What to Expect at a Neurology Appointment for Suspected Neuropathy

A neurology appointment for suspected peripheral neuropathy typically lasts 45 to 60 minutes for a new patient visit. It follows a predictable structure: a detailed conversation about symptoms and history, a neurological examination, and a discussion of additional testing. This page describes what neurologists ask, what the examination involves, what tests may be ordered, and what questions are worth raising.

What to bring to the appointment

Bringing the right information shortens the time spent reconstructing history and leaves more time for examination and discussion. Five categories are particularly useful.

A complete medication list. Include every prescription medication, over-the-counter drug, vitamin, supplement, and herbal product you take or have taken in the past year, with doses where you know them. Vitamin supplements deserve specific attention: excessive vitamin B6 intake — from a single supplement or cumulative across multiple products — can itself cause peripheral neuropathy. Bringing the actual supplement bottles (or photographs of labels) is more reliable than recalling details from memory, as documented by the NIH Office of Dietary Supplements B6 fact sheet.

A symptom timeline. When symptoms started, how they have evolved, what makes them better or worse, and the impact on daily activities. Specific details neurologists find useful: which areas are affected and in what order, whether symptoms are continuous or intermittent, whether they are worse at any time of day, and what situations change them.

Family history. Whether any close blood relatives have had neuropathy, unexplained nerve pain, balance problems, foot deformities, or genetic conditions affecting the nervous system. Some peripheral neuropathies have inherited components, and family history shapes how broadly the workup considers genetic causes.

Prior test results. Any laboratory results, imaging studies, or prior consultation notes related to the symptoms. Even results that came back normal are useful — they document what has already been excluded.

A list of written questions. Writing questions down beforehand makes them more likely to be asked. A separate page on this site contains a curated list of questions organized by phase of the diagnostic and treatment journey.

What the physician will ask

The history portion of the visit is typically the longest part. The neurologist is characterizing symptoms precisely enough to narrow possible causes and shape the workup. Callaghan and colleagues described the standard history framework for distal symmetric polyneuropathy in a 2015 JAMA review (PMID 26599185).

Onset and progression. When did symptoms first appear? Did they begin gradually or suddenly? Are they getting worse, staying the same, or improving? Was there any specific event around the time of onset — an illness, surgery, medication change, or new exposure?

Distribution. Where in the body are symptoms felt? Did they start in one area and spread? Are both sides affected equally? Symmetric symptoms suggest different causes than asymmetric symptoms.

Quality. What do symptoms feel like — burning, tingling, electric shock, stabbing, numbness, or weakness? Different qualities point to different nerve fiber types being affected.

Severity and functional impact. How bad are symptoms at their worst? Do they interfere with sleep, work, or daily activities? Have you fallen because of balance problems?

Autonomic screening. Questions about constipation, diarrhea, bladder symptoms, lightheadedness when standing, sexual dysfunction, and sweating changes — symptoms pointing to autonomic nerve involvement.

Medication and supplement review. Detailed questions about everything you take, with specific attention to B6-containing supplements. Heavy alcohol use is a recognized cause of neuropathy, so social history is typically included here as well.

What the neurological examination involves

The examination for suspected peripheral neuropathy is conducted at the bedside using simple tools and typically takes 15 to 20 minutes. England and colleagues described the standard elements in the American Academy of Neurology's 2009 practice parameter for evaluating polyneuropathy (PMID 19056666).

Gait and balance. The neurologist watches you walk normally, then walk heel-to-toe, walk on heels, walk on toes, and stand with feet together and eyes closed (the Romberg test, which detects loss of position sense). These assess large-fiber sensory function and motor strength simultaneously.

Sensory testing. Several sensory modalities are tested because each is carried by different nerve fiber types. Light touch maps where sensation is reduced. Vibration sense, tested with a 128 Hz tuning fork, is one of the earliest signs of large-fiber neuropathy — Oh and Brown documented this in a 2003 American Family Physician review (PMID 12882604). Position sense is tested by moving a toe up or down with eyes closed. Pinprick and temperature assess small-fiber function. Protective sensation is tested with a 10-gram monofilament; inability to feel it at the foot is a recognized risk factor for ulceration, particularly in diabetes, as documented by Boulton and colleagues in a 2008 Diabetes Care paper (PMID 18663232).

