Abstract:

Sensory neuronopathy (SN) presents with sensory ataxia and no weakness. The site of pathology is in the dorsal root ganglia. Electrodiagnostic studies show absence of sensory nerve action potentials and preservation of motor nerve function. Elderly individuals with sensory ataxia and typical electrodiagnostic findings of SN should be evaluated for underlying carcinoma.

Myasthenia Gravis: Diagnostic Tests

Myasthenia gravis is an autoimmune condition affecting neuromuscular transmission, causing generalized weakness in skeletal muscles. Initial diagnoses rely on patients' signs, symptoms, and medical history. The challenge lies in distinguishing myasthenia from other muscular dystrophies. An important diagnostic feature is the significant improvement of symptoms after administering anticholinesterase inhibitors.
The edrophonium test is a diagnostic tool for myasthenia gravis. It involves...
