- Sindroma HORNER dan hipestesi wajah
A. Sindroma TOLOSA - HUNT
B. Sindroma GRANDENIGO
C. Sindroma RAEDER
(C)
Raeder’s para trigeminal neuralgia is often localized adjacent to the trigeminal nerve as it courses through the middle cranial fossa. The cause of this syndrome is often unclear, but it is usually characterized by a partial Horner’s syndrome and unilateral trigeminal nerve problems, including tic-like pain, numbness, and/or masseter weakness. Gradenigo’s syndrome, also known as apical petrositis, often consists of the classic triad of abducens nerve palsy, retroorbital pain, and a draining ear. Tolosa-Hunt syndrome is a diagnosis of exclusion; this condition is believed to result from inflammation adjacent to the superior orbital fissure. It is characterized by painful ophthalmoplegia, cranial nerves III, IV, and VI palsies, and recurrent attacks and remissions; it is typically treated with intravenous steroids (Greenberg, pp. 581-582 )

- Seorang laki-laki berusia 56 tahun dengan riwayat merokok dan hipertensi dibawa kepada seorang neurolog dengan kelainan vaskular yang melibatkan bagian kranial dari nucleus ambiguus. Problem klinis manakah yang seringkali dapat dihindari pada kelainan ini ?
A. Paralisis palatal
B. Paralisis paringeal
C. Paralisis laryngeal
D. Bukan salah satu dari A sampai dengan C
E. A, B dan C semuanya benar
C .
Lesions within the nucleus ambiguus may occur as a result of vascular insults, tumors, syringobulbia, motor neuron disease, and inflammatory disease. Lesions in this location often result in palatal, pharyngeal, and laryngeal paralysis that is often associated with other adjacent cranial nerve and brainstem abnormalities. If the cephalad portion of the nucleus ambiguus is injured, however, laryngeal function is often spared due to the somatotopic organization of this motor nucleus. This is referred to as “palatopharyngeal paralysis of Avellis” (Brazis, pp. 321-322 ) .
5. Kelemahan muskulus trapezius dan sternokleidomastoideus ipsilateral, disponia dan dispagia, hilang rasa pengecap pada sepertiga belakang dari lidah, dan berkurangnya sensasi pada faring merupakan ciri-ciri khas sindroma: A. Collet-Sicard B. Vernet C. Schmidt D. Garcin E. Weber
B.
The spinal accessory nerve enters the j ugular foramen accompanied by cranial nerves IX and X. Lesions of the jugular foramen including tumors, infections, and fractures can result in Verner’s syndrome, which is characterized by ipsilateral trapezius and sternocleidomastoid muscle weakness, dysphonia and dysphagia, loss of taste over the posterior third of the tongue, and depressed sensation over the pharynx (Brazis, pp. 330-331).
6. Seorang anak berusia 7 tahun dibawa ke ruang gawat darurat dengan gejala terus tertawa tanpa dapat dikendalikan (kejang gelastik) dan pubertas prekok. Pemeriksaan MRI otak bisa menunjukkan lokasi kelainan dimana? A. Amigdala B. Hipokampus C. Girus singulate D. Hipotalamus E. Sella turcica
D.
An .MRI study of the brain in a patient with seizures accompanied by involuntary laughter (gelastic seizures) that alternates with crying or sobbing spells would likely show a lesion in the hypothalamus. A small series of cases hm•e been reported in the literature to date describing this phenomenon; in one report, 4 of 16 patients were found to harbor a hypothalamic hemartoma. Gelastic seizures or laughing fits have been reported to occur in up to 2 1 % of patients with hypothalamic hemartomas. Most patients with this lesion present with isosexual precocious puberty by the age of 3 years, although patients as old as 8 years have been reported. Hypothalamic hemartomas may be associated with midline deformities such as callosal agenesis, optic malformations, and hemispheric dysgenesis ( Kaye and Laws, pp. 593-596).

