1 Acupuncture for Neurological Disorders
It matters not whether medicine is new or old, it only matters that it is applied for the benefit of the patient.

2 Neurologic Assessment
Is it a neurologic disease? Seizures Intention tremor CN deficits Head tilt Nystagmus CP deficits Dysmetria Paralysis

3 Minimum Database CBC Chemistry Urinalysis
Bile acids Cholinesterase Urinalysis Chest and abdominal radiographs Abdominal ultrasound Heartworm test Fecal

4 Ancillary Neurologic Tests
Electrodiagnostics EEG EMG BAER CSF tap & analysis Cells & protein Pressure Cholinesterase Titers Radiographs Skull & spinal films Myelography CT scan MRI Muscle Analysis Enzymes 2M antibody Anti-ACH receptor antibody Biopsy

5 When all else fails… Look at the patient!!!

6 Seizures in Small Animals
It is estimated that the overall incidence of seizure disorders in dogs and cats is around 1% In pure breed dogs, this incidence may increase to 15-20%, due to the presence of inherited, primary epilepsy in those breeds

7 Lesion Localization in Seizures
Cerebral Cortex Diencephalon Thalamus Hypothalamus Mesencephalon

8 Seizure Diagnoses

9 Seizure Diagnosis Minimum Database CSF tap & analysis CT or MRI Scan
Abnormal in Reactive Epilepsy CSF tap & analysis Abnormal in Active Secondary Epilepsy CT or MRI Scan Abnormal in Active Secondary Epilepsy EEG Abnormal in Secondary Epilepsy All test are normal in Primary Epilepsy

10 Asymmetrical Seizures

11 Licking Seizure

12 Fly-Biting Seizure

13 Seizures and Signalment
Primary Epilepsy- purebred dogs 1-3 years of age Secondary Epilepsy- any age but especially under 6 months and over 3 years

14 Seizure Treatment Acupuncture alone
Acupuncture in conjunction with drugs Traditional Chinese herbs Western herbal medicine Valerian Root Kava Kava Oats Hops Passionflower Western drugs

15 Phenobarbital Cheap and effective
Dose 2-4 mg/kg for a serum level mcg/ml Takes 3-5 days to reach steady state Safe but can effect the liver in a few cases Controls 80% of seizures

16 KBr (Bromide) Compounded by pharmacist dissolved in H2O at 250mg/ml
Dose at 22 mg/kg q12h Blood level in 2 months between µg/ml Use alone or in conjunction with Phenobarbital Bypass liver Good for cluster seizures

25 Meningoencephalomyelitis
Infectious Diseases Species Specific Steroid Response ME (SRME) Necrotizing Vasculitis (SRMA) Necrotizing ME (NME) Granulomatous ME (GME)

26 Meningoencephalomyelitis
Pain to paresis to plegia Dx with CSF tap Spinal radiographs normal Myelography normal (might be contraindicated)

27 Meningoencephalomyelitis

28 CSF Tap Collection site for seizures is at the cisterna magnum.
Allows analysis for cells, protein and pressure. Cytology and titers for infectious organisms can be obtained.

29 Meningoencephalomyelitis
CSF Analysis may be normal or show increased pressure, protein and/or cells. CSF Titers species specific tests many must be paired with serum titers. CSF cytology form a dog exhibiting a mixed reaction with neutrophils, lymphocytes and macrophages.

30 Meningoencephalomyelitis
Infection virus rickettsia protozoa fungus bacteria Inflammation GME NME SRME SRMA

31 GME Can be: peracute acute & progressive chronic In brainstem, tends to be a multifocal inflammatory disorder Responds temporarily to steroids. Patient with GME presenting with vertical nystagmus, long tract signs, and circling with incoordination.

32 GME GME histologically causes multifocal meningoencephalitis due to proliferation of reticulohistiocytic cells. Lesions also show multinucleated giant cells.

