It may be done with instruments, such as lights and reflex hammers. It usually does not cause any pain to the patient. The nervous system consists of the brain, the spinal cord, and the nerves from these areas. There are many aspects of this exam, including an assessment of motor and sensory skills, balance and coordination, mental status the patient's level of awareness and interaction with the environmentreflexes, and functioning of the nerves. The extent of the exam depends on many factors, including the initial problem that the patient is experiencing, the age of the patient, and the condition of the patient.

A complete and thorough evaluation of a person's nervous system is important if there is any reason to think there may be an underlying problem, or during a complete physical. Damage to the nervous system can cause problems in daily functioning. Early identification may help to find the cause and decrease long-term complications. A complete neurological exam may be done:. The nervous system is very complex and controls many parts of the body.

The nervous system consists of the brain, spinal cord, 12 nerves that come from the brain, and the nerves that come from the spinal cord. The circulation to the brain, arising from the arteries in the neck, is also frequently examined. In infants and younger children, a neurological exam includes the measurement of the head circumference.

The following is an overview of some of the areas that may be tested and evaluated during a neurological exam:. Mental status. Mental status the patient's level of awareness and interaction with the environment may be assessed by conversing with the patient and establishing his or her awareness of person, place, and time.

The person will also be observed for clear speech and making sense while talking.

Performing a meaningful neurological exam

This is usually done by the patient's healthcare provider just by observing the patient during normal interactions. Motor function and balance.

This may be tested by having the patient push and pull against the healthcare provider's hands with his or her arms and legs. Balance may be checked by assessing how the person stands and walks or having the patient stand with his or her eyes closed while being gently pushed to one side or the other. The patient's joints may also be checked simply by passive performed by the healthcare provider and active performed by the patient movement.

Sensory exam. The patient's healthcare provider may also do a sensory test that checks his or her ability to feel. This may be done by using different instruments: dull needles, tuning forks, alcohol swabs, or other objects.

Newborn and infant reflexes.

There are different types of reflexes that may be tested. In newborns and infants, reflexes called infant reflexes or primitive reflexes are evaluated. Each of these reflexes disappears at a certain age as the infant grows.

These reflexes include:. Moro's reflex or startle reflex. A quick change in the infant's position will cause the infant to throw the arms outward, open the hands, and throw back the head. Palmar and plantar grasp. The infant's fingers or toes will curl around a finger placed in the area.The neurological examination is one of the most important and cost-effective tools in clinical neurology.

What is a Board-Certified Veterinary Neurologist?

It is important to localise the lesion before considering differential diagnoses, as it is the location of the disease within the nervous system not the disease that determines the clinical signs. Tools useful for the neurological examination include: quiet room, chair, yoga mat, reflex hammer, haemostats, Q-tips, cotton balls, penlight, lens. A full physical examination including an orthopaedic and musculoskeletal examination should be performed prior to a neurological examination.

Any noxious tests such as a rectal exam should be delayed until afterwards. The animal's level of consciousness can be assessed: it may be alert, obtunded, stuporous, semicomatose, comatose. The animal's quality of consciousness may be appropriate or inappropriate, showing compulsion or dementia.

The most common site for a lesion to cause progressive obtundation is the brainstemdue to the presence of the reticular activating system at this level. The animal should be walked or observed to walk on a non-slippery surface. A normal gait requires the integration of proprioceptive and motor systems. Therefore the gait exam is assessing for both paresis and ataxia.

Lower motor neuron paresis : the walk is short-strided, there is a tendency for collapse, bunny hopping and neck flexion. Upper motor neuron paresis : the stride is spastic and there is stiffness.

There are usually proprioceptive deficits as well, which present as knuckling and a swaying gait. Postural reactions require the integration of proprioceptive and motor systems.

Useful reactions to test include: paw positioninghoppingwheelbarrowing, hemiwalking, tactile or visual place and the extensor postural thrust. A deficit in these reactions may show a deficit in conscious proprioception, but a failure to return the paw to a normal position may also be caused by a LMN denervation of the digit extensors or a UMN paresis. It is important to evaluate the tone and spinal reflexes together with the gait abnormality.

Dogs can exhibit profound neuromuscular paresis with myasthenia gravis and still have normal tone and reflexes. Similarly some dogs with T3 - L3 lesions often have normal muscle tone and reflexes. The cutaneous trunci reflex involves pinching the skin on either side of the trunk and assessing contraction of the cutaneous trunci muscle.