E. Meningitis bakterial ditandai oleh meningitis basal, sementara pada meningitis, basis pada otak relatif bebas infeksi.
E.
Tuberculous meningitis is always secondary to an infection elsewhere in the body, especially the lungs. It differs from infections caused by other common bacteria in that the time course is often more protracted, the mortality rate is higher, and the CSF changes may not be very helpful or diagnostic initially. Tuberculous meningitis is also often characterized by marked basal meningitis, as . opposed to bacterial meningitis, which tends to produce a n;eningeal reaction over the convexities of the brain. The diagnosis is often established by isolating the organism from the CSF. CSF findings include slightly increased pressure, moderate pleocytosis of 25 to 500 cells/mm3 with lymphocytic predominance, increased protein content, decreased glucose values in the range of 20 to 40 mg/dL, and the absence of growth on routine CSF culture media. The natural course of the disease is death within 6 to 8 weeks if left untreated. With early diagnosis and treatment, the recovery rate approaches 90%. Treatment is commonly started with four drugs , including isoniazid, rifampin, pyrazinamide, and ethambutol; streptomycin is an alternative in case one of the agents cannot be used. The drug regimen can be modified later, once sensiti\ •ities of the mycobacterium are known, but are typically administered for 18 to 24 months (Merritt, pp. 108-111).
12. Sindrom GERSTMANN meliputi semua hal di bawah ini, KECUALI A. Agnosia jari B. Akalkulia C. Agrafia D. Kebingungan kanan dan kiri E. Anosognia
E.
Gerstmann’s syndrome can result from injury in the dominant inferior parietal lobule (angular and supramarginal gyri) and is characterized by confusion of the right and left limbs, difficulty in distinguishing the fingers on the hand (finger agnosia) , acalculia, and agraphia. Anosognosia, which is characterized by unawareness of the opposite side of the body, often results from lesions in the nondominant • parietal lobe and is not a feature of Gerstmann’s syndrome (Carpenter, p. 429).
13. Cacad biokimiawi pada penyakit REFSUM telah dipastikan sebagai kekurangan enzim apa? A. Arilsulfatase A B. Pitanoil-koenzim A hidroksilase C. β-glukosilase D. α-galaktosidase E. Asam seramidase
B.
Refsum disease is an autosomal recessive disease caused by a deficiency of phytanoyl-coenzyme A hydroxylase and accumulation of phytanic acid in the body. This disease is unique among the lipidoses because phytanic acid is not synthesized in the body but is obtained exclusively from the diet. Limiting phytanic acid or its precursor, phytol (dairy products, ruminant fat, and chlorophyl-containing foods), from the diet reduces plasma phytanic acid levels. Plasmapheresis may further help eliminate phytanic acid from the body in seYere cases. Symptoms typically begin in childhood but in some patients may be delayed until the fifth decade. Night blindness typically appears first, followed by limb weakness and gait abnormalities. Some patients may develop psychiatric symptoms, peripheral neuropathy, pigmentary retinopathy, deafness, cataracts, bone deformities, or cardiac arrhythmias (Merritt, pp. 514-529 , 539-540 ) .

The symptoms o f acute intermittent porphyria (AlP) are most commonly gastrointestinal, psychiatric, and neurologic. The precise etiology remains uncertain, but large and small nerve fibers, as well as autonomic nerves, have been shown to be affected. Abdominal pain is the most common finding, but often occurs concomitantly with a psychiatric or neurologic disorder. There is usually no abdominal rigidity, but fever, leukocytosis, diarrhea, tachycardia, and hypertension are often evident. Appendicitis or other serious abdominal problems may be difficult to rule out; in fact, some patients have been subjected to laparotomy for abdominal exploration. The most reliable test to confirm AlP is the assay for porphobilinogen deaminase activity in red blood cells, but often a good clinical histor

A. Organisme yang diisolasi dari laring dan paring seringkali adalah Corynebacterium diptheriae
B. Orgaisme-organisme seringkali melepaskan endotoksin yang dapat menyebabkan miokarditis atau neuropati asimetris
C. Neuropati seringkali dimulai dengan gangguan pada fungsi penglihatan
D. Dipteri dan neuropati yang berkaitan dengannya dapat dicegah dengan imunisasi
E. Seringkali menyebabkan neuropati demielinasi
B.
Diphtheria infection produces neuropathy in about 20% of infected patients. Corynebacterium diphtheriae is often isolated from the throat and releases an exotoxin (not endotoxin) that can cause myocarditis or symmetric neuropathy. The neuropathy is often characterized by poor visual accommodation, paresis of. throat muscles, quadriparesis, and slow ner;e conduction velocities secondary to demyelinating neuropathy. This disease can be prevented by immunization and often responds to antibiotics (Merritt, pp. 620-621).