33 Treatment of ME Primor (activated sulfadimethoxine)
Depends upon whether infectious or inflammatory Prednisolone Find minimum daily dose and then used 2 times MDD QOD Primor (activated sulfadimethoxine) 15 mg/kg BID Doxycycline 5-10 mg/kg QD Herbal Support Bromelain/Curcumin 2.5/5 mg/kg TID

42 Horner’s Syndrome Small Animals Large Animals Ptosis Myosis
Enophthalmos Large Animals Facial sweating (horse) Lack of muzzle sweating (cow)

43 Inner Ear Disease Most cases are secondary to bacterial infection (otitis media & interna) extension from otitis externa pharyngitis with extension up the Eustachian tube hematogenous spread

44 Ear Polyps in Cats Benign growth in the external ear canal which causes signs by extension. Can also be pharyngeal mass which grows into middle ear via the Eustachian tube.

45 Ear Polyps in Cats Treatment is surgical removal.
Damage can be permanent, if pressure necrosis has destroyed the inner ear structure.

46 Inner Ear Disease -- TCM
Invasion of external pathogen leading to wind, heat, damp. Heat boils the fluids leading to the accumulation of phlegm. Quiet the wind, reduce heat, disperse damp and activate the blood to dissolve stagnation.

47 Inner Ear Disease -- TCM

Can be wind, heat-damp or wind cold based upon the causative factor involved. Points Constitutional 8 Principle Zang-Fu

55 IVD- -TCM Diagnosis Represents a “bi” syndrome often accompanied by “wei” syndrome Under domain of KID (bones) & LIV (joints & free flow of qi & blood)

56 IVD- - TCM Patterns Excess types Deficient types Wind-Cold-Damp
Blood stagnation Deficient types Yang deficiency Yin deficiency Yin & Yyang deficiency

57 Fibrocartilagenous Emboli
Vascular occlusion from IVD material IVD herniates into the venous sinus or the vertebral body the venous sinuses have no valves increased pressure forces material into spinal cord

58 FCE Generally affects a radicular penetrating branch which leads to a quadrant (wedge) of infarction Many will improve with time

59 Schatzie

60 IVD- -Wind-Cold-Damp Acute invasion of external pathogen leading to stagnation (cold slows blood flow which is worsened by accumulation of damp) Tongue Greasy Pulse Slow & soft Rx principle Dispel W-C-D, activate blood & relieve stagnation TCM herbal Xiao Huo Luo Dan Acupuncture Hua-tuo-jia-ji, BL23, BL67, GB39, GV1, & GV14

61 Acute Spinal Cord Injury
Damage affects the vascular supply leading to ischemia The ischemia leads to lactic acidosis and lipid peroxidation which furthers the injury

62 Pathology of Spinal Injury
Within 5 minutes there are petechiations in the grey matter Progresses to complete hemorrhagic necrosis of the grey matter by 4 hours

63 Pathology of Spinal Injury
From 4-24 hours there is progressive local extension to involve the white matter. If force is great enough, then progresses up & down spinal cord

64 Treatment of Acute SPI Antioxidant steroids (Solu Medral or Solu Delta Cortef) 30mg/kg 15mg/kg every 8 hours for hours Surgical correction Acupuncture needle in wei jian (tip of tail)

65 Intervertebral Disc Disease: chondrodystrophic dogs
Collagen fibers of the nucleus pulposus metamorphs into hyalin cartilage IVD looses elasticity and leads to damage of annulus fibrosus

66 IVD- -chondrodystrophy
Annulus ruptures extruding degenerate nuclear material into the neural canal This leads to pain, paresis or paralysis

67 IVD- -Pain Only Cage Rest for 30 days or 3 weeks after patient becomes clinically normal. Acupuncture Oral steroids and diazepam only under supervision

68 IVD- -Paresis Hospitalize Should improve in first 5-7 days
Prednisolone (2 mg/kg divided 2-3 times a day) Misoprostol 3-4 µg/kg twice a day Diazepam mg/kg TID Should improve in first 5-7 days

69 IVD- -Paralysis with Deep Pain
Emergency Give Solu Medral or Solu Delta Cortef 30 mg/kg Refer May observe for 24 hours to see if dramatic improvement If none, Emergency