A decreased or absent reflex may show: a lesion within the reflex arc, physical limitation of movement due to joint fibrosis or muscle contracture, excitement and fear. An exaggerated reflex may indicate a lesion to UMN pathways cranial to the spinal cord segments tested, or may simply be due to excitement and fear.

The cranial nerve exam should be done when the patient is the most relaxed. It can be done "by the numbers" or by region. Vision can be evaluated by assessing response to dropping cotton wool in front of the animal or watching it follow something in the distance. It assesses cranial nerve II and the forebrain. The menace response is a learned response and may not occur until 10 to 12 weeks in puppies and kittens. This also assesses cranial nerve II, but also the forebrain, cerebellum, brainstem and cranial nerve VII.

Strabismus or abnormal nystagmus may signify lesions in the nerve which are motor to extraocular muscles, such as cranial nerve III, IV and VI.

Facial sensation and integrity of cranial nerve V is assessed with the palpebral reflex and the corneal reflexwhich also involve cranial nerve VII and VI respectively.

Cranial nerve V is also motor to the muscles of mastication and there may be atrophy of these muscles, or an inability to close the jaw. Cranial nerve VII dysfunction may appear as facial paresis or asymmetry. The palpebral reflex and the menace response will be absent. CN VIII dysfunction can lead to deafness, or vestibular signs such as a head tilt or abnormal nystagmus.

Hypoglossal nerve XII dysfunction will be seen as tongue dysfunction, either paresis, atrophy or deviation. Deep pain involves testing periosteal nociception, by applying increased pressure on a digit with haemostats for example.Specializing in Canine and Feline Neurology and Neurosurgery for over 30 years. The primary care veterinarian may contact a doctor at the Veterinary Neurological Center to discuss diagnosis and treatment of patients with neurological disorders.

The veterinarian may decide to treat the patient on-site or refer to the VNC. The primary care veterinarian may recommend with or without consultation from a VNC neurologist that the client bring their pet to the VNC for an examination by a neurologist. Prior to the appointment, the referring clinic should also fax or email the medical history of the patient and give any hard copies including imaging studies that are on film or CD to the owners to bring to their appointment.

Once the owner has received verbal authorization from their primary care veterinarian to come to the VNC, the owner will contact us to schedule an appointment. In the event that diagnostic procedures are recommended, pets should be fasted for 12 hours prior to the appointment when possible to avoid alterations in blood samples e.

Small amounts of water may be provided to avoid dehydration. If your pet is diabetic, consult your veterinarian about feeding prior to the appointment. Your referring veterinarian should advise you as to whether or not you should continue giving any current medications. The owner will fill out the Patient Registration Form. This form can be completed:.

Owners should also bring medication s and hard copies including imaging studies that are on film or CD to the appointment. The doctor will conduct a thorough physical and neurological examination.

Based on their findings, the neurologist will be able to determine what part of the nervous system is most likely being affected, localize the problem to a specific region of the body and make a list of probable neurological disorders that may be causing the presenting signs. In order to effectively treat a specific neurological disorder, the neurologist may recommend diagnostic procedures to rule-out possible causes, localize the problem and confirm the cause of the disorder.

At the time of the appointment, the owner will be given an estimate for services. The Veterinary Neurological Center accepts several different forms of payment: Visa, Mastercard, Discover, American Express, Care Creditcheck in-statemoney order or cashier's check, and cash. Some diagnostic procedures may only require a brief period of time to complete and the owner may wait at the clinic until the testing is finished. Others procedures may require that the patient stay for the entire day or overnight, in which case the owner will pick up their pet at a scheduled time.

Patients who are severely ill or are recovering from surgery require constant care and monitoring by the neurologists and technicians. Hospitalization is often necessary to effectively treat and assist patients recovering from a neurological disease. Once the neurologist and client agree that effective recovery can be maintained by the owner, the patient will go home. At the time of discharge, the owner will receive a Discharge Summary from the neurologist.

The owner may also receive medications and pay the balance of their bill at this time. The referring doctor may choose the method for receiving such correspondence by submitting the Veterinarian Correspondence Form online. Owners may call when they have questions or concerns regarding the neurological status of their pet. Close Menu. Kim Knowles, D.