Although \-ernicke’s and Korsakoff’s syndromes are often described together, these appear to be two distinct entities that result from thiamine deficiency. Wernicke’s syndrome consists of mental symptoms (global confusional state) , eye movement problems (nystagmus, lateral rectus palsy, and lateral gaze palsy), and gait ataxia, while Korsakoff’s syndrome is a purely amnestic syndrome usually associated with lesions in the DM nucleus of the thalamus and mammillary bodies. With treatment (thiamine) , ocular abnormalities, nystagmus, and global confusion often improve to varying degrees, leaYing Korsakoff’s amnesia in about 80% of patients. ( Merritt, pp. 924-925).

MELAS, MERFF, LHON, and KSS are a group of disorders related to mitochondrial (mt) DNA abnormalities. Although specific syndromes are often identified by a variety of signs/symptoms, several clinical manifestations seem to be prevalent with mtDNA abnormalities and include short stature, hearing loss, and diabetes mellitus. Lactic acidosis is the most common laboratory finding, while pathologic sectioning reveals enlarged mi tochondria in muscle fibers, which forms the basis for ragged red fibers (RRF) . Leigh’s disease is a disorder of mitochondrial metabolism in which the primary defect involves proteins encoded by nuclear DNA instead of mitochondrial DNA (El l ison, pp. 457-465) .

Wild, involuntary flinging of an extremity may be secondary to a cerebrovascular accident affecting the subthalamic nucleus and is commonly referred to as hemiballismus. Normally, glutamatergic projections from the subthalamic nucleus to the Gpi and SNr suppress the motor nuclei of the thalamus. After damage to the subthalamic nucleus, the thalamic motor neurons are disinhibited and provide excessive activation of the motor cortex. The dopaminergic projections, howeYer, remain intact. pro,•iding a constant and unbalanced acti,•ation of motor neurons throughout the basal ganglia. This is the basis for using neuroleptic agents, including dopamine receptor blockers (haloperidol and perphenazine) and presynaptic dopamine depletors (reserpine and tetrabenazine ) to treat this disease process (Tarsy, p. 9; Pritchard, pp. 330-331).

HD is an autosomal dominant condition with complete penetrance that Yaries in symptom onset from ju,•eniles to late adulthood. \Yith a\•erage onset between 35 and 40 years of age. Sporadic cases of HD are rare. HD, a CHAPTER 3 Neurology Answers 67 trinucleotide repeat (CAG) disorder that localizes to chromosome 4, is more common in males than females and exhibits anticipation (earlier onset in successive generations). The abnormal gene product results in protein conformational changes that lead to aggregation in the cytosol and eventually cellular apoptosis. HD primarily affects the GABNenkephalin projections from the striatum to the external segment of the globus pallidus (indirect pathway) , resulting in thalamic facilitation of motor cortical areas and hyperkinesia. Haloperidol may be effective in suppressing abnormal movements early in the disease course, but the disease is inevitably progressive and usually results in death within 20 years from symptom onset (Merritt, pp. 659-664, 696-699).

Craniosynostosis refers to the premature closure of cranial sutures. It is more common in males than females, and sagittal synostosis accounts for 50% of all cases of craniosynostosis. Sagittal synostosis is identified in a child with an oblong-shaped skull (scaphocephaly or dolichocephaly), which results in an increased AP skull diameter and a narrowed biparietal diameter. There is usually a palpable “keel” along the course of the sagittal suture. Trigonocephaly refers to premature closure of the metopic suture, and results in a wedge-shaped head. Unilateral suture closure (coronal or lambdoid) often results in a misshapen and unilaterally flattened head (plagiocephaly), while premature bilateral coronal or lambdoid suture closure often results in a broad biparietal skull diameter or brachycephaly. Other forms of craniosynostosis can result from premature closure of all the sutures, which can result in a tower-shaped skull (oxycephaly) or a grossly abnormal-appearing skull with a cloverleaf shape (Kleeblattschiidel). Lacunar skull can be seen in patients with Chiari II malformation, and does not result from premature closure of the cranial sutures. The indications for surgery with craniosynostosis are usually for intracranial hypertension (VP shunt) and cosmetic deformity (Wilkins, pp. 3673-3679; Merritt, pp. 491-492) .

Craniosynostosis refers to the premature closure of cranial sutures. It is more common in males than females, and sagittal synostosis accounts for 50% of all cases of craniosynostosis. Sagittal synostosis is identified in a child with an oblong-shaped skull (scaphocephaly or dolichocephaly), which results in an increased AP skull diameter and a narrowed biparietal diameter. There is usually a palpable “keel” along the course of the sagittal suture. Trigonocephaly refers to premature closure of the metopic suture, and results in a wedge-shaped head. Unilateral suture closure (coronal or lambdoid) often results in a misshapen and unilaterally flattened head (plagiocephaly), while premature bilateral coronal or lambdoid suture closure often results in a broad biparietal skull diameter or brachycephaly. Other forms of craniosynostosis can result from premature closure of all the sutures, which can result in a tower-shaped skull (oxycephaly) or a grossly abnormal-appearing skull with a cloverleaf shape (Kleeblattschiidel).