70 IVD- -Paralysis No Deep Pain
Emergency Give 30 mg/kg Solu Medral or Solu Delta Cortef Refer 75% respond in first 24 hours 50% in first 72 hours 25% after that

71 Integrative Therapy of IVD Disease
Acute IVD Disease is a surgical emergency Even with no deep pain there is a 75% chance of success within the 1st 24 hours & 50% chance in the 1st 72 hours After 72 hours with no deep pain, the chances are no different Chronic IVD Disease may respond poorly to surgery

72 Hemilaminectomy The thinned lamina is further removed and the laminectomy expanded with rongeurs exposing the spinal cord The area is probed for the problem IVD material

73 IVD After surgery, healing is needed Physical therapy Acupuncture
Passive movements Massage Standing exercises Hydrotherapy Walking Acupuncture Control pain Stimulate nerves Magnet therapy North pole magnet stimulates nerve regeneration Healing touch

74 IVD- -Diet Basic antioxidants Anti-inflammatory membrane stabilizers
Vitamin E, vitamin C, vitamin B complex, selenium, beta carotene Anti-inflammatory membrane stabilizers Omega-3-fatty acids, gamma linolenic acid, coenzyme Q-10 Lecithin to help support myelination Herbal medications to help immune system Astragalus, cordyceps mushroom, garlic Dietary cartilage

111 Treatment Diet Supplements Herbal medications Low carbohydrate
Antioxidants & membrane stabilizers Herbal medications Western- -Canine Cancer formula Traditional Chinese medicine- -Stasis in the Mansion of the Mind

112 Radiosurgery (3D radiation therapy)
McKnight Brain Institute at UF High, single dose radiotherapy 5 arcs of radiation provide sphere of death Based upon the focal size and tissue treated

113 Radiosurgery- -MRI Tumors are identified with MRI
Fusion studies are performed

114 Radiosurgery- -Bite plate
A molded “bite plate” is made for the patient and secured in position Can be taken off and re-applied for later treatment

115 Radiosurgery- -3D alignment
Special orientation system is applied to bite plate before CT scan Infrared cameras are used to align device for radiosurgery

116 Radiosurgery- -CT scan
Fusion CT scan is obtained is bite-plate and alignment guide in place CT guided biopsy is obtained for tissue type

117 Image fusion snapshots
These are 2 examples of image fusion – The images on the left are a fusion scan of a dog with a frontal lobe meningioma, with CT images to the left & MR images to the right. The snapshot on the right is of a cat with an osteosarcoma affecting the frontal sinus – again CT images on the left, MR images on the right. These tools allow you “step through” the images slice by slice, and the sliders allow easy adjustment of the corresponding images.

118 Radiosurgery- -Treatment plan
Fused MRI and CT images provide target Provides anatomic detail of MRI with precision of CT Tumor margins outlined with combined spheres of radiation

119 Treatment plan Treatment plan generated & evaluated in transverse, dorsal and sagittal planes The treatment plan can be generated & evaluated in transverse, dorsal and sagittal planes, using similar tools to the image fusion process. This is a single isodose plan for the meningioma you saw earlier – the red line represents the 80% prescription isodose line, the green line is the 40% isodose line, and the yellow line is the 16% isodose.

120 Radiosurgery- -Treatment
Treatment is applied with LINAC unit at UFBI Cost of radiosurgery procedure is around $ plus workup & conventional surgery

121 Radiosurgery Success Overall ED50 is around 13 months
Some patients survive much longer Prognosis for meningiomas is better than others

122 Cervical Neoplasia Acute or chronic progressive quadriparesis
Usually has neck pain Often in older animals

123 Cervical Neoplasia

124 Cervical Neoplasia

125 Spinal Deformities Hemivertebra Typical butterfly vertebra
May be incidental or cause progressive neurologic disease

126 Hemivertebra CT reconstruction can help determine nature of defects

127 Louis 9 month old GSD Progressive posterior paresis
Also, poor foreleg conformation

128 Hemivertebra May correct by altering the vertebral body (floor of the vertebral canal) using CT-guided surgery

129 Hemivertebra Surgery is performed to stabilize condition and prevent progression Best by dropping the floor of the spinal canal Limitation is angle of deformity

