Overview

Differential diagnosis for Myasthenia gravis includes: adult Botulism, infant Botulism, guillian-Barre syndrome, eaton lambert syndrome, electrolyte disturbance, organophosphate poisoning, tick paralysis, tetrodotoxin poisoning, stroke, poliomyelitis, transverse myelitis, neurosyphilis, muscular dystrophy, multiple sclerosis, amyotrophic lateral sclerosisand myositis.

Differentiating Myasthenia Gravis from other Diseases

Myasthenia gravis should be differentiated from other causes of muscle weakness, hypotonia and flaccid paralysis. The differentials include the following:^[1]^[1]^[2]^[3]^[4]^[5]^[6]^[7]^[8]^[9]^[10]^[11]^[12]^[13]^[14]^[15]^[16]

Diseases	History and Physical								Diagnostic tests		Other Findings
Diseases	Motor Deficit	Sensory deficit	Cranial nerve Involvement	Autonomic dysfunction	Proximal/Distal/Generalized	Ascending/Descending/Systemic	Unilateral (UL) or Bilateral (BL) or No Lateralization (NL)	Onset	Lab or Imaging Findings	Specific test	Other Findings

Infant Botulism	+	-	+	+	Generalized	Descending	BL	Sudden	Toxin test	Blood, Wound, or Stool culture	Flaccid paralysis (Floppy baby syndrome), possible respiratory paralysis
Guillian-Barre syndrome	+	-	-	-	Generalized	Ascending	BL	Insidious	CSF: ↑Protein ↓Cells	Clinical & Lumbar Puncture	Progressive ascending paralysis following infection, possible respiratory paralysis
Eaton Lambert syndrome	+	-	+	+	Generalized	Systemic	BL	Intermittent	EMG, repetitive nerve stimulation test (RNS)	Voltage gated calcium channel (VGCC) antibody	Diplopia, ptosis, improves with movement (as the day progresses)
Myasthenia gravis	+	-	+	+	Generalized	Systemic	BL	Intermittent	EMG, Edrophonium test	Ach receptor antibody	Diplopia, ptosis, worsening with movement (as the day progresses)
Electrolyte disturbance	+	+	-	-	Generalized	Systemic	BL	Insidious	Electrolyte panel	↓Ca++, ↓Mg++, ↓K+	Possible arrhythmia
Organophosphate toxicity	+	+	-	+	Generalized	Ascending	BL	Sudden	Clinical diagnosis: physical exam & history	Clinical suspicion confirmed with RBC AchE activity	History of exposure to insecticide or living in farming environment. with : Diarrhea, Urination, Miosis, Bradycardia, Lacrimation, Emesis, Salivation, Sweating
Tick paralysis (Dermacentor tick)	+	-	-	-	Generalized	Ascending	BL	Insidious	Clinical diagnosis: physical exam & history	-	History of outdoor activity in Northeastern United States. The tick is often still latched to the patient at presentation (often in head and neck area)
Tetrodotoxin poisoning	+	-	+	+	Generalized	Systemic	BL	Sudden	Clinical diagnosis: physical exam & dietary history	-	History of consumption of puffer fish species.
Stroke	+/-	+/-	+/-	+/-	Generalized	Systemic	UL	Sudden	MRI +ve for ischemia or hemorrhage	MRI	Sudden unilateral motor and sensory deficit in a patient with a history of atherosclerotic risk factors (diabetes, hypertension, smoking) or atrial fibrillation.
Poliomyelitis	+	+	+	+/-	Proximal > Distal	Systemic	BL or UL	Sudden		PCR of CSF	Asymmetric paralysis following a flu-like syndrome.
Transverse myelitis	+	+	+	+	Proximal > Distal	Systemic	BL or UL	Sudden	MRI & Lumbar puncture	MRI	History of chronic viral or autoimmune disease (e.g. HIV)
Neurosyphilis	+	+	-	+/-	Generalized	Systemic	BL	Insidious	MRI & Lumbar puncture	CSF VDRL-specifc CSF FTA-Ab -sensitive	History of unprotected sex or multiple sexual partners. History of genital ulcer (chancre), diffuse maculopapular rash.
Muscular dystrophy	+	-	-	-	Proximal > Distal	Systemic	BL	Insidious	Genetic testing	Muscle biopsy	Progressive proximal lower limb weakness with calf pseudohypertrophy in early childhood. Gower sign positive.
Multiple sclerosis exacerbation	+	+	+	+	Generalized	Systemic	NL	Sudden	↑CSF IgG levels (monoclonal)	Clinical assessment and MRI	Blurry vision, urinary incontinence, fatigue
Amyotrophic lateral sclerosis	+	-	-	-	Generalized	Systemic	BL	Insidious	Normal LP (to rule out DDx)	MRI & LP	Patient initially presents with upper motor neuron deficit (spasticity) followed by lower motor neuron deficit (flaccidity).
Inflammatory myopathy	+	-	-	-	Proximal > Distal	Systemic	UL or BL	Insidious	Elevated CK & Aldolase	Muscle biopsy	Progressive proximal muscle weakness in 3rd to 5th decade of life. With or without skin manifestations.