(D)
Progressive multifocal leukoencephalopathy (PML) i s a subacute demyelinating disease that results from reactivation of a papovavirus (JC virus) in immunocompromised patients. The reactivated JC virus infects oligodendrocytes, and results in multifocal areas of demyelination predominantly in the subcortical white mlltter. PML affects 4% of AIDS patients and has been associated with other illnesses characterized by defective cell-mediated immunity, such as lymphomas and leukemias. The lesions of PML are often parieto-occipital, nonenhancing, and exhibit increased signal on T2 and FLAIR MRI with no mass effect. Symptoms of PML depend on the location of lesions and include hemiparesis, visual field cuts, sensory changes, and eventually dementia. The diagnosis of PML is established by biopsy or PCR amplification of JC virus RNA in the CSF. The prognosis of PML is poor, and approximately 80% of patients die within 9 months of symptom onset. Choices A, B, and C are associated with subacute sclerosing panencephalitis (A) and acute disseminated encephalomyelitis ( B and C) (Merritt, pp. 151- 156).

Glycogen storage diseases a Fe primarily autosomal recessive disorders that result from deficiencies of the enzymes im•olved with the metabolism of glucose and glycogen. There are more than 12 different types of glycogenoses; they affect different tissues depending on the expression of the defective enzyme. Type I glycogenosis (Von Gierke’s disease) is characterized by deficiencies of glucose-6-phosphatase and primarily affects the liver. Patients with Von Gierke’s disease present with hepatomegaly and experience severe episodes of hypoglycemia. Type I I glycogenosis ( Pompe’s disease) results from deficiencies of the enzyme acid maltase a.-glucosidase and has three different forms. The infantile type of Pompe’s disease results in hYpotonia, macroglossia, hepatomegaly, cardiomegaly, and death by 2 years of age secondary to cardiac failure. The ju1•enile and adulthood variants of Pompe’s disease are less se1•ere and present with myopathy. Type I I I glycogenosis ( debranching enzyme deficiency or Cori’s disease) is rare and results in hepatomegaly, seizures, and growth retardation in children secondary to deficiencies of the debranching enzyme amylo-1 ,6-glucosidase.

Friedreich’s ataxia (FA) is an autosomal recessive trinucleotide repeat ( GAA) disorder that involves repeat expansion in the frataxin gene, which encodes a mitochondrial protein and is located on chromosome 9q. The onset of symptoms with FA usually occurs by the age of 10 to 15 years; it is usually fatal by the fifth to sixth decades of life. FA results in degeneration of the posterior columns, spinocerebellar tracts, corticospinal tracts, and Clarke’s nucleus in the spinal cord. The medulla (vestibular, cochlear, gracile, and accessory cuneate nuclei), subthalamic nucleus, and pallidum also exhibit evidence of gliosis. Symptoms of FA include ataxic gait, dysarthria, areflexia, lower limb weakness, and loss of vibratory sense and proprioception. Some patients with FA also develop cardiomyopathy, which can lead to cerebellar and cerebral cortical ischemic changes. F.A is associated with the development of peripheral neuropathy as well, with concomitant degeneration of the dorsal root ganglia. Orthopedic deformities, such as hammertoes, kyphoscoliosis, and pes cavus are also common. There is no effective treatment for FA (Merritt, pp. 645-646).

Lesch-Nyhan syndrome ( LNS) is an X-linked recessive disorder of purine metabolism that results from deficiencies of the enzyme hypoxanthine-guanine phosphoribosyltransferase ( HPR’f). Levels of uric acid are increased in LNS secondary to increased purine metabolism, and urate deposition can result in severe nephropathy and gout. Patients with LNS exhibit mental retardation, choreoathetosis, spasticity, self-mutilating behavior, and usually die from renal failure in the second or third decade. Glucose transporter protein syndrome (GTPS) results from deficiencies of the glucose transporter-! protein (GLUT-I ) , which is responsible for the facilitative transport of glucose across the blood-brain barrier. Patients with GTPS exhibit decreased CSF glucose levels (hypoglycorrhachia), seizures, developmental delay, microcephaly, ataxia, and hypotonia. Phenylketonuria is an autosomal recessil•e disorder resulting from phenylalanine hydroxylase deficiency, and cystathionine