130 Louis

131 German Shepherd Degenerative Myelopathy (GSDM)
A chronic, progressive neurodegenerative disease Initial signs are due to TL spinal cord disease Represents an autoimmune disorder

132 Signalment Breeds Age Sex Onset Clinical Course German Shepherd dogs
Belgium Shepherds Old English Sheepdogs Rhodesian Ridgebacks Weimaraner Probably Great Pyrenes Age > 5 years old (usually 8-9) Sex Equal Onset 1 month to 1 year Clinical Course Paralysis within 3 to 6 month without treatment

133 Early Clinical Signs Mild Spinal Ataxia Rear Leg Weakness
Diminished Proprioception Slight Hyper-reflexia in Rear Legs Rear Leg Weakness Slight Muscle Atrophy Occasionally, Atypical LMN Dysfunction

134 Late Clinical Signs Severe Spinal Ataxia
Conscious Proprioceptive Deficits Unconscious Proprioceptive Deficits Crossed-extensor Reflex Babinski’s Sign

135 Late Clinical Signs Severe Motor Weakness Loss of Weight Bearing
Moderate Rear Leg Muscle Atrophy

136 Signs of GSDM

137 Histopathology Axon and myelin loss Astrocyte proliferation
Swollen axons Patchy demyelination Astrocyte proliferation Increase in vasculature

138 Diagnosis Physical and Neurologic Examination
History of chronic progressive posterior paresis in susceptible breed TL (non-localized) dysfunction

139 Diagnosis EMG Needle EMG- -normal NCV- -normal
Repetitive Nerve Stimulation- -non-decremental Spinal Evoked Potential- -abnormal

140 Spinal Cord Evoked Potential
Normal Early DM Late DM

141 Diagnosis CSF tap (lumbar)  protein with normal cells
Elevated inflammatory proteins  acetylcholinesterase levels (2 X normal) Negative titers for infectious disease

142 Diagnosis Spinal Radiographs Immune Studies
Plain radiographs- -spondylosis & spinal arthritis Myelography- -no significant lesions Immune Studies

143 Humeral Immunity  Circulating Immune-complexes
µg/ml (normal = µg/ml) Contain  non- specific inflammatory proteins on electrophoresis

144 Cell-Mediated Immunity
Attenuated Response to Mytogens ConA Polkweed Mitogen PHA Circulating Suppressor Cells

145 2-D Electrophoresis of CSF
Normal DM

146 CSF Cholinesterase * * normal DM inflam

147 CSF Inflammatory Markers

148 Current Hypothesis An Auto-Immune CNS Disease
Immune-complexes damage endothelium Leads to perivascular fibrin deposition Fibrin degradation leads to leukocyte infiltration Leukocytes produce prostaglandins and leukotreines Leads to Free-Radical production and damage Treatment must take these steps into account

149 Treatment Exercise 20-30 minutes twice a week 1 hour once a week
sustained aerobic exercise is needed  CNS O2 delivery

150 Treatment Dietary Considerations Tofu Fresh vegetables
carrots greens peppers broccoli Ginger, garlic & mustard

151 Treatment Supplements Antioxidants Membrane stabilizers Tonics
Anti-inflammatory

152 Treatment Medication Aminocaproic acid (500 mg TID)
n-Acetylcysteine (25 mg/kg TID QD for 2 weeks, then TID QOD)

153 Conclusion Things that  CNS O2 Availability
Degenerative Myelopathy appears to be an Autoimmune Disease and Treatment must be directed at this Process. Exercise Diet Supplements Medication Things that  CNS O2 Availability

154 Conclusions Acupuncture can help treat or control a number of neurologic diseases Point selection depends upon the constitution of the animal and the nature and location of the disease Patience is still a virtue with neurologic conditions