Reflex testing. Deep tendon reflexes are tested with a reflex hammer. Loss of the ankle reflex is one of the most consistent findings in distal symmetric polyneuropathy.

Strength testing. Pushing and pulling against resistance in various muscles identifies weakness. Foot drop, weakness of toe extension or flexion, and weakness of small hand muscles can all appear in peripheral neuropathy.

Coordination testing. Finger-to-nose and heel-to-shin tests help distinguish peripheral neuropathy from central nervous system causes of balance problems.

Skin and foot inspection. The feet are examined for skin breakdown, calluses, deformities, ulcers, and signs of autonomic involvement such as changes in skin texture or hair loss.

Orthostatic vital signs. Blood pressure and heart rate are measured lying down and standing. A significant drop in blood pressure on standing is a sign of cardiovascular autonomic neuropathy, as defined in the Freeman and colleagues consensus statement (PMID 21431947).

What tests may be ordered and why

Based on history and examination, the neurologist may order additional testing. Callaghan and colleagues reviewed the evidence base for diagnostic testing in distal symmetric polyneuropathy in their 2015 JAMA paper.

Blood tests. A typical initial panel includes hemoglobin A1c and fasting glucose (for diabetes and prediabetes), vitamin B12 with methylmalonic acid, thyroid-stimulating hormone, complete metabolic panel, complete blood count, and serum protein electrophoresis with immunofixation (to detect monoclonal gammopathy). When autoimmune causes are suspected, additional serologies are ordered: ANA, anti-SSA/SSB for Sjögren's syndrome, and ENA panels. When small-fiber neuropathy is suspected, vitamin B6 is checked — Singleton and colleagues documented the link between glucose dysregulation and neuropathy in a 2001 Diabetes Care paper (PMID 11473085).

Nerve conduction studies and EMG. These electrodiagnostic tests assess large-fiber function and can confirm a length-dependent polyneuropathy pattern. Tankisi and colleagues published evidence-based recommendations for electrodiagnostic examination of polyneuropathy in a 2019 Clinical Neurophysiology Practice paper (PMID 31886447). An important limitation: NCS/EMG does not detect small-fiber neuropathy.

Skin punch biopsy. When small-fiber neuropathy is suspected, a 3-millimeter skin sample is sent to a specialized laboratory that counts intraepidermal nerve fibers. Lauria and colleagues published the EFNS/PNS diagnostic guideline for skin biopsy in a 2010 European Journal of Neurology paper (PMID 20642627).

Autonomic function testing. When autonomic involvement is suspected, tests including heart rate variability, tilt table testing, and QSART may be ordered.

Imaging. MRI of the spine or specific nerve roots may be ordered when an alternative diagnosis — such as cervical or lumbar radiculopathy — is being considered or when a focal lesion is suspected.

Insurance and referral logistics

Most insurance plans require a referral from a primary care physician for the neurology visit. The referral typically includes the diagnostic question and any prior workup. Some neurology practices accept self-referral if your insurance allows direct specialist access.

Wait times for a new patient neurology appointment range widely — from a few weeks in some areas to several months in others. For symptoms that are progressing rapidly or are accompanied by significant weakness, contact your primary care physician about whether urgent evaluation is warranted rather than a scheduled appointment.

Follow-up and possible referrals

Depending on findings, the neurologist may arrange follow-up directly, refer to additional specialists, or coordinate care back with primary care. Common referrals include endocrinology (for diabetes or thyroid findings), rheumatology (for autoimmune causes), hematology (for monoclonal gammopathy), podiatry (for foot care when protective sensation is reduced), physical therapy (for balance and exercise prescription), and pain medicine (when chronic pain management is the primary concern).

Questions worth asking your neurologist

1. Based on the examination, what type of neuropathy do you suspect — large-fiber, small-fiber, autonomic, or a combination?
2. What pattern do my symptoms follow — length-dependent, non-length-dependent, focal — and what does that suggest?
3. What tests are you ordering, and what are you hoping each one will tell us?
4. Are there any tests for small-fiber neuropathy that are part of this workup?
5. Have you considered prediabetes or vitamin issues as possible causes?
6. Should I avoid any specific medications or supplements while we work through the diagnosis?
7. What is the next step if the initial tests come back normal?
8. What symptoms should prompt me to call before the next scheduled appointment?