Patients with infarcts or trauma involving the corticospinal tracts on one side often develop a hem iplegic gaic characterized by a stiff leg that does not freely flex at the hip, knee, or ankle. With movement, the involved leg tends to rotate outward in a semicircle (circumduction). and the toe and outer side of the sole often become worn (less commonly also seen with steppage gait). The arm on the affected side is also usually weak, and is often carried in a tlexed position iree of any natural movement. Festinating gait is a term used to describe the involuntary acceleration or hastening that often accompanies Parkinson’s patients. Steppage or equine gait is caused by severe weakness or paralysis of the pretibial or peroneal muscles, with difficulty dorsiflexing and everting the foot. The steps are regular and even, but the advancing foot often hangs with the toes pointing down (footdrop) . Walking is accomplished by abnormally high elevation of the involved leg in order for the foot to clear the ground, often producing a characteristic slap as the foot strikes the floor. Waddling gait is characteristic of chronic or progressive muscular dystrophy (Wohlfart-Kugelberg-Welander disease) and congenital hip dislocation. Reeling gait is a term used to describe the gait of a severely intoxicated patient, which sways in many directions with no attempt to correct the staggering by watching the legs or trunk (as in cerebellar or sensory ataxia) . Toppling gait may be seen in patients with brainstem lesions, especially in the elderly with a recent stroke, where sudden lurches forward and frequent falls are a prominent feature. It has also been described as a feature of the lateral medullary syndrome (Wallenberg’s) and in certain patients with progressive supranuclear palsy and advanced Parkinson’s disease. Scissoring gait may result from lesions involving the thoracic spine, where abnormal gait may result from the combined effects of weakness and spasticity. The legs are usually maintained in an extended or slightly flexed position at the hips, and knees are often adducted at the hips. With severe spasticity, the legs may cross in front of each other during ambulation, causing a scissoring gait (Merritt, pp. 46-49; Adams, pp. 94-99) .

Toppling gait may be seen in patients with brainstem lesions, especially in the elderly with a recent stroke, where sudden lurches forward and frequent falls are a prominent feature. It has also been described as a feature of the lateral medullary syndrome (Wallenberg’s) and in certain patients with progressive supranuclear palsy and advanced Parkinson’s disease. Scissoring gait may result from lesions involving the thoracic spine, where abnormal gait may result from the combined effects of weakness and spasticity. The legs are usually maintained in an extended or slightly flexed position at the hips, and knees are often adducted at the hips. With severe spasticity, the legs may cross in front of each other during ambulation, causing a scissoring gait (Merritt, pp. 46-49; Adams, pp. 94-99) .

Patients with infarcts or trauma involving the corticospinal tracts on one side often develop a hem iplegic gaic characterized by a stiff leg that does not freely flex at the hip, knee, or ankle. With movement, the involved leg tends to rotate outward in a semicircle (circumduction). and the toe and outer side of the sole often become worn (less commonly also seen with steppage gait). The arm on the affected side is also usually weak, and is often carried in a tlexed position iree of any natural movement. Festinating gait is a term used to describe the involuntary acceleration or hastening that often accompanies Parkinson’s patients. Steppage or equine gait is caused by severe weakness or paralysis of the pretibial or peroneal muscles, with difficulty dorsiflexing and everting the foot. The steps are regular and even, but the advancing foot often hangs with the toes pointing down (footdrop) . Walking is accomplished by abnormally high elevation of the involved leg in order for the foot to clear the ground, often producing a characteristic slap as the foot strikes the floor.

The lupus inhibitor can be found in up to one-third of systemic lupus erythematosus (SLE) patients . In SLE patients, the associated thrombosis risk can be as high as 10 to 1 5%, while the risk is less in patients without SLE but still in excess of normal. This disease process is associated with deep venous thrombosis of the legs, ischemic strokes in the brain, and miscarriages (placental dysfunction) . Abnormal bleeding does not typically occur, although laboratory findings include prolonged PT and PTT that does not reverse when the patient’s plasma is mixed with normal plasma. Diagnosis can be confirmed by the thromboplastin inhibition test (TTI) and antiphospholipid antibody assays. Treatment to prevent thrombosis may include corticosteroids, antiplatelet drugs, and anticoagulation; plasmapheresis is not typically used. Anticoagulation appears to be the best therapy, with a goal of keeping the INR at least 3 . 0 . Atrial fibrillation and atrial-septal defects are common causes of stroke in certain patient populations, but there is no reason to suspect a rhythm or congenital heart problem in this patient. Multiple sclerosis and metastatic brain tumors are not typically associated with deep venous ‘thrombosis unless the patient is immobilized for a prolonged time ( Merritt, p. 245).

