and dementia, though researchers are still studying this connection. Mercury exposure also harms the nervous system, particularly in developing brains.
Vitamin B12 deficiency is another important cause of neurological damage. Your body needs B12 to maintain healthy nerve cells and produce myelin, the protective coating around nerves. When intrinsic factor blocking antibodies prevent B12 absorption, the deficiency can lead to peripheral neuropathy, memory problems, and cognitive decline. Other risk factors include age, family history, infections, autoimmune conditions, chronic alcohol use, and certain medications.
How it's diagnosed
Diagnosing neurological disorders starts with understanding your symptoms and medical history. Your doctor will perform a physical exam and neurological assessment. Blood tests play a key role in identifying underlying causes, especially nutritional deficiencies and toxic metal exposure.
Rite Aid offers testing for several factors that can contribute to neurological disorders. These include intrinsic factor blocking antibody testing to check for vitamin B12 absorption problems, as well as blood tests for lead, aluminum, and mercury exposure. Identifying these issues early helps you and your doctor create a treatment plan before nerve damage becomes permanent. Additional tests may include brain imaging, nerve conduction studies, or spinal fluid analysis depending on your symptoms.
Treatment options
- Treat underlying vitamin B12 deficiency with supplements or injections
- Reduce or eliminate exposure to toxic metals in your environment
- Chelation therapy to remove heavy metals from your body in severe cases
- Eat a nutrient-rich diet supporting brain health, including fish, leafy greens, and whole grains
- Exercise regularly to improve blood flow to the brain and nervous system
- Manage stress through meditation, yoga, or breathing exercises
- Limit alcohol consumption, as it can worsen nerve damage
- Work with a neurologist for specialized care and monitoring
- Medications to manage symptoms like tremors, mood changes, or pain
- Physical therapy or occupational therapy to maintain function and independence

Frequently asked questions
Early signs include memory problems, difficulty concentrating, numbness or tingling in your extremities, and unexplained mood changes. You might notice trouble with balance, coordination, or finding the right words. Many people experience subtle symptoms for months or years before seeking help. Early testing can identify reversible causes like vitamin B12 deficiency or metal toxicity.
Yes, B12 deficiency is a serious cause of nerve damage. Your body needs B12 to maintain the myelin sheath that protects your nerves. Without enough B12, you can develop peripheral neuropathy, memory loss, confusion, and cognitive decline. The good news is that catching the deficiency early and treating it with supplements or injections can prevent permanent damage.
Lead interferes with how nerve cells communicate and can kill brain cells directly. It disrupts neurotransmitters, the chemical messengers in your brain. Chronic exposure causes memory loss, mood disorders, reduced cognitive ability, and coordination problems. In severe cases, high lead levels can cause seizures, coma, or death.
Several blood tests help identify treatable causes. Intrinsic factor blocking antibody testing shows if your body can absorb vitamin B12 properly. Blood tests for lead, aluminum, and mercury measure toxic metal exposure that damages nerves. These tests can reveal problems before symptoms become severe or irreversible.
It depends on the cause and how early you catch it. Nerve damage from vitamin B12 deficiency is often reversible with treatment if caught early. Removing toxic metal exposure can stop further damage, though existing nerve injury may be permanent. Some conditions like Parkinson's disease are progressive, but early intervention can slow their progression and improve quality of life.
Testing frequency depends on your exposure risk. If you work with metals, live in an older home with lead pipes, or eat high-mercury fish regularly, annual testing makes sense. People with unexplained neurological symptoms should get tested once. Those with known exposure may need more frequent monitoring during treatment.
Fatty fish like salmon and sardines provide omega-3 fatty acids that protect nerve cells. Leafy greens, eggs, and fortified cereals supply B vitamins essential for nerve function. Nuts and seeds offer vitamin E and minerals that support brain health. Berries contain antioxidants that protect against oxidative stress and inflammation in the nervous system.
Healthy lifestyle habits can reduce your risk significantly. Regular exercise improves blood flow to your brain and may protect against cognitive decline. A nutrient-rich diet provides the building blocks your nervous system needs. Managing stress, getting quality sleep, and avoiding toxins like excessive alcohol also help protect your nerves and brain.
See a neurologist if you experience persistent symptoms like memory loss, numbness, tremors, or balance problems. Sudden symptoms like severe headache, vision changes, or difficulty speaking require immediate medical attention. If blood tests reveal vitamin deficiencies or metal toxicity contributing to symptoms, a neurologist can help create a comprehensive treatment plan.
Research suggests a possible connection between aluminum and conditions like Parkinson's disease and dementia. High aluminum levels have been found in brain tissue of people with these disorders. However, scientists are still studying whether aluminum directly causes these conditions or if other factors are involved. Testing your aluminum levels helps identify and reduce unnecessary exposure.
