Autonomic Nervous System Testing

Early symptoms include difficulty grasping objects, constant dropping or clumsiness due to weakness; slurred, slow speech; frequent muscle cramps or twitching; stiffening or tightness of the limbs; and increasing imbalance or loss of the ability to walk.

ALS is diagnosed through a set of tests to rule out other nervous system diseases, including electromyography, nerve conduction tests, MRIs, and spinal fluid analysis.

As ALS advances, symptoms begin in the hands, feet, or legs and then involve other parts of the body, leading to weakness, paralysis, shrinking muscles, and loss of vital body functions.

ALS is not curable, but medicines can help slow progression to a degree and help the patient come to terms with physical limitations.

Most patients live 2–5 years after symptom onset, though some live 10 years or longe,r depending on the speed of progression and respiratory involvement.

ALS affects both upper and lower motor neurons, whereas other motor neuron diseases may involve only one system, leading to distinct patterns of weakness and progression.

It destroys motor neurons in the brain and spinal cord, so signals to voluntary muscles weaken, and muscles shrink and waste away.

Care often involves communication aids, power wheelchairs, home adaptations, psychological therapy, and support groups to restore independence and manage emotional needs.

Yes—clinical trials are ongoing for therapies targeting glutamate imbalance, inflammation, mitochondrial health, and genetic mutations such as SOD1 and C9orf72.

It is a test that records electrical activity in the brain for a number of hours or even days, using electrodes placed on the scalp and a camera so the doctor can observe events and correlate them with brain wave activity.

A routine EEG records 20–40 minutes of activity, while an ambulatory EEG records longer, including during sleep, and allows the patient to walk around during the test.

It helps diagnose episodes that are not typical of seizures but are suspected of being seizures, and helps when patients with epilepsy have breakthrough seizures despite medication.

Patients should wash their hair the day before, avoid styling products, follow medication instructions, and consider wearing a shirt with a front opening.

It can last hours or even days, up to 72 hours, while patients continue their everyday routines.

Electrodes are placed using collodion, covered with a cap or dressing; patients keep notes of symptoms; after the study, the recording is downloaded, and results may take up to a week.

Yes—patients can continue their regular routine for up to 72 hours while wearing the device.

It is safe. Some patients notice mild scalp irritation from the adhesive, but there is no pain and no downtime.

Neurologists review recorded EEG data, video footage, and patient symptom logs to determine whether the abnormal electrical activity matches the reported events.

It improves accuracy by capturing events over longer periods, including sleep, making it more likely to detect seizure activity than a routine EEG.

Early signs include forgetting recent conversations, misplacing items, asking the same question repeatedly, getting lost, or losing track of dates when forgetfulness interferes with daily life.

A neurologist performs a neurological evaluation when memory problems interfere with daily life and may also use cognitive testing, brain imaging, and lab work to rule out other causes.

It is caused by a buildup of abnormal proteins—beta-amyloid plaques and tau tangles—which disrupt how brain cells communicate. Age is the biggest risk, and genetics also increases risk.

Yes—Alzheimer’s is progressive, beginning with mild memory changes and advancing to difficulty with language, decisions, recognition, and later eating, swallowing, and managing other medical issues.

Healthy habits like exercise, a brain-friendly diet, managing blood pressure and blood sugar, staying mentally and socially active, treating hearing/vision issues, good sleep, and stress control can lower the risk or slow its progression.

Treatment includes advanced testing, personalized care plans, symptom-targeting medications, and support for daily functioning and safety.

Alzheimer’s is described as the most common cause of dementia and not a normal part of aging because it involves progressive changes that interfere with daily life.

Staying physically, mentally, and socially active helps patients function better over time; a brain-friendly diet, exercise, sleep, and managing health conditions are also important.

Families are encouraged to seek early neurological evaluation, understand symptoms, and follow guidance for care.

Yes—recent therapies target amyloid and tau proteins, and research continues to explore ways to slow progression and improve early detection through imaging and biomarkers.

Dizziness and balance problems happen when the systems that control balance stop working together. Balance depends on input from the inner ear (vestibular system), vision, joints, muscles, and the nervous system. If any part sends incorrect signal such as from inner ear damage, low blood pressure, neurological disease, infection, or head injury, the brain receives conflicting information, leading to dizziness or instability.