Alzheimer’s disease (AD) is a rare cause of new-onset auditory hallucinations in elderly patients. Typically, other forms of cognitive impairment are present, but hallucinations may occasionally precede other manifestations of this disease process. Low doses of haloperidol are often effective in treating the hallucinations, while medications such as tacrine and donepezil may slow the cognitive decline modestly early in the disease course. Several structures in the brain are affected in AD, including the hippocampus (especially CAl ) , mesial temporal lobe, frontotemporoparietal association areas, and the nucleus basalis of i\leynert (n.b.M) . The degeneration of cells in the n.b.M (and other basal forebrain nuclei) results in decreased•cortical cholinergic input and is associated with decreased levels of ACh and choline acetyltransferase in the hippocampus and neocortex. Patients with AD also exhibit decreased CNS levels of serotonin, norepinephrine, glutamate, and substance P. Ventriculomegaly accompanies the diffuse cerebral neocortical atrophy. Several genes are involved in the pathogenesis of AD including amyloid precursor protein (chromosome 2 1 ) , presenilin 1 (chromosome 14), and presenilin 2 (chromosome 1). The £4 allele of apolipoprotein E (chromosome 19) is associated with an increased risk of developing AD and is associated with 25 to 40% of all cases of AD. In any patient with suspected AD, treatable causes of dementia must be ruled out initially with a good history, physical examination, laboratory data, and imaging studies. Patients with AD are most often diagnosed with a detailed history and physical examination (Merritt, pp. 633 - 637 ) .

A. Penyakit Parkinson dini
B. Atetosis
C. Radikulopati C7
D. Distonia
E. Sindrom saluran Carpal
D .
Writer’s cramp i s a focal dystonia o f unknown etiology. Patients develop sustained muscle contractions that yield abnormal postures or twisting movements when attempting to write. It differs from athetosis by the persistent nature of the abnormal posture or movement. It can be focal (writer’s cramp), segmental (e.g. , face), or rarely multifocal (e.g., face and leg) . Dystonia can also be either primary (inherited) or secondary (stroke, toxin, medication, etc. ) . The medical treatment is variable, often empiric, and can include local botulinum toxin injections, anticholinergics, benzodiazepines, anticonvulsants, lithium , reserpine, baclofen, and levodopa. Micrographia can be seen with Parkinson’s disease but is often accompanied by signs of rigidity, tremor, and bradykinesia. Carpal tunnel syndrome is clue to pressure on the median nerve and is asso.ciated with numbness. weakness, and pain. A cervical radiculopathy rarely if ever presents with the findings seen in this patient; instead. there is pain, weakness, numbness, and ret1ex changes in the distribution of the affected nerve ( Merritt, pp. 669- 6 7 7 )

The F wave and H reflex evaluate certain aspects of nerve conduction. Whereas sensory nerve action potentials (SNAP) and compound muscle action potentials (Ct–1AP) are best at evaluating distal nerves, the F wave and H reflex are the two most commonly used methods in evaluating the proximal portions of nerves. The F wa1•e (F response) measures the entire length of the nerve, including the ventral root. It results from supramaximal stimulus of distal motor nerves with impulse propagation in an antidromic direction. The stimulus tra1•els proximally up the motor nerve and stimulates the anterior horn motor neurons. The variable backfiring of nonreiractory anterior horn cells then results in impulse propagation back down the ventral root and motor nerve to the distal electrode. F-wave latencies are most sensitive for disorders causing generalized or multifocal demyelination (GBS or extensive plexopathies). This is because any focal conduction slowing is diluted by the normal conduction velocity over most of the F-11•ave pathway. The H retlex is the electrical equi1•alent of the stretch retlex and is obtained with submaximal stimulation of the median and tibial nerves. The H reflex therefore involves an afferent (sensory) limb and an efferent (motor) limb, similar to monosynaptic reflex arcs. The H reflex exhibits increased latency in proximal neuropathies and radiculopathies (i.e., C6, C7, or Sl root lesions). Increased H-reflex latencies in conjunction with normal F-wm•e latencies localize lesions to the dorsal roots (Adams, pp. 1022-1025; Merritt, pp. 73-7 6 ) .
