Study Notes
Amyotrophic Lateral Sclerosis (ALS)
- ALS, also known as Lou Gehrig's disease, is a rapidly progressive neurodegenerative condition
- The state-level age-adjusted average prevalence from 2011-2018 is 2.6 per 100,000 persons in Hawaii, 7.8 per 100,000 in Vermont and 4.4 in the US
- ALS typically affects individuals between 30-60 years of age
- ALS is characterized by upper and lower motor neuron deficits in the limbs due to the degeneration of anterior horn cells in the spinal cord
- Some patients also experience cognitive decline with ALS
- A small percentage (10-17%) of ALS cases are familial and related to several genetic loci
- Diagnosis involves identifying upper motor neuron symptoms like weakness, slowness, hyperreflexia, and spasticity
- Bulbar symptoms may include difficulty chewing, swallowing, coughing, and breathing
- Lower motor neuron symptoms may include weakness, atrophy, fasciculations, incomplete eye closure, and facial weakness, progressing to diaphragmatic weakness and respiratory failure
- Upper motor neuron signs include spasticity, increased tone, hyperreflexia, Babinski sign, clonus, and pseudobulbar affect
- Lower motor neuron signs include muscle atrophy, fasciculations, flaccid weakness, hyporeflexia, and denervation on EMG
- Diagnostic criteria incorporate progressive upper and lower motor neuron symptoms in one limb or body segment or progressive lower motor neuron symptoms in at least two body segments
- Diagnosis requires the absence of other explanations for lower and/or upper motor neuron degeneration. Electromyography (EMG) may show acute on chronic denervation with reinnervation, reduced motor velocity, and normal sensory conduction
- Genetic testing can be diagnostic for SOD1, which accounts for 15% of fALS (familial ALS). EMG is also essential for diagnosis
- Other causes are ruled out by tests like nerve conduction study, MRI, blood/urine tests, lumbar puncture or muscle biopsy
- Patients most frequently have respiratory failure, swallowing difficulties, muscular conditions, issues in communication, and psychological impact
- Patients with ALS have a median survival between 3-5 years from symptom onset
- Bulbar onset of ALS and rapid disease progression typically correlate with poorer outcomes. Younger age and slower progression are associated with longer survival
- Treatment includes riluzole which reduces glutamate-mediated excitotoxicity and modestly extends survival, and edaravone, an antioxidant that may slow functional decline in select patients
- Quality of life is improved via multidisciplinary management, using physical and occupational therapy, speech therapy, palliative care and supportive care
Guillain-Barre Syndrome (GBS)
- GBS is an acute inflammatory demyelinating polyradiculoneuropathy (AIDP)
- GBS can affect all myelinated nerves, including motor, sensory, cranial, and sympathetic nerves
- GBS is a rapid, progressive demyelinating disorder affecting motor neurons
- Two-thirds of those affected reported an antecedent infection 1-3 weeks before the onset of GBS like Campylobacter jejuni, mycoplasma, CMV, EBV, Hepatitis, Flu, HSV, COVID, and Zika
- Symptoms presents include ascending symmetrical progressive proximal weakness over 1-4 weeks, potentially leading to paralysis
- The first symptoms are typically in the legs, then moving to the face, with reduced or absent reflexes
- Patients may experience paresthesia, dysesthesias, back and hip pain
- Autonomic nerve involvement seen include cardiac dysrhythmias, tachycardia, hypotension/HTN, facial flushing, diaphoresis, pulmonary dysfunction, and sphincter control
- Poor prognostic signs in GBS include rapid weakness progression in less than 7 days, a need of assisted ventilation, axonal involvement (shown by decreased amplitudes on NCVs and not just demyelination)
- CSF analysis (after the first week) shows elevated protein but normal cell count, and EMG often shows slowing NCVs
- Management includes supportive care, admission, IVIG or plasmapheresis if ventilation is affected or if the condition is rapidly worsening, and OT/PT. The prognosis for GBS is generally good (~75%), but recovery may take weeks to months
Bell's Palsy
- Bell's Palsy causes facial paralysis of the lower motor neuron type
- The etiology is idiopathic, possibly due to HSV or varicella zoster