Inner ear causes often produce spinning sensations (vertigo), motion sensitivity, nausea, and difficulty walking straight. Symptoms triggered by head movement or position changes often point toward vestibular causes like positional vertigo. Other causes, such as neurological or circulation problems, may include visual changes, weakness, or coordination issues, which require further testing to separate the cause.

Dizziness becomes concerning if it is sudden, severe, and persistent, or accompanied by weakness, trouble speaking, vision loss, frequent falls to name a few. These may indicate stroke, or other serious conditions that need prompt evaluation.

Common symptoms include brief dizziness, imbalance, nausea, or motion sensitivity. Red flags include repeated falls, confusion, double vision, severe headache, new neurological deficits, or symptoms that steadily worsen over time.

Diagnosis starts with a detailed history and physical exam, focusing on symptoms, triggers, and duration. Specialized vestibular and neurological tests including imaging studies help identify whether the inner ear, central nervous system, or other systems are involved.

Testing may include Videonystagmography (VNG), rotary chair testing, posturography, video head impulse testing, vestibular evoked myogenic potentials, hearing tests, dynamic visual acuity testing, and sometimes MRI or CT scans if a neurological cause is suspected.

Many balance disorders improve significantly with proper treatment. Some resolve fully, while others are managed long-term with therapy, medication, and lifestyle changes, depending on the cause.

BPPV often responds well to repositioning maneuvers such as the Epley maneuver. Vestibular neuritis is managed with medications to reduce inflammation or nausea and vestibular rehabilitation therapy to retrain the brain.

Recovery varies. Some patients improve within days to weeks, while others with chronic or neurological causes may need longer-term therapy and follow-up.

Yes. Hydration, medication review, avoiding triggers, managing blood pressure, and completing vestibular rehabilitation exercises can reduce symptoms and lower recurrence risk.

Common causes include muscle strain, poor posture, prolonged sitting, repetitive movements, bulging discs, arthritis, and age-related degeneration. More serious causes include fractures, infections, tumors, stenosis, or nerve compression.

Muscle pain is often sore or stiff and improves with rest. Disc or nerve pain may radiate into the arms or legs and cause numbness, tingling, or burning sensations. A physical exam and imaging help clarify the source.

Pain is more concerning if it follows trauma, worsens rapidly, or comes with weakness, fever, unexplained weight loss, or bladder or bowel changes.

Sudden limb weakness, loss of bowel or bladder control, severe pain after a fall or accident, fever, or unexplained weight loss require immediate medical attention.

Diagnosis begins with a medical history and physical exam. Imaging such as X-rays, MRI, or CT scans may be used, along with EMG or nerve studies in certain cases.

Most patients improve with conservative treatment such as physical therapy, exercises, posture correction, medications, and lifestyle changes. Surgery is reserved for select cases.

Strengthening core and back muscles improves spinal support, reduces flare-ups, and helps prevent chronic pain.

Many cases improve within weeks. Pain lasting longer than three months is considered chronic and may require ongoing management.

Daily stretching, limiting prolonged sitting, maintaining healthy weight, using supportive workstations, and avoiding repetitive strain reduce spinal stress.

Age-related wear and tear, obesity, smoking, and prolonged desk work increase strain on spinal tissues and slow healing, increasing pain risk.

Symptoms include dizziness, fainting, abnormal sweating, rapid heart rate, temperature instability, and blood pressure problems.

Testing helps identify autonomic dysfunction linked to diabetic neuropathy, autoimmune disease, heart disease, nerve damage, infections, and other autonomic disorders.

You are secured to a table that moves from lying to upright. Some people feel lightheaded or dizzy briefly, but the test is closely monitored for safety.

The full evaluation typically takes 30 minutes to 1 hour, depending on the number of tests performed.

Some medications, caffeine, and nicotine may need to be avoided beforehand to ensure accurate results. Instructions vary by test and your physician will advise you accordingly.

Yes. Testing is performed under medical supervision and is designed to safely assess patients who already experience fainting or blood-pressure issues.

Your neurologist will explain the findings and create a care plan to manage symptoms, address possible underlying causes, and improve autonomic regulation.

Most patients can resume normal activities the same day, although some may need short rest if dizziness occurs during testing.

While not always curable, autonomic dysfunction is manageable with targeted treatment, lifestyle adjustments,

Results are typically reviewed shortly after testing, followed by discussion of findings and next steps with your provider.