It is essential to understand our brains in some detail if we are to assess correctly our place in this vast and complicated universe we see all around us. I am currently studying for a feline exam post grad and am trying to yet again get my head around neurology. This site is a god-sent! Thank you so much for this blog. I have learned a lot from it and love the quick, digestible format. Love your website and all the case studies and quizzes. Although, we never stop being students and resources like this are great.

I just wanted to say thank you to the makers of this website.A board-certified veterinary neurologist is an individual that has graduated from veterinary school with a doctorate in veterinary medicine DVMbut has gone on to complete additional specialized training in the field of veterinary neurology.

Veterinary neurology pertains to conditions affecting the brain, spinal cord, muscles, and nerves of animals. You will find board-certified veterinary neurologists at Veterinary Schools and at Private Practices. The training is in the form of a residency that exposes the veterinarian to a variety of neurological diseases affecting a variety of animals.

On completion of a residency an extensive examination process must be passed in order to demonstrate the knowledge necessary to become a board-certified veterinary neurologist. Because animals are not able to voice their concerns the neurological exam is key to determining if, and what part of the nervous system is affected. General practitioners will consult with board-Certified Veterinary Neurologists regarding difficult neurology cases. When more specialized care is required the general practitioner will refer an owner to a board-certified veterinary neurologist.

The board-certified veterinary neurologist works with the general practitioner in a collaborative manner to help diagnose and treat animals with neurological diseases. Theboard-certified veterinary neurologist does not replace the general practitioner, but rather works as a partner with the general practitioner in managing neurological diseases.

Unlike human neurologists, most board-Certified Veterinary Neurologists are trained to not only diagnose diseases of the nervous system, but also have extensive training performing surgeries to address the diseases they diagnose.

Therefore, brain and spinal surgeries are commonly referred to board-Certified veterinary neurologists by general practitioners. This comprehensive approach to managing diseases of the nervous system is a major strength of the board-certified veterinary neurologist.

What to expect at a Specialist.The neurological examination begins at the head and ends at the tail, emphasising the anatomical location of any lesion as the examination proceeds and allowing completion of the examination a lot faster. The examination consists of evaluation of the head and entire body in the stable and finally evaluation of gait and posture while the animal is moving freely in hand.

An evaluation of behaviour, mentation, head posture and movement, as well as cranial nerves, is undertaken to determine if there is evidence of brain or cranial nerve disease Figure 1.

The examiner can complete all the observations, tests and reflexes involving cranial nerve function; the results can be documented and then specific deficits relating to individual nerves can be correlated Table 1. Bony and muscular asymmetry, localised sweating, focal muscle atrophy, decreased pain perception and localised painful responses should be noted. Compressive lesions classically result in clinical signs that appear more severe in the pelvic limbs probably due to the more peripheral location of the spinocerebellar tracts in the spinal cord and a two grade difference in spinal cord ataxia is possible with a lesion in the cervical spinal cord.

After completing the neurological examination, the clinician should decide where within the nervous system any possible lesions exist. If this is not clear, it often is worthwhile returning to the patient and performing more critical evaluations.

Many times, the clinician will be able to define even more precisely the exact location of a lesion, or lesions, within these divisions. With the anatomical location of any lesions more or less clearly determined, and following further review of the history of the case, appropriate specific diseases that might occur at such a site can be considered.

Reflexes tell us only where the lesion is localized.

Veterinary Neurologic Exam

When a deep pain sensation is present, the patient should have a voluntary reaction such as whining, trying to bite or moving away from the painful stimulus. A very stoic patient may show only dilatation of the pupils. The order of these four stages is fixed.

They occur in the same order and always return in the reverse order. Therefore, there is no need to crush a toe in a patient who has motor function. If he has motor function, he has deep pain by definition. Incidentally, these four stages correlate with the anatomy of the spinal cord. Nerve fibers involved with proprioception are located superficially in the cord.

This explains why a mild lesion has mild effects on the patient. A deeper lesion will affect the nerve fibers that control motor function.

And a very severe lesion will apply pressure in the deepest nerve fibers—those that relay deep pain. These four stages help us determine the severity of the lesion. A dog with proprioceptive deficits is mildly affected. At the other end of the spectrum, a dog with no deep pain, to simplify, may have a poor prognosis. Patients may go through these four stages very slowly—over weeks or months—or within days or even hours. Many have been described.

We will again simplify and focus on four common and simple reflexes:.