- Inflammation involving the facial nerve near the stylomastoid foramen or in the bony facial canal is part of the pathophysiology
- Symptoms are acute onset of facial paralysis and weakness, often with preceding ear pain
- Paralysis of the upper face as well as not being able to wrinkle one's forehead can help differentiate between Bell's Palsy
- Clinical diagnosis is unless presentation is atypical, then EMG, CT scans, or MRI
- Symptoms often involve ipsilateral restriction of eye closure or disturbance of taste/hyperacusis
- Max weakness is typically seen within 3 weeks with resolution within 6 months
- Around 60% of cases will resolve completely without treatment
- Lubricating eye drops or an eye patch is used for symptomatic relief
- Corticosteroids are recommended for all new-onset patients as they improve the chances of recovery. Antivirals are potentially used with herpetic vesicles in ear canal
Myasthenia Gravis (MG)
- MG is more prevalent in young females
- Etiologies include autoimmune disorders, thymic tumors (thymoma), Lambert-Eaton syndrome (small cell lung CA), thyrotoxicosis, RA, or lupus
- MG can cause ocular weakness (ptosis, ophthalmoplegia) or generalized weakness
- Insidious and is exacerbated by concurrent infection and menses
- It involves T-cell mediated block of neurotransmitters by autoAb binding to acetylcholine receptors
- Symptoms involves ptosis, diplopia, difficulty chewing/swallowing, respiratory difficulties, and limb weakness
- Proximal muscles and cranial nerve are most commonly affected
- Presents with fluctuating progressive weakness of voluntary muscles with "early fatigability”, along with potential acute or subacute onset, diurnal fatigue (worse at night), and potentially need for ventilatory support at presentation. There is potential exacerbation from hot conditions and certain prescription drugs
- There is often normal sensation and reflexes
- Diagnosis involves clinical signs and assessment using ice pack tests (cold temperatures improve neuromuscular transmission), Tensilon tests, EMGs
- Diagnosis can be confirmed though serum testing for autobodies to acteylcholine receptor
- Diagnostics for underlying causes includes a CT scan of the chest to test for thymoma
- Management involves acetylcholinesterase inhibitors (pyridostigmine to improve neuromuscular transmission) to avoid cholinergic sx such as increased lacrimation/salivation or bradycardia
- Steroids (prednisone) are an immunological therapy but can be given with steroid-sparing agents (azathioprine)
- During immunomodulation, IVIG and plasmapheresis can be considered for cricis or pre-operative prep
- A thymectomy may also be a management option
- With appropriate management, most patients achieve significant symptom control and have improved quality of life
Muscular Dystrophies (MD)
- Muscular dystrophies involves a group of genetic disorders with mutations affecting dystrophin, laminin, and emerin proteins
- Mutations ultimately lead to impaired muscle fiber stability and degeneration, resulting in progressive muscle weakness
- Duchenne MD (DMD) is X-linked, with early onset and rapid progression
- Becker MD(BMD) is also X-linked, but is milder and has a slower course
- Myotonic dystrophy is autosomal dominant and involves myotonia as well as multi system involvement
- Limb-Girdle Muscular Dystrophies includes a heterogeneous group affecting shoulder and hip muscles
- Progressive weakness, along with calf pseudohypertrophy and Gowers' sign on physical exam can indicate MD
- Lab studies may show elevated creatine kinase (CK)
- Genetic and muscle biopsies will confirm dx. This can be with genetic testing and a muscle biopsy to idendify dystrophin protein abnormalities
- Management is primarily supportive care, including physical therapy, respiratory and cardiac monitoring, and emerging gene therapies
- Duchenne's causes calf enlargement secondary to accumulation of fat
- DMD is caused by an X-linked recessive gene expression and onset at pre-school age
- DMD causes proximal muscle weakness as well as difficulty walking/running or general motion
- Patients also commonly walk on toes
- Death of patients is often the result of respiratory and cardio myopathy by early 20s
- Treatment may include eteplirsen to slow the progression, corticosteroids to improve function, plus standard PT. Myotonic symptoms are often treated with sodium channel blocker.
Complex Regional Pain Syndrome (CRPS)
- CRPS is a rare disorder that includes autonomic and vasomotor instability
- CRPS is usually preceded by surgery or direct physical trauma however can also be caused by any extremity
- CRPS symptoms can involve severe inflammatory reactions to physical trauma, central sensitization, and neuroplastic changes
- Patients present as feeling disproportionate feeling of motor, sensory and trophic sensory change
- Diagnosing CRPS, the following signs presents are burning pain located at the origin site
- Edema and temperature disturbances involving the distrophic nails and limited mobility
- Patients symptoms intensify with certain movement along with skin atrophy
- Testing may involve an x-ray to diagnose and check for osteopienia
- Bone scintigraphy used to sensitive and locate inflammation
- Management includes PT, desensitization techniques, and graded motor imagery to help retain muscle memory
- The patient can also follow pain management techniques and coping strategies
- NSAIDS, anti-convolsants, antidepressants can also be described to eliminate neuropathic symptoms
- Interventional procedures may include sympathetic nerve blocks and neuromodulation techniques
Neuropathies: Overview and Definitions
- Mononeuropathies involve a single peripheral nerve with a focal distribution, and present as local pain, numbness, or weakness and specific inciting event, potentially causing nerve entrapment
- Peripheral Neuropathies affect many nerves with diffuse affects and symmetric, distal pattern of sensory loss with potential motor involvement and diminished reflexes, and typically is related systemic conditions
Examples of Neuropathies
- Mononeuropathies include carpal tunnel, cubital tunnel, radial nerve palsy, peroneal nerve palsy, femoral neuropathy, and Bell's palsy
- Peripheral (poly)neuropathies include diabetic polyneuropathy, alcoholic neuropathy, nutritional neuropathy, uremic neuropathy, Guillain-Barre Syndrome, and hereditary neuropathies
- Mononeuropathies can be diagnosed through physical exams evaluating local causes, electrodiagnostic testing, and ultrasounds or MRI
- Peripheral neuropathies can be diagnosed through metabolic panels, HbA1c, vitamin levels, autoimmune markers, and can be further assisted through skin biopsies or genetic tests
- Treatment for mononeuropathies includes conservative managament (activity modification, splints, and or NSAIDs). Procedures through cortocosteriods or surgery (carpal tunnel)
- Peripheral neuropathies can be treated by finding the address through nutrition, supplementation, or other therapy. Symptomatic treatments can come through physical therapy. There are various doctors that may involved
Comparing Prognosis & Outcomes
- Mononeuropathies often have a favorable outcome if the inciting cause is identified and managed early with a potential for complete recovery after decompression
- Peripheral neuropathies will have a diagnosis that depends on uderlying conditions, with potential need for symptomatic treatment and potential for chronic or reversible treatment
Pediatric Headaches
- Headaches can be categorized as either primary or secondary, acute or chronic depending on presentation and examination
- Primary headaches are the most common cause of headache in children, with migraine and tension-type headache also being commonly found, often chronically
- Triggers are lack of sleep, stress, certain foods, dehydration, or caffeine
- Secondary headaches can appear from increased intracranial pressure, vascular events, head and neck pathology, systemic illness, drug use, and psychological events
- There are also different types of headaches based on symptoms; migrane (auras, throbbing, vomitting, photo/phonophobia, etc), tension (band pain, lack of vomiting, possible phono/photo phobia, etc) and cluster (worse with autonomic dysfunction, several episodes of pain.)
- Severe symptoms in cases such as neurological decline, fever, changes or deformities, imaging (CT scan)
- Diagnosis must be based on the patient's exam, history, and symptomology
- Treatment involves lifestyle factors such as fluids, lack of caffine, proper sleep hygiene, and exercise (massage, PT, Yoga)
- Medication treatments can assist with aborting the headache (NSAIDS), or reduce frequency and intensity, with drugs such as (Topiramate, Propranolol)
